INSTALLING/REMoVING BATTERy pACK
See Figure 2, page 9.
 To install: lock the switch trigger and insert the battery
pack.

snap in place and that battery pack is secured in the
product before beginning operation.
 To remove: lock the switch trigger and depress latches.
INSTALLING AND REMoVING SoCKETS
See Figure 3, page 9.
Use only sockets designed for impact wrenches. Always
select the correct size impact 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 detent pin locks
it into place.
 To remove the socket, pull it away from the anvil.

CAUTIoN:
The metal surface may become hot during use. Avoid
contact with it to avoid possible burn injury.

opERATIoN
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. While per-
forming the test, make note of the speed selection.
 Hold the tool pointed straight at the nut or bolt.
 Depress the switch and fasten for the proper fastening
 Remove the impact wrench from the nut or bolt.
 Check the torque with a torque wrench.
IMpACT TIME
Many variables exist that will cause the available torque of
the fastener to vary considerably. The optimum impact time
is approximately 6 seconds.
NoTE: Using a universal joint or extension bar may reduce
the fastening force of the impact wrench and require longer
fastening time.

time.
NOTICE:
Do not use this tool to install lug nuts on wheels without
a torque limiting device. Doing so could result in galled
or broken lugs.
NOTICE:
After the head of a nut or bolt has seated, additional im-
pacting will increase the chance of shearing bolts, nuts,
sockets or tearing into wood.
