Operate the shift knob to change the rotational
speed. Move the shift knob in the direction of the
arrow (See Figs. 7 and 8).
When the shift knob is set to “LOW”, the drill

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.
