TROUBLESHOOTING

The following chart lists common operating system issues and solutions. Please read
it carefully, and follow all instructions closely.
WARNING: 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 follow this warning
may result in serious personal injury.
Disconnect the tool from the air supply before making any adjustments.
Repairs must be performed by a qualified service technician.
PROBABLE CAUSE
 Motor parts are worn.
 The cam clutch is worn or
sticking due to insufficient
lubrication.
 Dirt particles have gotten
jammed in the motor.
 The power regulator is in the
closed position.
 The air flow is blocked by
dirt.
 The compressor is not strong
enough to operate the tool.
 One or more of the motor
vanes is stuck due to
material build-up.
 The throttle valve O-rings
have dislodged from the seat
in the inlet valve.
CORRECTIVE ACTION
 Lubricate the clutch housing.
 Check for excess clutch oil. Clutch cases should only be
filled halfway. Overfilling may cause drag on high-speed
clutch parts. A typical oiled/lubricated die grinder
requires 1⁄2 oz (15 ml) of oil.
GREASE/LUBRICATION NOTE: Heat usually indicates
insufficient grease in the chamber. Harsh operating
conditions may require more frequent lubrication.
 Check the air inlet filter for blockage.
 Pour air tool lubricating oil into the air inlet, as per
instructions.
 Operate the tool in short bursts, quickly reversing
rotation back and forth, where applicable.
 Repeat the previous steps as needed.
 Use the tool with a more powerful compressor.
 Apply air tool lubricating oil into the air inlet.
 Operate the tool in short bursts, quickly reversing
rotation back and forth, where applicable.
 Tap the motor housing gently with a plastic mallet.
 Disconnect the die grinder from the air supply. Free the
motor by rotating the drive shank manually, where
applicable
 Replace the O-rings.
