Adjusting the fastening torque
Fig.5
When you wish to drive machine screws, wood screws,
hex bolts, etc. with the predetermined torque, adjusting
the fastening torque as follows.
1. First remove the battery cartridge from the tool.
2. Loosen the screws securing the light cover.
3. Rotate the ring in the front of the tool by hand so
that a hole can be seen below the ring.
4. Place the battery cartridge in place and pull the
switch trigger. Release it so that the adjusting ring
rotates and becomes visible in the hole. And then
remove the battery cartridge.

5. Use an optional adjusting grip to adjust the
fastening torque. Insert the pin of the adjusting
grip into the hole in the front of the tool. And then,
turn the adjusting grip clockwise to set a greater
fastening torque, and counterclockwise to set a
smaller fastening torque.
6. Align the yellow line with your desired number on
the fastening torque scale.
7. Insert the battery cartridge and be sure that a
fastening torque has been set up by using a
fastening torque tester.
8. Tighten the screws to secure the light cover and
then rotate the ring in front of the tool until the
ring is locked.
NOTE:
Numbers on the fastening torque scale is a
•
guideline to set up your desired fastening torque.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before carrying out
any work on the tool.
Selecting correct socket or screw bit
There are different types of sockets or bits for some
models depending on applications. Choose and install a
correct socket or bit for your application.
Installing or removing socket

Use the tool within the limits of fastening capacity. If you
use the tool beyond the limits, the clutch does not work.
And the tool cannot deliver enough fastening torque.
NOTE:
The revolution angle means the angle which a
•
screw/bolt revolves when the tool attains to 100 %
from 50 % of desired torque.
Use of a low temperature conditioned battery
•
cartridge may sometimes give warning for battery
cartridge capacity by warning lamp and beeper
which makes the tool stop immediately. In this
case, the range of fastening capacity may be
inferior to those shown in the above even if a
charged battery cartridge is used.
