INSTRUCTIONS
Procedures not specically
explained in this manual must
be performed only by a qualied
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 Trigger 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
specied 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 ammable,
causing an explosion.
Cleaning, Maintenance, and
Lubrication
Note: These procedures are in addition to
the regular checks and maintenance
explained as part of the regular operation
of the air-operated tool.
Daily - Air Supply Maintenance:
Every day, perform maintenance on the
air supply according to the component
manufacturers’ instructions. The
lubricator’s oil level needs to be
maintained and the moisture lter must
be regularly drained. Performing routine
maintenance on the air supply will allow
the tool to operate more safely and will
also reduce wear on the tool.
After each use, wipe off the tool, clean
out any accumulated saw dust, and
replace the sandpaper as needed.
If the Trigger (26) begins to stick, apply a
few drops of oil and pump the Trigger to
distribute the oil.
