The fastening torque can be adjusted in 16 steps by
turning the adjusting ring so that its graduations are
aligned with the arrow on the tool body. The fastening
torque is minimum when the number 1 is aligned with the
arrow, and maximum when the number 16 is aligned with
the arrow.
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.
