starting. The vacuum cleaner starts automatically
when the machine is switched on.
Switch on the machine and apply the core drill bit to
the material to be worked.
Drill with uniform pressure. Do not overload the ma-
chine. Check with the control lamp 4.
After the drilling is completed, switch off the drill and
the extraction device.

With the gear selector 5, two speed ranges can be se-
lected. Approximate speeds are given in the table be-
low.

the left, right or below on the drill head. In this manner,
fatigue-free and secure working positions are
achieved.
When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
