2.2. General safety information

• When installing or removing the product, never
work alone in rooms and shafts. A second person
must always be present.
• The product must always be switched off before
any work is performed on it (assembly, disman-
tling, maintenance, installation). The product
must be disconnected from the electrical system
and secured against being switched on again. All
rotating parts must have come to a stop.
• The person operating the product must notify his
or her supervisor immediately should any defects
or irregularities occur.
• It is of vital importance that the system be shut
down immediately by the operator if any prob-
lems arise which may endanger safety of person-
nel. Problems of this kind include:
• Failure of the safety or control devices
• Damage to important parts
• Damage to electrical equipment, cables, and
insulation.
• Tools and other objects should be kept in a place
reserved for them so that they can be found
quickly.
• Sufficient ventilation must be provided in en-
closed rooms.
• When welding or working with electronic devices,
make sure there is no risk of explosion.
• Only use lashing equipment which is legally de-
fined as such and officially approved.
• The lashing equipment must be kept safely
and must be suitable for the conditions of use
(weather, hooking device, load, etc).
• Mobile equipment for lifting loads should be used
in such a way that it always remains stable during
operation.
• When using mobile equipment for lifting
non-guided loads, take action to prevent tipping,
sliding etc.
• Measures should be taken to ensure that no
person is ever directly beneath a suspended
load. Furthermore, it is also prohibited to move
suspended loads over workplaces where people
are present.
• If mobile equipment is used for lifting loads, a
second person should be present to coordinate
32
the procedure, if required (for example, if the
operator's field of vision is blocked).
• The load to be lifted must be transported in such
a manner that nobody can be injured in the event
of a power outage. Additionally, when working
outdoors, such procedures must be stopped im-
mediately if weather conditions worsen.
These instructions must be strictly observed.
Non-observance can result in injury or substan-
tial material damage.
