NOTE:
• Use the proper bit for the head of the screw/bolt that
you wish to use.
• Hold the tool pointed straight at the screw.
• If you tighten the screw for a time longer than shown in
the figures, the screw or the point of the driver bit may
be overstressed, stripped, damaged, etc. Before start-
ing your job, always perform a test operation to deter-
mine the proper fastening time for your screw.
The fastening torque is affected by a wide variety of fac-
tors 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.
2. Driver bit or socket bit
Failure to use the correct size driver bit or socket bit
will cause a reduction in the fastening torque.
3. Bolt
• Even though the torque coefficient and the class of
bolt are the same, the proper fastening torque will
differ according to the diameter of bolt.
• Even though the diameters of bolts are the same,
the proper fastening torque will differ according to
the torque coefficient, the class of bolt and the bolt
length.
4. The manner of holding the tool or the material of
driving position to be fastened will affect the torque.

NOTE:
• Use the tool with a fastening torque less than 12.5 Nm.

such as tightening bolt M10 or bolts greater than M10
or removing rusted screws.
