Working safely with this ma-
chine is possible only when the
operating and safety information
are read completely and the in-
structions contained therein are
strictly followed. In addition, the
general safety notes in the enclosed booklet
must be observed. Before using for the first
time, ask for a practical demonstration.
■
Wear hearing protection.
■
Wear safety glasses and sturdy shoes.
■
If the mains cable is damaged or cut through
while working, do not touch the cable but im-
mediately pull the mains plug. Never use the
machine with a damaged cable.
■
Connect machines that are used in the open
via a residual current device (RCD) with an ac-
tuating current of 30 mA maximum. Use only
extension cables that are approved for outdoor
use.
■
Use appropriate detectors to determine if
utility lines are hidden in the work area or
call the local utility company for assist-
ance.
Contact with electric lines can lead to fire and
electric shock. Damaging a gas line can lead
to explosion. Penetrating a water line causes
property damage or may cause an electric
shock.
■
Hold the power tool only by the insulated
gripping surfaces, when performing an op-
eration where the cutting tool may run into
hidden wiring or its own cord.
Contact with a “live” wire will make exposed
metal parts of the tool “live” and shock the op-
erator.
■
Always direct the cable to the rear away from
the machine.
■
Insert the mains plug only when the machine is
switched off.
■
Use the machine only with the auxiliary han-
dle 5.
■
When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
■
Always switch the machine off and wait until it
has come to a standstill before placing it down.
■
Never allow children to use the machine.
■
Bosch is only able to ensure perfect operation
of the machine if the original accessories in-
tended for it are used.
