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 a screw.
To remove, loosen the screw 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 part
on the upper side of the button, it is not locked
completely. Insert it fully until the red part 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 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.
• Excessive fastening torque may damage the
bolt/nut or socket. Before starting your job,
always perform a test operation to determine the
proper fastening time for your bolt or nut.
• 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.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
