Installing hook
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
► 1. Groove 2. Hook 3. Screw
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool. To install
the hook, insert it into a groove in the tool housing
on either side and then secure it with two screws. To
remove, loosen the screws and then take it out.
OPERATION
CAUTION:
Always insert the battery cartridge
all the way until it locks in place. If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of
the tool, causing injury to you or someone around
you.
Hold the tool firmly and place the impact socket over
the bolt or nut. Turn the tool on and fasten for the proper
fastening time.
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.

NOTE: Hold the tool pointed straight at the bolt or nut.
NOTE: Excessive fastening torque may damage the
bolt/nut or impact socket. Before starting your job,
always perform a test operation to determine the
proper fastening time for your bolt or nut.
NOTE: If the tool is operated continuously until the
battery cartridge has discharged, allow the tool to rest
for 15 minutes before proceeding with a fresh battery
cartridge.
When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
