Operating Instructions
www.chpower.com
Do not misuse this
product. Excessive
exposure to vibration, work in awkward
positions, and repetitive work motions
can cause injury to hands and arms.
Stop using any tool if discomfort,
numbness, tingling, or pain occur, and
consult a physician.
SERVICE
a. Tool service must be performed only
by qualified repair personnel.
b. When servicing a tool, use only
identical replacement parts. Use
only authorized parts.
c. Use only the lubricants supplied
with the tool or specified by the
manufacturer.
Do not make any
modifications to
the tool without first obtaining written
approval from Campbell Hausfeld. Do
not use the tool if any shields or guards
are removed or altered. Do not use the
tool as a hammer. Personal injury or
tool damage may occur.
AIR SOURCE
a. Never connect to an air source that
is capable of exceeding 200 psi.
Over pressurizing the tool is able
to result in bursting, abnormal
operation, breakage of the tool or
serious injury to persons. Use only
clean, dry, regulated compressed air
at the rated pressure or within the
rated pressure range as marked on
the tool. Always verify prior to using
the tool that the air source has been
adjusted to the rated air pressure or
within the rated air-pressure range.
b. Never use oxygen, carbon dioxide,
combustible gases or any bottled
gas as an air source for the tool.
Such gases are capable of explosion
and serious injury to persons.
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.

Operating Instructions
LUBRICATION
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.
