2.5 Safety in handling with chemical products

Handle chemical products extremely carefully, to avoid potential

injuries and dangers to health, as well as to the environment:

Be very careful, when handling chemical products. Ensure

that you do not have direct contact with chemical products.

Handle chemical products as you would poisons.

Choose chemical products, which are least dangerous to

your health, most effective and easy soluble.

Always read instructions for use, given on the chemical

products. Regard regulations, safety measures and use

instructions.

When working, use respiratory protection, such as gas

mask, helmet with fresh air.

When preparing chemical products, wear appropriate

clothing. When working, use protection mask, gloves, boots

and protection clothing. Be careful with your protection

equipment. Do not use "worn-out" protection.

Make sure that your protection equipment and clothing is in

good condition. Dirty gas mask can cause skin irritation.

Change the filter regularly!

Choose "safer" chemical products. When choosing chemical

products, use products that are less irritant to the skin and

do not cause dust.

When choosing chemical products, prefer products,

which have "safer" packaging;

Prepare chemical products in the fresh air. When preparing products, turn off the

machine to reduce the risk of spilling chemical products.

Prepare chemical products in a wind-free environment or a calm location.

Make sure that the machine is regularly cleaned, to reduce the possibility of direct

contact with chemicals.

During preparation and mixing of chemical products, use tools, intended for this

purposes, litre scale, measuring tools, funnel, bucket. Regularly clean tools.

Do not prepare more chemical products than needed.

Make sure that your working day of using chemical products does not exceed eight

hours. Avoid stress and great physical strains.

Before sprinkling and eight hours after sprinkling do not drink alcohol.

During work with chemical products, do not eat, drink or smoke.

Do not try to free clogged nozzles by blowing with mouth.

In the sprinkling period, heed to spray waiting period.

In case of contact of chemical products with eyes, immediately rinse them with clean

water.

After sprinkling, wash your hands and face well before ingesting food and liquids.

Disable children and animals to access the machine, until it is properly cleaned.

After use, clean the machine properly and store it in a suitable place, so that

unauthorized persons do not have access.

After working with chemical products take a thorough bath.

Clean and wash the machine after each use and before each maintenance procedure.

If you have any health issues while dealing with chemical products, consult your

physician and try to contact the dealer of the chemical product.


page 4

If you have had an accident with a chemical product, we propose the following safety

measures:

eyes and skin: rinse with plenty of clean water,

throat and oesophagus: drink water (not milk!!!),

respiratory paths: fresh air.

2.6 Labels for danger, according to danger level

Packaging of chemical products contains danger signs, which express the danger level. If

possible, avoid chemical products, which have a skull symbol on their packaging or other

symbols, warning about chemically corroding effect. If the packaging has no symbols for

danger, this does not mean the chemical product is not harmful or dangerous. Even if you use

chemical products without danger labels on their packaging, you have to be extremely careful,

because they can be harmful to your health in case of long-term handling.

Danger signs which can be seen on packaging of chemical products:

1 2 3 4 5 6

1. Acute toxicity;

2. Acute toxicity, skin irritation and respiratory tract;

3. Corrosive materials;

4. Oxidising materials;

5. Flammable materials;

6. Explosive materials.

2.7 Danger of mechanical injuries

do not touch the machine while operating;

do not remove safety labels or any other safety equipment of the machine;

do not exceed air pressure in the tyres;

maintain the tyres regularly;

if using the machine in the public traffic you must fit it with lights and other

illuminates in accordance with traffic regulations;

do not enter the tank while preparing or cleaning;

never set working pressure above 15 bar (maximum allowed working pressure);

do not start working until you are sure that there are no unauthorized people in the

vicinity of the machine;

pull out the key from the key-lock after you have finished working to prevent sudden,

unwanted start of the machine.


page 5

2.8 Dangers, caused by liquids under high pressure

Liquids, leaking from the pipes, can be under high pressure and can cause injuries to your

skin, and cause dangerous injuries, if they spread under your skin.

Never try to dismount a hydraulic pipe or any other of the hydraulic installation as long as

this one is under high pressure. Before you start up the hydraulic system make sure that

the installation is safe.

Help yourself with a piece of cardboard when trying to find the place of leakage. Protect

your hands and body by means of gloves and protective clothing if you are handling a

high pressure hydraulic system.

In case of injury, seek medical attention. To prevent severe injuries, each penetration

through the skin must be stopped and liquids must be removed within a few hours.

2.9 Working place of operator

There is only one person required to operate the machine. This person is also the

tractor driver.

This machine can be operated by a person older than 18 years and has the know-how

that is needed for safe and accurate operation of sprinkling appliances and products.

The person needs to be in good health – mentally and physically.

Operational work and maintaining of the sprayer can only be carried out by authorized

personnel, which is qualified for this type of work.

Machine operator must undergo medical examination (in accordance with local

regulations).

The working place of the operator is 1 meter around the machine and tractor.

While sprinkling keep the windows and doors of the tractor closed. It is recommended

that the operator has a hermetically closed cabin which allows the operator to create

overpressure with aeration of fresh air that disables chemically polluted air to enter the

cabin.

While sprinkling, it is recommended that the operator stays in the cabin for about 90-

95% of the time, so the chemical products cannot have influence on his or hers health.

Should the operator notice a change in the working of his or hers organs or feel sick,

he or she should immediately put on the protection breathing mask. However, the best

thing to do is to leave the field and look for shelter in a cleaner area.


page 6

2.10 Personal protection

Machine operator must use well

closed clothing and effective protection

equipment during work.

The operator can come in contact

with chemicals through his or her skin,

mouth or nose. If you do not work safely

even the best protection equipment cannot

be of any use to you.

Safe work with sprayers requires

full attention of machine operator,

therefore, do not listen to music with

headphones on while working.

.

2.11 Protection of respiratory system

There are many different filter and protections masks

available to protect your respiratory system.

It is recommended to use masks that protect the

whole face and are fitted with combinations of

different filters (filter for gas-smoke). An even more

efficient protection can be achieved by means of a

protection helmet in which overpressure can be

created.

Make sure that you are using an appropriate filter:

A (brown): used for most organic chemicals;

B (grey): used for most inorganic chemicals;

P (white): used only for liquid or powder chemicals;

Combination of a brown/white filter with the mark A2P2 in the European Union is

be used for most organic chemicals. The mark A2P2 refers to a combination of

filters which provide appropriate protection against most gases and vapours that

are created by using liquid or powder chemicals. A2 refers to protection class (2)

which means that you can use the filter until it reaches a concentration of 0.5

volume-percentages. P2 refers to gas protection class (2).

The combination B (grey/white) filter must be used in the case of handling

inorganic chemicals.

Before using the mask check the tightness and sealing of it. Check the mask for

damages and make sure that the outer valve is clean and can be closed without any

problems.

Write down the date of the last usage of the filter. The A2P2 filter must be replaced once

a month nevertheless how many times it was used. Filter B must be replaced after every

single use! The filter must be used within 6 months after the packaging of the filter was

opened. Make sure that used filters are destroyed in accordance with local regulations.

WARNING: To prevent inhaling and/or entering the chemicals through the

mouth it is recommended not to eat, drink or smoke while working!


page 7

Never check the efficiency of the filter by smelling:

certain poisonous elements are odourless,

the concentration of the poison cannot always be noticed by human nose,

smelling of certain elements can damage the nasal mucous membrane.

Always check the expiry date of the filter.

2.12 Skin protection

Wear following clothing to protect your skin:

Rubber gloves for agriculture and gardening to protect your hands, which must be long

enough. If the gloves are worn out they need to be replaced. Change the gloves after every

fifth use. Powder the inside of the gloves.

Rubber or neoprene boots that are resistant to water and chemicals.

Overalls that are resistant to water and chemicals and are fitted with a hood. The overall

must cover the ends of gloves and boots.

A waterproof apron for protection of your clothes; in a well protected tractor cabin the

apron can be removed.

A mask that protects the whole face.

Make sure that all of your clothes are well cleaned after every use. Never perform sprinkling

when your clothes are wet, since it can cause a strong contact with your skin. Be very careful

in the case your skin gets injured. After handling chemicals always wash your hands with

soap and loads of water. After you have finished working also wash your face.

2.13 Maintaining protection equipment

After every single use thoroughly clean your protection equipment. Wash the mask, boots,

gloves and working overall with mild soap water and let them dry.

Store your protection equipment in a dry, cold and clean room. Never store your protection

equipment in the same room as the chemicals. Store your protection clothes apart from other

The sprayer pump receives the power from the connecting shaft of the tractor by means of

the cardan shaft. Drive parts can cause serious injuries so, in order to avoid that , follow

the instructions below:

To drive the pump a cardan shaft must be used which characteristics are in

accordance with the recommendations of the manufacturer and is fitted with a

protection cover.

Connect the machine to the tractor only if the drive shaft (PTO) is turned off.

Connecting and disconnecting of the cardan shaft must be performed only when the

engine is shut off.

Before activating the drive shaft (PTO) check the number of revolutions and make

sure that there are no people or animals in the danger area of the machine.

The cardan shaft should be cleaned and greased only when the drive shaft (PTO) is

turned off, the engine shut down and the start key removed.

Do not engage the drive shaft of the tractor (PTO) without a reason and check if the

difference of cardan joint angles is not excessive.

WARNING: Do not engage the drive shaft of the tractor (PTO) with the engine

not running!

2.15 Safe maintenance

Before starting to operate the machine learn how to maintain it.

Keep the working place clean and dry.

Do not grease, maintain or adjust the machine while it is moving! Do not touch

moving parts of the machine! Turn off the machine and make sure that there is no

working pressure in the circulation of the chemicals!

instructions:


page 9

Sprayer, connected to the tractor, can only be transported on the road, when the reservoir

contains no chemical products.

Connect the sprayer to the tractor only if the load on the wheels does not exceed the set

maximum weight. After connecting the machine, at least 20 % of the tractor's weight must

be on driven wheels. You can achieve these values by adding weights at the front and

removing weights at the back of the tractor. You can decide on this on the basis of

weighing before first operation.

Sprayer can completely or partially cover the lights and signs on the tractor. In such case,

the machine must be fitted with light signals and warnings.

During road transport of sprayer with the tractor, follow traffic regulations.

During road transport, sprayer equipment must be raised to appropriate height. Fix the 3-

point hitch in the raised position to prevent sudden fall or slip of the machine and lateral

swinging.

2.17 Procedures in accidents with chemicals

If your skin or eyes come in contact with chemicals or their solution, wash them out with

plenty of water and repeat the process several times.

