Operate the shift knob to change the rotational speed. Move the shift knob in the
direction of the arrow (see Figs. 13 and 14).
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.
