Operation
1. Install a standard 1/4” Air Connector (not included) to the Air Inlet (36). First
wrap the threaded portion of the 1/4” air connector with pipe thread seal tape
before threading it into the Air Inlet (36). Tighten securely.
2. Attach a standard quick connector (not included) to your 3/8” air pressure
source hose. Then attach the air hose to the Air Impact Wrench.
NOTE: If you are not using an automatic in-line oiler, add a few drops of pneumatic
oil to the Air Inlet (36) before attaching the air hose. Add a few more drops of oil
after every hour of continual use.
3. Set the air pressure regulator on your air compressor at 90 psi.
WARNING: Do not exceed the recommended pressure of 90 psi. Damage to your
tool, and possible personal injury and/or property damage may result.
4. Check the air line and its connections for air leaks. Make note of these, and
repair them before using this tool.
NOTE: Turn off your air compressor and disconnect the air pressure hose before
changing sockets or making any adjustments to this tool. Severe injury or property
damage may otherwise result.
WARNING: This tool generates considerable torque when in use. Always hold the
tool with both hands when using, and brace yourself to resist the torque which will
be delivered to the work piece.
5. Select the appropriate size 3/8” square drive impact socket (not included) for
your needs. Push and snap the socket onto the Anvil (9).
6. Set the direction of the Air Impact
Wrench to “FORWARD” or
“REVERSE”. Please see photo. By
moving the Throttle Lever “Butterfly”
(5) to the right, you are setting the
tool to operate FORWARD. You may
control the amount of torque to be
applied by rotating the Regulator (38)
(See photo next page).
There are
settings from 1 through 8, indicating
increasing torque. Rock the Throttle
Lever “Butterfly” (5) to the left to REVERSE the direction of the tool.
NOTE: In this booklet, “FORWARD” refers to clockwise rotation, and “REVERSE”
refers to counterclockwise rotation of the Anvil (9). Always be aware of the direction
of the threading of the fastener you are working on. While most fasteners install
with clockwise rotation, some threads are intentionally the reverse.
