MAINTENANCE INSTRUCTIONS

1. Keep safety decals and signs clean and legible at all times.

2. Replace safety decals and signs that are missing or have become illegible.

3. Replaced parts that displayed a safety sign should also display the current sign.

4. Safety decals or signs are available from your dealer’s Parts Department or our Cedar Rapids factory.

INSTALLATION INSTRUCTIONS

1. Clean SurfaceWash the installation surface with a synthetic, free-rinsing detergent. Avoid washing the surface with a soap containing creams or lotion. Allow to dry.

2. Position Safety DecalDecide on the exact position before application. Application marks may be made on the top or side edge of the substrate with a lead pencil, marking pen, or small pieces of masking tape. NOTE: Do not use chalk line, china marker, or grease pencil. Safety decals will not adhere to these.

3. Remove the LinerA small bend at the corner or edge will cause the liner to separate from the decal. Pull the liner away in a continuous motion at a 180-degree angle. If the liner is scored, bend at score and remove.

4. Apply Safety Decala. Tack decal in place with thumb pressure in upper corners.b. Using firm initial squeegee pressure, begin at the center of the decal and work outward in all directions with

overlapping strokes. NOTE: Keep squeegee blade even—nicked edges will leave application bubbles.c. Pull up tack points before squeegeeing over them to avoid wrinkles.

5. Remove Pre-maskIf safety decal has a pre-mask cover remove it at this time by pulling it away from the decal at a 180 degree angle. NOTE: It is important that the pre-mask covering is removed before the decal is exposed to sunlight to avoid the pre-mask from permanently adhering to the decal.

6. Remove Air PocketsInspect the decal in the flat areas for bubbles. To eliminate the bubbles, puncture the decal at one end of the bubble with a pin (never a razor blade) and press out entrapped air with thumb moving toward the puncture.

7. Re-Squeegee All Edges.

unit.18. Read, understand and follow instructions and

precautions given by the manufacturer or supplier of materials to be spread. Improper selection, application, use or handling may be hazardous to people, animals, plants, crops or other property.

CAUTION

If spreader is used to transport chemicals, check with your chemical supplier regarding DOT (Department of Transportation) requirements.

19. Cover all loads that can spill or blow away. Do not spread dusty materials where dust may create pollution or a traffic visibility problem.

20. Turn slowly and be careful when traveling on rough surfaces and side slopes, especially with a loaded spreader. Load may shift causing unit to tip.

21. Read and understand the precautionary decals on the spreader. Replace any that become defaced, damaged, lost or painted over. Replacement decals can be ordered from your dealer’s parts department or from Highway Equipment Company by calling (319) 363-8281 or 1-800-363-8006.

11. Inspect spinner fins, spinner frame mounting and spinner fin nuts and screws every day. Look for missing fasteners, looseness, wear and cracks. Replace immediately if required. Use only new SAE grade 5 or grade 8 screws and new self-locking nuts.

12. Inspect all bolts, screws, fasteners, keys, chain drives, body mountings and other attachments periodically. Replace any missing or damaged parts with proper specification items. Tighten all bolts, nuts and screws to specified torques according to the torque chart in this manual.

13. Shut off engine before filling fuel and oil tanks. Do not allow overflow. Wipe up all spills. Do not smoke. Stay away from open flame. FIRE HAZARD!

GENERAL SAFETY RULESMAINTENANCE SECTION

7. Some parts and assemblies are quite heavy. Before attempting to unfasten any heavy part or assembly, arrange to support it by means of a hoist, by blocking or by use of an adequate arrangement to prevent it from falling, tipping, swinging or moving in any manner which may damage it or injure someone. Always use lifting device that is properly rated to lift the equipment. Do not lift loaded spreader. NEVER LIFT EQUIPMENT OVER PEOPLE.

