2.� Obligation of contractor
The contractor is obliged to ensure that all measures
geared towards the prevention of accidents, industrial
diseases, labor-related health risks are taken and mea-
sures towards making the workplace fit for people to
work in are carried out.
The contractor is bound to ensure that all electrical
equipment and operating material is set up, modified
and maintained by skilled electricians only or under the
guidance and supervision of a skilled electrician in ac-
cordance with electrical engineering principles.
Furthermore, the contractor must ensure that all elec-
trical equipment and operating material is operated in
keeping with electrical engineering principles.
If a piece of electrical equipment or operating material
is found to be defective, i.e. it does not or no longer
complies with electrical engineering principles, the con-
tractor must ensure that the fault is rectified immedi-
ately and, in the event that imminent danger exists, also
ensure that the electrical equipment or the electrical
operating material is not used.
2.4 Safety instructions
Before starting up, connecting and operating Bosch
products it is absolutely essential that the operating in-
structions/owner’s manual and, in particular, the safety
instructions are studied carefully. By doing so you can
eradicate any uncertainties in handling Bosch products
and thus associated safety risks upfront; something
which is in the interests of your own safety and will ulti-
mately help avoid damage to the device. When a Bosch
product is handed over to another person, not only the
operating instructions but also the safety instructions
and information on its designated use must be handed
over to the person.
