WARNING
If any of the following symptoms appears during
operation, stop using the tool immediately, or serious
personal injury could result. Only qualified persons or
an authorised service centre can perform repairs or
replacement of the tool.
Disconnect tool from the air supply before attempting
repair or adjustment. When replacing O-rings or cylinder,
lubricate with air tool oil before assembly.

clutch parts, i.e. a typical oiled/lubricated tool requires
14.20 ml (1/2 ounce) of oil.
