1. This impact wrench is rated to 1/2" USS bolt size. Rating will decrease for U-Bolts, Long Cap
Screws, Spring Fasteners and rusted/corroded Fasteners. All of these factors absorb power and
reduce torque capability.
2. Use only impact sockets designed for impact wrenches.
3. Most impact wrenches have high torque capability. Keep a firm grip on the tool at all times. Use
both hands whenever possible. Be physically prepared for the task you will perform.
4. Always use approved eye and ear protection when using air powered tools. If raising dust/debris,
wear a suitable mask. Do not wear loose clothing or jewelry.
5. Always operate tool at a safe distance from yourself and others in the work area. Keep footing and
balance at all times.
6. Make sure work piece is secure to allow safe operation of the tool with both hands. Do not hold the
work piece in your hand, lap or against any part of your body.
7. Make sure trigger is in the "off" position before connecting or disconnecting the tool from air
source. Disconnect tool form air source before changing accessories, performing service and
when not in use.
8. Follow air source manufacturer's directions for connection of regulators, filters and other
accessories to air source. Do not install quick couplers directly at tool air inlet. This causes inlet
failure due to excess weight and vibration. Use a whip hose between tool and quick couplers
9. DO NOT OVERLOAD! Do not force tool. Match tool capacity to work load requirement. Use tool
within its rated capacity and only for its designated purpose. Overloading air tools will cause
premature wear and/or permanent damage of internal and external driver parts and will void
warranty.
10. Inspect hoses and fitting for wear and damage prior to using tool, do not carry or drag tool by the
air hose. Keep air hose free from obstruction, twisting and binding.
Oil tool before each use. 4 to 5 drops of a good grade Air Tool Oil placed in the air inlet is sufficient. Use
proper air pressure and CFM rating listed for this tool.
Drain water from hoses and compressor tank. Water in the air supply line will cause gumming and loss of
power. Clean the air filter on the supply line and flush the tool with gum solvent or a 50/50 min of Air
Tool Oil and kerosene. It may be necessary to disassemble the tool to properly clean and re-lubricate.
Oil Plug is available to add air tool oil after repair or maintenance. (See drawing at right) use 1 ounce Air
Tool Oil. Do not overfill.
Hammer Mechanism Maintenance-(Hammer Cage, Hammer Dog Anvil and Drive Cam).
When cleaning or repairing the tool, be sure to lightly coat the load bearing and mating surfaces with
clean wheel bearing grease or suitable substitute. Do not apply a thick coat of grease to these parts.
This will reduce the torque capability of the tool and will require flushing to regain its power. You may
also run the tool until the excessive grease works its way out.
Test the tool for proper grease periodically by shaking the tool from side. Listen for a metallic rattle. If the
sound is loud and sharp, grease the hammer parts. If it is a dull sound, the lubrication is correct.
