Machine Elements; Intended Use; Tool Specifications; Noise/Vibration Information - Bosch GBH 7-46 DE PROFESSIONAL Bedienungsanleitung

Use suitable detectors to determine if util-
ity lines are hidden in the work area or call
the local utility company for assistance.
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
handles, when performing an operation
where the tool insert can run into hidden
wiring or its own mains cable. Contact with
a "live" wire can make metal parts of the power
tool "live" and lead to an electric shock.
