NOTE:
• When fastening screw M8 or smaller, carefully
adjust pressure on the switch trigger so that the
screw is not damaged.
• Hold the machine 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 starting your job, always perform a test
operation to determine the proper fastening time for
your screw. When fastening a standard screw in a
steel plate, the proper fastening torque can be
obtained in an extremely short time (approx.
0.1 – 0.2 seconds). Turn the machine off as soon as
the impact sound is heard.
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.
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 machine or the mate-
rial of driving position to be fastened will affect the
torque.
5. Operating the machine at low speed will cause a
reduction in the fastening torque.

MAINTENANCE
CAUTION:
Always be sure that the machine is switched off and
the battery cartridge is removed before carrying out
any work on the machine.
Replacement of carbon brushes (Fig. 11 & 12)
