The fastening torque can be adjusted in 21 levels by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum fas-
tening torque at 1 and maximum torque at 21.
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 applica-
tion. The following shows the rough guide of the rela-
tionship between the screw size and graduation.
