Daily Cleaning
1. Follow Pressure Relief Procedure,
page 5.

3. Check for fluid leakage from gun and
fluid hoses. Tighten fittings or replace

4. Flush gun before changing colors and
when you are done spraying.
5. Remove cup and filter and clean them
(gravity feed models only).
6. Remove air cap (1) and nozzle (2) as
instructed on page 8 and soak them in
compatible solvent.
7. Use a rag moistened in solvent to wipe
down outside of gun.
8. Before reinstalling air cap and nozzle, clean
them and front of gun with a soft-bristle
brush dipped into compatible solvent.
Do not use a wire brush or metal tools.
To clean out air cap holes, use a soft
implement, such as a toothpick.

CAUTION
• Do not submerge gun in solvent. Solvent
dissolves lubricant, dries out packings, and
may clog air passages. You can immerse
front end of gun in solvent just until cup
connection is covered.
• Do not use metal tools to clean air cap
holes as this may scratch them and distort
the spray pattern.
• Use a compatible solvent.
CAUTION
Trigger gun and use gun tool (27) whenever
you tighten or remove nozzle (2) to avoid
damaging needle seat and nozzle.
