OPERATION
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 result
otherwise.
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.
1.
Select the appropriate size 1” square drive socket (not included) for your needs.
Push and snap the socket onto the Anvil (13).
NOTE: On this tool the designation “R” refers to forward or clockwise rotation. “L” refers to
reverse or counterclockwise rotation. Always be aware of the direction of the threading of
the fasteners you are working on. While most fasteners install with clockwise rotation, some
threads are intentionally the reverse.
2.
Set the directions of the Air Impact Wrench to Forward (R=right or clockwise) or
Reverse (L=left or counterclockwise) by adjusting the Rotation/Torque Knob (38). You
may control the amount of torque to be applied by selecting any of the 3 torque settings
(1=low, 2=medium, 3=high).
NOTE: The actual torque delivered at each of the 3 torque settings will depend on the air
pressure supplied to the tool. We suggest that you test the actual torque by tightening a nut
or bolt at each setting, then observing the resultant torque by using a mechanical torque
wrench (not supplied).
3.
If installing a nut or bolt, set it as tight as possible by hand.
4. Place and push on a appropriate size impact socket onto Anvil (13) and place the
Impact Socket (not included) over the fastener.
5. Grip the Air Impact Wrench tightly with both hands, and squeeze the Trigger (36).
The tool will operate and tighten the fastener.
