ring 3. Graduation 4.
The fastening torque can be adjusted in 20 levels by turning the adjusting ring. Align the
on the tool body. Then, align the graduations with the arrow on the tool body. You can get the minimum fastening
torque at 1 and maximum torque at 20.
Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which
torque level is required for a particular application. The following shows the rough guide of the relationship between
the screw size and graduation.
