Obligations of the user

• The operator must ensure that everyone carrying out work on the gear unit has read and understood
these instructions and is adhering to them in every point in order to:
─ avoid injury or damage.
─ ensure the safety and reliability of the unit.
─ avoid disruptions and environmental damage through incorrect use.
• During transport, assembly, installation, dismantling, operation and maintenance of the unit, the
relevant safety and environmental regulations must be complied with at all times.
• The gear unit must be operated, maintained and/or repaired only by authorised, properly trained and
qualified personnel.
• The outside of the gear unit must not be cleaned with high­pressure cleaning equipment.
• All work must be carried out with great care and with due regard to safety.
All work on the gear unit must be carried out only when it is not in operation.
The drive unit must be secured against being switched on accidentally (e.g. by locking
the key switch or removing the fuses from the power supply). A notice should be
attached to the start switch stating clearly that work is in progress.
• No electrical welding work must be done at all on the drive.
The drives must not be used as an earthing point for welding operations. Toothed parts and bearings
may be irreparably damaged by welding.
• A potential equalisation in accordance with the applying regulations and/or directives must be carried
out, if it is not possible to ensure, that voltages possibly occurring can be equalised by way of the
complete machinery, the machine frame, or the like. To this purpose free threaded holes on the gear
unit must be used.
If no threaded holes for earth connection are available on the gear unit, other appropriate measures
must be taken. This work must always be done by electrotechnical specialists.
If any inexplicable changes are noticed during operation of the gear unit, such as an
important increase in temperature or unusual noises, the drive assembly must be
switched off immediately.
Rotating drive components such as couplings, gearwheels, belt drives etc. must be
protected against accidental contact.
When the gear unit is incorporated in plant or machinery, the manufacturer of such
plant or machinery must ensure that the contents of these instructions are
incorporated in his own instructions.
