Adjusting the fastening torque
The fastening torque can be adjusted in 16 steps by turning
the adjusting ring so that its graduations are aligned with the
pointer on the tool body.
First, slide the action mode change lever to the position of
symbol.
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 16. Before actual opera-
tion, drive a trial screw into your material or a piece of dupli-
cate material to determine which torque level is required for a
particular application.
CAUTION:
• The adjusting ring does not lock when the pointer is
positioned only halfway between the graduations.
