Gear units – Manual with installation instructions
12 B 1000 en-3921
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.
• Only lift the gear units by the eye bolts which are provided. The eye bolts must be fully screwed in.
Only pull on the eye bolts vertically, never cross-wise or at an angle. Only use the eye bolts to lift
the gear unit without other components. The eye bolts are not designed for lifting the gear unit with
attachments. Use the eye bolts on both the gear unit and the motor to lift a geared motor.
1.6.2 Hazards due to rotating parts
Rotating parts cause a risk of entanglement. This may lead to severe injuries such as crushing or
strangling.
• Provide contact protection. In addition to shafts, this also applies to fans as well as drives and
driven elements such as belt drives, chain drives, shrink discs and couplings. Take possible run-on
of the machine into consideration for the design of protective devices.
• Do not operate the drive without covers or hoods.
• Secure the drive to prevent activation during installation and maintenance work.
• For test operation do not switch on the drive without an installed driven element or secure the
motor shaft key.
• Also observe the safety information in the operating and installation instructions provided by
manufacturers of components supplied.
