10.1 General notes on maintenance
All maintenance and repair work must be done with care and by duly trained and qualified personnel only.
The following applies to all work in item 10.2:
Switch the gear unit and addon components off.
Secure the drive unit to prevent it from being started up unintentionally.
Attach a warning notice to the start switch.
The periods indicated in table 13 largely depend on the conditions under which the
gear unit is operated. Only average periods can therefore be stated here. These refer
to:
a daily operating time of 24 h
a duty factor "ED" of 100 %
an inputdrive speed of 1500 1/min
an operating temperature of 80 °C (applies to mineral oil)
The operator must ensure that the intervals stated in table 13 are adhered to.
This also applies if the maintenance work is included in the operator’s internal
maintenance schedules.
