1.5 Safety for particular activities
1.5.1 Check for transport damage
Transport damage may cause malfunctions of the gear unit, which may cause personal injury. Oil
which escapes due to leaks may cause a slipping hazard.
• Check the packaging and the gear unit for transport damage.
• Do not operate damaged gear units.
1.5.2 Safety information for installation and maintenance
Before starting work on the gear unit disconnect the drive from the power supply and secure it against
accidental switch-on. Allow the gear unit to cool down. Depressurise the cooling circuit lines.
Damaged or defective components, attachment adapters, flanges and covers may have sharp edges.
Wear work gloves and work clothing.
1.6 Hazards
1.6.1 Hazards when lifting
Persons may be injured by falling or swinging gear units. Therefore also observe the following
information:
• Cordon off a wide area around the hazard area. Take care that there is adequate space to avoid
swinging loads.
• Never stand under suspended loads.
• Use adequately dimensioned means of transport which are suitable for the purpose. The weight of
the gear unit can be obtained from the type plate.
• Gear units may only be transported with shackles and lifting straps/chains at an angle of 90° to 70°
to the horizontal. Do not use the eye bolts on the motor for lifting if a motor is fitted to the gear unit.
The eye bolts are not designed for lifting the motor with heavy attachments. Pay attention to the
section 3.1 "Transporting the gear unit".
1.6.2 Hazards due to rotating parts
Rotating parts cause a risk of entanglement. Therefore provide a contact guard. In addition to shafts,
this also applies to fans as well as drives and drive elements such as belt drives, chain drives, shrink
discs and couplings.
For test operation do not switch on the drive without an installed drive element or secure the parallel
key.
Take possible run-on of the machine into consideration for the design of protective guards.
