When the Magnet Switch is turned to ON, a lamp on
the side of main body will light up in green.
As the drilling operation load increases, the lamp
will change in color from green to orange to red. In
addition, if the feeding force is further increased,
the lamp will rapidly blink in red and the rotation
of the Drill Motor will slow down and finally stop
temporarily. If the load is released while the lamp is
blinking in red the Drill Motor will resume its rotation.
If the load is not released, the Drill Motor will come
to a complete stop and the lamp will blink in green.
To resume the rotation of the Drill Motor release the
load and turn on the switch of the Drill Motor.

The re-start prevention function comes into play
when power failure is restored that has occurred
during operation.
Thanks to this feature, when a plug that has been
disconnected during operation is re-plugged into the
receptacle or when power failure that has occurred
during operation is restored, the Drill Motor will NOT
restart automatically preventing possible accident
-- although Magnet Switch lamp will come on and
magnetic power restored.
To resume operation, turn ON the Motor Switch on
the rear of the machine to start the Drill Motor.
