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.
• 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 spray. For example Alfra BIO 4000, prod. No. 21040.
• Push the button MOTOR ON to start the motor.
• To switch off the machine proceed in reverse order, MOTOR OFF and then MAGNET 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 process, cutter draws back with running motor.
• Remove chips and core after each drilling.
Remove chips with Chip-Remover. Do not touch with bare hands. Danger of injury!
