Operating Instructions
Do not use any type of
reactive gases, including, but
not limited to, oxygen and
combustible gases, as a power source.
Use filtered, lubricated, regulated
compressed air only. Use of a reactive
gas instead of compressed air may
cause the tool to explode which will
cause death or serious personal injury.
Use only a pressure-regulated
compressed air source to limit
the air pressure supplied to
the tool. The regulated pressure must
not exceed 90 psi. If the regulator fails,
the pressure delivered to the tool must
not exceed 200 psi. The tool could
explode which will cause death or
serious personal injury.
c . Do not exceed any pressure rating of
any component in the system .

Proper lubrication is the owner’s
responsibility . Failure to lubricate the air
tool properly will dramatically shorten
the life of the tool and will void the
warranty .
This impact
wrench requires
lubrication before the initial use and
before and after each additional use.
Impact wrenches require lubrication
throughout the life of the tool and
must be lubricated in two separate
areas: the air motor and the impact
mechanism . Air tool oil is recommended
because this oil cleans, lubricates and
inhibits rust all in one step .
aIr MoTor lUbrICaTIon
The motor must be lubricated daily . An
air motor cannot be oiled too often .
Disconnect the
impact wrench from
the air supply before lubricating.
1 . Disconnect the impact wrench from
the air supply .
2 . Turn the impact wrench upside
down .
3 . While pulling the trigger, squeeze
approximately a 1/4 oz . of airtool
oil in the air inlet . Then, push the
forward and reverse button in both
directions .
After an air tool
has been lubricated,
oil will discharge through the exhaust
port during the first few seconds of
operation. Thus, THE EXHAUST PORT
MUST BE COVERED WITH A TOWEL
before applying air pressure. FAILURE
TO COVER THE EXHAUST PORT CAN
RESULT IN SERIOUS INJURY.
4 . Connect the impact wrench to the
air supply and cover the exhaust port
with a towel . Run the impact wrench
in both the forward and reverse
directions for 20 to 30 seconds . Oil
will discharge from the exhaust port
when air pressure is applied .
IMpaCT MECHanIsM lUbrICaTIon
Lubricate the impact mechanism
monthly .
Disconnect the
impact wrench from
the air supply before lubricating.
1 . Disconnect the impact wrench from
the air supply .
2 . Remove the slotted screw or allen
head screw from the oil port hole .
3 . Squeeze approximately 1 oz . of air
tool oil in the oil port hole . Replace
the screw .
4 . Reconnect the air supply to the
impact wrench and run for 20 to 30
seconds . Lubricate the entire impact
mechanism by rotating the tool
upside down and sideways while
running the tool .
5 . Remove the screw and hold the oil
port hole over a suitable container
to allow excess oil to drain .
Sometimes triggering the tool when
dumping the oils helps to force out
the excess oil .
6 . If the oil is dirty, repeat the
procedure above until the oil comes
out clear . Install the screw and
tighten . The residual oil remaining
in the impact mechanism chamber
is all that is needed for proper
lubrication .
rECoMMEnDED HooKUp
The illustration below shows the
recommended hookup for the tool .
1 . The air compressor
must be able to
maintain a minimum
of 60 psi when the
tool is being used . An inadequate air
supply can cause a loss of power and
inconsistent driving .
