Start-up
You receive a completely assembled magnetic core drilling machine and detailed operating manual. Please check
the condition of the goods on receipt for any transport damage, and make sure the delivery is complete. Otherwise
contact the manufacturer or distributor immediately.
Always read the operating manual before using the device for the first time!
1. First check cable and connector for damages, then plug in the power plug.
2. Insert the annular cutter into the tool holder on the working spindle of the motor and check the rigid and precise
clamping of the tool.
3. Press the switch MAGNET ON (1) to activate the magnet and ensure holding of the drill stand.
 Secure the drilling machine by means of a safety chain when working on walls and ceilings. During this work we
recommend using a coolant spray.
4. Switch the motor on by operating the switch MOTOR ON (3).
5. Slowly guide the motor and the rotating cutter to the tool by turning the star handle. Take special care of
sufficient cooling during the drilling process.
6. Once the drilling operation is completed move the motor upwards by turning the star handle. Switch the motor
off by pressing the red button MOTOR OFF (4) on the control panel.
7. After the motor has come to a complete standstill remove swarf and the remaing drill cuttings.
8. Operate the switch Magnet OFF (2) to deactivate the magnet.
9. Now clean the magnetic surface and remove swarf or any other adhering residues.
Working with Annular Cutters
 Push centring and ejecting 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 centring and ejecting 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 process, cutter draws back with running motor.
 Remove chips and core after each drilling.
