DISPOSAL
At the end of the useful life of the OEMTOOLS Air Die Grinder, dispose of
the components according to all state, federal, and local regulations.
PURPOSE
The 24406 1/4” Air Die Grinder features a composite body for comfort and is
designed for deburring, sanding, polishing, carving and other various jobs.
PRODUCT SPECIFICATIONS
Collet Size: 1/4”
Free Speed: 22,000 RPM
Air Consumption: 3.4 CFM
Weight: 1.50 Lbs. (0.7 kg)
Air Inlet Thread
Size: 1/4” Drive
Recommended
Air Pressure: 90 Psi
Length: 7.50” (190 mm)
Exhaust: Rear 360 Degrees
WARNING
Ensure the air supply is clean and does not exceed 90 Psi while operating
the Air Die Grinder. Excessive wear will result if air pressure is too high
and/or you use unclean air. This can shorten the product life and may be
dangerous causing damage and/or personal injury.
OPERATING INSTRUCTIONS
WARNING
Ensure you read, understand and apply safety instructions before use.
1. Always inspect, maintain and operate in accordance with ANSI safety
code for portable air tools (ANSI B186.1) and other local safety codes
and regulations.
2. Do not operate this tool over 90 Psi air pressure.
3. Always disconnect this tool from the air supply before installing,
adjusting or removing any accessory from this tool or before
performing maintenance.
4. Do not carry any air tool by the hose. Keep air hose away from heat
and sharp objects.
5. Continuous use of vibrating air tools by susceptible users may cause
damage to hands.
6. Always lubricate and maintain the tool in safe operating condition.
7. Only use accessories which are specifically designed for use with an
Air Die Grinder.
8. Connect the Air Die Grinder to the air hose.
AIR SUPPLY
Ensure that the Air Die Grinder air valve (or trigger) is in the “off” position
before connecting to the air supply. Always use clean dry air as excessive
moisture will lower the available torque and rust the interior moving parts.
Make sure all hoses and fittings are of the recommended size and be
sure the units are not used with less than or more than the recommended
pressure of the tool (90 Psi).
LUBRICATION
Proper lubrication of this air tool is critical to the operation and life of the
unit. Units can be severely damaged or have excessive wear placed on
working parts if not lubricated. We recommend the use of air tool oil or
3-in-1 machine oil which is available at most auto parts locations. The
tool should be lubricated each time it is used. During daily prolonged use,
lube heavily 3 or 4 times during the day.
WARNING
Any excess oil in the motor is immediately expelled from the exhaust port.
Always direct exhaust port away from people or objects.
MAINTENANCE
WARNING
Disconnect the Air Die Grinder from air supply before changing
accessories, servicing or performing maintenance.
1. Replace or repair damaged parts. Use genuine parts only. Unauthorized
parts may be dangerous and will invalidate the warranty.
2. If the air system does not have an oiler then lubricate the Air Die
Grinder daily with a few drops of air tool oil into the air inlet.
3. Blow out air line to clear it of accumulated dirt and moisture.
4. Connect tool and operate tool to allow oil to be carried to the interior of
the tool.
5. Clean the Air Die Grinder after use.
6. DO NOT use worn or damaged attachments.
