SYMPTOM
The tool runs at normal
speed, but loses power
under load.
The tool runs slowly. The
air flows slightly from the
exhaust.
MAINTENANCE & STORAGE
1. Lubricate the air mini die grinder daily by dripping a few drops of air tool oil into
the air inlet.
2. Do not use worn or damaged accessories.
3. A loss of power or erratic action may be due to the following:
a) Excessive drain on the air line; moisture or restriction in the air pipe; incorrect
size or type of hose connectors. To remedy these situations, verify the air supply
and follow instructions.
b) Grit or gum deposits in the air-powered mini die grinder may also reduce
performance. If the air-powered mini die grinder has an air strainer (located in the
area of the air inlet), remove the strainer and clean it.
4. When the air mini die grinder is not in use, disconnect it from the air supply, clean
it, and store it in a safe, dry, and childproof location.
STORAGE
If it is necessary to store the tool for an extended period of time, apply a generous
amount of lubrication before storing. The tool should be run for approximately 30
seconds in order to ensure that the lubrication is evenly distributed throughout the tool.
The tool should be stored in a clean and dry environment.

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.
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.