In the case of suspected poisoning (symptoms: sweating, dizziness, depression, headache,

sickness):

immediately stop working;

take off wet clothes;

remain calm;

if you feel sick because of consumption of chemicals try to throw up;

lay on your side;

immediately call for medical help and let the physician see the label of the chemical, so he

or she will be able to determine the type of poisoning easier.

In case of suspected poisoning the patient must not eat or drink castor oil, milk, butter, eggs

and alcohol, since these ingredients worsen the poisoning effect.

WARNING: To avoid accidents and personal injuries, follow these

recommendations and safety regulations!

Before mounting (connecting of the cardan shaft to the tractor and the sprayer) the

drive shaft – cardan shaft, always turn off the engine and remove the start key

from its lock.

When mounting the cardan shaft, the cardan shaft of the tractor can be easily turned if

the engine and the cardan shaft is turned off.

When mounting the cardan shaft make sure that the safety pin is securely locked. Pull

and push the cardan shaft forwards and backwards until the safety pin locks into place.

Rotating shafts without protection can be very dangerous!

Always make sure that all of the safety devices are on their place and that all of the

rotating surfaces are well covered, including the "joints" of the cardan shaft on both

ends! Do not use cardan shafts without protection!

Do not touch rotating cardan shafts! The safety distance to a rotating cardan should not

be less than 1.5 m.

Secure protection elements with chain from turning!

Make sure that the protection of the cardan on the tractor and connection is well

connected (attached)!

6.2 Connection of cardan shaft

Procedure of first cardan shaft installation:

1. Mount the sprayer to the tractor.

2. Stop (turn off) the tractor’s engine and remove the start key from the lock (start).

3. Use the cardan shaft to connect drive output shaft of the tractor and input shaft on the

sprayer's pump.

4. If the cardan shaft is too long and needs to be shortened, pull out the cardan shaft and

mount each end of it separately to the shaft of the tractor and to the shaft of the sprayer,

measure it out and mark the place where it needs to be cut.

5. Use an appropriate tool to shorten both parts in the same way and remove sharp edges.

6. Attach profiles and connect both parts of the cardan shaft.


page 20

7. Mount the cardan shaft between the tractor and the sprayer.

8. To ensure a long reliability of the cardan shaft, avoid angles greater than 15°.

WARNING: Use protective equipment when handling crop protection

liquids!

The cover consists of one part with lever, through which the float valve mechanism for

ensuring aeration and prevention of water leaking from the tank on the bottom side. The cover

is opened by turning in clockwise direction and closed in reverse order (see marking on the

cover). Tank cover must be closed while working. We recommend using clean water for

filling.

When filling the tank, never insert the hose through cover into the tank or allow contact

between crop protection liquid and filling hose, as pollution of supply part of the hose may

arise. Due to pressure drop, crop protection liquid can flow back to filling hose.

WARNING: Never insert the hose through the cover in the tank or

allow contact of crop protection liquid with the hose, as it may

contaminate it! This can cause pressure drop and suction of crop

protection liquid in the hose!

7.4 Rinsing tank

Intended for washing the tank and other elements after you have finished working or after a

break. Fill the tank only with clean water. You can find more detailed instructions in the

chapter “DESCRIPTION OF VALVE SETTINGS FOR SPRAYING OR CLEANING”.

7.5 Tank for washing hands

Intended for washing hands after handling spray. Fill the tank only with municipal water.

Tank volume is 15 l.

WARNING: Water is not drinkable!

7.6 External filling of tanks

For easier and more convenient filling of tanks with water, the sprayer is equipped with a

special bayonet connection, which enable safe and clean filling. You can fill the main tank

and rinsing tank. Filling of the main tank is additionally protected with a non-return valve (A),

which prevents discharge of crop protection liquid from the tank.

Figure 6: TANK COVER


page 23

Attach hose 50 mm to fitting (A) and secure with hose clamp. Connect fitting (A) with hose

to connection (B) and secure with side levers (see figure 7). Maximum filling capacity is 250

l/min.

7.11 Description of valve settings for spraying or cleaning

7.11.1 Spraying

Use valve for discharge from main tank (pos. 17 – figure 18) to direct crop protection liquid

towards suction valves (pos. 7 – figure 18). The valve must be opened so that the suction if

from the main tank. Turn the three-way valve for excess liquid (pos. 8 – figure 18) so that

crop protection liquid excess travels back to the main tank. Direct selection valve on pressure

line to spraying. AG-TRONIK control valves of opening individual sections. Description of

AG-TRONIK operation is described in chapter “AG-TRONIK”.

Direction of valve flow is marked on the valve lever with an arrow. Setting of valves for

spraying is displayed in the figure below (figure 15).

Figure15: SPRAYING


page 28

7.11.2 Complete cleaning of sprayer

Complete cleaning of sprayer includes cleaning of all internal parts of the sprayer: tank, filter,

pump, regulator and nozzles. Direct clean water through valve for discharge from the tank

(pos. 16 – figure 3) towards the suction valve (pos. 7 – figure 18), which must be directed for

pumping clean water from additional tank. Direct three-way valve for excess liquid (pos. 8 –

figure 18) back towards the main tank, and direct the selection valve to turn on tank rinsing.

At complete cleaning of the sprayer it is advisable to also clean the filling container. Redirect

selection valve in filling container direction and engage valve for use of packaging rinsing

(pos. 8 – figure 11) on the container. After completed cleaning, close the valve and suck water

back into the tank through injector nozzle. Make sure that the cover of filling container is

closed during cleaning!

When you have washed the tank interior and have pumped all the water from the additional

tank, redirect suction valve (pos. 8 – figure 18) to suction from the main tank, and move

selection valve to spraying, to empty the tank through spraying nozzles.

Direction of valve flow is marked on the valve lever with an arrow. Correct setting of valves

for complete cleaning of sprayer is displayed in the figure below (figure 16).

Figure16: COMPLETE CLEANING OF SPRAYER


page 29

7.11.3 Partial cleaning of sprayer

Partial cleaning of sprayer includes cleaning of filter, pump, pressure regulator and nozzles,

without changing crop protection liquid concentration in main tank. Switch valve for

discharge from additional tank (pos. 16 – figure 18) in direction towards suction valve (pos. 7

– figure 18). Direct the valve to suck from the additional tank with clean water. Use three-way

valve (pos. 8 – figure 18) to direct excess water through filter back to the pump and direct the

selection valve to spraying. Clean water has open flow through filter, pump, pressure

regulator and all nozzles, through which the system is completely discharged. Crop protection

liquid concentration in main tank remains the same.

Direction of valve flow is marked on the valve lever with an arrow. Correct setting of valves

for partial cleaning of sprayer is displayed in the figure below (figure 17).

Figure 19: HYDRAULIC DRAWBAR

8 ADDITIONAL EQUIPMENT

8.1 Hydraulic drawbar

As additional equipment, hydraulic drawbar can be installed. Installation is described in the

chapter “CONNECTION OF SPRAYER TO TRACTOR”. Hydraulic drawbar is constructed

for wheels to follow tractor wheels, which enables easy turning and small turning circle.

Complete system enables better control of sprayer and helps when driving on uneven terrain

(transverse inclination of field).

Hydraulic connection operates through two cylinders, which are controlled with control lever

in the tractor.

WARNING: When using the hydraulic drawbar, always activate mechanical

blocking (3) before driving on the road!

8.2 Light signalling, wedges and warning sign for slow vehicles

Light signalling is installed on the rear part of the sprayer. It is fitted with rear light with

reflective triangle and two white reflectors. Connection cable with plug runs to the tractor

cabin. As additional equipment, you can opt for lights with fenders, which help to protect the

sprayer from mud.

As the sprayer is not fitted with brakes, the rear part also has wedges, which are used for

parking the sprayer.

As required by law, the sprayer is also fitted with a sign for slow vehicles on the rear of the

sprayer.

8.3 Set for external washing of spraying device

After completing spraying, the spraying device must be cleaned. The most appropriate place is

next to the area, which was sprayed. This is where the set for external washing of spraying device

is useful.

Connect the fitting to a free fitting on the selection valve to connect the spraying bar with the

spraying device. Turn the selection valve in direction of external cleaning, and set other valves on

the spraying devices in position for partial cleaning of the sprayer (see chapter 7.11.3).

Set includes:

- spraying bar

- flexible hose

- fitting for connecting spraying

bar to main valve

8.4 Suction basket with suction hose

The suction basket is intended for sucking water out of

ponds, creeks, wells, etc. through filter, pump and

selection valve into the main tank. It consists of a

suction basket, 5 m of suction hose and connection for

filter. Install the connection on suction filter by

removing the yellow lever (pos. 3 – figure 10) on the

filter and installing a connection instead, which is fitted

to the suction basket. Then extend the suction hose and

submerge the suction basket in water. Keep in mind

that each metre of height of water surface below the

pump greatly affects on diaphragm load in the pump.

Height difference between pump and extraction surface

should not exceed 3 m. Before activating cardan, close

the three-way valve (pos. 17 – figure 18) at tank exit

(discharge from tank).

Water flows from suction basket through suction filter,

pump, and selection valve into the tank. When the tank is

full, turn off pump drive, remove suction hose, insert

yellow lever (pos. 3 – figure 10) on filter and redirect

three-way valve (pos. 17 – figure 18) into position of

suction from main tank.

WARNING: Retrieve water exclusively from a pool or water reservoir, never from a

hydrant under pressure, as this can damage the pump!

WARNING: When sucking water with suction basket, always use only clean water!

9 PUMPS

WARNING: When sucking water from a pond, be extremely careful, as you can

easily contaminate the water in the pond!

Figure 24: PUMP BM 150

Pumps are a vital element of spraying devices. Reliability

and long durability of the pump also depend on how you

treat the pump and whether you use and maintain it

correctly .

IMPORTANT: The standard version of all pumps is

equipped with diaphragms which are made of NBR

rubber. Therefore it is the user’s duty to use only

chemical agents for spraying which do not harm this kind

of material. On the opposite, the manufacturer cannot be

held responsible for any kind of damage that could occur.

Figure 23: SUCTION BASKET


page 35

9.1 Control before use

When the pump is not operating, check the oil quantity in the housing of the pump. Also

check the oil level every single time before filling the tank. The level must be within the

limits which are marked on the oil lid or in the oil pot (depends on the version of the pump). If

the oil level is too low add some oil whereas be careful not to exceed the maximum allowed

level.

The air pressure in the air chamber depends on the work pressure, displayed in the diagram.

Air pressure in the chamber must never be greater than the pump’s work pressure.

