Safety instructions
&
&
~
During drilling operations on walls and ceilings, the metal core drilling machine must be
safeguarded with the included safety chain. The magnetic adhesion is not maintained In case of
a failure of circuit.
The
cut core will be ejected automatically by the ejector pin. The ejector pin could possibly
break in case of improper use.
Only use undamaged power cord and extension cords and regularly check on damages.
Danger
of an electric shock!
Power
supply and voltage details at the device must correspond.
When working
with this device, wear the following protection equipment:
Safety goggles, appropriate footwear, ear protection, hair net
{for long hair), possibly also apron
and safety helmet.
The place
of installation for the magnet foot must be clean and rustfree. Remove lacquer and
filler.
Do not execute any electric welding on the workpiece on which the Metal Core Drilling Machine
is used.
Prior
to all operations mount coolant unit.
Specified conditions
of use
This device is destined to cut material with magnetisable surface with core cutters and twist drills in sheltered
environment for commercial use
in industry and craft. The device is suitable for drilling vertical, horizontal and
overhead.

Description
The magnetic core drilling machine can
be fixed with a switchable electromagnet on ferromagnetic workpieces.
The electromagnet and the motor can be switched on and off wi
th the large buttons of the control panel.
The LED above the front panel shows the operating status of the machine and the adhesive force of the magnet.
A self-adjusting dovetail guide on which the motor
is mounted can be adjusted in height with the star handle or be
locked with a slide. On the back of the machine is the nameplate and an attachment for the enclosed Allen keys.

Switching on and off
• Check connecting line and plug on damages first.
• Push the button MAGNET ON so that the magnet adheres and the grip of the drill stand is ensured.
• Check the display of the signal LED above the control pane
l.
• Push the button MOTOR ON to start the motor.
• To switch the machine off proceed in reverse order, MOTOR OFF and then MAGNET OFF.
• For non-magnetisable materials use the Rotabest Vacubest (Prod.-No. 18150).
• When working on walls and ceilings secure the machine with the safety belt.
At this work we recommend cooling the tool with a coolant spray. For example Alfra 810 4000, prod. No. 21040.

on and insufficient adhesion.
Motor cannot be activated or motor emergency stop.

Motoremergency stop
The core drilling machine has an automatic emergency stop. If the magnet, while working with running motor, is
pushed off the ferromagnetic workpiece by overload, vibrations or other causes and an air gap occurs between
magnetfoot and workpiece, the motor will be deactivated automatically and the magnet-LED is steady red. The
motor though will not be slowed down!
~ A restart of the machine is only possible a~er switching the magnet on and off.
How
to work with annular cutters
• Push ejector pin (center pin) through head of annular cutter.
• Core drills with Weldon shank are tightened with clamping screws (DIN 913) on both clamping surfaces.
• First place annular cutter with ejector pin on a marked centre or marking.
• Set the cutter and spot-drill, until the entire cut edge
is formed as a circle.
• During the drilling process, the cutter should be cooled permanently. Optimal cooling
is possible by internal
cooling with our coolant unit.
• During the drilling process, do not stop the motor. After the drilling process, draw back the cutter with running
motor.
• Remove chips and core after each dril
li ng.
£ Remove chips with chip-remover. Do not touch with bare hands. Danger of Injury!
How
to work with twist drills
• The drill chuck with Weldon shank is only to be used with twist drills up to a diameter of 13 mm.
• Insert drill chuck with MT2 tool holder
in the drill spindle.
• Insert twist drill
in drill chuck and tighten.

Cleaning
Pull plug prior to cleaning. Danger of injury by unintentional switching on.
• Clean the outside of the motor by means of dry compressed air.
• Check connecting lines on damages.
• Clean and grease sliding surfaces regularly.
• Carbon brushes should be replaced after appr. 250 hours runni
ng time.
• After the work is finished we recommend to store the metal core drilling machine in the transport case in a
lying position.
Maintenance and repair
Maintenance, checks and repairs are only to
be made by electronic specialists according to the valid regulations of
the respective country.
8 Onlyuse genuine ALFRA spare parts.
~ Spare part list at the end of this operation manual.
The metal core drilling machine Alfra Rotabest should be serviced after appr. 250 hours running time by our Alfra
workshop or appointed dealers. The Gear oil (Lubcon, Turmogearoil
PE 150 300m!) should be exchanged as well
as the brushes.
