SPRAY GUN
1. Submerge the front end of the gun in solvent just until the fluid
connection is covered.
2. Paint that has built up on the gun should be removed using a
bristle brush and solvent.
3. Never submerge all of the spray gun in sol vent be cause:
• This will dissolve the lubricant in the packings and
on wear surfaces, causing them to dry out and resulting in
difficult operation and faster wear.
• Air passages in the gun will become clogged with dirty
solvent.
4. Using a rag moistened with solvent, wipe down the outside
of the gun.
5. Oil gun daily. Use a drop of lightweight machine oil on:
A. fluid needle packing
B. air valve packing
C. trigger pivot point
See Fig. 1 for Location of
Above Points.
6. NOTE: Do not soak rubber
o-ringsor seals in paint thinner.
O-rings and seals can be wiped
clean with paint thinner but soaking

over time.
7. Caution: Do not use lubricants which
contain sil i cone. Sil i cone may cause

be sure you have the correct parts, un screw, re align, and try again.
NEVER use excessive force in match ing parts.
AIR NOZZLE, FLUID NOZZLE, AIR VALVE ASSEMBLY
1. All nozzles and needles are made to exact stan dards. They
should be han dled carefully.
2. To clean nozzles, immerse them in sol vent until any dried
material is dissolved, then blow them clean.
3. Do not use metal or sharp instrument to probe any of the holes
in the nozzles.
4. Air flow should occur before fluid-flow when the gun is
triggered. It may be necessary to adjust the fluid control screw
to make sure air flows before fluid.
5. Do not alter the gun in any way.
