4. FUNCTIONS OF ELECTRONIC
CONTROL
4-1. Overload Detecting Function
When overload occurs during drilling operation,
the overload detector puts the following functions
to work. Please note, however, that there may be
cases where the overload detector does not work
properly if power is drawn from an engine generator
with fluctuating output voltage, sometime tool high
and sometime too low.
●
Automatic Feed Rate Control Function
Automatic drill feed starts slowly for the first few
seconds and then it picks up speed automatically to
an appropriate level in terms of cutting load applied
to the cutter. In addition, a cutter diameter factor
is also taken into account for automatic feed rate
control.
●
Automatic Stop Function
Overload to the Drill Motor or feed motor
automatically stops the drill and ongoing feed,
preventing possible damage to the machine and
cutter. However, if a worn or blunt cutter is being
used, it may break.
4-2. Automatic Cycle Stop Function
When drilling operation is complete with the machine
relieved of cutting load, the Drill Motor stops
automatically.
4-3. Limit Switch Function
Even if the automatic cycle stop function fails to
operate and the drill continues to feed down, the
Limit Switch will stop the down-feed near the lower
limit of the stroke and the Drill Motor.
4-4. Lateral-Shifting Detection Function
This function stops drill feed and the Drill Motor
when lateral shifting of the Magnet is detected.
4-5. 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 is restored that has
occurred during operation, the Drill Motor will NOT
restart automatically preventing possible accident --
although Magnet lamp will come on and magnetic
power restored.
To resume operation, turn ON the Motor Switch on
the side of the machine to start the Drill Motor.
4-6. Magnet Interlocking Function
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.