8. If repairs require use

of a torch or electric welder, be sure that all flammable and combustible materials are removed. Fuel or oil reservoirs must be emptied, steam cleaned and filled with water before attempting to cut or weld them. DO NOT weld or flame cut on any tank containing oil, gasoline or their fumes or other flammable material, or any container whose contents or previous contents are unknown.

9. Keep a fully charged fire extinguisher readily

available at all times. It should be a Type ABC or a Type BC unit.

10. Cleaning solvents should be used with care.

Petroleum based solvents are flammable and present a fire hazard. Don’t use gasoline. All solvents must be used with adequate ventilation, as their vapors should not be inhaled.

1. Maintenance includes all lubrication, inspection, adjustments (other than operational control adjustments such as feedgate openings, conveyor speed, etc.) part replacement, repairs and such upkeep tasks as cleaning and painting.

2. When performing any

maintenance work, wear proper protective equipment—always wear eye protection—safety shoes can help save your toes—gloves will help protect your hands against cuts, bruises, abrasions and from minor burns—a hard hat is better than a sore head!

3. Use proper tools for the job

required. Use of improper tools (such as a screwdriver instead of a pry bar, a pair of pliers instead of a wrench, a wrench instead of a hammer) not only can damage the equipment being worked on, but can lead to serious injuries. USE THE PROPER TOOLS.

4. Before attempting any maintenance work (including

lubrication), shut off power completely. DO NOT WORK ON RUNNING MACHINERY!

5. When guards and covers are removed for any

maintenance, be sure that such guards are reinstalled before unit is put back into operation.

6. Check all screws, bolts and nuts for proper torques

before placing equipment back in service. Refer to torque chart in this manual.

GENERAL SAFETY RULESMAINTENANCE SECTION CONTINUED

11. When batteries are being charged or discharged, they generate hydrogen and oxygen gases. This combination of gases is highly explosive. DO NOT SMOKE around batteries—STAY AWAY FROM FLAME—don’t check batteries by shorting terminals as the spark could cause an explosion. Connect and disconnect battery charger leads only when charger is “off”. Be very careful with “jumper” cables.

12. Batteries contain strong sulfuric acid—handle

with care. If acid gets on you, flush it off with large amounts of water. If it gets in your eyes, flush it out with plenty of water immediately and get medical help.

13. Hydraulic fluid under high pressure leaking from a pin hole are dangerous as they can penetrate the skin as though injected with a hypodermic needle. Such liquids have a poisonous effect and can cause serious wounds. Get medical assistance if such a wound occurs. To check for such leaks, use a piece of cardboard or wood instead of your hand. The fine spray from a small hydraulic oil leak can be highly explosive—DO NOT SMOKE—STAY AWAY FROM FLAME OR SPARKS.

GENERAL SAFETY RULESINSTALLATION INSTRUCTIONS

6. Do not weld on v e h i c l e f r a m e as such w e l d i n g can lead to fatigue crack ing and must be avoided. When drilling holes in frame member, drill only through the vertical web portions do not put holes in top or bottom flanges. Refer to truck manufacturer’s recommendations.

7. Be sure that welds between mounting bars and

sill or between mounting angles and spreader cross sills are sound, full fillet welds. Center mounting angles so that good fillet welds can be made on three sides—and edge bead weld is not a satisfactory weld for this service. Use 309 rod/wire for carbon steel and 409 steel. On 304 stainless steel bodies use SAE grade 5 bolts—welding is recommended if type 308 welding rod is available.

8. Install controls so that they are located of convenient use. Position them so that they do not interfere with any vehicle control and that they do not interfere with driver or passenger or with access to or exit from the vehicle.

9. Check for vehicle visibility, especially toward the

rear. Reposition or add mirrors so that adequate rearward visibility is maintained.

10. Add Caution, Warning, Danger and Instruction

decals as required. Peel off any label masking which has not been removed.

