The Craftsman 1/2" Professional Impact Wrench is
designed to operate on 90 PSIG. Lower pressure (below
90 PSI) will reduce performance of the tool, while higher
air pressure (over 90 PSI) raises the performance of the
tool beyond its rated capacity and could cause serious
damage to tool and user.
The tool features a built in regulator with reverse having
maximum power and forward having 3 positions. The
three forward positions are 1,2 and 3, with 3 being the
maximum torque output and 1 being the least amount
of torque output (figure 2 ).

To operate the tool:
° Connect the tool to the air hose
° Adjust the air compressor regulator to 90 PSI. This
tool operates at 90 PSI. Use of pressure, higher than
90 PSI at the tool, may cause injury to the user or
damage to the tool.
° Depress the elongated throttle lever to operate the
tool. The speed of the tool can be varied by teasing
the trigger.
° To stop tool, release the throttle
Lubrication
An in-line filter-regulator-lubricator (fig 1) is recommended
as it increases tool life and keeps the tool in sustained
operation. The in-line lubricator should be regularly
checked and filled with air tool oil. Proper adjustment of
the in-line lubricator is performed by placing a sheet of
paper next to the tools exhaust ports and holding the
throttle open approximately 30 seconds. The lubricator is
properly set when a light stain of oil collects on the paper.
Excessive amounts of oil should be avoided.
In the event that it becomes necessary to store the tool for
an extended period of time (overnight, weekend, etc.), it
should receive a generous amount of lubrication through
the air inlet (fig 3). The tool should be run for
approximately 30 seconds to ensure oil has been evenly
distributed throughout the tool. The tool should be stored
in a clean and dry environment.
Recommended lubricants: Use air tool oil or any other
high grade turbine oil containing moisture absorbent, rust
inhibitors, metal wetting agents and an EP (extreme
pressure) additive. (See Fig. 3 for location/air inlet).
To lubricate the air tool manually:
• Disconnect the tool from the air supply
• Depress the throttle trigger and place several
drops of air tool oil into the air inlet.(Figure 3)
• Connect the tool to the air supply and run for 30
seconds. This will allow the oil to be distributed
throughout the tool motor. The excess oil will be
expelled through the tool exhaust.
This procedure is recommended for both before and
after each use of the tool.
