PRESSURE HAZARDS
Current legislation requires that an air relief shut off valve is mounted on the supply circuit of the
pump motor to let air off when closing the supply circuit. Without this precaution, the motor residual
air of the motor may let the pump beat and cause a serious injury.
Please ensure that, a material drain valve is mounted on the material circuit to drain it (after
shutting down air to the motor and the pressure relief) before any servicing on the equipment. These
valves must be closed for air and opened for product when processing.
HIGH PRESSURE INJECTION HAZARDS
When working with high pressure equipment, special care is required. Fluid leaks can occur. Then
there are injection risks in exposed parts of body that may cause severe injuries or amputations :
•Medical care must be handled immediately if product is injected under the skin or in other
parts of the body (eyes, fingers).
•Never point the spray gun at any one. Never try to stop the spray with your hands or fingers
nor with rags or similars.
•Follow the shut down procedure and always depressurize air and fluid circuits before
carrying out any servicing on the gun (cleaning, checking, maintenance of the material or
cleaning of the gun nozzles).
For the guns equipped with a safety device, always lock the trigger when you do not start the gun.

06. MAINTENANCE
Before any removal or intervention on the gun, you must isolate it by means of a safety valve (compulsory
upstream of the gun) and ensure that the working pressure has been drained to avoid risks of serious
injuries : spatters especially in eyes or injections under the skin can cause a blood poisoning when using
such material.
The maintenance consists in checking seals as well as the parts of the gun following fluid leaks or only for a
preventive maintenance.
We advice you to change the parts with an unfair wear and tear.
DO NOT SOAK THE GUN INTO SOLVENT TO PREVENT FROM DAMAGING THE SEALS.
07. REPLACEMENT OF THE NOZZLE
¾Unscrew the nozzle from the nozzle holder (25) or unscrew the cover and remove the nozzle,
¾Clean the cover, the threading of the gun head (2) or the threading of the nozzle holder with a dry rag,
¾Change the nozzle,
¾Screw the nozzle on the nozzle holder.
08. DISASSEMBLY OF THE FLUID PART
¾Unscrew the nozzle from the nozzle holder (25) or remove the cover (1) and remove the nozzle,
¾Unscrew the needle (24),
¾Loosen the cup (2 turns),
¾Unscrew the screws (3) and take off the gun head (2) from the body (8),
¾Unscrew completely the cup (5),
¾Clean the parts with a solvent compatible with the material to be sprayed,
¾Check the parts and change them if necessary.
09. DISASSEMBLY OF THE PNEUMATIC PART
¾Unscrew the screws (26),
¾Take off the cover (11) and remove the seal (10),
¾Unscrew the nut (13) and remove the washer (14),
¾Take off the piston (9), use compressed air with a blower to inject air on the fitting (17). Orientate the
outlet of the piston downwards and prevent the rod (18) from moving back to avoid damaging the seals.
Remove the spring (16) and take off the seal (15),
¾Take off the rod (18) frontward and the seal (6) from the body (8),
¾Clean the parts with a dry rag,
¾Check the parts and change them if necessary.
10. GUN ASSEMBLY
Carry out the assembly on the reverse order of the disassembly sequence. Lubricate the movable parts of
the fluid part with grease and the parts of the pneumatic part with light oil.
IMPORTANT :
- the seal (4) assembly is carried out by means of the tool,
- the rod assembly (18) is carried out frontwards of the body to prevent from damaging the seal (6).
