Operating Instructions

Description

Impact wrenches are air tools designed
for removing and installing nuts and
bolts. Impact wrenches have different
impact mechanism types such as
rocking dog, pin clutch and twin
hammer (double jumbo).

The rocking dog and pin clutch types
are used as general purpose tools by
DIY’ers and hobbyists. Twin hammer
wrenches are for use by the
professional in tire shops, assembly line
applications and for removing high
torque bolts.

ADVERTENCIA

Operation (Cont.)

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.
Follow the outlined procedures and refer
to parts manual for tool features.
Campbell Hausfeld air tool oil
(ST127000AV) 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 Campbell
Hausfeld 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 (Refer to replacement
parts manual for tool features). 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. See the enclosed yellow flyer.

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
(Refer to replacement parts list for
tool features).

3. Squeeze approximately 1 oz. of
Campbell Hausfeld 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.

SPEED ADJUSTMENT

The impact wrench should never be
used to set torque. Use a torque
wrench to set the torque. All models
are equipped with regulators for speed
adjustment (Refer to parts manual for
tool features).

To remove lugs or bolts, set the
regulator to the maximum setting.
When installing, always use a torque
wrench to attain the proper torque of
the lugs or bolts.

When re-

assembling be
careful not to overtighten. Bolts may
fail or cause a hazardous condition. Be
sure to set the regulator to the
minimum setting then use a torque
wrench to set torque.

AIR TOOL SET-UP

PLEASE REFER TO AIR TOOL AND SPRAY
GUN SET-UP (IN170102AV) FOR AIR

SYSTEM HOOK-UP INSTRUCTIONS.
NOTE: It is not recommended to install a

quick coupler between the tool and the
whip hose.

Using fittings or air hoses which are too

!

WARNING

small can create a pressure drop and
reduce the power of the tool. For 3/8,
1/2 and 3/4” impact wrenches use 3/8”
(I.D.) fittings with 1/4” NPT threads.
Most compressors are shipped with a
short, 1/4” I.D. hose. For proper
performance and more convenience,
use a 3/8” I.D. hose. Hoses longer than
50 feet should have a 1/2” I.D.

For 1” impact wrenches use 1/2” (I.D.)
fittings with 1/2” NPT threads and a
1/2” I.D. hose. Hoses longer than 50
feet should have a 1” I.D.

Never carry a tool

by the hose or pull
the hose to move the tool or a
compressor. Keep hoses away from
heat, oil and sharp edges. Replace any
hose that is damaged, weak or worn.

Storage

The impact wrench must be lubricated
before storing. Follow the air motor
lubrication instructions with an
exception to step 4. Only run the
impact wrench for 2 to 3 seconds
instead of 20 to 30 seconds because
more oil needs to remain in the impact
wrench when storing.
