repair or adjustment. When replacing O-rings or cylinder,
lubricate with air tool oil before assembly.
PROBLEM: Product runs at normal speed but fails
under load.
POSSIBLE CAUSES
■ Motor parts are worn.
■ Cam clutch is worn or sticking due to lack of lubricant.
REMEDIES
■ Lubricate clutch housing.
■ Check for excess clutch oil. Clutch cases need only
be half full. Overfilling can cause drag on high speed
clutch parts, i.e. a typical oiled/lubricated tool requires
14.20 ml (1⁄2 ounce) of oil.

NOTE: Heat usually indicates insufficient grease in
chamber. Severe operating conditions may require
more frequent lubrication.
PROBLEM: Product runs slowly. Air flows slightly
from exhaust.
POSSIBLE CAUSES
■ Motor parts are jammed with dirt particles.
■ Power regulator is in closed position.
■ Air flow is blocked by dirt.
REMEDIES
■ Check air inlet filter for blockage.
■ Pour air tool lubricating oil into air inlet as per
instructions.
■ Operate product in short bursts quickly reversing
rotation back and forth where applicable.
■ Repeat above as needed.
PROBLEM: Product will not run. Air flows freely from
exhaust.
POSSIBLE CAUSE
One or more motor vanes are stuck due to material
build up.
REMEDIES
■ Pour air tool lubricating oil into air inlet.
■ Operate product in short bursts of forward and/or
reverse rotation where applicable.
■ Tap motor housing gently with a plastic mallet.
■ Disconnect the air supply. Free the motor by rotating
drive shank manually where applicable.
