Operation
1. Install a standard 1/4” Air Connector (not included) to the Air Inlet (15). First
wrap the threaded portion of the 1/4” air connector with pipe thread seal tape
before threading it into the Air Inlet (15). Tighten securely.
2. Attach a standard quick connector (not included) to your 3/8” i.d. air pressure
source hose. Then attach the air hose to the Air Ratchet Wrench.
NOTE: If you are not using an automatic in-line oiler, add a few drops of pneumatic
oil to the Air Inlet (15) before attaching the air hose. Add a few more drops of oil
after every hour of continual use.
2. Set the air pressure regulator of your air compressor at 90 psi.
WARNING: Do not exceed the recommended pressure of 90 psi. Damage to your
tool, and possible personal injury may result.
3. 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.
4. Select the appropriate size 1/4” square drive impact socket (not included) for
your needs. Push and snap the socket onto the Ratchet Anvil (42). Caution:
Use only impact sockets. Standard sockets are not strong enough.
5. Set the direction of the Air Impact Wrench to “F” (forward) or “R” (reverse).
Please see photo. By rotating the Reverse Button (38) to the right, you are
setting the tool to operate FORWARD.
NOTE: In this booklet, “FORWARD” refers to
clockwise rotation, and “REVERSE” refers to
counterclockwise rotation. 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 opposite
of this standard.
