The fastening torque can be adjusted in 20 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

The clutch will slip at various torque levels when set at
the number 1 to 19. The clutch is designed not to slip at
the marking.
Before actual operation, drive a trial screw into your
