20. Clean and inspect all parts. Replace the silencer
if it cannot be cleaned. If any kits are used, use all
parts in the kit. Replace any other parts that are worn
or show signs of disintegration due to the corrosive
effects of some of the fluids.
NOTE: This procedure does not include the
disassembly of the air-valve as described in the Air-

section of the service sheet.

the gasket on the two metal pins on body A (25).

the two "O" rings (6 & 7), apply a little general-
purpose grease to the "O" rings.
