7.3.4 Gun maintenance
Good maintenance of the gun and all its parts is essentially important to guarantee efficient gun operation.
Disassemble the gun by screwing out its screws [P]. Screw out the nozzle locking the nut [R] and estract the
nozzle [Q]. Screw out the nozzle-holder [T] from the gun and check the condition of the inert hose [U] and of
the valve [V]. Replace the pneumatic valve if necessary.
If you have an HELIX gun, check the helix [Z].
