5. Attach the socket (1) of required size to the drive head (2) of the tool
(Fig. B).
6. Place the socket over the nut to be removed or installed.
7. Press the trigger (1) of the tool for rotating operation
(Fig. C).
8. Adjust the regulator knob(1) at the rear end of the tool to control
the speed of the air flow and to adjust the direction of rotation
(forward and reverse) (Fig. D).
9. Verify that the air supply is clean and that air pressure does not exceed 90 PSI while operating the
Air-powered impact wrench.
DO NOT use any additional force upon the wrench in order to remove a nut.
DO NOT allow wrench to free run for an extended period of time as this will shorten its life.
AIR SUPPLY
IMPORTANT: To operate correctly, this tool requires airflow of at least 6.5 Cubic Feet per
Minute(CFM) at 90 Pounds per Square Inch (PSI) at the tool.
Air hose may cause loss in pressure up to 15 psi, requiring a higher compressor output to compensate and
maintain required pressure at the tool.
Check the specifications of your air compressor to be sure that it can support both the CFM and PSI
required by this specific tool.
1. Ensure wrench air valve (or trigger) is in the “off” position before connecting to the air supply.
2. It will require air pressure of 90psi, and air flow according to specification.
3. WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the wrench.
Too high an air pressure and unclean air will shorten the product life due to excessive wear, and may
be dangerous causing damage or personal injury.
4. Drain the air tank daily. Water in the air line will damage the wrench.
5. Clean air inlet filter weekly.
6. Line pressure should be increased to compensate for unusually long air hose. The hose diameter
should be 3/8” I.D.
7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all
connections are secure.
