CAUTION:
•Always set the speed change lever fully to the correct position. If you operate the tool with the speed change lever positioned halfway between the “I” side and “II” side, the tool may be damaged.
•Do not use the speed change lever while the tool is running. The tool may be damaged.
Adjusting the fastening torque
The fastening torque can be adjusted in 18 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 
marking is aligned with the pointer.
The clutch will slip at various torque levels when set at the number 1 to 5. 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.
NOTE:
•The adjusting ring does not lock when the pointer is positioned only halfway between the graduations.
•Do not operate the tool with the adjusting ring set between the number 5 and the 
marking. The tool may be damaged.