11. Install all guards as required.

12. Check installation completely to be sure all fasteners are secure and that nothing has been left undone.

1. The selection of the vehicle on which a spreader body is to be mounted has important safety aspects. To avoid overloading:

a. Do not mount spreader on a chassis which, when fully loaded with material to be spread, will exceed either the Gross Axle Weight Rating (GAWR) or the Gross Vehicle Weight Rating (GVWR) for the chassis.

b. Do install the spreader only on a vehicle with cab-to-axle dimension recommended for the spreader body length shown.

2. Follow mounting instructions in the Installation

section of this manual. If mounting conditions require deviation from these instructions refer to factory.

3. When making the installation, be sure that the

lighting meets Federal Motor Vehicle Safety Standard (FMVSS) No. 108, ASABE S279 and all applicable local and state regulations.

4. When selecting a PTO to drive hydraulic pump, do

not use a higher percent speed drive than indicated in the Installation section of this manual. Too high a percent PTO will drive pump at excessive speed, which can ruin the pump, but more importantly, will overheat the hydraulic oil system and increase

the possibility of fire.

5. W h e n truck frame must be shortened, cut off only the portion that extends behind rear shackle in accordance with the truck manufacturer’s recommendations. If a torch is used to make

the cut, all necessary precautions should be taken to prevent fire. Cuts should not be made near fuel tanks and hydraulic oil reservoirs, fuel, brake, electric or hydraulic lines and such lines should be protected from flame, sparks or molten metal. Tires should be removed if there is any chance of their being struck by flame, sparks or molten metal. Have a fire extinguisher handy.

GENERAL DESCRIPTION

The 7020 is a hopper-type spreader designed for spreading bulky materials, such as lime, gypsum, chicken litter, dry feedlot manure, marl, paper mill sludge, packing house refuse, etc. It is intended for truck chassis vehicle mounting.

The unit is powered hydraulically and provides independent variable speed control for the spinner and full automatic ground speed control for the conveyor by means of a motorized valve with shaft sensor or Mark series control system. The hydraulic pump which provides the hydraulic power is a gear-type pump and is driven by means of a transmission PTO.

The conveyor runs the full length of the hopper bottom to deliver material to the spinner through an adjustable hydraulically operated gate at the rear of the hopper body. The conveyor is driven by two orbital type hydraulic motors mounted to a 6 to 1 ratio spur gear case. There are a variety of pintle-type chain conveyors for different applications: a #1 chain conveyor with cross bars every fourth link, a #2 with cross bars every other link, a #3 with cross bars every link or a #4 belt-over-chain conveyor, for better conveyor sealing when hauling wetter materials.

The distributor spinner assembly has two 24 inch diameter dished discs. Each disc has four formed and heat-treated fins that are adjustable to radial angle. The spinner is fully adjustable by means of a rotating handle.

The optional agitators are used to break down high moisture product or coarse material with bridging characteristics.

This product is intended for commercial use only.

7020HI-WAYHEADERGENERAL OPERATING PROCEDURES

The following procedure is a guide:

1. Field test over any suitable course which allows vehicle to be driven at speeds to be used while spreading. 2. Make sure unit has been properly serviced, that oil reservoir is full and gate valve under reservoir is fully open.

Do not load spreader.3. Manual spinner control valve: Set to position “5”.

DANGER

Take proper safety precautions when observing conveyor and spinner speed while vehicle is in motion! These may include use of suitable mirrors clamped to permit observation by a safely seated observer, following the spreader in another vehicle at a safe distance, or other suitable means. Do not stand on fenders, in body or on any part of spreader as there is danger of falling off the vehicle or into moving parts! Use great care in performing this test!

4. Start truck engine. Turn control to “on’’ position. Engage PTO and allow to run at fast idle long enough to bring hydraulic oil up to operating temperature. Spinners should revolve at moderate speed and the conveyor should not move.

