Problem
Possible Cause
Note: Repairs should be carried out by a qualified person.
Suggested Solutions
Motor parts worn
Cam clutch worn or sticking due to lack of
lubricant
Have a qualified technician replace worn parts
1. Lubricate clutch housing.
2. Check for excess clutch oil.
3. Overfilling can cause drag on high speed clutch parts,
ie, a typical oiled/lubricated wrench requires
1/2 oz. of oil.
Grease lubricated note:
Heat usually indicates insufficient grease in chamber,
Severe operating conditions may require more frequent
lubrication.
Motor parts jammed with dirt particles.
Power regulator in closed position.
Air flow blocked by dirt.
1. Check air inlet filter for blockage.
2. Pour air tool lubricating oil into air inlet
as per instructions.
3. Operate tool in short bursts quickly reversing rotation
back and forth where applicable.
4. Repeat above as needed. If this fails, return to
service center.
Tool will not run. Air flows
freely from exhaust.
O-rings throttle valve dislodged from
seat inlet valve.
1. Pour air tool lubricating oil into air inlet
as per instructions.
2. Operate tool in short bursts of forward and/or reversing
rotation where applicable.
3. Tap motor housing gently with plastic mallet.
4. Disconnect supply. Free motor by rotating drive shank
manually where applicable.
5. If tool remains jammed, return to service center.
O-rings throttle valve dislodged from
seat inlet valve.
Tool will not shut off.
Have a qualified technician replace the O-ring
Excessive drain on the air line. Moisture or
restriction in the air pipe. Incorrect size or type
of hose connectors.