9.2 Use

Before turning on pump drive, make sure that there is enough water in the tank, that all

suction lines are released, that the suction filter is cleaned and that the selection valve on the

pressure line is directed towards nozzles for cleaning the interior of main tank – for system

de-aeration.

WARNING: Never engage pump drive, when AG-TRONIK setting allows full

load of the pump.

Engage drive and let the pump rotate at minimum pressure for about a minute, so that the inlet

and outlet line of the pump de-aerate and only then can you fully load the pump.

Turn the selection pressure valve to desired function.

Be careful not to exceed the maximum allowed pressure and the maximum allowed rpm of

540. On the opposite, the manufacturer cannot be held responsible for any kind of damage

that could occur.

9.3 After use

Some chemical agents can shorten the durability of some vital parts of the pump such as rubber

diaphragms and other rubber seals. Therefore a thorough washing of the pump after each single

spraying is recommended. To do this, you will need to pump some clean water through the pump.

Let the pump operate at working pressure for several minutes. Lower the pressure and let the

pump operate for approximately one minute to blow out the rest of the liquid (pump blow-out).

In the winter, completely discharge water from the pump or protect the pump from freezing (see

chapter “MAINTENANCE AND STORAGE AFTER SEASON”).

Make sure that the valves ensure free flow of liquid

from the tank to the pump. Also check the porosity of

the suction filter insert and the suction hose (make sure

that the hose is not bent).

9.4.1 Oil change

Change the oil for the first time after the first 10-20 working hours and after that every 300

working hours. Also check the diaphragms when changing the oil. Replace damaged or worn

diaphragms with new ones. It is recommended to change the diaphragms every 300 working

hours.

WARNING:

Collect oil in appropriate containers and do not dispose of it in the environment!

9.4.2 Inspection of diaphragms of pump BM 150/20 and BP 171 K

To check the diaphragms, first of all unscrew the bolts on the covers of the pump and release

the suction and pressure collector. After that, unscrew the bolts on the covers and remove the

chambers.

Inspect the upper and lower side of the diaphragms. Release the oil at the same time.


page 37

Figure 26: INSPECTION AND SETTING OF BELT

It is recommended to clean the inside of the pump and its vital parts with gas oil before

reassembling the pump. Assemble the pump in reverse order. Be careful to correctly insert the

valves (see the catalogue). After that, pour fresh oil into the pump. For pump BM 150/20 (BP

171 K), oil needs to be poured in through the oil pot.

While filling oil into the pump, manually turn the shaft of the pump a few times to press

out any excess air between the piston and the diaphragm. Pay attention to the oil level.

Turn on the pump for few minutes at minimum pressure. Pay attention to the functioning of

the pump and add some oil if needed.

9.4.3 Instructions in case of damaged diaphragm

If the oil in the oil pot of pump BM 150/20 whitens, immediately stop operating the machine

and replace the damaged diaphragms. On the opposite, the pump can be heavily damaged. It

is also possible to recognise a damaged diaphragm by means of the manometer, since its

pressure gauge does not come to a halt.

9.4.4 Maintenance

After every single use, it is recommended to wash out the inside of the pump as well as other

parts of the sprayer with clean water (see chapter “DESCRIPTION OF VALVE SETTINGS

FOR SPRAYING OR CLEANING”), and after season, the pump must be prepared for winter

(see chapter “MAINTENANCE AND STORAGE AFTER SEASON – PUMP”).

9.5 Mixing pump C200

Figure 25: PUMP C 200

Sprayer AGS 2500 EN-HP or AGS 3000 EN-HP is equipped as

standard with centrifugal pump, which ensure quality and

constant mixing of crop protection liquid in the tank. Mixing

pump is connected to the main pump with a V-belt. Therefore,

check belt tension occasionally and correct it, if necessary. The

pump also has a greasing point, which must be greased once a

season or every 50 working hours.

In the winter, release water from the pump on the bolt, code:

019.01.104 (see catalogue).

9.6 Inspection and setting of belt on pump C200

Before each use, check tension of belts

between pumps BM150 (BP 171 K)

and C200. If the belt is lacking tension

or is too tight, set it with holder of

centrifugal pump C200 by loosening

nut (marked in figure) and moving the

holder with pump up or down to

tension the belt.

Check belt tension by pressing the belt.

If it moves more than 10-15 mm,

tension it properly!

10.4 Connecting the sprayer to tractor

Spraying equipment is, upon delivery, installed on the sprayer and factory tested.

Installation of sprayer is described in chapter 5.

10.5 Connections to tractor

Tractor cabin must be, at a fixed place, fitted with AG-TRONIK (pos. B – figure 28) for

control of spraying and control panel (pos. D – figure 28) for control of hydraulic cylinders on

spraying equipment.

Connect AG-TRONIK with supply cable to tractor connection with maximum electrical

voltage 12 V DC. Connecting cable, which connects the regulator, must be connected

correctly to AG-TRONIK (description in chapter “AG-TRONIK”). Connect the supply cable

of control panel to AG-TRONIK and check connection cable between the control panel and

solenoid valve.

Connect hydraulic hoses to hydraulic valves of the tractor through hydraulic clamps. To

prevent incorrect connection, the hoses are colour coded (see chapter 10.3.4).

Hydraulic hose for lifting/lowering of spraying equipment is, against blocking of hydraulic

clamp on hydraulic hose of sprayer, equipped with ball valve, which must be closed during

connection/disconnection of hydraulic hose with hydraulic connection!

WARNING: When connecting hydraulic hoses, hydraulic valves must not be

under pressure!

10.6 Mechanical transport safeties of spraying booms

Spraying equipment is equipped with mechanical safety, which prevents uncontrolled opening

of side booms in transport position. Transport position of spraying equipment is determined

accurately and mechanically secured in this position by mechanical safeties, fitted to sprayer’s

chassis. The sprayer with spraying equipment functions as a harmonious whole. When lifting

the spraying equipment, mechanical safeties release and you can control all hydraulic

functions. Mechanical safeties function automatically and are conditioned only with lifting of

Figure 32: TRANSPORT SAFETIES


page 44

spraying equipment and function only when it is folded, when closing the equipment, it must

be raised to end position, folded with the help of electrohydraulic control and then lowered

onto mechanical safeties, so they become functioning. Pay attention to spraying equipment lie

down on the front safeties only, the last need to be raised from 5 to 10 cm!

WARNING: Incorrectly folded spraying equipment in transport position does not

ensure safety from uncontrolled opening of booms during transport!

page 45

10.7.1 Hydraulic lifting parallelogram and vertical suspension

Hydraulic lifting parallelogram is the same for all spraying equipment. Hydraulic cylinders

operate in one way. Choke valve on distribution cube, which is attached to sprayer’s chassis,

ensures lifting speed. Hydraulic lifting parallelogram enables operation of spraying equipment at

the height area of 1.90 m.

Vertical suspension in ensured by hydraulic accumulator, which is attached to distribution cube,

on the sprayer’s chassis. Accumulator absorbs shocks or reduces forces on spraying equipment

and is filled with nitrogen.

The hydraulic lifting parallelogram blockage blocks or prevents the equipment from lowering

to the ground during transport. It is automatically operated and activates when the spraying

equipment is closed: It deactivates when the equipment is opened.

WARNING: Equipment is under pressure!

page 46

10.7.2 Side damping

Side forces, which occur during driving on the spraying equipment, are controlled by

polyurethane springs, installed between boom holder and fastening holder of the boom. It is

important that the springs are equally pre-tensioned, to ensure setting of spraying equipment, in

case of side tilting, in original position.

Polyurethane springs are factory pre-tensioned – factory length of spring with washers is 90±3

mm. If the sprayer does not return to original position correctly, the springs must be correctly pre-

tensioned by tightening/loosening the nut, so that the equipment is perpendicular to the chassis.

When a spring loses its elastic properties (becomes stiff), it must be replaced.

10.7.3 Two-point fastening of spraying equipment and hydraulic damping

Swing frame is fitted on swing frame holder in two points, which enables movement of spraying

equipment in all directions and good central position. Two-point fastening system enable better

stability and control during operation. Fastening between use and pendulum is done with

tensioners (factory set at 420 mm).

Factory damping is done through a hydraulic cylinder, which enables floating fastening of

equipment. It is fastened diagonally between parallelogram fastening and swing frame.

Cylinder response is set with choke on the cylinder, which is filled with ATF oil.

WARNING: Never remove the choke bolt, to prevent oil spill. Warranty is void in

case of modifying the hydraulic damper. Repairs can be performed only by an

authorized service.

10.7.4 Hydraulic levelling

Levelling cylinder is fastened between the swing frame holder and parallelogram fastening.

Response of levelling cylinder is set with choke. Hydraulic levelling can set balance position of

spraying equipment (horizontal position), as well as parallelism of equipment to the ground in

case of sloping terrain. Position of spraying equipment changes according to position of top part

of oscillating parallelogram.

Hydraulic levelling can greatly influence linear distribution of crop protection liquid on the

surface and quality of spraying. This makes the system very suitable on rough or sloping terrain.

Levelling cylinder response is set with chokes.

10.7.5 Hydraulic cylinders setting

Hydraulic cylinders on the spraying equipment are fitted with a choke bolt, which control

cylinder’s response.

Set it by first unscrewing the nut (2) and set the cylinder with bolt (1). Then, screw the nut

back.

All bearings are provided with greasing points for greasing eye bearings.

10.7.8 Boom opening mechanism

Mechanism for opening the first boom is done through hydraulic cylinder (figure 40), which

is fastened between the swing frame and first boom. Second and safety boom opens

simultaneously with the first boom with the help of the bar, which is fastened between the

equipment swing frame and through special lever (figure 41) between the first and the second

boom. Hydraulic cylinder is equipped with double blocking valve (2 – figure 40), which

ensures that the hydraulic cylinder keeps its position. Cylinder speed is set with choke bolt (1

– figure 40) on the cylinder. All joints are fitted with greasing points.

Figure 42: BOOM OPENING MECHANISM

For final setting of both hydraulic cylinders with booms of spraying equipment, both cylinder

have, on the fastening part, a limiting nut (pos. 1 – figure 42) with transverse safety bolts.

Limiting nut enables the cylinder to limit the position of boom closing, which is secured after

setting with counter-nut. End fitting on the hydraulic cylinder enables end position of open

equipment. When setting end fitting, first unscrew transverse bolts and then turn the piston

rod of cylinder to set desired position. Secure position by assembling transverse bolts.