5. Set program to operational mode and begin forward travel. Move conveyor switch to “on’’ position. Conveyor should start immediately when vehicle moves and should continue to run at speeds which should vary directly with the vehicles road speed; the conveyor should speed up as truck speed increases and slow down as truck speed reduces. Spinner speed should remain constant when engine speed is above minimum operating range.

2. Fill body with material to be spread.3. Drive to location where spreading is to be done. 4. Adjust spinner control valve for material being applied to give spread width desired. See G4 Spread Pattern

section.5. Adjust spinner to give spread pattern desired. See G4 Spread Pattern section.6. Using Spread Rate graphs in controller manual, set feedgate opening to obtain yield desired.7. If truck has a two-spread rear axle place it into “Low” range.8. Make sure shut-off valve on hydraulic reservoir is fully opened.9. Start truck engine.

10. Turn on power to controller and set program to desired values.11. Engage pump drive PTO.

CAUTION Drive only at speeds which permit good control of vehicle!

12. Drive at speeds that allow engine to turn at proper RPM.

Higher transmission gears may be used with speeds to 30 MPH. If lower speeds must be used, shift transmission into lower gears so that engine speed can be maintained to allow adequate hydraulic oil delivery from pump.

NOTICE! CHANGE HYDRAULIC OIL FILTER AFTER FIRST WEEK (OR NOT MORE THAN 50 HOURS) OF OPERATION ON A UNIT.

*Visit www.newleadervip.com for interactive tools to calculate yield, proper feedgate opening, conveyor revolutions per minute, and mph to maximize the performance of your spreader.

AGITATORS

NOTICE!Transporting product can cause loads to compact, which may cause increased hydraulic startup pressures. Conveyor must be running before agitators are used to break down product or damage to unit may occur.

Break down bridging product by first running the conveyor to dispense product through the endgate. If product stops dispensing, activate lower agitator to break down suspended product. If product stops dispensing with both the conveyor and lower agitator operating, activate upper agitator to break down the remaining product.

7020HI-WAYHEADERLUBRICATION AND MAINTENANCE

PREVENTATIVE MAINTENANCE PAYS!

A frequent, periodic preventative maintenance program should be established to prevent rapid damage to spreading equipment. Proper cleaning, lubrication and maintenance will provide longer life, more satisfactory service and more economical use of the equipment.

WARNING Shut off all power before performing any maintenance operation. Otherwise, you could be injured.

WARNINGTurn off all power, set vehicle brakes, lock engine starting switch and remove keys before getting into dump body. Tag all controls to prohibit operation. Tags should be placed, and later removed, only by the person working in the body.

HYDRAULIC SYSTEM

The use of proper oil in the hydraulic system is one of the most important factors for satisfactory operation. Utmost cleanliness in handling the oil cannot be stressed enough. Keep the hydraulic oil in original closed containers, clean top of container before opening and pouring, and handle in extremely clean measures and funnels.

Refer to the Lubricant and Hydraulic Oil Specifications section of the manual for selection of the proper hydraulic fluid for use in the hydraulic system.

Service Schedule

1. Check the hydraulic oil daily by means of dipstick. Add oil if required. Periodically inspect the hoses and fittings for leaks.

NOTICE! 2. CHANGE THE HYDRAULIC OIL FILTER AFTER THE FIRST WEEK (OR NOT MORE THAN 50 HOURS) OF OPERATION ON A UNIT.

3. After first filter change, replace filter when indicator reaches Danger Zone.4. The reservoir should be drained through drain plug (not through suction outlet), flushed, and refilled annually,

or the oil should be changed if it shows any signs of breaking down under continued high-pressure operation. Discoloration of oil is one sign of breakdown.

AGITATOR GEAR CASE

Disassemble gear case once a year. Wash all parts in clean solvent. Refill with recommended lubricant.

