CARE AND MAINTENANCE

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 the spray gun in solvent as:
a. Air passages in the gun will become clogged with dirty solvent.
b. This will dissolve the lubricant in the leather packing and on wear surfaces,
causing them to dry out resulting in difficult operation and faster wear.
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. 14 for location of the above points.
CAUTION: Do not use lubricants which contain silicone. Silicone may cause defects in the finish application.
