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 connector (not included) into
the air inlet port on the tool (see Figure 2). 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 butterfly impact wrench by turning the torque regulator knob clockwise to the
desired torque setting (1 = minimum torque/ 8 = maximum torque). Set the torque regulator knob to 8
(maximum setting) to remove nuts. NOTE: Do not use the butterfly impact wrench to set torque. Always
use a torque wrench to set torque.
6. Attach the desired 3/8” square drive impact socket. Use deep sockets in place of extensions when possible.
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.
7. Connect the tool to the air hose quick coupler. NOTE: It is recommended that a whip hose with a swivel
(P012-0079SP - not included) be used to prevent twisting, kinking and excessive wear to the air hose
(ref. item “F” in figure 1 for recommended connections).
8. Select the tool rotation direction. Push or squeeze the forward/reverse lever to the right for forward rotation.
Push or squeeze the forward/reverse lever to the left for reverse rotation.
NOTE: Soak rusted nuts in penetrating oil and break the rust seal before removing with the impact
wrench. If the nut does not start to move in three to five seconds, use a larger size impact wrench.
Do not use this impact wrench beyond the rated capacity.
9. Release the forward/reverse lever to stop the tool.
Disconnect the tool from the air supply before lubricating or changing sockets.

Air Motor Lubrication
To maintain the maximum performance of the air tool, it must be lubricat-
ed each time it is used. Dust, dirt, rust and oil residue will build up inside the
tool and reduce the performance. An in-line oiler is recommended for proper
automatic tool lubrication (see Figure 1). If an in-line oiler is not available, the
tool can be lubricated manually through the inlet port (see Figure 3).
1. Disconnect the air tool from the air supply.
