Operation (Fig. I)
Danger posed by rotating parts.
There is a risk of injury.
Â
Never grab rotating parts! When the
¾
motor is running, keep hands and
fingers away from the work area.
Risk of injury
Persons with pacemakers or other
¾
such equipment may operate the
core drilling machine with permanent
magnet system only following prior
consent from a doctor.
Danger posed by electric current.
Prior to first use, check the plug and
¾
cable for damage.
When working on walls and ceilings,
¾
secure the drilling unit with the safety
harness.
MKB 35 COMFORT
▸
Plug in the mains plug.
▸
Insert the core drill into the tool holder [12] on
the motor's work spindle.
▸
Check the tool is clamped in firmly and with
positional accuracy (Fig. II).
The lever [4] is currently pointed in an upward
3
direction.
The switchable permanent magnet is deactivated
3
so the machine can be positioned.
Slight magnetic preloading simplifies the aligning
3
of the machine on vertical walls or in overhead
positions.
▸
Push the lever downwards to the stop.
Ensure that the safety tab [6] audibly latches
in (Fig. III, 1 ).
▸
Once the sensor LED lights up green or flashes
red, the motor can be activated via the operating
panel [5] by pressing the button MOTOR I [10].

WARNING!
WARNING!
WARNING!
CAUTION!
▸
Turning the star handle [1] moves the motor and
the rotating drill slowly towards the workpiece.
Ensure sufficient cooling for the drilling process.
▸
Once drilling operations are over, move the
motor away from the workpiece by turning the
star handle.
▸
Deactivate the motor with the
button MOTOR O [9] on the operating panel [5].
▸
Once the motor has come to a complete stand-
still, remove shavings and other drill residues.
▸
To deactivate the permanent magnet, press the
black safety tab [6] inwards with the ball of the
thumb (Fig. III, 2 ).
▸
Pull the lever [4] upwards (Fig. III, 3 ).
▸
Lastly, clean the magnetic surface of shavings
and other adhesive residues.
Magnetic sensor LED [2] on the hous-
ing
On the machine's housing there is a magnetic sensor
LED which indicates the operating condition of the
machine and the adhesion of the magnets.

EMERGENCY MOTOR STOP
Emergency Motor Stop
The core drilling machine has an auto-
matic emergency shutdown facility for
the motor. If the magnet is forced away
from the ferromagnetic surface when
working with the motor running – e.g.
due to overloading, vibrations or other
causes – an air gap emerges under the
magnet. Once the magnet is released
from the surface, the motor is automat-
ically deactivated and the LED of the
magnetic sensor lights up red continu-
ously.
The motor is not decelerated, however.
