OPERATION
WARNING:
Battery tools are always in operating condition. Lock the
switch when not in use or carrying at your side, when
installing or removing the battery pack, and when installing
or removing sockets.
INSTALLING AND REMOVING SOCKETS
See Figure 3, page 9.
Use only sockets designed for impact wrenches. Always
select the correct size impact rated socket for nuts and
bolts.
CAUTION:
Using the wrong size socket may damage the nut or
bolt and cause the fastening torque to be inaccurate or
inconsistent.
 Remove the battery pack.
 Push the socket onto the anvil until the friction ring locks
it into place.
 To remove the socket, pull it away from the anvil.
OPERATING THE IMPACT WRENCH
See Figures 4 - 5, page 9.
CAUTION:
The metal surface may become hot during use. Avoid
contact with it to avoid possible burn injury.
Proper fastening torque may be determined by the kind of
bolt, the size of the bolt or the material or the workpiece. It
is helpful to perform a test operation to determine the proper

fastening time for the nut or bolt you are using.
 Hold the tool pointed straight at the nut or bolt.
 Depress the switch and fasten for the proper fastening
time.
 Remove the impact wrench from the nut or bolt.
 Check the torque with a torque wrench.
NOTICE:
Do not use this tool to install lug nuts on wheels without
a torque limiting device. Doing so may result in galled
or broken lugs.
IMPACT TIME
Many variables exist that will cause the available torque of
the fastener to vary. The optimum impact time is approxi-
mately 6 seconds.
NOTE: Using a universal joint or extension bar may reduce
the fastening force of the impact wrench and require longer
fastening time.
NOTICE:
After the head of a nut or bolt has seated, additional
impacting will increase the chance of shearing bolts,
nuts, sockets or tearing into wood.
