7. MAINTENANCE
Guards (air motor cover, coupling shields, housings …) have been designed for safe use of
the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or damage to
property due to removal or partial removal of the guards
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.
DON’T SOAK THE GUN INTO SOLVENT TO PREVENT FROM DAMAGING THE SEALS.
8. REPLACEMENT OF THE NOZZLE
Unscrew the nozzle from the nozzle holder (22) and remove the nozzle,
Clean the cover, the threading of the gun head (2) and the threading of the nozzle holder with a dry rag,
Change the nozzle,
Screw the nozzle on the nozzle holder.
9. DISASSEMBLY OF THE GUN FLUID PART
Guards (air motor cover, coupling shields, housings …) have been designed for safe use of
the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or damage to
property due to removal or partial removal of the guards
Unscrew the nozzle from the nozzle holder (22) and remove the nozzle,
Unscrew the needle (21),
Loosen the cup nut (2 turns),
Unscrew the screws (3) and take off the gun head (2) from the body (9),
For the guns, # 101 975 0101 and 101 975 0201, unscrew completely the cup nut, take off the piston
rod guide (6) and the seal (4). For the gun, # 101 975 0102, unscrew completely the cup nut (5), take off
the guide (6), the 'F' washer (23), the 6 seals (24) and the 'M' washer (25).
Clean the parts with a solvent compatible with the material to be sprayed,
Check the parts and change them if necessary.

KREMLIN REXSON Page 10 Manual : 574.107.112
10. DISASSEMBLY OF THE PNEUMATIC PART
Guards (air motor cover, coupling shields, housings …) have been designed for safe use of

closing indicator.
Take off the piston (10), use compressed air with a blower to inject air on the fitting (18). Orientate the
outlet of the piston downwards and prevent the rod (19) from moving back to avoid damaging the seals.
Remove the spring (17) and take off the seal (16),
Take off the rod (19) frontward and the seal (7) from the body (9),
Clean the parts with a dry rag,

12. GUN ASSEMBLY
Guards (air motor cover, coupling shields, housings …) have been designed for safe use of
the equipment.
The manufacturer will not be held responsible for bodily injury or failure and / or damage to
property due to removal or partial removal of the guards
Carry out the assembly on the reverse order of the disassembly. Lubricate the movable parts of the fluid part
with grease and the parts of the pneumatic part with light oil.
IMPORTANT :
-For the guns, # 101 975 0101 and 101 975 0201, the seal (4) assembly is carried out by means of the
tool,
- The rod (19) assembly is carried out frontward of the body to prevent from damaging the seal (7),
-For the gun, # 101 975 0201, assemble the needle (21) and the opening/closing indicator with "Low
strength - Aneorobic adhesive - Loctite".
