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.
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.

Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening

time.

NOTE:
Hold the tool pointed straight at the bolt or nut.
•
Excessive fastening torque may damage the
•
(S)
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.
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.

Fastening time
Failure to use the correct size socket will cause
a reduction in the fastening torque.
A worn socket (wear on the hex end or square
end) will cause a reduction in the fastening
torque.
Even though the torque coefficient and the
class of bolt are the same, the proper fastening
torque will differ according to the diameter of
