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
than the removal of spot-welded joints from sheet-
metal structures.
Disconnect compressed-air supply when changing
from one bit to another (VARIO MATIC or cutter).
Wear goggles and protective gloves when working
with your VARIO DRILL.
Never point your VARIO DRILL at yourself or any
other person.
The valued sound pressure level of the VARIO DRILL
is typically 84 dB. The sound level while working with it
may be in excess of such value; therefore, it is recom-
mended to wear ear plugs.
Check cutter blades and tips for breaks or wear.
If necessary, change cutter tool.
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
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
hair protection.
Make sure your VARIO DRILL is completely dis-
connected when cleaning or greasing it.
Protect the machine against falling down. Do not drop
the machine.
Your VARIO DRILL is not insulated against contact
with electric current !
Do not use your VARIO DRILL in an atmosphere
where there is the risk of explosion!