10.7.9 Setting position of booms and opening bar

Parallelism and verticality of spraying equipment is set on foreseen places by

loosening/tightening the provided bolt connections and eye bearings. To ensure efficient

operation of spraying equipment, it is important that the booms are set correctly parallel.

Perform the setting on level ground, where the equipment must be open and set at convenient

height. Place a support under the lifting mechanism for safety reasons.

Boom 1:

Verticality of the first boom is set on eye bearings. Top bearing (pos. 2 – figure 43)

determines position in open position of equipment, and bottom eye bearing (pos. 3 – figure

43) determines position in closed equipment.

Boom parallelism to swing frame is set with bolt connection (pos. 1 – figure 43) on the rear

side of the boom, and with cylinder position (pos. 3 – figure 42) and position of end fitting on

cylinder (pos. 2 – figure 42).

10.8 Operation description

Equipment can be used, when the sprayer and the spraying equipment are correctly connected

to the tractor (see chapter “CONNECTING SPRAYER TO TRACTOR”). Connect hydraulic

hoses of sprayer to hydraulic connections of tractor and connect AG-TRONIK and control

panel for control of hydraulic equipment. Control of spraying equipment is performed on

level surface, when the tractor is still.

WARNING: Opening and closing of hydraulic spraying equipment should not

be performed during driving to prevent overturning or damaging the machine.

10.8.1 Opening spraying equipment

Control is performed through control levers of tractor in connection with control panel, which

ensures opening/closing of equipment and levelling (description in chapter 10.3.2). When

opening equipment from transport into working position, use lever for control of equipment

lifting/lowering to lift the equipment to top end position, and begin opening booms with lever

and correct selection of switch on the control panel. Using levelling switch on the control

panel and control lever, align spraying equipment according to the terrain, if required. Then

lower the equipment to correct height with lever for controlling lifting/lowering.

During work (driving), use lift and levelling for setting position of spraying equipment.

Other functions should be used, when the tractor is still. Use control lever and switches for

opening and closing booms to check openness of hydraulic cylinder and ensure rigidness of

equipment.

If the cylinders release, this is caused by air in the system and poor sealing of hydraulic

components.

10.8.2 Closing spraying equipment

First, lift the equipment in top position. Use hydraulic levelling to align it parallel to the

sprayer and begin closing booms. Closing of spraying equipment is performed in reverse

order as opening. At the end, release spraying equipment on mechanical safeties of sprayer,

turn off AG-TRONIK and control panel. The sprayer is ready for transport.

WARNING: When using hydraulic drawbar, always activate mechanical

blocking, before driving on public roads!

10.8.7 TRI-JET nozzle holders

Spraying equipment is, as standard, equipped with TRI-JET nozzle holders, which contain

three different nozzle mouthpieces ST 120-02, ST 120-04 and ST 120-06.

Their fixing is done with nuts of nozzle, shape and colour of which is different for different

types of nozzle mouthpieces. By rotating the lower part of the holder (clockwise, until it

locks), it is possible to easily replace the nozzle mouthpiece, required for spraying in a given

moment. Holders are also equipped with anti-dripping membrane valve for prevention of

uncontrolled dripping from nozzles.

According to different mouthpieces, there are two versions of nozzle nuts. Black nut is

suitable for mouthpieces ST, AD, LU, IDK, ID; red nut is suitable for TR mouthpieces.

11.2 Function diagram of the system

AG-TRONIK receives information, required for calculation of actual liter per hectare from:

Flow sensor, which is built in section side of regulator;

Speed sensor, which is fitted on the sprayer wheel.

Flow sensor is a component part of regulator and is connected to electric connection cabinet

on the flow regulator. Speed sensor is connected to electric connection cabinet (4-pole

connector – fig. 62).

AG-TRONIK is supplied through three-pole connector on tractor electrical circuit with 12V

voltage.

Information on condition of central regulation valve and distribution valves is recived by AG-

TRONIK through connection cable from connection electrical cabinet, mounted beside

section valves. AG-TRONIK regulates work pressure through regulation valve on the

regulator, depending on flow capacity. It ensures that flow capacity equals desired flow

capacity (hectare consumption).

11.4 AG-TRONIK keys description

Keys for turning on, AUTO, MAIN and sections have a LED diode next to the key, which

lights up or blinks, when the key is on. LEDs for AUTO and MAIN are red, key for turning

on, has a green LED diode, keys for sections have two-colour LED diodes (green and red).

Key ON/OFF – when pressing this key, AG-TRONIK turns

on. Hold the key for at least 3 seconds to turn AG-TRONIK

off.

Key AUTOMATIC – selection key for automatic or manual

control. LED lights, when automatic control is set. When

the LED blinks, automatic control is set, but the MAIN

valve is shut down due to improper spraying conditions.

Key BYPASS VALVE ON/OFF – this button opens and

closes bypass valve. Valve is on, when a red LED diode is

on above the button.

INDIVIDUAL SECTION ON/OFF keys with two-colour

LEDs – use keys to open and close individual sections.

Individual valve is on (section open), when red LED lights

above the button. If the green LED is on, the switch is on,

but not all spraying conditions are met (GPS device doesn't

»allow spraying«).

Key PRSSURE INCREASE (manual control) – the key is

intended for increasing pressure in the regulation valve. It is

active only in manual control (LED next to AUTO key is

turned off), and the bypass valve must be turned on.

Key PRESSURE DECREASE (manual control) – the key is

intended for decreasing pressure in the regulation valve. It is

active only in manual control (LED next to AUTO key is

turned off), and the bypass valve must be turned on.

Key PROGRAM – this key is used for entry in and exit

from programming module.

Key FUNCTION – this key returns AG-TRONIK to its

factory settings.

CURSORS keys – keys are intended for navigation on the

display and for setting individual values. Central key OK is

a confirmation key, with which set value is confirmed or is

used to exit the menu of quick setting.


page 62

11.5 Operation description – manual control

In the manual control spraying is provide manually. Between work we can increase and

decrease the pressure and, in this context change hectare consumption, in short, the spraying

takes place without the operation of the computer or. without automatic control.

Using the keys and opens the bypass valve

(last sectional valve), and each section, by using the buttons we regulate the

working pressure.

Closing sectional valves:

By pressing the "MAIN" button, we open the bypass valve, at the same time - automatically

closes all distribution valves (sectional valves). Above the keys to individual sections, instead

of the red LED diode, turn on green LED diode. Green LED diode indicates that the key for

sectional valves is on, but section valves are not open.

Opening the sectional valves:

For open distribution valves require the inclusion of key "MAIN", through which

automatically open the distribution valves, closes bypass valve, over the keys of the

distribution valves lights up red LED diodes, green LEDs turn off.

In so far as the AG-TRONIK entered the correct constants for the speed sensor, flow sensor

and the working width, then you can monitor across the screen all the main parameters of

spray such as:

• hectare consumption;

• speed spray

• Working width

• cultivated area treated

• hectare efficiency

• completed trail

• the current flow

• Analysis.

Manual control can be performed when the AG-TRONIK is turned on, button is

turned on (the red LED diode in the upper right corner button lights), button is off

(does not light or not flashing LED in the upper right corner of the key AUTO).

11.6 Operation description – automatic control

In automatic control, set hectare dosage is controlled by AG-TRONIK. Of course, all of the following

conditions must be met:

Correct choice of spraying parameters, such as correct choice of spraying speed, correct

choice of nozzles…;

Correct input of constants of flow and speed sensors;

Correct input of working width;

Ensure the following when spraying:

Correct choice of crop protection liquid

Correct calculation of concentration


page 63

Appropriateness of spraying according to weather conditions,

If the conditions above are met, then spraying with AG-TRONIK is very simple. The operator must

only keep driving in a steady manner, the speed being in accordance with nozzle functioning

capability (ST and LU from 1.5 bar- 5 bar; IDK from 1.5 – 6 bar and ID from 2 – 8 bar) or capability

of achieving liter per hectare with specific nozzles and timely tuning on and off the bypass valve.

Press button to turn on AG-TRONIK, bypass valve and individual sections are turned

on by pressing buttons and In automatic

control, key is turned on. Keys for manual setting of pressure DO NOT function in

automatic control.

11.6.1 Preparation for spraying

First we check if correct parameters are input in the program,

Fill the sprayer partially with water and test flow sensor functioning (when all nozzles are open –

diversion valves on the regulator, check the current flow on the display of AG-TRONIK). Sum of

flow of all working nozzles must be equal to displayed flow on AG-TRONIK,

Fill the tank with water to the top,

Go to the field or treatment location,

Fill the tank with chemical agent and turn on mixing. During preparation of chemicals, all manual

valves for mixing must be open. Ensure appropriate pressure of 2 – 5 bar,

If required, reset daily counters (ha, km, l),

Check functioning of speed measuring during drive.

11.6.2 Spraying

Before taking off, check minimum speed (chapter 9) and adjust it, if required.

Turn on section valves and move to starting point of spraying.

Check that automatic protocol is on and begin spraying.

When driving off, engage the central valve and AG-TRONIK ensures that you

achieve the set liter per hectare in the least time possible. If the minimum speed is

adjusted properly, AG-TRONIK ensures automatic opening and closing of the main valve on the

regulator. At the end of the line, when you reduce driving speed under minimum set speed, it

automatically closes central (MAIN) valve and reopens it when spraying speed exceeds minimum set

speed.

In bypass regulation, MAIN valve functions as follows:

When the MAIN valve button is turned off, all sections, which were open, automatically close. Green

LED turns on above these sections instead of red LED.

When the MAIN valve button is turned on, the bypass valve closes, and all distribution valves, which

had the distribution valve button turned on (green LED above button), automatically open.

Buttons for distribution valves are independent of MAIN valve and can be opened or closed, when the

MAIN valve button is off. Valves open in connection with MAIN valve and open and close in relation

to position of MAIN valve button.

11.6.3 After spraying

After spraying, make sure that all vital parts of the regulator are adequately washed with clean water

as soon as possible! It is best to direct a flow of clean water for some time through the pressure

regulator.

not display symbol for GPS device (chapter DISPLAY DESCRIPTION).

If you have selected manual or automatic protocol, basic display shows symbol for GPS

device . If the symbol is flashing, this means that GPS device is selected, but there is


page 68

no suitable cable connection between AG-TRONIK and GPS device or the GPS device is not

functioning properly or there are not enough satellite signals for operation.

If the symbol is not flashing, connection between AG-TRONIK and GPS device

functions perfectly and devices communicate with each other.

Meaning of MANUAL, AUTO:

If the connection between AG-TRONIK and GPS device is in MANUAL protocol, this means

that sprayer operation can be automatic or manual, and GPS device only records work.

