Cylinder Cleaning Instructions
1. Discard all seals, back-up rings and o-rings. Replace
with new items from complete seal kits to help
ensure proper cylinder function.

2. Clean all metal parts with an approved cleaning sol-
vent such as trichlorethylene. Carefully clean cavi-
ties, grooves, threads, etc.

NOTE: If a white powdery residue is present on threads and
parts, it can be removed. Clean the residue away
with a soft brass wire brush prior to reassembly, and
wipe clean before reinstallation.
