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 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 coun-
terclockwise to set a smaller fastening torque.
6. Align the edge of the adjusting ring 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. 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 bat-
