4 FUNCTIONS OF ELECTRONIC
CONTROL
4-1. Overload Detecting Function
WARNING
●
Don't touch the cutter even if the Drill Motor
stops temporarily.
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.
4-2. Lateral-Shifting Detection Function
This function stops the Drill Motor when lateral
shifting of the Magnet base is detected.
As this function comes into action, the lamp will blink
in orange.
To continue operation, turn OFF the Magnet Switch
and, after confirming the drilling position, turn ON
the Magnet Switch again, and turn ON the Drill
Motor switch to start rotation of the Drill Motor.
4-3. Re-Start Prevention Function
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.
4-4. Magnet Interlocking Function
If the magnet is disconnected, the lamp will blink in
red and the Drill Motor will not revolve.
When the Magnet fails the Drill Motor will not start
revolving. To repair defective Magnet, please contact
sales agent through which you have purchased your
machine or an authorized dealer near you.
5 MACHINE SETUP
WARNING
●
When setting up machine, turn off the Magnet
Switch and disconnect the power supply plug
from power source.
5-1. Mounting Parts
Mount the Side Handle on the Drill Motor.
5-2. Using Cutter
CAUTION
●
Use One-Touch type cutters only.
●
For better workability and safety, do not use
worn or damaged cutters.
5-3. Combination of Cutter and Pilot Pin
CAUTION
●
Do not use any other combinations than those
shown in the compatibility table.
Use a Pilot Pin appropriate for the cutter. (Fig.9)
A Pilot Pin to be used varies depending on the cutter
type, diameter, length (depth). A wrong combination
of cutter and Pilot Pin would not allow slug to be
ejected at the end of drilling and/or prevent Cutting
Oil from reaching the cutting point, resulting in
cutting tool damage.
