When using the gear unit please specifically observe the following:
● Do not make any modifications to the gear unit which go beyond the permissible handling
described in these operating instructions. This also applies to safety features designed to
prevent accidental contact.
● Only ever use original spare parts.
Other spare parts are not tested and approved by Flender. Non-approved spare parts may
possibly change the design characteristics of the gear unit and thus impair its active or
passive safety.
Flender will accept no liability or warranty whatsoever for damage occurring as a result of
the use of non-approved spare parts. The same applies to any accessories which were not
supplied by Flender.
If you have any queries, please contact Customer Services (Page 105).
WARNING
Risk of falling
Risk of possible serious injury through falling.
Only walk or stand on the gear unit for maintenance and repair work when it is at a standstill.
Do not walk or stand on shaft ends, protection covers, mounted components or pipes.
Gear unit use
When using the gear unit, please observe the following basic rules:
● Ensure that the gear unit is operationally safe.
● The gear unit should only be operated, maintained or repaired by authorised, trained and
suitably qualified personnel.
● The relevant work safety and environmental protection regulations must be complied with
at all times during transport, assembly, dismantling, operation, maintenance and servicing.
● The outside of the gear unit must not be cleaned using high-pressure cleaning equipment.
● No welding work must be performed on the gear unit or on parts connected to it. The gear
unit and any parts connected to it must not be used as an earthing point for electric-welding
operations. Gearing and rolling-contact bearings might be irreparably damaged by welding.
● Perform potential equalisation in accordance with the applicable regulations and guidelines.
If no threaded holes are available on the gear unit for an earth connection, please take
suitable measures. This work must always be done by specialist electricians.
● In the case of gear units that are operated in combination with electrical machines that
generate current or through which current flows (e.g. motors and generators), take
measures to ensure that no current can flow through the gear unit.
Current flowing through the gear unit can result in irreparable damage to rolling-contact
bearings and gearing. Short circuits, voltage flashovers and deposits of conductive dust, for
example, can all allow current to flow.
Use insulators and earth the gear unit properly.
● When removing any protective devices, retain their fixings safely.
● Removed protective devices must be re-fitted prior to starting up.