If the connection between AG-TRONIK and GPS device is in AUTO protocol, this means

that GPS device is in control of automatic operation of AG-TRONIK.

11.7.5 Flow constant

Flow constant is the number of impulses (imp/l), which the flow sensor gives to AG-

TRONIK, when 1 liter of fluid flows through it. The constant changes, when the density of

the fluid (chemical) changes or by substantial change of flow through the sensor. Sensors are

factory set to nominal flow and the value is entered on the flow sensor. The constant must be

checked and corrected occasionally. How a new constant is measured and entered is described

in different sub-chapters: NEW CONSTANT, KNOWN FLOW and CORRECTION. Known

flow means that the constant is known and just needs to be entered. Known flow and

correction are measurements. Here, constants are measured and entered. According to length

of measurement or precision, the KNOWN FLOW is differentiated from CORRECTION.

With known flow, the measurement lasts 30 seconds, with CORRECTION, the time of

measurement is the time of emptying one tank.

To enter window »FLOW CONSTANT«, select icon and confirm it with

confirmation button The display shows:

This window offer three options:

New constant,

Known flow,

Correction;

With key and move the selection window and choose the way of changing flow

constant.

Press key to open a separate window.


page 69

New constant:

If you know the flow constant or it is shown on the flow sensor, then choose the new constant

menu. Choose the line NEW CONSTANT and press key to open the following window:

If you wish to enter a change of value, press key . The value starts to blink. Set new

value with keys and and confirm it with key . New value is shown.

Use button to return to basic image of menu "FLOW CONSTANT".

Known flow:

Is used, if the constant is unknown or if flow through flow sensor changed significantly

(replace nozzle inserts with greater or smaller flow). In this case, measure flow capacity of

nozzles at defined pressure. Perform the measurement in the following manner:

Select manual protocol on AG-TRONIK, open all distribution valves and bypass valve.

Note: known flow functions only in manual protocol. If the AUTO protocol is on, entry in

window is not possible, X blinks next to the display.

Set pressure to value, set for spraying, e.g. 3 bar. Use gauged flask to measure flow of one

nozzle in one minute. If the nozzles are new, capacity or flow/nozzle can be taken from

enclosed factory flow table. If the measured flow (or recapitulated flow from table) per nozzle

is multiplied by the number of functioning nozzles, we get KNOWN FLOW or total current

flow through flow sensor. It is important that the water flow through sensor during

measurement is similar to liquid flow in the time of spraying.

ATTENTION! Flow sensor functions correctly only in the range from 10 to 100 l/min.

Choose the line KNOWN FLOW and press the key to open new window:

The display shows:

Current constant [imp/l]

Number of operating nozzles [no.nozles]

Flow/nozzle [flow/n]

Common flow through nozzles [flow]


page 70

Option of entering following parameters is available:

Number of operating nozzles [no.nozzles]

Flow/nozzle [flow/n]

Common flow through nozzles [flow]

When you open the window KNOWN FLOW, the value in number of nozzles is framed. If

you wish to change the number of nozzles, press key to choose the line (frame starts

to blink). Set new value with keys and and confirm it with key .

If you wish to change the value in the line flow/nozzle, follow this procedure:

Press key to move the frame to the value of parameter flow/nozzle. Press key

and the value start to blink. Set new value with keys and . Press key again

and the display changes the value of common flow (in our case the value is set to

45,001) and in the lower left corner –MEASUREMENT- is displayed. The display disappears

after 30 seconds, and the display shows new value in the line imp/l (in our case – 100).

.

Note: during entering or measurement in the window KNOWN FLOW, flow through nozzles

must be the same as with measurement with gauged flask!

Entering common flow through nozzles is done in the same manner as entering flow/nozzle.


Control “KNOWN FLOW” can be done also during spraying to perform a more precise

measurement by regarding viscosity of the chemical.


page 71

Correction:

Constant correction of flow sensor is the most accurate measurement. It is done, when the first

tank has been sprayed. The positive side of correction is that a measurement with chemical is

performed, therefore correct density of chemical is regarded, and the down side is that it can

only be executed, when the first tank is emptied.

Measurement starts before the start of spraying. At that time, daily counter of spray

consumption must be set to "0" (chapter PROGRAMMING, Erasing daily counters of spray

consumption [l], surface area [ha] and path [km]). Spraying follows. When complete (known)

capacity of chemical substance has been used, e.g. 400 l, and value 393 l is displayed on basic

readout under section l, correction must be performed. Follow the procedure below to perform

correction:

Select line CORRECTION and press key to open the following window::

Following quantities are displayed:

current constant imp/l (711)

measured quantity (393)

actual quantity (393)

Actual quantity is selected and when you press key , it starts to blink. Set measured

quantity with keys and . Once the quantity is set, press key to display new

constant imp/l (698 imp/l).



page 72

11.7.6 Speed constant

Speed constant is the number of impulses (imp/km), which the speed sensor forwards to AG-

TRONIK at a distance of 1 km. It depends on the circumference or diameter of wheel and

number of marks on the wheels. Number of impulses is partly affected by tyre pressure and

wheel draught (wet/dry ground).

How the constant is measured and entered is described in different sub-chapters: NEW

CONSTANT, PARAMETERS r,N and DISTANCE.

To enter window "SPEED CONSTANT", select icon and use confirmation button

to confirm it. The display shows:

Window offers three options:

With key and move the symbol √ and choose the way of changing speed constant.

Press key to open a separate window.

New constant:

If wheel diameter (d), which carries the speed sensor, is given and if the number N of metal

parts (marks), which cause signal on sensor, is given, then the number of impulses per

kilometre can be calculated according to the following equation:

𝑖𝑚𝑝.𝑘𝑚⁄ =

𝑁×500

𝑟×𝜋

Example:

r = 0,75 m

N = 4

𝑖𝑚𝑝.

Minimum spraying speed with bypass regulation: In bypass regulation, the "MAIN" valve functions as follows:

When the "MAIN" valve button is turned off, bypass valve opens, and all sections, which were open,

automatically close. Green LED turns on above these sections instead of red LED.

When the "MAIN" valve button is turned on, bypass valve closes, and all distribution valves, which

had the distribution valve button turned on (green LED above button), automatically open.

Distribution valve buttons are independent of "MAIN" valve and can be opened and closed when the

MAIN valve button is off. Valves function in connection with "MAIN" valve and open and close in

relation to position of "MAIN" valve button.

Simulation:

Simulation is primarily intended for presentation and training or explaining functioning of

AG-TRONIK. Simulation is activated by changing value to ON, and deactivated by changing

value to OFF or turning off AG-TRONIK. When simulation is activated, letter S flashes in the

basic menu.

Simulation symbol ON

Press or hold button and to change speed, and change pressure with buttons

and . Pressure can be changed only in manual protocol. Automatic protocol is possible,

when flow is greater than 8 l/min. Simulation enables simulation of spraying, opening valves,

regulating pressure...

Flow measuring protocol:

AG-TRONIK enables two ways of measuring flow, namely with:

flow gauge

pressure gauge

Regulation is basically performed with flow gauge. In this way, you enter flow constant in

program (Chapter “FLOW CONSTANT”), and AG-TRONIK regulates flow or pressure on

the basis of received impulses from flow gauge.

Pressure regulation is an option, where an additional pressure sensor is installed on pressure

regulator or pressure line. Pressure sensor helps with measuring pressure. Flow capacity is

calculated by AG-TRONIK from installed algorithms for individual nozzle insert. If a

PRESSURE DISPLAY

FLOW MEASURING PROTOCOL

DISPLAY


page 78

pressure sensor is installed, pressure is displayed on basic image. Pressure is displayed

independent of selected flow measuring protocol.

Enter pressure protocol in subprogram general settings, where you position selection frame in

line REG MODEL. As default, FLOW is selected (measuring with flow sensor). Press button

and selection frame starts flashing. Use button to change display in PRESSURE

(measuring with pressure sensor) and press button . In lower right corner of basic menu,

PRESSURE is displayed and icon of flow constant no longer shown. There is empty position,

where the icon should be. This activates flow measuring with pressure gauge.

After setting protocol, nozzle type must also be set in pressure protocol. ISO colour and size

scale is used for marking nozzles. If the installed nozzles are manufactured by nozzle

manufacturer, which does not use ISO standard for marking nozzles, use tables to select

nearest nozzle according to ISO system, and provide suitable correction factor.

After selecting nozzles, correction must be entered. You can select correction factor from 0.9

to 2. If the nozzles are new and marked according to ISO system, you can enter correction

factor 1. This means that the nozzles function with flow, given in the table (applicable for ISO

marking). Otherwise, flow measurement at individual pressure must be performed. Perform

the measurement in the area, where spraying will be done. Use gauge flask to measure flow

and compare it to table. If the flow is greater than flow from the table, correction factor is

greater than and is calculated by dividing value of measured flow with value of flow from the

table.

Note: if you have selected flow measuring protocol with pressure, and do not have appropriate

equipment installed (pressure sensor), then AG-tronik will not function in automatic protocol,

analyses will not work and information regarding flow measuring will not be displayed in

individual menus.

In manual protocol, values regarding flow will not be displayed. It is similar in protocol with

flow gauge selected, but the equipment does not have flow gauge installed.

Manufacturer Lechler uses ISO system for marking nozzles.

state of open nozzles, flow per nozzle and total flow:

If you change spraying parameters, e.g. speed, values of flow/nozzle and total flow change. If

you reduce or increase working width and confirm it with confirmation button , number

of functioning nozzles changes accordingly.

11.8.3 Work

Window WORK enables:

start/continue

pause/end

rename lot

erase lot

It is recommend to include analysis, when you start work or during the preparation of the

sprayer for spraying. Turn off analysis, when you end spraying. If you are continuing work

the next day on the same lot, simply press key continue and continue work on the same lot.

Lot or work with the same name can be used many times, but generally each lot should have

its own name.

If you have assigned name LOT1 to one lot, you can save all analyses, which you have made

on lot LOT1, and collect and analyse them later on in overview and on printouts on the

computer. This enables overview of all spraying activities, which were executed in the period

of e.g. one season, but the time period can of course be longer.

If you have aborted work on one lot for several days and sprayed on other lots in the

meantime, you simply select new work and write the same lot name, e.g. LOT1, under the

name of new work. When you look at the analysis printout, the logic of analysis and printout

becomes simple.

