OPERATION
ADJUSTABLE TORQUE CLUTCH
See Figure 12.
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 should
correspond to the intensity of the screw diameter. If the
torque is too high or the screws too small, the screws may
be damaged 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.
ADJUSTING TORQUE
n Identify the twenty four torque indicator settings located
on the front of the drill.
