COMMISSIONING
Your package contains a fully assembled metal core drilling machine and detailed operating instructions.
Upon receiving your delivery, please check its contents for any transport damage and that you received
everything you ordered. Please instantly contact the manufacturer if you encounter any problems.
!
Always read the operation manual before using the device for the first time!
1. First of all, check the cables and connectors for damages.
2. Plug the safety switch connector into a fused mains socket.
3. Before starting the core drilling machine motor, be sure to press the RESET button to activate the
safety switch. Repeat this step every time you pull the mains plug and every time the safety switch
triggers.
4. Activate the solenoid by pressing the associated switch (Solenoid) to ensure that the drill rig reliably
adheres to the workpiece.
• If you are working on non-magnetic materials, please use the ROTABEST Vacubest vacuum
equipment (part no. 18150).
5. Secure Rotabest with a strap when holding the machine vertically up against the wall or ceiling. During
these applications, best practice is to cool the drill bit with a spray (e.g. ALFRA 4000, part no. 21040).
6. Press the green button (Motor) to switch on the drive motor.
7. Repeat the above step to switch the motor off: First of all, press the red button (Motor) to switch off
the motor, then press the Solenoid button to deactivate the solenoid.
Do not use the safety switch as an On/Off switch!
SETTING THE SPEED
The machine features a gear drive of four mechanical gear speeds and a full-wave rectifier.
• First of all, adjust the mechanical setting as appropriate, then use the electronic speed governor to set
the exact speed.
• If possible, opt for the setting with a narrow gear spacing and a high motor speed. This will run the
motor at high torque and protect it against overheating under high loads.
THERMAL PROTECTION
Thermal protection automatically turns off the motor if it overheats. Afterwards, idle the motor at high speed to
let it cool down for about 2 minutes.
