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.
After use, empty any remaining paint from the paint cup, wipe the cup clean with a dry, lint
free rag, and fill with thinners. Spray the thinners through the spray gun until it is clean.
1.
Immerse only the front end of the gun until solvent just covers the fluid connection.
NOTE : do not submerge the entire spray gun in solvent because :
a, the lubricant in the leather packings will dissolve and the packings will dry out.
b, the lubricant at wear surfaces will dissolve resulting in harder operation and
premature wear.
c,
residue from dirty solvent may clog the narrow air passages in the gun.
2.
Use a small bristle brush and solvent to wash off accumulated paint.
3.
Wipe down the outside of the gun with solvent dampened cloth.
4.
Lubricate gun daily, using a light machine oil on :
a, fluid needle packing
b, air valve packing
c,
trigger pivot point
Coat the fluid control spring with vaseline.
CAUTION :
never use silicon based lubricants as this may cause paint finish defects.
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 cup is kept clean. Blockages in this vent will
prevent an even material flow to the gun.
It is possible to strip the fluid nozzle etc for better cleaning as follows.
Unscrew (anticlockwise) and remove the air cap set (01).
Unscrew (anticlockwise) and remove the fluid nozzle (02), (using the spanner
provided).
Unscrew and remove Fluid Control Knob Assy (14).
Carefully withdraw fluid needle (11).
Using the socket spanner unscrew (clockwise), and remove, the brass ring (07).
Using other end of socket spanner unscrew (anticlockwise), and remove, the packing
screw assy (03).
Store all items carefully. reasemble in reverse order.
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.
