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 trigger down and put one teaspoon of air tool
oil in the air inlet (use SAE #10 weight oil if air tool oil
is not available). Holding the trigger 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.
*Failure to lubricate the tool at the air inlet will void your
warranty.
Air Supply
Recommended Air Compressor: 3/4 HP tank for intermit-
tent 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.
Set torque regulator, see chart, to set the desired setting
to avoid over tightening and possible damage. Forward
and reverse direction are controlled by pushing the
button noted. Depress the trigger to operate tool.
Impact wrench sockets and accessories must be
used with this tool. Do not use hand sockets and
accessories.
Any excess oil in the motor is immediately
expelled from the exhaust port. Always di-
rect exhaust port away from people or
objects.
