SPEED 1/LOW 2/HIGH 1/LOW 3. MODE DRILL MODE (TORQUE ADJUSTMENT NOT ACTIVE) DRIVE MODE 2/HIGH 1/LOW 2/HIGH HAMMER MODE 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 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. TO DECREASE TORQUE TORQUE ADJUSTMENT RING TO INCREASE TORQUE Fig. 10 15
