TORQUE ADJUSTMENT
See Figure 10.
When using the drill-driver for various driving applications,
it becomes necessary to increase or decrease the torque
in order to help prevent the possibility of damaging screw
heads, threads, workpiece, etc. In general, torque intensity
should correspond to the screw diameter. If the torque is
too high or the screws too small, the screws may be dam-
aged or broken.
The torque is adjusted by rotating the torque adjustment
ring.
The torque is greater when the torque adjustment ring is
set on a higher setting. The torque is less when the torque
adjustment ring is set on a lower setting.
The proper setting depends on the type of material and the
size of screw you are using.
