Adjusting the fastening torque (Fig. 7 & 8)
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 adjust ring rotates and
becomes visible in the hole. And then remove the bat-
tery cartridge.
5. Use an optional adjust grip to adjust the fastening
torque. Insert the pin of the adjust grip into the hole in
the front of the tool. And then, turn the adjust grip
clockwise to set a greater fastening torque, and coun-
terclockwise 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 fasten-
ing torque has been set up by using a fastening torque
tester.
8. Rotate the ring in front of the tool and then tighten the
screw to secure the ring.
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 bat-
tery 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 mod-

rect socket or bit for your application.
Installing or removing socket (Fig. 9)
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

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
Limits of fastening capacity (Fig. 11, 12, 13, 14,

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.
