Replacing the check valve Retainer, valve Seal
and air Tube
The check valve is a one-way valve designed to allow air into the
cup, pressurizing the cup's contents. Because it is a one-way
valve, it prevents paint from seeping up the air tube into the air
passages of the gun. It also eliminates any delay in material flow
when the gun is triggered by maintaining pressure in the cup.
The check valve rotates open easily for cleaning. It contains
a valve seal that can be removed and cleaned with soap and
water for waterborne materials or a compatible solvent for other
materials. To replace the the valve seal and/or the air tube:
1. Unscrew the check valve retainer by turning it
counterclockwise.
2. Pull the valve seal out of the gun head. Clean or replace
the valve seal.
NOTE: The check valve area inside the gun head should
also be cleaned of any accumulated spray
material. DO NOT use anything metal or abrasive
to clean the check valve area as it will scratch
the metal surface, and the valve seal will not seal
properly.
3. Reinstall the valve seal. Insert the stem of the valve seal
into the hole of the gun head.
