Safety rules

The following safety measures should always be taken,
regardless of any additional safety or accident-prevention
rules which might be applicable in each country:
Do not use your VARIO DRILL for purposes other
G
than the removal of spot-welded joints from sheet-

To reduce the risk of breaking to a minimum, do not

use cutter tools other than the genuine VARIO DRILL
cutters.
Never hold workpieces in your hand, but have them
G
clamped instead or make sure their own weight holds
them down to give the correct support.
If you wear long hair, you should use an appropriate
G
hair protection.
Make sure your VARIO DRILL is completely dis-
G
connected when cleaning or greasing it.
