Daily Gun Maintenance

General Tasks

Follow the Pressure Relief Procedure, page 8.

Frequently lubricate the gun moving parts with a drop of non-silicone oil.

Do not disassemble the spray gun if you are having a spray pattern problem. See Troubleshooting, page 11, for information on how to correct the problem.

Clean the fluid and air line filters daily.

Check for fluid leakage. Tighten fittings or replace equipment as needed.

CAUTION

Solvent left in gun air passages could result in a poor quality paint finish. Do not use any cleaning method that may allow solvent into the gun air passages.

Do not point gun up while cleaning it.

Do not wipe gun with a cloth soaked in solvent; wring out the excess.

Do not immerse the gun in solvent.

Flush

Flush before using the equipment, before changing colors, and when you are done spraying. Use solvent that is compatible with gun wetted parts and with the fluid that will be sprayed.

See Compliant Cleaning Methods,

Do not use metal tools to clean air cap holes as this may scratch them and distort the spray pattern.

Use a compatible solvent.
