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.