11.9 Printouts

11.9.1 Inserting SD card

AG-TRONIK writes analyses to SD memory card, which you received upon purchase of

automatic regulation. Writing to SD memory card is described in detail in the chapter 10

"ANALYSES", subchapter10.3 "WORK". On the left side of AG-TRONIK, where supply

cable is plugged in, there are two rubber covers. Under the top cover are fuses, and under the

bottom cover is a slot for SD memory card and connector for programming AG-TRONIK

(figure 84). If memory card is not inserted in the slot, insert it so that the front of the card

faces the front of AG-TRONIK. Insert the card all the way and release it. Remove SD card by

pushing the card all the way and releasing it. Then, pull the card out of the slot.


page 91

11.9.2 Data transfer to computer

When analyses are written on the card, they can be viewed on a personal computer. You need

a SD card reader, if you do not have an appropriate SD card slot on your computer. Content

on SD card is read by the computer automatically.

File format is TXT type and can be viewed in programs Notepad, Word, Excel and in

programs, which read TXT files.

Notepad printout:

When opening a file in Notepad, the file appears as following form:

BEGIN marks the start/continue of

specific ANALYSIS, and END marks

cancel/end of ANALYSIS. Each cancel

makes a new start and end of specific

ANALYSIS.

Printouts are prepared so that they are all

gathered under one lot. If you have

selected lot name JANEZ1, then all

analyses, which have been written under

JANEZ1, are gathered in one file, in our

case file JANEZ1. Analyses are sorted in

descending order according to date and

time. If you have chosen new nozzles,

such as in case of lot JANEZ1 (ID nozzles

were replaced with nozzles ST/LU), and

you have done this with “cancel work”,

two .TXT files appear, as in the example

on the left.


page 92

Excel printout:

Excel printout is a better option. Here you can add up specific fields or edit them in

another manner. When transferring, be careful to transfer data to Excel correctly. First,

open program Excel and find the file, where analyses are written and confirm it. If the list

does not show files, select All files and they appear.

When transferring, pay attention to transfer mode. First, window opens, where you choose

fixed width of field; then continue to the next window. In this window, you define field

widths and can be skipped.

In third step, you must determine type of data reading. Because data includes dots,

commas and colons, it is likely that date or time will be shown instead of real data of ha.

In this step, you must select third column, and choose text for data format (selection list,

above right).


page 93

Deleting files form SD card:

If the number of files on the card is too great or the card is full, old files or files that are no

longer useful must be deleted. Insert SD card in the reader and connect it to personal

computer. Open window, where all files are shown and delete unnecessary files from the SD

memory card.

11.10 GPS output

On the right side of AG-TRONIK are two connectors for connection of GPS device. Top GPS

output is intended for connection with GPS device of simpler type, where GPS device records

and maps sprayed surface on the basis of main valve being open. Bottom (8-pole) connector is

intended for connection of GPS device, with which you can control the sprayer precisely to

section. Before purchasing GPS device, consult with authorized dealer for Agromehanika, if

the GPS device is compatible with AG-TRONIK.

11.10.1 GPS output 12V

If GPS navigation device enables connection of external signal, which control operation of

"BYPASS" valve on spraying device, the connection makes work a lot easier with the GPS

navigation device. This means that you do not have manually turn button for spraying device

on the GPS navigation device on or off, but AG-TRONIK sends data on "BYPASS" valve

being open.

Output is single pole (12V=). With AG-TRONIK, you also received male connector, which is

used for eventual connection.


page 94

11.10.2 GPS serial communication

GPS device, which can control individual sections of spraying equipment, is connected to

bottom connector. When connecting, be careful to correctly plug in male connector of GPS

device in AG-TRONIK. Turn on AG-TRONIK and when it displays basic image, turn on

GPS device. When starting, GPS device "reads" important settings from AG-TRONIK, such

as working width of individual sections, hectare consumption... There are three options of

connection protocol of GPS device and AG-TRONIK (OFF, MANUAL, AUTO). Setting of

GPS device operation protocol is described in chapter “PROGRAMMING”, subchapter “GPS

device type setting”.

OFF protocol:

If you do not wish to use GPS device in connection with AG-TRONIK, select OFF protocol

in AG-TRONIK. Use this protocol also if you have a GPS device, which is not compatible

with AG-TRONIK.

MANUAL protocol:

Use this protocol, if you want to control the sprayer yourself, but you want GPS device to

record and map sprayed surface. In this case, GPS device is naturally very helpful, as it

graphically displays sprayed surface, proposes driving direction, accurately maps direction

and position of spraying devices, proposes start of turns to reach correct line (spraying path)...

AUTO protocol:

In AUTO protocol, control and operation of AG-TRONIK is performed by GPS device. GPS

device in AUTO protocol performs control of individual sections of spraying device. It opens

and closes individual sections of spraying device according to spraying requirement. It

basically ensures that sections are open on unsprayed surface and that individual sections are

closed on already sprayed surface. In GPS device, set "overlapping" (0-100 %) and spraying

protocol at lot edge.

The operator can still manually control the spraying device, namely open and close individual

sections, regulate hectare consumption, adjust driving speed, select nozzles... Section valve

buttons are fitted with two-colour LED diodes, red and green:

If the red diode is on above individual section, this means that spraying is taking placing and

that there are no restrictions.

GPS SERIAL COMMUNICATION

GPS OUTPUT 12V


page 95

If the green diode is on, this means that GPS device allows spraying and the operator of

spraying device has manually turned off an individual section. Operation of spraying device

is, in addition to LED diodes, also shown graphically on display.

If LED diode is on, it means that the section is closed and that it is on a part of already

sprayed surface.

Serial communication ensures mutual communication and exchange of data between devices:

- speed

- open status of section valves

- open status of main valve

- sprayed [ha]

- hectare dose

- path

This data is important for correct regulation and operation of sprayer. E.g. AG-TRONIK

receives speed from GPS devices, as it is much more accurate, because it does not include

sliding, sinking, speed in turns..., data on hectare dose, which is important for analysis of

work, if work is received from GPS device.


page 96

12 PRESSURE REGULATOR

Pressure regulator with bypass regulation is by far the most suitable for trailed sprayers,

because of better response time of distribution valves when spraying.

Bypass regulation has its regulation part separated from distribution valves. Regulation part is

located closer to the pump, suction and pressure collector, while the distribution valve is

located closer to the nozzle, so the response time of the distribution valve can be better/ is as

big as it can be.

Besides the separation of regulation and distribution valve, “main” valve was also canceled.

This function has taken the bypass valve. The function of the bypass valve in this system is

the opposite of the “main” valve. When you want to change the current, you open the bypass

valve, at the same time, all the distribution valves close (in manual or in automatic mode).

With this we accomplish a constant circulation of the crop protection liquid through the whole

system and with that we prevent sedimentation of crop protection liquid in the pressure

regulator.

12.1 Pressure regulator parts

Pressure regulation in bypass version is composed of two parts:

1- Regulation valve with filter

2- Section valves EC-06

Figure 57 REGULATION VALVE WITH FILTER

Figure 58 SECTION VALVES EC-06


page 97

LEGEND:

1. Regulation valve

2. Pressure gauge

3. Self-cleaning pressure filter

4. Section valve

5. Flow meter

6. Bypass valve

Regulation valve with filter is normally installed in the front part of spraying device, close to

pump and optional 5-way pressure valve. Set of distribution valves is installed on spraying

equipment, as close as possible to nozzles.

12.2 Designation of the regulator

Example: designation PR 3ECFM /7EC+2

Basic designation of the regulator is PR-3EC. Basic designation also has designation F, which

means that the regulator is fitted with self-cleaning filter; M means that the regulator is fitted

with flow meter; designation 7EC represents 7 electromotor diversion-regulation valves, and

the last number 2 means that the regulator is fitted with two manual diversion valves. The set

also includes speedometer and belonging speedometer holder.

In bypass version, the regulation valve with filter has no particular designation in title. In the

set of distribution valves, designation EC-06 means total number of valves, including bypass

valve. Designation 06 means 5 section valves and one bypass valve.

12.3 Description of main component parts of the regulator

12.3.1 Regulation valve with filter

Regulation valve with filter set

is composed of three parts:

1. Regulation valve

2. Pressure gauge

3. Self-cleaning pressure

filter

The set ensures correct

spraying pressure and filtration

of chemicals on the spraying

device.

- Regulation valve type 463 –

grey, regulates pressure from

0-20 bar, flow volume is 190

l/min, and time required for

regulation from 0-20 is 7 s.

- Self-cleaning pressure filter

326 filters chemicals before

entering the nozzles. Particles,

which remain on filter insert

with density M 80, return to


page 98

tank through valve on the bottom of the filter (red wheel). By turning the wheel in counter-

clockwise direction, you open the flow through filter valve.

Valve is closed during spraying. If you want to clean the filter, open the valve and create flow

through pressure filter in the tank. Repeat this every time when filling the tank with clean

water. From time to time, unscrew filter cover (turn in counter-clockwise direction) and

mechanically clean filter insert. If you are using powder agents, perform this operation more

frequently.

12.3.2 Section (distribution) valves EC-06

Set of section valves EC consists of:

Legend:

1. Section valve

2. Flow meter

3. Bypass valve

4. Connection for pressure gauge or pressure switch

The purpose of section valves is supply of chemicals to individual sections on spraying

equipment. The last valve is the bypass valve, which functions as MAIN valve. Description of

bypass valve operation is provided in chapter 11.5 for manual spraying protocol and in

chapter 11.6 for automatic spraying protocol. Distribution valves can control pressure up to 20

bar, and flow capacity depends on the size of output adapter. Size of output adapter for

section valves is 13 mm; bypass valve has a 19 mm output adapter. Return line from bypass

valve is connected to suction line collector. Flow sensor is a part of distribution valves set and

is described in detail in chapter below. Bypass valve also has a connection R 1/4" for pressure

gauge connection for service or pressure switch for measuring pressure or flow (flow

regulation) with pressure switch.


page 99

Figure 59 FLOW METER

12.3.3 Flow meter

Flow sensor forwards impulses of flow gauge to

AG-TRONIK. Connections are of size R 11/4".

Measuring range is 10-100 l/min. Flow gauge cable

is connected to electrical connection cabinet. On

the gauge is a card with written flow constant. You

can also measure flow constant. It is recommended

to measure flow constant for chemical substances,

density of which greatly differs from density of

water. Measurement or determining flow constant

is described in chapter “FLOW CONSTANT”.

As standard, POLMAC flow gauge is installed.

Flow measuring is performed by a turbine, which

is installed in flow gauge housing. Gauge turbine is

sensitive to spray residues, which remain in flow

gauge after spraying. Therefore, make sure that the

flow gauge is cleaned internally with clean water

after each spraying.

