make sure all parts are included. If any parts are missing or damaged, please call
Harbor Freight Tools at the telephone number on the cover of this manual as soon as

Your Air Impact Wrench comes pre-assembled. To complete preparations for use, follow
the steps shown on the following page. Part numbers shown below identify parts shown
on the part number listing on page 6.
Air Connection
1. Remove the Screen from the Inlet (both included in part 42). You will need an air
hose fitting (sold separately) before you can connect your Impact Wrench to an air
compressor.
2. Attach the air hose fitting to the Inlet and tighten with a wrench.
3. Attach a quick-disconnect coupler (sold separately) to the air hose fitting if desired.
This is a useful accessory as it allows quick-coupling action when using a variety
of tools with the same air compressor.
4. The Impact Wrench is ready for use.
Operation
Frequent but not excessive, lubrication is required for best performance. Oil added
through the airline connection will lubricate internal parts. An automatic airline oiler is
recommended but oil may be added manually before every operation or after about 1 hour
of continuous use. Only a few drops of oil at a time are necessary. Too much oil will collect
inside the tool and be blown out during the exhaust cycle. ONLY USE PNEUMATIC TOOL
OIL. Do not use detergent oil or additives as these lubricants will cause accelerated wear
to the seals in the tool.
Dirt and water in the air supply are major causes of pneumatic tool wear. Use a filter/
oiler for better performance and longer life. The filter must have adequate flow capacity for
the specific application. Consult the manufacturer’s instructions for proper maintenance of
your filter.
The connector on the tool must not hold pressure when the air supply is disconnected.
If the wrong fitting is used, the tool can remain charged with air after being disconnected.
Your Impact Wrench features an air Regulator (37), allowing you to vary the amount of
torque exerted on the nut or bolt you are working on. Setting “1” is the lowest setting, and
is recommended for smaller nuts and bolts. Setting “4” is the highest setting and provides
the most torque and speed.
