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 fastening torque at 1 and maximum torque at
marking.
The clutch will slip at various torque levels when set at the number 1 to 20. 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.
