Accident Prevention
Before putting the machine into operation, read
through these operating instructions completely and
observe the safety instructions contained therein as
well as those in the enclosed booklet on general
safety instructions for electro-tools.
If the mains cable is damaged while working, pull
the mains plug immediately.
Never work with a damaged mains cable.
Wear protective glasses, hearing protection, pro-
tective gloves and sturdy shoes.
For safety reasons, work only with the auxiliary
handle 12 mounted.
Do not work with materials containing asbestos.
Do not carry the machine by the cable.
The mains receptacles in the working area must be
protected by a residual current circuit breaker (RC).
For the attachment of identification markings on the
machine, do not drill into the housing. The protec-
tive insulation would be shorted. Use stickers.
When the drill unexpectedly jams, the machine
kicks back. Therefore, always take a secure stance
and hold the machine firmly with both hands.
