SPRAY GUN MAINTENANCE AND CLEANING

You do not need to clean your spray gun every time you stop spraying. Either set the spray gun down carefully so as

not to tip it over, or hang it by the hook provided on the spray gun. You should, however, clean your spray gun at the

end of a work session or at the end of the day. It is not a good idea to leave material in the spray gun overnight.

Also, pay careful attention in keeping the threads on the main gun body clean. Dried material on the threads can

cause the parts to bind.

1. When you have finished spraying, pour the remainder of your material out of the spray gun cup. Pour in a small

amount cleaning fluid. Use a cleaner that is compatible with the coating you just sprayed. (Water if product is

water-soluble). Shake the spray gun gently. Wait about 30 seconds and spray out the cleaner in the cup. To

protect the environment, you can spray the cleaner into a container or into a large rag that you have wadded into

a large ball.

2. If necessary, remove the fluid nozzle (#3). Use the wrench provided to remove the fluid tip. Rinse with

appropriate cleaner.

3. To remove the fluid needle assembly, turn the material adjustment screw (#21) all the way counter (anti)

clockwise until it comes out of the spray gun. Carefully remove the needle return spring (#20). Pull the needle

assembly back towards you and out of the spray gun. Wipe or rinse clean.

4. Wipe all exposed areas clean.

5. Although they might not need attention every time you spray, you should be aware of two additional important

parts on your spray gun. One is the cup gasket (#11) and the gland seal (#26). The cup gasket insures that the

cup is properly sealed to the spray gun body, the cup is properly pressurized and no fluid leaks from the spray

gun cup. Replace if necessary. The gland seal is adjusted by tightening (or loosening) the gland nut (#27). Be

sure that the gland nut is not too tight so that it does not allow free movement of the needle assembly. Be sure

that this nut is not too loose as to permit fluid to leak around the needle. Normally, this is preset at the factory and

should need no adjustment. Replace gland seal when it becomes impossible to prevent leaking.

6. Remove the fan pattern assembly shaft (#7A) by loosening the fan pattern retaining screw (#6). Add gun

lubricant to the 3 areas designated by the arrows in the picture below. Once done, reinstall the shaft making sure

to align the hole next to the knob with the hole for the fan pattern retaining screw. Reinsert the fan pattern

retaining screw, but DO NOT tighten all the way. Only tighten until it is flush with the top of the gun body.

7. Store your spray gun for the next use.

Spray Gun Recommended Maintenance: Check: Cup gasket, gland seal, air cap holes, nozzle/needle assembly every 50

hours or when necessary. Clean or replace parts as needed.
