Daily Gun Care, Flushing, and Cleaning

WARNING

PRESSURIZED EQUIPMENT HAZARD

To reduce the risk of a serious injury whenever you
are instructed to relieve pressure, follow the 

Pres-

sure Relief Procedure

 on page 9.

CAUTION

Clean all parts with a non-conductive solvent, com-
patible with the fluid being sprayed. Conductive
solvents can cause the gun to malfunction.

Methylene chloride with formic or propionic acid is
not recommended as a flushing or cleaning solvent
with this gun as it will damage aluminum and nylon
components.

CAUTION

Î

Î

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

02027

Do not immerse the gun in solvent.

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

Do not point the gun up while cleaning it.

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