Adjusting the fastening torque (Fig. 7)
When you wish to drive machine screws, hex bolts, etc.
with the predetermined torque, adjust the fastening torque
as follows.
1. First remove the battery cartridge from the tool.
2. Loosen and remove the screw that secures the ring.
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
the hole becomes visible as illustrated. And then
remove the battery cartridge.
(Fig. 8)
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
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. Rotate the ring in the front of the tool and then tighten
the screw to secure the ring.
NOTE:
• Numbers on the fastening torque scale are a guideline
to set up your desired fastening torque.
