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 may only be operated, maintained and/or repaired by persons qualified for the work
concerned (see "Qualified personnel" on page 3 of this manual).
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.
Secure the drive unit to prevent unintentional switch­on! (e.g. by locking the key
switch or removing the fuses from the power supply). The add­on or separate
oil­supply system must also be stopped, if installed. A notice should be attached to the
start switch stating clearly that work is in progress.
At the same time the complete installation must be without load, so that no danger
occurs during demounting operations (e.g. change of the backstop).
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 directives
must be carried out!
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 specialist
electricians.
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 and/or movable drive components must be fitted with suitable safeguards to
prevent contact.
All add­on parts must satisfy the requirements in Directive 94/9/EC.
Simple electrical means (such as monitoring devices, switches, Pt 100 resistance)
without identification in accordance with Directive 94/9/EC are to be connected
intrinsically safely by suitable isolation amplifiers.
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.
