Maintenance
WARNING!
Disconnect the spray gun from the air supply, and relieve any pressure in the
gun and hose, before any disassembly.
It is essential that the spray gun is kept clean. Dried paint in the nozzle assembly or
airways will stop the gun from working. For the gun to perform at its best it must be
cleaned and lubricated after every use. It is not recommended that you immerse
the whole gun in solvent or thinners as this could have an adverse effect on the
valve packings and seals and lead to leaks and spitting. Problems caused by
poor cleaning are not covered by your guarantee.
After use, empty any remaining paint from the paint cannister, wipe it clean with
a dry, lint free rag, and fill with thinners. Spray the thinners through the spray gun
until it is clean.
Clean the outside of the gun with thinners and a lint free rag, using a bristle brush
if necessary. The front of the gun can be soaked in thinners if required, but do not
allow thinners to reach the valve packing. The air cap can be removed for
cleaning, but do not poke any of the holes in the air cap or nozzle with metal
instruments. These holes are precision drilled, and can be damaged by probing
with anything harder than a wooden toothpick.
Make sure that the air inlet vent to the paint cannister is kept clean. Blockages in
this vent will prevent an even material flow to the gun.
After cleaning, lubricate the gun. Use a light machine oil on the fluid needle and
air valve packing, and the trigger pivot point. Use vaseline on the fluid needle
spring. Do not use lubricants containing silicon, as these can affect the paint finish.
Do not mix components from spray guns, even those of the same type. Do not
overtighten components, and be careful not to cross thread any parts on assembly.
Check the air supply hose regularly for any signs of damage, and replace it if
necessary. Do not use damaged or leaking hoses.
