6 MAINTENANCE
Maintenance and replacement work must be carried out by expert maintenance technicians trained
in the observance of applicable laws on health and safety at work and the special ambient problems
attendant on the installation. In order to maintain the proper functioning and safety of the gearbox/
gearmotor, we recommend that users have non-routine maintenance performed by the Manufacturer
or an authorised, specialist service centre. Contact the manufacturer’s sales network. Failure to
comply with this requirement during the warranty period automatically invalidates the warranty.
Never improvise repairs.
Before doing any work on the unit, the operator must first switch off power to the gearbox and ensure
that it is out of service, as well as taking all necessary precautions against it being accidentally
switched on again or its parts moving without warning (due to suspended loads or similar external
factors).
Furthermore, all additional environmental safety precautions must be taken (e.g. elimination of
residual gas or dust, etc.).
• Disconnect power to the machine in which the gearbox is installed before commencing any maintenance
work, and secure all switches in the OFF position. All persons performing maintenance must secure the
disconnecting switches for themselves, using personal devices (e.g. padlocks) the keys of which they
must keep with them for the duration of the work.
• Ensure surfaces have cooled before commencing work. If necessary, wear anti-burn safety gloves when
working on gearboxes. Refer to chapter “ALLOWED TEMPERATURE LIMITS” for further details.
• Before commencing any maintenance work, activate all the safety devices provided and, if necessary,
inform persons working in the vicinity. Cordon off the area around the gearbox and prevent access to any
equipment which, if activated, might be the cause of unexpected health and safety hazards.
• Replace worn components with original spare parts.
• Use only recommended lubricants (oil and grease).
• When working on the gearbox, always replace all gaskets and seals with original new ones.
• If a bearing requires replacement, it is good practice to replace the other bearing on the same shaft as
well.
• Change the oil after completing maintenance work.
• If, during work, there is any risk of coming into contact with oils and greases, respect the safety precautions
provided on the manufacturer’s data sheets and use all items of personal protective equipment specified
therein.
If the gearbox is not going to be used for a prolonged period following installation or run-in, it must be
run at least once a month. If this is not possible, the gearbox must be protected against corrosion with a
suitable rust inhibitor, or completely filled with new oil of the type normally utilised for operating duty. (See
the “STORAGE” section in this manual.)
The above instructions are aimed at ensuring the efficient and safe operation of the gearbox.
The manufacturer declines all liability for injury to persons or damage to components due to the use of
non-original spare parts or non-routine work that compromises safety requirements without express prior
authorisation. Refer to the specific spare parts catalogue when ordering spare parts for the gearbox.
