General Operating Instructions
1. WARNING! Use only 3/8” Drive
Impact type sockets (sold separately).
2. If an automatic oiler is not used, add
a few drops of Pneumatic Tool Oil
to the airline connection before use.
Add a few drops more after each
hour of continual use.
3. Push and snap the socket (not
included) onto the Anvil (31).
4. Slide Reverse Valve (9) to the left
for clockwise (forward) rotation.
NOTE: This is a sliding valve that is
connected to Regulator Knob (12).
5. Place the socket over the nut you
wish to tighten.
6. Grip tool firmly with both hands and
gently squeeze Trigger (14).
7. Adjust air flow by turning Air
Regulator Knob from positions 1
through 5. Match up desired number
setting with the recessed dimple.
Position 1 allows the lowest amount
of air flow, and Position 5 the highest.
8. If the tool requires more force to
accomplish task, verify that the tool
receives sufficient, unobstructed
airflow (CFM) and increase the
pressure (PSI) output of the regulator
up to the maximum air pressure
rating of this tool.
9. CAUTION! TO PREVENT TOOL
AND ACCESSORY FAILURE,
RESULTING IN INJURY:
Do not exceed the tool’s maximum
air pressure rating. If tool still does
not have sufficient force at maximum
pressure and sufficient airflow, then a
larger tool may be required.
10. Once nut is tightened, release
Trigger. Turn off the air supply and
disconnect the hose.
11. If available, check the recommended
torque specification for the nut. Use
a torque wrench to tighten the nut
to the proper setting after using the
Impact Wrench.
12. To set Impact Wrench in Reverse,
slide Reverse Valve to the right for
counterclockwise (reverse) rotation.
Then adjust air flow by turning Air
Regulator Knob from positions 1
through 5. Position 1 allows the
lowest amount of air flow, and
Position 5 the highest.
13. WARNING! Before changing the
rotational direction of the tool, release
the Trigger and allow the tool to come
to a complete stop.
14. When the nut is loosened, release
Trigger. Turn off air supply and
disconnect the hose. If needed,
remove the nut from the socket.
15. To prevent accidents, turn off the
tool, detach the air supply, safely
discharge any residual air pressure in
the tool, and release the throttle and/
or turn the switch to its off position
after use. Clean external surfaces of
the tool with clean, dry cloth. Then
store the tool indoors out of children’s
reach.
