Adjusting the fastening torque
1
012795
The fastening torque can be adjusted in 16 steps by turning
the adjusting ring so that the graduations are aligned with the
arrow on the tool body. The fastening torque is minimum
when the number 1 is aligned with the arrow, and maximum
when the number 16 is aligned with the arrow.
Before the 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.
