• Caution (Instruction without symbol)
Substantial material damage can occur. Irreparable
damage is possible!
Safety instructions begin with a signal word and
description of the hazard, followed by the hazard
source and potential consequences, and end with
advice on prevention.
Example:
Beware of rotating parts!
The rotating rotor can crush and sever limbs.
Switch off the product and let the rotor come to
a stop.

2.2 General safety

• 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, dismantling, main-
tenance, installation). The product must be discon-
nected from the electrical system and secured against
being switched on again. All rotating parts must have
come to a stop.
• The operator should inform his/her superior immedi-
ately should any defects or irregularities occur.
• It is of vital importance that the system be shut down
immediately by the operator if any problems arise
which may endanger safety of personnel. Problems of
this kind include:
• Failure of the safety and/or control devices
• Damage to important parts
• Damage to electric installations, cables, and insula-
tion.
• 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 enclosed
rooms.
• When welding or working with electronic devices,
ensure that there is no danger of explosion.
• Only use fastening devices which are legally defined as
such and officially approved.
• The fastening devices should be kept safely and must
be suitable for the conditions of use (weather, hooking
system, load, etc).
• Mobile working apparatus for lifting loads should be
used in a manner that ensures their support stability
during operation.
• When using mobile working apparatus for lifting non-
guided loads, preventive measures should be taken to
avoid tipping and 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 work-
places where people are present.
• If a mobile working apparatus is used for lifting loads, a
second person should be present to coordinate 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 case of a
power outage. Additionally, when working outdoors,
