Hook
006251
The hook is convenient for temporarily hanging the tool. This can be installed
on either side of the tool.
2
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.
1
The proper fastening torque may differ depending upon the kind or size of the
006255
screw/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 point of the driver bit in the screw head.
Apply forward pressure to the tool to the extent that the bit will not slip off the
M14
screw and turn the tool on to start operation.
NOTE:
• Use the proper bit for the head of the screw/bolt that you wish to use.
(M14)
• When fastening screw M8 or smaller, carefully adjust pressure on the
switch trigger so that the screw is not damaged.
(M12)
• Hold the tool pointed straight at the screw.
• If you tighten the screw for a time longer than shown in the figures, the
(M10)
screw or the point of the driver bit may be overstressed, stripped,
damaged, etc. Before starting your job, always perform a test operation
(M8)
to determine the proper fastening time for your screw.

The fastening torque is affected by a wide variety of factors including the fol-
( S)
lowing. After fastening, always check the torque with a torque wrench.
1. When the battery cartridge is discharged almost completely, voltage will
006257
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 reduc-
tion in the fastening torque.

4. The manner of holding the tool or the material of driving position to be
(M8)
fastened will affect the torque.
5. Operating the tool at low speed will cause a reduction in the fastening
torque.

(S)
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.
