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 fin-
ish. 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 uniform

OPERATION
HVLP
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 out-
side 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.

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.
CLEANING & MAINTENANCE
SIPHON CUP
Turn off air supply. Disconnect cup from
lid. Raise tube out of material and pull
trigger to allow remaining material to
drain back to the cup. Empty the cup of
material. Clean the cup, lid and tube.
Add some thinner to cup. Reassemble.
Turn on air supply and spray with proper cleaning solvent.
Repeat with clean solvent if necessary. Remove solvent, discon-
nect gun, remove air cap 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, un-
screw, realign, and try again. NEVER use excessive force in
matching parts.
