VIBRATION PRECAUTIONS
This tool vibrates during use. Repeated or long-term exposure to vibration
may cause temporary or permanent physical injury, particularly to the
hands, arms and shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an extended period
should first be examined by doctor and then have regular medical
check-ups tonsure medical problems are not being caused or
worsened from use. Pregnant women or people who have impaired
blood circulation to the hand, past hand injuries, nervous system
disorders, diabetes or Raynaud’s Disease should not use this tool.
If you feel any symptoms related to vibration (such as tingling,

PURPOSE
The OEMTOOLS ¼” Air Ratchet has increased power to size and weight
ratio for use in numerous applications, such as the removal of steering
arms, water pumps, brake caliper bolts and alternators. It is particularly
good for hard-to-reach high torque fasteners and work in confined areas
where the patented reactionless design eliminates risk of finger/hand
trapping.
PRODUCT SPECIFICATIONS

WARNING
Ensure the air supply is clean and does not exceed 90 PSI while operating
the Air Ratchet. 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 Ratchet.
8. Connect the Air Ratchet to the air hose.
AIR SUPPLY
Ensure that the Air Ratchet 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).
WARNING
TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Use only clean, dry, regulated, compressed air to power this tool. Do not
use oxygen, carbon dioxide, combustible gases or any other bottled gas
as a power source for this tool.
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 Ratchet 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 Ratchet
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 Ratchet after use.
6. DO NOT use worn or damaged attachments.
