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.
In the work of the save mode (S), avoid the continuous screw-tightening as temperature
of electronic components of the converter switch increases.
