8.0 - 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 am-
bient problems attendant on the installation.
Before doing any work on the unit, the operator must first switch off power to the gear unit
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).
• Befare doing any maintenance work, activate all the safety devices provided and, if necessary, inform per-
sons working in the vicinity. Cordon off the area around the unit and prevent access to any equipment
which, if activated, might be the cause of unexpected health and safety hazard.
• Replace worn components with original spare parts.
• Use the lubricants (oil and grease) recommended by the Manufacturer.
• When working on the gear unit always replace all gaskets and seals with original new anes.
• lf a bearing requires replacement, it is good practice to also replace the other bearing supporting the same
shatt.
• We recommend replacing the lubricating oil atter all maintenance work.
The above instructions are aimed at ensuring efficient and safe operation of the gear unit.
The Manufacturer declines all liability for injury to persons and damage to components due to the use of
non-original spare parts and non-routine work that modifies the safety requirements without the Manufactu-
rer's express prior authorisation.
Refer to the specific spare parts catalogue when ordering spare parts for the gear unit.
Do not dump polluting liquids, worn parts and maintenance waste into the environment.
Dispose of all such materials as specified by applicable legislation.
• Observe the routine inspection and maintenance schedule to ensure the unit's correct opera-
tion and the effectiveness of the explosion protection.
• Always apply fresh Loctite 510 or other produet with similar properties and application range to
all disassembled threads.
• Befare servicing or repairing internal components, allow the gear unit to cool down completely
befare opening the casing so as to avoid bums from parts which are still hot.
• On completion of maintenance work, make sure that all safety measures and equipment have
been applied and reset.
• Clean the gear unit thoroughly atter maintenance and repair work.
• On completion of maintenance, tighten all vent, filler and level plugs to their specified torques
(chart A1).
• On completion of any maintenance work all seals must be refitted and sealed as prescribed.
• Regardless of the type of gear unit, whenever a seal ring is replaced its lips should be smea-
red with a thin layer of grease (Fluorocarbon gel 880 ITP or other produet with similar proper-
ties and application range) befare assembly.
• Use only original spare parts for repairs.