.

If there are greater deviations of flow constant

from planned value, the cause can be incorrect

operation of flow sensor. In this case, thoroughly

clean the sensor, especially in the sensor turbine

area. Before cleaning, make sure that there is no

water or chemical substance inside the regulator.

Unscrew flow sensor nut and use air or running

water to clean sensor turbine. When you finished

cleaning, replace the sensor to original position.

Instead of flow gauge with turbine, electromagnetic flow gauge can be installed, which has no

rotating parts inside the flow gauge and is therefore not sensitive to dirt and sand. Using

electromagnetic flow gauge is recommended on areas, where there is a lot of fine sand in

clean water, which is used for spraying. The downside of the gauge is change of flow

constant, when using copper accessories or accessories with different conductivity than water.

Such accessories require calibration of flow gauge. Connection of electromagnetic gauge to

electrical cabinet is different than standard connection. Before installing such gauge in

pressure regulator, consult technical staff of Agromehanika.


page 100

Figure 62 SPEED SENSOR

12.3.4 Pressure sensor - option

Instead of measuring flow with flow gauge, flow

can be indirectly measured with pressure sensor.

Pressure sensor is installed in pressure gauge

position. Measuring and readout of pressure are

shown on basic image of display of AG-TRONIK.

Pressure sensor indirectly measure flow according

to nozzle flow. Measuring flow with pressure

sensor is described in detail chapter “GENERAL

SETTING, Flow measuring protocol”.

12.3.5 Pressure gauge

Figure 61 PRESSURE GAUGE

As standard, pressure regulator is fitted with

pressure gauge with diameter of 100 mm,

class 1.6., double stage, where first stage is in

area 0-8 bar, coloured green, and second

stage in area 8-20 bar, coloured yellow or

red. Pressure gauge is filled with glycerine,

which stabilizes the indicator. During winter

time, it is recommended to unscrew pressure

gauge and store it in a warm place, if the

sprayer is exposed to temperatures below

freezing point.

12.3.6 Speed sensor

Speed measurement, if performed through induction no-

contact sensor. On driven sprayers, the sensor is installed on

rear right wheel axle (figure 114). On carried sprayers, it is

installed on tractor housing and measures passages of wheel

nuts. Type of no-contact sensor for AG-TRONIK 14 is code

NPN: 917006-05.

Distance of sensor from mark is

also important, which should be

between 3 and 5 mm.

Figure 60 PRESSURE SENSOR


page 101

If the tractor has an output signal for measuring speed, signal from the tractor is used instead

of no-contact sensor. In this case, the tractor connector is connected to AG-TRONIK 14.

Required connection cable code: 018.60.530. Speed constant for input in AG-TRONIK 14 is

1024.

NOTE: speed constant applies to standard tractor wheels. If you have changed

wheel type, a new constant must be entered. (chapter »PROGRAMMING«;

subchapter »SPEED CONSTANT«).

Appearance of connection connector for speed

gauge. The connector is standardized and is the same

for all tractor.

12.3.7 Electrical connection cabinet

All sensors and motors are connected in electrical connection cabinet, where processor part of

AG-TRONIK is also fitted. On command cabinet of AG-TRONIK are display, buttons and

circuit, required for communication with electrical connection cabinet. Connection AG-

TRONIK – electrical connection cabinet is made with connection cable and serial

communication mod-bus. Cabinet, in addition to processor part, also includes power part with

automatic fuses, relays, connection clamps... Engine protection is provided for by automatic

fuses. In case of short-term overload, fuse disengages and reengages in the next moment. If

there is a serious motor fault and the fuse does not engage, fault must be remedied by

authorized service of Agromehanika.

Speed sensor is connected to bottom part of connection cabinet (4-pole connector). Flow

sensor is connected to connection cabinet through connection clamps.

Figure 63 ELECTRICAL CONNECTION CABINET


page 102

12.4 Regulator maintenance

1. After each spraying, the regulator must be thoroughly washed with clean water,

because only this helps to keep the regulator in good condition, operation errors are

fewer, which reduces the costs of service.

2. Occasionally clean the external part of the regulator and grease rotating and sliding

parts. Most appropriate agent is WD-40 or similar maintenance agents.

3. During winter, all water must be emptied out of the regulator, the valves must be

left open or keep the regulator in a warm place. If you fill the sprayer during winter

with antifreeze or agent against freezing of windows, open valves and buttons on

valves to prevent freezing in dead, inaccessible places of the regulator.

4. It is obligatory to unscrew the pressure gauge and keep it in a warm place.

12.5 Parameters setting in AG-TRONIK program

Technicians of Agromehanika input parameters, required for spraying in AG-TRONIK and

save these parameters in factory setting. AG-TRONIK is accompanied with a sheet of

parameters – settings, input as factory settings.

If the speed sensor is installed subsequently or you have installed a speed sensor on tractor

wheel, then the parameter of speed constant is unknown and has to be input manually. See

chapter PROGRAMMING, SPEED CONSTANT, for help.

If you are connecting a non-standard

flow gauge to AG-TRONIK, consult

technical staff of Agromehanika.

13 MAINTENANCE

13.1 Sprayer cleaning

After each use, the sprayer must be thoroughly cleaned. The best way to use any excess

insecticide is to dilute it with water and spray it on the same surface again. The concentration

should be at least 10% (10 units of water per one unit of insecticide), the spraying speed

slightly faster and the spraying pressure slightly lower (1.5 bar, depending on the nozzle).

While doing this, use the additional tank for washing. The procedure is described in the

chapter “COMPLETE CLEANING OF THE SPRAYER”. After that, thoroughly clean the

sprayer on the inside and the outside and also clean all tolls which you have used for spraying

(including the tractor). Use only detergents that are recommended by the manufacturer of

protection agents! If there are instructions for cleaning of the device after using it attached to

the instructions for using the insecticide, follow them.

In accordance with local legislation regarding pesticide discharge into ground, arrange sprayer

cleaning with you counselling service.

Washing of pesticides (cleaning of the sprayer) must not be performed on swampy ground or

in the near of streams, water dams, dykes or water fountains, etc.

If there is still some insecticide inside the sprayer and if you had to stop working

unexpectedly for some time it is recommended to clean the pump, the regulator and the

spraying lining with clean water (see chapter “PARTIAL CLEANING OF THE SPRAYER”).

WARNING: In case you had to stop working unexpectedly but did not clean the

sprayer yet, you have to assure that other people or animals cannot reach the

sprayer.

NOTE:

- Only a clean sprayer is a safe device

- A clean sprayer is ready to be used

- A clean sprayer cannot get damaged by chemical agents or chemical solvents

When cleaning the sprayer use appropriate protection clothes. Choose appropriate detergents

for cleaning and, if necessary, appropriate insecticide neutralising agents (see

recommendations of the insecticide manufacturer).

If using detergents (mixture of water and detergent), pour it in the main tank (distribution

valves for nozzle distribution are closed), turn on the pump, open distribution valve for

mixing, valve of self-cleaning filter and, after a few minutes, open distribution valves for

nozzle distribution. Be careful, where you discharge the cleaning agent. Some detergents take

time to become effective, which extends the cleaning process (see manufacturer’s

instructions).

WARNING: Be careful when handling detergents!

Follow the detergent manufacturer’s instructions!


page 105

After cleaning the sprayer with a detergent, fill at least 1/5 of the tank with clean water and

repeat the cleaning process. Make sure that you have cleaned all elements that have come in

contact with the insecticide or the detergent.

Thoroughly clean all filters and be careful not to damage the filter insert. If the filter insert is

damaged, replace it. Filter cleaning procedure is described in chapter “SUCTION FILTER”.

Clean the nozzles at the end. Clean nozzles only with a soft brush, compressed air or water.

Cleaning with hard objects can damage the nozzles.

WARNING: If you clean the sprayer with high-pressure cleaning device, we

recommend greasing of all moving parts after cleaning!

13.2 Maintenance and storage after season

When the spraying season is over, find some time and prepare the spraying device for storage.

Before storing the device, thoroughly clean the inside and the outside of the sprayer

(regulator, pump, sieves, selection valves, nozzles, etc.). When the cleaning is done make sure

that there is no water left in the valves, the filters, the pump, the nozzles, etc. Do not maintain

the sprayer until it has not been thoroughly cleaned.

13.2.1 Hoses

Check tightness of all hoses and hose junctions. Replace damaged hoses with new ones. A

damaged hose can cost you a lot of time during spraying.

13.2.2 Paint

Some insecticides contain solvents which affect the paint. Clean the corrosion off of

colourless parts of the spraying device and apply some new paint.

13.2.3 Tank

Make sure that there are no rests of insecticide inside the tank. Chemical agents must not stay

in the tank for a long time, since they can fast shorten the durability of the tank and other

parts. Make sure that the outflow is opened.

13.2.4 Pressure regulator

Protect the pressure regulator against moisture and dust. Use a plastic bag. We recommend

lubricating moving parts with WD-40 or oil.

13.2.5 Hose connections

Causes of poor sealing of hose connections:

- missing seals

- damaged or poorly inserted seal

- dry or deformed seal

- incorrect connections


page 106

Therefore, in case of poor sealing or leaking:

- DO NOT TIGHTEN the joint too hard, since you can easily damage it. Take the joint

apart and check the condition and position of the sealing or the O-ring, clean and grease it

and reassemble the joint.

- Use only non-mineral lubricant (bio-lubricants) for lubrication.

NOTE:

- Radial sealing – manual tightening of fitting is adequate.

- Axial sealing – apply small force with hand tool.

13.2.6 Drive shaft – cardan

It is important that the safety pin, which is attached to the head of the cardan shaft, is clean

and greased. This assures that the shaft is safe to use.

Check the protective cover, the functioning and the condition of the cardan shaft every 40

working hours. Replace damaged parts with new ones.

Check the protective cover of the cardan shaft every 100 working hours and, if necessary,

replace the sliding plates of the protection. Also check the condition of the cardan shaft. Pay

special attention to the safety pin. Replace damaged parts with new ones.

13.2.7 Bolts

IMPORTANT: Check bolts, pins and especially safety pins, their tightness and their

condition. If necessary, tighten or replace them. The information on the necessary bolt

tightness can be found in the table bolt tightening torque (chapter 13.3).

13.2.8 Pump

After spraying season, thoroughly clean the inside and the outside of the pump and prepare it

for storage. Check the quantity of working hours and, if necessary, repair the pump (oil

change, diaphragm change, sealing change, etc.) or at least check the oil level, the sealing, etc.

