Normally dry ready-mixed materials are used for plaster, either chalk or cement based

This machine cannot pump traditional mortar.

Choice of the pumpDifferent types of pump are available:

STANDARD CONFIGURATION: D6-3 pump (rotor code 250.130, stator code 263.192) with

maintenance free stator, ideal for ready mixed mortars based on gypsum or cement, with granulometry of 3 mm.

OPTIONAL: D4 pump (rotor code 250.131, stator code 263.193) with

maintenance free stator, ideal for ready mixed cement based materials, with granulometry of 5 mm.

D7-2.5 pump (rotor code 250.152, stator code 263.390) with

maintenance free stator, ideal for ready mixed cement based materials, with granulometry of 5 mm.

D8-1.5 pump (rotor code 250.149, stator code 263.381) with

maintenance free stator, ideal for ready plaster, with granulometry of 5 mm.

D8-1.5 pump (rotor with brush code 250.147, stator code 263.381)

with maintenance free stator, ideal for light materials, to be used with the turbo mixer.

D8-2 pump (rotor code 250.155, stator code 263.398) with

maintenance free stator, ideal for lightened materials, with granulometry of 5 mm.

The dry ready mixed material is loaded into the hopper manually by the operator if it is in sacks (the hopper grill has a special sack tearing device) or automatically by a pneumatic transfer system (e.g. SILOTUR manufactured by TURBOSOL PRODUZIONE S.P.A.).

A batcher carries the dry material to the mixing chamber, where it is mixed with water by the mixer. The water flow is regulated by a micrometric tap (15) and is shown by the graduated scale on a flowmeter (16).

A worm-screw pump connected to the mixer sends the material to the place of use where it is sprayed on the walls by a spray gun, which receives both the material and the air sent by the compressor.

Starting and stopping the machine are controlled directly by the spray gun operator, by opening and closing the air tap (17) on the spray gun.

Placing the machineThe machine must be placed in as horizontal a position as possible: the maximum gradient allowed is 5 both lengthwise and crosswise.

The geared motor is blocked in place by its special hook, and if it is not correctly closed the safety device will not allow the machine to start.

The machine must be placed in a spot in the building site where the working range of the hoses can be exploited to the best (15 meters) and where it is easy to wash the machine at the end of the working day.

Before turning the machine on ensure the wheel brake is firmly on.

Prepare all the material for cleaning the machine (water hose, washing sponge, etc.)

Ensure that you have at least 80 cm free space around the machine, free of holes or dangerous protuberances.

4.3 - PRELIMINARY OPERATIONS

Electric connectionsConnect the machine to the site electric board using a neoprene (antiwear rubber) lead, marked H07 RN-F, with a minimum section of:

4 x 6 mm. for distances up to 30 m;4 x 10 mm. for distances up to 50 m.

The use of an electric lead that is too small could jeopardise the machine functions.

The site electric board must guarantee: A minimum output of 12 kW, Efficient grounding system; 35A fuses (type aM) on the machines 32A socket, Highly sensitive circuit breakers (30 mA), It must correspond to current national legislation in

force.

Connect the machine ground terminal to the ground terminal in the site electric board using a lead with a minimum section equal to the section of the power lead, and never less than 16 mm2.

If the machine is powered by a generator, use a set with a minimum output of 25 kVA.

12 13

HosesLay the hoses and limit their length as far as possible (to reduce handling time and wear), checking at the same time that they are in good order.

Use only original hoses and couplings.The couplings must be mounted only by TURBOSOL PRODUZIONE S.p.A. or by specially authorised companies. Under no circumstances shall TURBOSOL PRODUZIONE S.p.A. be held responsible for damage to persons and property due to the use of non-original hoses and couplings.

Spray gunEach spray gun is formed ofa coupling to the material delivery hose (18),a coupling to the air hose (19),an air tap (17),an air nozzle (20)with or without regulation device (21)a deflector (22).

Generally with a smaller diameter deflector the material is sprayed over a wider area and vice versa

Coupling devicesCheck that the couplings are clean and in good working order Cam-locks When connecting the hoses together make sure the

rubber gaskets are mounted (23),

Completely lock the levers.

The hoses are connected to each other with the longest hose (10 m) connected to the machine, gradually reducing the length until the shortest one is connected to the spray gun.