CONVEYOR GEAR CASE

The oil in a new unit should be drained at the end of the first two weeks (or not more than 100 hours) of operation and the case should be thoroughly flushed with light oil. Refer to the Lubrication Specifications section for the proper grade oil. Refill 50:1 gear case with two and a half (2 1/2) pints (1.18 liters) of recommended lubricant. Refill 6:1 gear case with one pint (.47 liters) of recommended lubricant. After the initial change, the oil should be changed ever 2,000 hours of operation or annually, whichever occurs first.

Check the level in the gear case weekly.

CONVEYOR CHAIN

DANGER

When conveyor is running, stay out of the body. Stay clear of all moving parts. Entanglement of clothes, any part of your body or anything you have in your hands can cause serious injury. Do not use a bar, rod or hammer on conveyor while it is moving--if it gets caught it could cause injury. With the spinner shut down and the conveyor running slowly, spray the mixture of oil between the links of the chain by spraying through openings at the rear end of sill or from front outside body when access clearance is adequate. Do this at least once a week and after each time the machine is washed down. Allow to become dry before lubricating.

Hose down the machine and remove any material build-up on the sprockets or under the chain. If material is allowed to build up, the chain may ride up and damage the chain or body. NOTE: If material builds up under the chain, the chain will ride on the material instead of the bottom panel. The more material allowed to build, the closer the chain will come to the chain shields. If the chain should catch a chain shield, it could permanently distort the chain, the chain shields or the body. In the same manner, if material is allowed to build up on the sprockets, the chain will have a larger diameter to follow. The more material allowed to build up, the closer the chain will run to the chain shields, until damage has occurred. Do not remove material while conveyor or spinner is running.

Lubricate the conveyor chain at least once a week. Use a mixture of 75% diesel fuel and 25% SAE 10 oil in a pressurized hand spray gun. Spray oil mixture between links of chain through openings provided at rear end of sill or from front outside body when clearance is adequate. After each washing, allow to dry, then lubricate.

If a chain oiler is used, fill the oiler reservoir daily with a mixture of 75% diesel fuel and 25% SAE 10 oil. Before each filling of the spreader with material to be spread, open petcock and run the conveyor until the full length of chain has been oiled, then shut petcock.

Proper chain tension is also a factor in chain and sprocket life. The proper chain tension is illustrated in Figure 1. Be sure the chain is tensioned equally on both sides. This adjustment is made on each side of the unit at the idler bearings.

Figure 1 - Chain Tension to be Measured from Rear of Sill - Proper Tension 36” to 40” (91.4 to 101.6 cm).

Figure 1 - Adjusting Chain Tension

Conveyor chains that are too tight will tend to stretch. This will cause excess sprocket wear and eventually cause breakage. Excess slack presents the possibility of the chain catching on sub-frame parts. Bent or distorted chain bars will cause damage to the body as well. Straighten or replace bent or distorted chain bars immediately.

CONVEYOR BELT MAINTENANCE

Standard belt for the #4 chain is moderate oil resistant that is impervious to moisture, weathering, or normal action which can be used with chemical impregnated fertilizer or oil based additives.• Inspect belt fastener occasionally for wear or “raveling” of belt grip area. • Make sure belt connecting pin is positioned correctly as shown in Figure 2.

NOTICE!Pin must not rotate. If pin ends are not bent down and tight against lacing, the ends may cut into the chain shield sealers or belt wipers.

BOTH PIN ENDS MUST BE BENT DOWN & TIGHT AGAINST ENDS OF LACING

Figure 2 - Conveyor Belt Pin Installation LUBRICATION OF BEARINGS

Grease in a bearing acts to prevent excessive wear of parts, protects ball races and balls from corrosion and aids in preventing excessive heat within the bearing. It is very important the grease maintains its proper consistency during operation. It must not be fluid and it must not channel.

Be sure all fittings are thoroughly cleaned before grease is injected. Points to be lubricated by means of grease gun have standard grease fittings.

Pump grease slowly into bearings until it forms a slight bead around the seals. This bead indicates adequate lubrication and also provides additional protection against the entrance of dirt.

