► 1 . Adjusting ring 2. Graduation 3. Arrow
The fastening torque can be adjusted in 22 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
The clutch will slip at various torque levels when set at the number 1 to 21. 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.
NOTE: See the following chart for the relation between the number of torque setting and fastening torque rate.
The fastening torque rate will be different depends on materials. Make a test fastening to get the desired torque
before operation.
