The fastening torque can be adjusted in 17 steps by
turning the adjusting ring so that its graduations are
aligned with the pointer on the tool body. The fastening
torque is minimum when the number 1 is aligned with the
pointer, and maximum when the
with the pointer.
The clutch will slip at various torque levels when set at
the number 1 to 16. The clutch is designed not to slip at
the marking.
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.
