Examine the sides of the mixing chamber for scratch-
es and/or material build-up. Carefully, without
scratching the seal surfaces (sides), remove any
accumulated material. Solvent can be used to wash
accumulated material off of chamber, side blocks, etc.
Keep the gun chamber tilted toward the ground so
that solvent does not run back into gun. Certain
solvents will attack o-rings on chamber shaft causing
swelling and deterioration of o-rings.
•
Place generous amounts of high quality, white lithium
grease (Part No. 117773) in each side of the gun
front housing and on the side block seals.
