speed or "1" side for low speed. Be sure that the speed
change lever is set to the correct position before
operation. Use the right speed for your job.
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 "1" side and "2" side, the tool may be
damaged.
Do not use the speed change lever while the tool

the pointer, and maximum when the
aligned with the pointer.
The clutch will slip at various torque levels when set at
the number 1 to 21. 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:
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.
