To begin using the tool:
1. As a standard practice, drain water from the air
compressor tank and air lines prior to use each day
(reference your compressor operators manual for
detailed instructions).
2. Install a 1/4" NPT male plug into the air inlet port on the
tool (see Figure B). Note: Use Teflon® Tape on all
threaded connections.
3. Turn on the air compressor and allow it to build up
pressure.
4. Adjust the air compressor's regulator or the supply line
regulator to 90 PSI.
5. Adjust the torque on the impact wrench by pushing in
and turning the torque regulator knob clockwise to the
desired torque setting (1 = minimum torque/ 4 =
maximum torque). Set the torque regulator knob to 4
(maximum setting) to remove nuts. NOTE: Do not use the air impact wrench to set torque. Always use a
torque wrench to set torque.
6. Attach the desired 1/2" square drive impact socket.
Always use impact-type sockets and extensions that are designed for impact wrenches.
Hand tool sockets will shatter and potentially cause personal injury and/or property damage.
Do not use sockets with excessive wear to the input or output drives. Periodically
check the square drive on the impact wrench. Make sure the socket, extension bar, or other attachment is
securely fitted before operating tool.
When loosening fasteners first ensure that there is sufficient clearance behind the tool
to avoid hand entrapment. The tool will move away from the threaded joint as the nut/bolt is loosened and
rides up the thread, moving the tool with it. Make sure hands are kept away from the sockets during tool
use.
Securely fit the socket or attachment to the impact wrench. Inspect anvil and retaining
ring of tool prior to use. Missing or damaged items should be replaced before use.
Ensure that the forward/reverse switch is in the correct position for tightening or loos-
ening the fastener.
7. Connect the tool to the air hose quick coupler. NOTE: It is recommended that a whip hose with a swivel
(not included) be used to prevent twisting, kinking and excessive wear to the air hose (ref. item "F" in
figure A for recommended connections).
8. Select the tool rotation direction. Push the forward/reverse switch to the left for forward or the right for
reverse.
9. Press the trigger to operate the tool and release the trigger to stop the tool.
Disconnect the tool from the air supply before lubricating or changing sockets.
