Important Safety Instructions
1. Always wear eye protection, gloves and respirator to prevent against harmful
vapors while spraying.
2. Never use oxygen or any other combustible or bottle gas as a propellant.
Explosion and serious injury or death may result.
3. Many paints and solvents can be highly flammable. Please use the spray gun
only in well-ventilated areas, do not smoke or use near open flame.
4. Always disconnect the paint gun from air supply when not in use and during
maintenance. For emergency stopping and to prevent unintended operation, a
valve near the gun is recommended.
5. Inspect the tool before each use to ensure there is no leakage or misaligned
parts. Be sure the trigger moves freely.
6. Never use halogenated hydrocarbon solvent, as it can chemically react with
aluminum and zinc parts of this tool.
7. Do not make any modifications to this tool.

Operating Instructions
POWER SOURCE
This tool operates best on a clean, dry supply of compressed air delivered at 29 to
50 psi. Use of a moisture trapping air filter (ATD-7812) is highly recommended as
moisture or foreign matter can damage the internal parts of this tool.
CAUTION: All air pressure in the system should be rated at 29 to 50 psi. Higher or
lower pressure can adversely influence the operation or cause damage to this tool.
NOTE: To maintain a maximum 10 PSI at the nozzle, use a minimum of 29 psi at
the inlet.
TOOL PREPERATION
1. Check tool for worn or damaged parts. Repair or replace as necessary.
2. Check trigger to ensure that it moves freely.
3. Connect tool to air supply.
4. Adjust air pressure based on paint viscosity and paint manufacturer’s
recommendation. (fig 2)
5. Clean paint guns before use, to ensure any factory oils or pigments are not present.
Do not use halogen hydrocarbon or acidic solvents to clean paint guns.
6. Pour paint into cup.

GUN HANDLING
For best results, please follow these basic guidelines:
1. Keep the spray gun perpendicular to the surface. Spraying in an arc will not
give good results. (Fig. 3)
2. Keep gun moving from one side to the other while spraying. If you stop
moving the gun while you are spraying, too much paint will build up and
begin to run. Begin the horizontal movement of the gun before you begin
spraying. Also, keep the gun at a constant distance 6-12 inches from the
surface. (Fig. 4)

ADJUSTMENT
1. Fine-tune the gun to your desired working settings of spray patterns, fluid
output and degree of paint atomization using the three controls illustrated in
Figure 5.

Maintenance
To clean the gun, pour any leftover paint back into its container. Using thinner,
clean out the paint cup and cap. Spray some thinner through the gun to clean the
spray head, needle and nozzle. Spray until thinner comes out clean. Clean all paint
passages as any paint left in the gun and allowed to dry can clog the spray head.
Wipe the exterior of the gun with the cleaning brush included and a soft cloth
moistened with thinner. If you remove the needle, remove the nozzle as well to
protect the seat. NEVER DIG WITH A WIRE OR HARD OBJECT AS THIS CAN
DAMAGE THE NEEDLE SEAT. Remove all such paint before it has a chance to
dry.