This is the most appropriate time of the season to perform some maintenance work. If you are

not sure whether or not you can repair the pump on your own, leave the work to an authorized

expert. Description of maintenance tasks is provided in chapter “PUMPS”.

13.2.9 Other parts

The rest of the vital parts such as filter inserts, pouring sieve, additional equipment, etc. must

be thoroughly cleaned, checked and replaced if necessary, too. Remove the remaining water

and eventual sediments from parts such as suction filters and three-way valves. Grease all

moving and sliding parts of the sprayer.

WARNING: If the temperatures go below zero, protect the spraying device against

cold to prevent damage!


page 107

This requires:

- either removing water from the pump, the regulator, the hoses, the filters and other

elements…;

- either storing the device in a warm space;

- or using an agent against freezing (antifreeze).

13.2.10 Procedure of protecting the sprayer with anti-freezing agent

After you have finished cleaning the spraying device, completely empty the tank and pour at

least 10 litres of antifreeze agent (a mixture of water and antifreeze) and turn on the pump.

Open all valves on the regulator in order the antifreeze agent can reach all hoses and nozzles.

At the end, empty the remaining agent from the tank in a suitable container and let the pump

operate for few more minutes in order to pump the remaining agent into the tank.

WARNING: Make sure that the antifreeze agent is poured into appropriate

containers! Do not discard antifreeze agents in nature!

Protect the manometer against freezing by unscrewing it from the regulator and storing it in a

warm room. The manometer must be stored in an upright position or the glycerine filling can

flow out!

14.4 Removing the sprayer

Once the spraying device cannot be used anymore, you will have to clean it completely, take

it apart and sort the individual components of the sprayer by material. The components must

be handed over to an organisation which deals with waste materials. The reservoir and other

plastic parts of the sprayer can be recycled or burned in special incineration sites. The metal

parts can be sorted out as scrap metal. Consider the local legislation for waste materials.

14.5 Connection for control pressure measurement

Connection for control manometer has thread R ¼” and is on the rear side of the sprayer, on

regulation valves EC-06, as defined in chapter 12.3.2.

For connection, unscrew thread plug (cat. nr. E 15783) and screw a control manometer in its

place.

14.6 Control measurement of nozzle flow

For nozzle flow measurement, a piece of soft flexible plastic or rubber hose is required, with

internal diameter 25 mm or 1″ and a suitable catching container (gauge glass is

recommended). Simply attach the hose to the nozzle and measure flow quantity of individual

nozzle with catching liquid in the container. To measure flow quantity, you need a stopwatch

or a watch. Time of measuring is one minute or if you have measured for a shorter amount of

time, recalculate measured flow quantity to one minute.

If the measured flow quantity of nozzle at certain pressure exceeds table value for more than

10 %, the nozzle insert is worn out and must be replaced.

14.7 Connection for control measurement of pump flow

Pump flow gauge can be connected to return line of flow regulator. Remove fitting for hose

ϕ25 (see catalogue drawing), and install a fitting in its place, which is connected through flow

gauge in the tank. The sprayer comes with fitting with suitable seal.

15 GENERAL INSTRUCTIONS FOR SPRAYING

For a successful spraying, the appropriate water quantity, right nozzle selection and a precise

consumption calculation are of major impotence. It is recommended to stick to the following

order when it comes to preparing of the spraying mixture and spraying:

Make sure that the spraying appliance is in flawless condition. Check the oil level of the

pump and clean all filters.

Read the instructions which are attached to the protective agent. Pay special attention to

the prescribed concentration, the dose for a hectare and the recommended water

consumption.

Choose an appropriate tractor speed and – if you do not have a reliable value – measure

it. It is very important to have precise speed values when it comes calculating the

quantity of the mixture.

Choose appropriate nozzle type and size according to the crop and required water

consumption. Use the nozzle tables.

Fill the reservoir with half of the fresh water you will need.

Adjust the working pressure on the regulator and check the liquid flow rate through the

nozzles.

Calculate the required water consumption per hectare according to the measured liquid

flow rate through the nozzles and the working speed.

Fill the reservoir with the mixture and add the required water quantity.

While working, pay attention to a constant working speed, the height of the spraying

equipment, the working pressure and nozzle operation.

Clean the sprayer after you finish working.

WARNING: Sprayer is NOT SUITABLE FOR USE LIQUID FERTILIZER!

In case of emergency use, we recommend consultation with our technical service!

15.1 Nozzle types in farming

15.1.1 Nozzle types with a flat jet

This kind of nozzles is principally used for spraying with

herbicides, insecticides and fungicides. The insecticide is

precisely distributed along the whole working range of the

nozzle. At lower pressure, the drops are bigger and less

sensitive to wind and vice-versa. The recommended

working height is 0.5 meter above the crop.

For reasons of correct overlapping of the jets, the nozzle adjustment is very important. The

nozzles must be offset for 5°-10°according to the equipment.

15.1.2 Whirl nozzles

Recommended working pressure:

Herbicides: 1.5-3 bar

Fungicides: 3 -5 bar

Insecticides: 3 -5 bar

The jet of such nozzles in formed like a rotating cone. They consist of a

whirling and a spraying part.

The main characteristic of these nozzles are smaller drops, the

insecticide distribution is worse. They are suitable for spraying with

fungicides and insecticides.

Recommended working pressure: 2 - 10 bar

Recommended working height: 0.5 meter.


page 114

15.2 Wind influence

If possible, avoid spraying in windy conditions. If this is not possible, remember the

following:

- use special nozzles (“Anti drift”, injection nozzles, etc.)

- use nozzles with larger flow rates

- lower the pressure during spraying

- use nozzles which spray bigger drops (400 μm)

- reduce the working speed

- spray in the direction of the wind.

15.3 Water consumption during spraying

Adjust the water consumption to the growth of the crop and the way the protection agent is

working which you will be using. Normally, the water consumption per hectare ranges from

100 to 600 litres. When using herbicides, which are commonly sprayed on weedy crops bare

of plants, use smaller water quantities (from 100 to 300 litres). Too much water can lower the

spraying efficiency, especially when using herbicides which are absorbed through the leaves

of the weed. When spraying plants with fungicides and insecticides, a higher amount of water

is normally used. Too much water, however, can cause insecticide to drip of the leaves and

therefore loss of insecticide.

Spraying parameter settings should be such

that the overlap of jets between the two

nozzles is minimal.

A – Distance between the nozzles

H – Height of nozzles above the crops

Δ – Sprinkling angle

15.5 Use of tables

15.5.1 Nozzle selection

Example:

You have the following data:

- desired consumption per hectare of 400 l

- working speed: 6 km/h

----------------------------------------------------------------------------------------------------------------

1. In the speed column for 6 km/h of table 2 find the desired consumption per hectare 400 l/ha.

2. See the flow rate of the nozzle on the left side of the table; in our case, this is 2,00 l/min.

3. Select the appropriate nozzle at specific pressure from table 1: e.g. TABLE 1, nozzle LECHLER,

brown colour at a pressure of 3.2 bar.

15.5.2 Selecting appropriate speed and working pressure

Example:

- desired consumption per hectare 400 l/ha

- installed LECHLER nozzle, RED colour

- desired pressure between 2 and 4 bar

- desired working speed between 4 and 6 km/h

----------------------------------------------------------------------------------------------------------------

1. In table 1, find the nozzles, installed in your sprayer. LECHLER RED nozzles have a flow rate of

1.26 l/min at a pressure of 2 bar and a flow rate of 1.8 l/min at a pressure of 4 bar.

2. Find the consumption value of 400 l/ha at a nozzle flow rate between 1.2 and 1.8 l/min in table 2;

find the speeds 4-6 km/h in the vertical column. Results:

- 4,5 km/h at a pressure of 2.8 bar

- 4,8 km/h at a pressure of 3.2 bar...

15.6 Different calculations

- The water consumption values can be taken from the tables or calculated in accordance with

the following equation:

𝑾𝑨𝑻𝑬𝑹 𝑪𝑶𝑵𝑺𝑼𝑴𝑷𝑻𝑰𝑶𝑵 𝑷𝑬𝑹 𝑯𝑬𝑪𝑻𝑨𝑹𝑬 [𝒍𝒉𝒂⁄ ] =

𝟔𝟎𝟎𝒙 𝑵𝑶𝒁𝒁𝑳𝑬 𝑭𝑳𝑶𝑾 𝑹𝑨𝑻𝑬 [𝒍𝒎𝒊𝒏⁄ ]

𝑾𝑶𝑹𝑲𝑰𝑵𝑮 𝑺𝑷𝑬𝑬𝑫 [𝒌𝒎𝒉⁄ ] × 𝑫𝑰𝑺𝑻𝑨𝑵𝑪𝑬 𝑩𝑬𝑻𝑾𝑬𝑬𝑵 𝑵𝑶𝒁𝒁𝑳𝑬𝑺 [𝒎]

- The required flow rate of a nozzle per hectare and the working speed can be calculated with

the help of the following equation:

𝑵𝑶𝒁𝒁𝑳𝑬 𝑭𝑳𝑶𝑾 𝑹𝑨𝑻𝑬 [𝒍𝒎𝒊𝒏⁄ ] =

𝑾𝑨𝑻𝑬𝑹 𝑪𝑶𝑵𝑺𝑼𝑴𝑷𝑻𝑰𝑶𝑵 𝑷𝑬𝑹 𝑯𝑬𝑪𝑻𝑨𝑹𝑬 [𝒍𝒉𝒂⁄ ] × 𝑾𝑶𝑹𝑲𝑰𝑵𝑮 𝑺𝑷𝑬𝑬𝑫 [𝒌𝒎

𝒉⁄ ]

𝟔𝟎𝟎

- The simplest way to determine the tractor’s speed is to measure a certain distance and the

required time to pass this distance:

𝑾𝑶𝑹𝑲𝑰𝑵𝑮 𝑺𝑷𝑬𝑬𝑫[𝒌𝒎𝒉⁄ ] =

𝑫𝑰𝑺𝑻𝑨𝑵𝑪𝑬 𝑻𝑹𝑨𝑽𝑬𝑳𝑬𝑫 [𝒎]×𝟑,𝟔

𝑫𝑹𝑰𝑽𝑰𝑵𝑮 𝑻𝑰𝑴𝑬 [𝒔]

WARNING: Check the actual flow rate of the nozzles by measuring it. If the flow rate of

a nozzle at a specific pressure exceeds the table values for more than 10%, then the

nozzle insert is worn and needs to be replaced .
