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.
