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 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 3/8" 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.
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 the forward/reverse switch to the right for forward or the left 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.
Air Motor Lubrication
To maintain the maximum performance of the air tool, it must be lubricated
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.
2. Turn the tool upside down and while depressing the trigger, add 4-6
drops of air tool oil or SAE10 nondetergent oil into the air inlet. NOTE:
Depressing the trigger helps circulate oil in the air motor.
