The fastening torque can be adjusted in 17 steps by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum
fastening torque at 1 and maximum torque at
marking.
The clutch will slip at various torque levels when set at
the number 1 to 16. The clutch does not work 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.
The following shows the rough guide of the relationship
between the screw size and graduation.