CLEAN UP

For maintaining minimum maintenance operation, this equipment should be thoroughly washed every two (2) to three (3) days during the operating season. Hose the unit down under pressure to free all sticky and frozen material.

It is important that the machine be thoroughly cleaned at the end of each operating season. All lubrication and maintenance instructions should be closely followed. For longer life, repaint worn spots to prevent formation of rust.

FASTENERS

Tighten all screw fasteners to recommended torques after the first week of operation and annually thereafter. If loose fasteners are found at any time, tighten to the recommended torques. Replace any lost or damaged fasteners or other parts immediately upon finding such damage or loss. Check body mounting bolts every week.

LUBRICANT AND HYDRAULIC OIL SPECIFICATIONS

NOTICE!

The lubricant distributor and/or supplier is to be held responsible for the results obtained from their products. Procure lubricants from distributors and/or suppliers of unquestionable integrity, supplying known and tested products. Do not jeopardize your equipment with inferior lubricants. No specific brands of oil are recommended. Use only products qualified under the following oil viscosity specifications and classification recommended by reputable oil companies.

HYDRAULIC SYSTEM

The recommended lubricant to use is an automotive engine oil SAE 15W-40 for diesel engine service. The normal system operating temperature range, with 15W-40 oil, is between 140° and 180° F. Extreme operating temperatures may require a different viscosity oil range. If the temperature rises above 180° there may be defective components in the system causing excessive heat. Consult your dealer or the Product Support Department at Highway Equipment Company for additional information.

GEAR CASE LUBRICANT

Worm (50:1) gear cases are factory equipped with synthetic oil for best performance at high loads.

Lubricate 6:1 gear case assemblies with non-corrosive type SAE 90 EP (extreme pressure) gear oil conforming to MIL-L2105 B multi-purpose gear lubricating oil requirements (API Service GL 4) with ambient temperatures from 40° to 100° F. Ambient temperatures below 40° F. require SAE 80 EP lubricant; above 100° F. use SAE 140 EP grade oil.

Lubricate the gear cases with multi-purpose gear lubricating oil conforming to MIL-L2105 B according to the chart below:

Part Refill Quantity 40° to 120° F Below 40° F50:1 Gear Case -

Agitator 2.5 pints (1.18 liters) SAE 85W 140 SAE 88W 90

6:1 Gear Case - Conveyor Drive 1.5 pint (.71 liters) SAE 80 or 90W SAE 80 or 90W

PRESSURE GUN LUBRICANT

Use a ball and roller bearing lithium base lubricant with a minimum melting point of 300 F. This lubricant should have a viscosity which assures easy handling in the pressure gun at prevailing atmospheric temperatures. The lubricant must be waterproof. The grease should conform to NLGI No. 2 consistency.

CHAIN OILER LUBRICANT

Use a mixture of 75% No. 1 or No. 2 diesel fuel or kerosene mixed with 25% SAE 10 engine oil.

TROUBLESHOOTING

• Symptom: Spinner motors do not turn when spinner control valve is in running position or conveyor does not run when function knob . See reasons 1, 2, 3, 4, 5, 7, 8 & 9.

• Symptom: Spinners turn but conveyor does not run in manual mode. See reasons 6, 8, 9, 10 & 22.

• Symptom: Console in operation mode, but the conveyor does not move when the machine moves. See reasons 6, 8, 9, 10 & 22.

• Symptom: Spinner speed does not stay constant. See reasons 4, 5, 11, 12 & 13.

• Symptom: Spinners run with cab control in “Off” position. See reason 14.

• Symptom: Hydraulic oil overheats (200° F (93.33° C). or hotter). See reasons 1, 4, 6, 15, 16, 17 & 18.

• Symptom: Light flashes and buzzer sounds intermittently. Conveyor runs in jerks. See reasons 19 & 22.

• Symptom: Conveyor does not run with cab control “On”, PTO engaged and vehicle driving forward. See reasons 20 & 22.

