Air Supply
Recommended Air Compressor: 1 HP tank for intermittent
use - 1.5 HP or larger for heavier duty use.
Air hose should be at least 3/8" I.D.
Pipe and fittings between compressor and air hose should
be at least 1/2" nominal size. (5/8 I.D.). Be sure piping is
free of droops and sags where moisture can accumulate.
*The use of air filters and air line lubricators is
recommended.
Operation
Before each use, drain water out of air compressor tank
and condensation from air lines. After clearing air com-
pressor moisture and lubricating tool, connect tool to an air
hose of recommended size. Check air pressure. This tool
operates at a maximum 90 PSI pressure.
The throttle control lever provides instant response when
depressed. The reverse button is located in the ratchet
housing and determines the direction of rotation. When
driving a fastener to the point that the ratchet stalls, further
tightening can be accomplished by operating the air
ratchet in the same manner as a manually operated
ratchet.
Impact wrench sockets and accessories must be
used with this tool. Do not use hand sockets and
accessories.
Lubrication
Air tools require lubrication throughout the life of the tool.
The air motor and bearing uses compressed air to power
the tool. Because moisture in compressed air will rust the
air motor, you must lubricate the motor daily. An inline oiler
is recommended.
To lubricate the air motor manually:
1. Disconnect the tool from the air supply holding it so
the air inlet faces up
2. Hold the throttle lever down and put one drop of air
tool oil in the air inlet (use SAE #10 weight oil if air
tool oil is not available). Holding the throttle lever
down helps circulate oil in the motor.
3. Connect the tool to an air source, cover the exhaust
port with a towel and run for a few seconds.
ANY EXCESS OIL IN THE MOTOR IS IMME-
DIATELY EXPELLED FROM THE EXHAUST
PORT. ALWAYS DIRECT EXHAUST PORT
AWAY FROM PEOPLE OR OBJECTS.
*Failure to lubricate the tool at the air inlet will void
your warranty.
