1. If the tool stalls while tightening, DO NOT raise the outlet pressure of the air

compressor above 90 PSI.

2. When the nut has been tightened, remove the tool and socket. Do not overtighten.

3. If available, check the recommended torque specifications for the nut. You should

use a torque wrench to torque the nut after using the impact wrench.

Loosening

1.Attach the correct size socket to the anvil.

2.Set the compressor's pressure regulator to 90 PSI. Do not set the compressor's

outlet regulator above 90 PSI.

compressor.

When the nut is moved, stop the tool by releasing the trigger and remove the tool from

the nut. Remove the nut from the socket if needed.