Bonnet (optional)In the event the dry ready mixed material is fed automatically to the hopper by the pneumatic transfer system, a special bonnet can be fitted to the hopper as follows:

Remove the protection grid.

Place the bonnet and cover as shown in the figure and hook it firmly in place (34).

Connect the hose that carries the material from the pneumatic transfer system to the relative attachment (35).

Fit the mechanic level switch (36) in its housing and connect the power lead (37) to the probe and electric power board on the SILOTUR (pneumatic transfer system).

Connect the water intake (32) on the machine to the site water supply using a 3/4 hose (19 mm internal diameter).

When the water pump is connected to a tank the first time (and therefore after each time the hydraulic system is emptied or after a long period of shutdown) the pump must be primed otherwise the mechanic seals could be damaged.To check whether the pump is primed, open the tap (33) and water should come out.

The water flow should be:- at least 600 l/h for cementicious materials,- 1.000 l/h with gypsum materials

The water must be clear without any impurities.

In the event the main water network cannot guarantee a constant flow of water, install a sufficiently large tank (200 litres) to act as backup.The tank must have a tap installed with float, and be in a raised position with respect to the level of the machine, with the water draw off point at least 50 cm above the attachment of the water inlet tap to the machine.

Draw the water off from the tank through a 3/4 hose with filter (supplied).

6 - TROUBLE SHOOTING - CAUSES - REMEDIES

6.1 - NO MATERIAL COMES OUT OF THE GUN

Material delivery hose pluggedA long period of shutdown could cause the material pipe to become plugged: no material comes out of the spray gun and the material hose pressure gauge shows a pressure level above the normal working level.

The normal working pressure shown on the pressure gauge (26), depends on the type of material and length of hoses that are used; this value should be checked frequently to promptly identify any problems.

In this case, open the air tap (17) to the spray gun and the machine will stop, then stop the material pump by pressing the button (52).

Release the pressure from the material delivery hoses, by turning the pump in the opposite direction for a few seconds: open the air tap (17) to the spray gun and invert the pump rotation direction using the special command (43).

Attempt starting again

Keep the working pressure under control and stop the machine promptly if the pressure exceeds the normal value, because In this case the hose is still plugged.Close the air tap (17) to the spray gun and release the pressure from the material delivery hoses by turning the pump in the opposite direction (43) for a few seconds.

The operator must have been specifically trained to carry out this operation.

In particular, before opening a coupling, ensure that there is no residual pressure in the hoses by controlling the pressure gauge (26) and that no-one is standing in the vicinity.Expert personnel must always carry out this potentially dangerous operation exercising the utmost caution.

Stop the pump.

Identify where the material delivery hose is plugged: the hose will be hard and rigid at this point.The most critical points are around the couplings.

Disconnect the plugged hose and hit it with a hammer at the edge of the blockage to break the plug that has formed and allow the hardened material to come out.

Start the pump for a few moments and make sure that the hose is free of the plug, shown by the material flowing out freely.

Reconnect the hose and start work.

22 23

Clogged spray gunEncrusted hardened material, or a deflector with too small a passage for the material being used could cause clogging of the gun.Relieve the pressure in the hoses, by reversing the pump rotation direction for a few seconds.

The operator must have been specifically trained to carry out this operation.

In particular, before opening a coupling, ensure that there is no residual pressure in the hoses by checking the pressure gauge (26) and that no-one is standing in the vicinity.Expert personnel must always carry out this potentially dangerous operation, exercising the utmost caution.

Stop the material pump (52) and for greater safety, turn the machine off (43).

Dismantle the deflector and, if necessary the gun, and remove the cause of clogging.Before reassembling the deflector or spray gun, ensure the nozzle is free (clean If necessary) and that the material flows out freely from the hose.

Worn pumpA worn stator may result in the material flowing out of the gun unevenly or even cause plugging at the beginning of the hose due to overheating the material.

The rotor-stator must be replaced.

If during operations, the material tends to drip from the spray gun, try changing the deflector and/or the nozzle with one with a smaller hole.

If during work, the material arrives Intermittently at the gun, check the air hose for bends or kinks and the air nozzle for clogging.

Motor protector triggersIn the event of problems, one of the motor protectors triggers and the red led (46) lights up on the electric control board.

Open the electric board and check which protection device has triggered: material pump protection (64) compressor or water pump protection (65) batcher protection (66)

Before resetting the relative protection device, eliminate the cause of the fault (see page 24 - 25).
