MAINTENANCE INSTRUCTIONS
OPERATING INSTRUCTIONS
1. LUBRICATION:
Lubricate the tool daily with a high-quality air tool oil. If no inline oiler is used, run a teaspoon of oil through the tool.
The oil can be added into the tool air inlet or into the hose at the nearest connection to the air supply, then run the tool.
2. TIGHTNESS OF PARTS:
Regularly check whether all connecting parts are fastened securely. Follow this procedure daily before beginning work.
3. STORAGE:
Avoid storing the tool in a location subject to high humidity. If the tool is left unused, the residual moisture inside the
tool can cause rust. Before storing and after operation, oil the tool at the air inlet with a good quality air tool oil and
run it for a short period.
4. REPAIR & SERVICING:
For further operational and handling information or for replacement of parts and components, contact your
Kimball Midwest Sales Representative or Power Tool Repair (371 West Ave. Tallmadge, OH 44278, 330-630-0022).
Users of this tool should review the chemical composition of the work surface and any products used in conjunction
with this tool for any hazardous chemicals prior to engaging in any activity that creates dust and/or microscopic particles.
Users should obtain the Safety Data Sheets for all identified chemicals, either from the manufacturer or their employer,
and proceed to study, understand, and follow all instructions and warnings for exposure to such chemicals.
Some examples of these chemicals are: lead from lead based paints; crystalline silica from bricks, cement and other
masonry products; and arsenic and chromium from chemically treated lumber. A listing of the chemicals can be
obtained at www.oehha.ca.gov under Proposition 65.
In order to reduce their exposure to such chemicals, users should always:
- work in well-ventilated areas.
- wear appropriate safety equipment and PPE that are specifically designed to filter out microscopic particles.
PRODUCT INFORMATION
When unpacking, check the parts diagram and part number listing on page 3 to make sure all parts are included.
BEFORE USE
INTENDED USE OF THE TOOL
This 1/4" Die Grinder is designed as a handheld pneumatic tool used to grind, sand, hone, polish or machine
materials such as metal or plastic. Do not use this tool outside of the designed intent. Never modify the tool
for any other purpose or use.
SPECIFICATIONS
• Extended shaft provides access for hard to reach places
• High speed
• Positive grip body for easy control
• All ball-bearing construction for long tool life
• Lever throttle for positive speed control
• Rear exhaust air flow system
Collet Size: 1/4"
Free Speed: 20,000 RPM
Overall Length: 13" (340mm)
Net Weight: 2.8 Lbs
Motor: 0.42 HP
Air Inlet: 1/4" NPT
Air Hose I.D. Size: 3/8"
Avg. Air Consumption: 4 CFM
Air Pressure: 90 PSI
To Operate The Die Grinder:
1. Use the two wrenches provided to loosen the Collet Nut.
2. Insert the 1/4" diameter shank of a cutting/grinding tool (not included) fully into the collet.
Then, firmly re-tighten the collet nut to lock both the collet and shank in place.
3. Connect the air supply hose to the Die Grinder. Turn on the air compressor, and set its regulator to the
recommended 90 PSI for the Die Grinder.
4. In order to keep the air supply hose out of the way, hang it over your shoulder.
5. IMPORTANT! Grip the Die Grinder firmly with both hands.
6. Trip the safety lever assembly (23) with your finger. Then slowly apply hand pressure to the trigger until the desired
speed is obtained. NOTE: The Die Grinder always turns the tool shank clockwise.
7. With a firm grip on the Die Grinder, lightly apply the cutting/grinding tool to the workpiece, slowly and steadily moving
the cutting/grinding tool to the right and left until you have achieved the desired appearance (finish) on the workpiece.
8. Once the work is completed, release hand pressure on the trigger (23). The safety will automatically
return to its locked position to prevent the trigger from accidentally being activated.
9. Turn off the air compressor. Trip the safety with your finger, and slowly squeeze the trigger to release any
remaining air pressure from the Die Grinder. Then, disconnect the air hose from the tool.
10.Remove the cutting/grinding tool from the Die Grinder. Then, store the tool in a clean,
dry location out of reach of children.

The oil and water extractor should not be mounted on
or near the air compressor.
The temperature of air is greatly increased during
compression. As the air cools down to room
temperature, in the air line, on its way to the air power
tool, the moisture contained in it condenses. Thus, for
maximum effectiveness, the oil and water extractor
should be mounted at some point
in the air supply system where the temperature of the
compressed air in the line is likely to be lowest. Air
lines must be properly drained daily. Each low point in
an air line acts as a water trap. Such points should be
fitted with an easily accessible drain. See diagram
below. Pitch all air lines back towards the compressor
so that condensed moisture will flow back into the air
receiver where it can be drained off.
WARNING
1. The tool shall not be used in potentially explosive atmosphere.
2. Disconnect the air hose before changing or adjusting any inserted tools.
3. Before using tool, please confirm all couplings and plugs are fixed securely. An air hose that is under pressure
may lash out when disconnected and could lead to serious injuries.
4. Prevent loose clothes, long hair or any other personal accessories from coming close to moving parts to
reduce the risk of being caught, trapped or drawn into the rotating spindle.
5. Excessive high air pressure that exceeds the maximum pressure may cause injuries to user or damage to the tool.
6. Exposure to strong vibration for extended time may cause harm to operator.
7. Be aware of the rotation direction before starting the tool to reduce hazardous situations
due to unexpected rotation direction.
8. WATCH YOUR STEP! Leaving excess hose unattended near working area or walk path could result in injury or death.
9. Wearing eye/face protection could reduce the danger to person from high speed splinters
being emitted from the tool or work surface.
10. Wearing correct breathing protection will help avoid inhaling dust or debris from work process
that can be harmful to your health.
11. High sound levels can cause permanent hearing loss. Use hearing protection while operating tool.
12. Depending on the material being processed, there may be a risk of explosion or fire.
Be aware of work surface dangers prior to beginning work.
13. There is a risk of being cut due to high speed rotation. Do not touch high speed rotating tools or attachments.
14. This power tool is not insulated. If contact is made with an electric current, injury may occur.
15. Dust created by sanding, sawing, grinding, drilling and other related activities may expose the
user to dust and/or microscopic particles that may contain chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm.
SAFETY PRECAUTIONS:
Never use the tool for any application for which it was not designed. Never alter or modify the tool or the
components. Improper operation or modification could result in serious injury.
