Operate the shift knob to change the rotational speed. Move the shift knob in the direction of the arrow. (See Fig. 21 and 22)
When the shift knob is set to “LOW”, the drill rotates at a low speed. When set to “HIGH”, the drill rotates at a high speed.
CAUTION:
●When changing the rotational speed with the shift knob, confirm that the switch is off. Changing the speed while the motor is rotating will damage the gears.
●When a large force is required for operation (operations indicated in the following chart) set the shift knob to “LOW”. If “HIGH” is set and the unit is used, it may cause the motor to burn out or malfunction prematurely.
