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 12.

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

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.

Do not point the gun up while cleaning it.

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

07042A

Do not immerse the gun in solvent.
