6. If the Impact Wrench cannot loosen the nut, DO NOT raise the outlet pressure of the air
compressor.
7. If the Impact Wrench’s Air Regulator is set on a low setting, you may raise the setting and
try again. If the Impact Wrench’s Air Regulator is already set on the “4” setting, do not continue
attempts to loosen the nut with the Impact Wrench. Use other appropriate tools and methods to
loosen the nut.
8. When the nut is removed, stop the Impact Wrench by releasing the Trigger and remove the
Impact Wrench from the nut. Remove the nut from the socket if needed.
Tightening
The working torque of the Impact Wrench is 250 feet/lbs. Make sure the nut or bolt you are
using the Impact Wrench to tighten can withstand the rated torque.
1. Tighten the nut on as far as you can by hand.
2. Place the socket on the nut. Press the Reverse Valve forward so it protrudes out the front
of the Housing. Press the Trigger to start the Impact Wrench.
3. If the Impact Wrench stalls while tightening, DO NOT raise the outlet pressure of the air
compressor above 90 PSI.
4. If the Impact Wrench’s Air Regulator is set on a low setting, it may be raised before you try
again. If the nut will not tighten at the maximum setting, do not continue attampts to tighten the
nut. Use other appropriate tools and methods to tighten the nut.
5. When the nut has been tightened, remove the Impact Wrench and socket. Do not over-
tighten.
6. If available, check the recommended torque specifications for the nut. You should use a
torque wrench to torque the nut after using the Impact Wrench.
Maintenance
The Impact Wrench is best operated with an airline oiler. If you are using the Impact Wrench
without an airline oiler, perform the following maintenance:
Disconnect the Impact Wrench from the air hose. Apply a few drops of pneumatic
tool oil through the air line before each use, or every hour if used continuously.
Apply a few drops of oil to the Trigger mechanism. Work the Trigger a few times to
lubricate.
Note: Do not use detergent oil or additives as these lubri-
cants will cause accelerated wear to the tool’s seals.
