OPERATION
Proper han dling of the gun is essential for ob tain ing a good finish. The gun should be held at a right angle to the sur face being cov ered, and moved
par al lel with it. For precise con trol of the gun and material, the trigger should be re leased before the end of the stroke.
Hold the gun from 6 to 12 inches away from the surface depending on ma te ri al and at om iz ing pres sure. For a uniform finish, lap each stroke over the
pre ced ing stroke, making sure the spray is smooth and wet.

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-rings or seals in paint thinner. O-rings and seals
can be wiped clean with paint thinner but soaking can cause these items to
deteriorate over time.
7.
caution:
Do not use lubricants which contain sil i cone.
Sil i cone may cause defects in the finish ap pli ca tion.
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, 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.
