drops of Pneumatic Tool Oil to the airline
connection before use. Add a few drops
more after each hour of continual use.
2. Connect the air hose to the air inlet of the tool.
3. Push and snap socket (not included) onto the Anvil.
4. The Impact Wrench can be used in either
Forward or Reverse direction.
a. For Models 68423, 68424 and 68425, turn the
Regulator Knob at the back of the housing to the
left. NOTE: There are three torque settings for the
Forward direction.
For Reverse, turn the Regulator Knob to the right.
NOTE: There is one torque setting
for the Reverse direction.
b. For Model 68429, turn the Regulator Knob under
the Main Handle to the desired Forward speed.

5. To tighten, place the socket over
the nut you wish to tighten.
6. Hold the handle rmly and place other hand on
top of Housing. Then gently squeeze the Trigger.

9. If tool requires more force to accomplish task in
Forward or Reverse setting, verify that the tool
receives sufcient, unobstructed airow (CFM) and
increase the pressure (PSI) output of regulator up to
maximum air pressure rating of tool.
CAUTION! TO PREVENT TOOL AND ACCESSORY
FAILURE, RESULTING IN INJURY:
Do not exceed tool’s maximum air pressure rating
(90 PSI).
If tool still does not have sufcient force at
maximum pressure and sufcient airow,
then a larger tool may be required.
When the nut is tightened or
loosened, release the Trigger.
10. 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, and apply a thin coat of tool oil.
Then store the tool indoors out of children’s reach.
