uniform finish, lap each stroke over the preceding stroke,
making sure the spray is smooth and wet.
Using the lowest possible atomizing air pressure will
reduce overspray and provide maximum efficiency.
Proper handling of the gun is essential for obtaining a
good finish. The gun should be held at a right angle to
the surface being covered, and moved parallel with it.
For precise control of the gun and material, the trigger
should be released before the end of the stroke.
Hold the gun from 6 to 12 inches away from the surface
depending on material and atomizing pressure. For a

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 solvent
because:
• This will dissolve the lubricant in the leather
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. Caution: Do not use lubricants
which contain silicone. Silicone
may cause defects in the
finish application.
AIR NOZZLE, FLUID NOZZLE,
AIR VALVE ASSEMBLY
1. All nozzles and needles are made to exact standards.
They should be handled carefully.
2. To clean nozzles, immerse them in solvent 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.
GRAVITY FEED
Turn off air supply. Remove cover of cup. Empty the cup
of material. Clean the cup and cover. Add some cleaning
solvent to cup. Replace cup cover. Turn on air supply and
spray with proper cleaning solvent. Repeat with clean
solvent if necessary. Remove solvent, disconnect gun,
remove cup cover and clean. Wipe gun and cup with rag
dampened with solvent.
CAUTION…
To avoid cross-threading, all spray gun parts should be
screwed in hand tight initially. If the parts can not easily
be turned by hand , be sure you have the correct parts,
unscrew, realign, and try again. NEVER use excessive
force in matching parts.
