instructions closely.
WARNING!
Potential hazard that could result in serious injury or loss of life.
• If any of the following symptoms appears while the tool is in use, turn it off and
disconnect it from the air supply immediately. Failure to heed this warning will
result in serious personal injury.

PROBLEM POSSIBLE CAUSES SOLUTIONS
Tool runs at normal
speed but loses
power under load.
1. Motor parts are worn or
damaged.
2. Cam clutch is worn or stuck due
to lack of lubricant.
1. Lubricate clutch housing.
2. Check for excess clutch oil. Clutch cases
should only be half filled, overfilling can
cause drag on high speed clutch parts, e.g., a
typical oiled/lubricated wrench requires ½ oz
of oil.
Grease lubrication:
Heat is generated due to insufficient grease in
the chamber. Severe operating conditions may
require frequent lubrication.
If the problem persists, send tool for servicing
or return it to the store.
Tool runs at low
speed. Air flows
slightly from exhaust.
1. Motor parts are jammed with dirt.
2. Power regulator is in closed
position.
3. Air flow is blocked by dirt.
1. Check whether there is blockage in air inlet
and filter.
2. Pour pneumatic tool oil into air inlet as per
instructions.
3. Operate the tool by reversing rotation of
the tool to back and forth directions in short
duration. Repeat the above steps as needed.
