OPERATION
Always turn off the air supply, drain hose of air pressure and
detach tool from air supply before installing, removing or adjust-
ing any part or accessory on this tool, or before performing any
maintenance on this tool.
This impact wrench has a 4 position power dial located on the
bottom of the tool. Position 1 is the lowest power setting and
position 4 is the highest power setting. Adjust as necessary. Also
located at the rear of the tool is the directional switch. Rotate
clockwise for forward operation. Rotate counter clockwise for
reverse operation.
Soak rusted nuts in penetrating oil and break rust seal before
removing with impact wrench. Do not use impact wrench beyond
rated capacity as this will drastically reduce tool life.
NOTE: Actual torque on a fastener is directly related to joint
hardness, tool speed, condition of socket and the time the tool
is allowed to impact. Use the simplest possible tool-to-socket
hook up. Every connection absorbs energy and reduces power.

NOTE: During operation, safety goggles must always be worn to
guard against flying debris (users and bystanders).

AIR INLET
POWER DIAL
AIR SUPPLY
Tools operate on a wide range of air pressures. It is
recommended that air pressure measures 90 psig at the tool
with the trigger fully depressed and no load applied to the tool.
Higher pressure (over 90 psig; 6.2 bar) raises performance
beyond the rated capacity of the tool, which will shorten tool life
and could cause injury.
Always use clean, dry air. Dust, corrosive fumes and/or water in
the air line will cause damage to the tool. Drain the water from
air lines and compressor prior to running tool. Clean the air inlet
filter screen weekly. The recommended hookup procedure can
be viewed in the below figure.
The air inlet used for connecting air supply has standard
1/2" NPT. Line pressure should be increased to compensate for
unusually long air hoses (over 25 feet). Minimum hose diameter
should be 3/4" I.D. and fittings should have the same inside
dimensions and be tightly secured.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the
air line, moisture or restrictions in air pipes or the use of hose
connections of improper size or poor conditions may reduce
air supply. Grit or gum deposits in the tool may cut power and
may be corrected by cleaning the air strainer and flushing out
the tool with gum solvent oil or an equal mixture of SAE #10 and
kerosene. If outside conditions are in order, disconnect tool from
hose and take tool to your nearest authorized service center.
LUBRICATION & MAINTENANCE
Lubricate the air motor daily with high quality air tool oil. If no air
line oiler is used, run 1/2 oz. of oil through the tool. The oil can
be squirted into the tool air inlet or into the hose at the nearest
connection to the air supply, then run the tool. A rust inhibitive
oil is acceptable for air tools.
After an air tool has been lubricated, oil will discharge through
the exhaust port during the first few seconds of operation. The
exhaust port must be covered with a towel before applying air
pressure to prevent serious injury.
