Adjusting the fastening torque
Fig.6
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 lamp 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 edge of the adjusting ring with your
desired number on the fastening torque scale.
7. Align the yellow line with your desired number on
the fastening torque scale.
8. Insert the battery cartridge and be sure that a
fastening torque has been set up by using a
fastening torque tester.
9. Tighten the screws to secure the lamp 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
Fig.8
To install the socket, push it onto the square drive of the
tool with one hand by depressing a pin on the square
drive with another hand until it locks into place. To
remove the socket, simply pull it off depressing the pin on
the square drive.
Installing or removing bit
Fig.9
For tools with retracting sleeve
To install the bit, pull the sleeve in the direction of the
arrow and insert the bit into the sleeve as far as it will go.
Then release the sleeve to secure the bit.
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly.
For tools without retracting sleeve
To install the bit, just insert the bit into the spindle as far
as it will go. To remove the bit, pull the bit out firmly.

OPERATION

Hold the tool firmly and place the socket over the bolt or
nut. Then switch the tool on. When the clutch cuts in, the
motor will stop automatically. Then release the switch
trigger.
NOTE:
Hold the tool with its square drive pointed straight at
•
the bolt or nut, or the bolt or nut will be damaged.
Limits of fastening capacity
Use the tool within the range of the revolution angle up to
360 ﾟ. If you use the tool beyond the upper limit of this
range, the clutch does not work. And the tool cannot
deliver enough fastening torque (LED flickers in red and
green alternatively).
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 fastening capacity may be inferior to the
specification on this manual even if a charged
battery cartridge is used.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes
Fig.10
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
