USER-MAINTENANCE
INSTRUCTIONS
Procedures not specifically
explained in this manual
must be performed only by a
qualified technician.
TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION:
Turn off the tool, detach the
air supply, safely discharge
any residual air pressure in
the tool, and release the
throttle and/or turn the switch
to its off position before
performing any inspection,
maintenance, or cleaning
procedures.
TO PREVENT SERIOUS
INJURY FROM TOOL
FAILURE:
Do not use damaged
equipment. If abnormal
noise, vibration, or leaking
air occurs, have the problem
corrected before further use.
TO PREVENT EXPLOSION:
Lubricate the tool only
with specified lubricants.
Lubricate the air inlet
using only pneumatic tool
oil. Lubricate the internal
mechanism using only
white lithium grease. Other
lubricants may damage the
mechanism and may be
highly flammable, causing an
explosion.

ing routine maintenance on the air
supply will allow the tool to operate
more safely and will also reduce wear
on the tool.

spection:

cleaned, inspected, and lubricated by
a qualified technician.