• Symptom: Conveyor runs when control switch in cab is in “Off” position. See reasons 15 & 21.

• Symptom: Conveyor starts to run when PTO is engaged. See reasons 15, 20, 21 & 22.

• Symptom: Controller application or programming. Refer to the control manual’s Troubleshooting section.

• Symptom: Undesirable spread pattern. See G4 spread pattern section at the back of this manual.

Reason: Correction:1. Hydraulic oil level low. Add hydraulic oil to reservoir to maintain level around mid-

point of sight gauge.2. Shut Off valve on oil reservoir not open. Open valve fully by turning counter clockwise until it stops.3. Hydraulic Pump is not rotating. 1. PTO is disengaged. Shift into engagement.

2. Drive line has failed. Repair or replace.3. Key in pump shaft has failed. Replace key.4. U-joint pin or key has failed. Replace pin or key.

4. In line relief valve set too low. In line relief valve pressure should be 3100 PSI (213.7 bar) . If unit is not equipped with a pressure gauge, install one at main relief valve. Disconnect pressure line from main relief valve and reconnect to flow meter and load valve. Open load valve fully and run truck engine at field operating speed with pump engaged. Slowly close load valve until pressure reaches 3100 PSI (213.7 bar). If this pressure cannot be reached, adjust relief valve until gauge reads 3100 PSI (213.7 bar).CAUTION: Do not set pressure above 3100 PSI (213.7 bar).

5. Worn pump. With flow meter arranged to check relief valve setting above, open load valve fully. Read flow rate with truck engine running at field operating speed. Close load valve until pressure reads 2000 PSI (137.9 bar). Flow rate should not decrease more than ten percent. If flow loss is greater, replace pump.

Reason: Correction:6. Conveyor relief valve open to return line. Using relief valve testing adapter and flow meter, test valve for

opening pressure. If not 2000 PSI (137.9 bar), replace relief valve.

7. Jammed or frozen spinner motors. Free up. If not possible, replace as required.8. Jammed or frozen conveyor. Free up conveyor.9. Jammed or frozen conveyor hydraulic motor. Replace motor.10. Conveyor hydraulic motor shaft key sheared. Replace key.11. Pump speed is not adequate to provide

sufficient flow to maintain spinner speed.Increase engine speed.

12. Insufficient hydraulic oil flow at normal driving speeds.

Check PTO-Pump matching. If insufficient flow results, install higher percent PTO or use larger pump (Special).

13. Defective spinner control valve. Replace valve metering spool spring. If no improvement, replace spinner control valve.

14. Cab control is for conveyor only—spinners run anytime vehicle engine is running, PTO is engaged and spinner control valve is in a running position.

None required. This is a normal condition. To stop spinners, set spinner control valve at “O” position, disconnect PTO, or shut off vehicle engine.

15. Excessive oil is being pumped. 1. PTO percentage too high. Change PTO to smaller percentage or use smaller pump.

2. Pump is too large. Do not exceed 40 GPM (151.4 LPM) pumping rate. Change to smaller pump or use smaller percentage PTO.

3. Pressure drop in control valve is sufficient to run lightly loaded conveyor motor. Shut off pump drive by disengaging PTO shaft.

16. Worn motor (spinner or conveyor) Motor heats up at an excessive rate (check for this heating when system is cold.) Replace motor.

17. Improper or deteriorated hydraulic oil. Replace hydraulic oil with proper specification oil and replace filter.

18. Pinched or obstructed hose, hydraulic line or fitting.

Clear obstruction or replace part. Straighten kinked hoses.

19. Driving too fast for application rate. Shift truck transmission to a lower gear. Will not normally occur if within maximum application rates.

20. Defective radar. Check speed on console. Repair or replace radar as required.21. Control processor’s power is in “Off” position. Turn on control processor.22. Involves the controller. Refer to control manual.
