8.1 General maintenance information8.1 General maintenance information
The operator must ensure compliance with the stipulated time limits. This also applies if the
maintenance activities are included in the operator’s internal maintenance schedules.
The gear unit could be damaged if the stipulated time limits for maintenance and servicing
are not observed.
The time limits stipulated in the maintenance schedule are largely dependent on the condi-
tions of use of the gear unit. For this reason, it is only possible to state average time limits
here. These refer to the following conditions of use:
• Daily operating time 24 h
• Duty cycle "ED" 100%
• Gear unit input speed 1500rpm
• Permissible average oil temperature (Page85).
WARNING
Danger to life due to live system
Working on a gear unit while it is in operation is hazardous and can result in potentially
fatal injuries.
Always shut down the gear unit and any oil supply system (whether separate or mounted
on the gear unit) before you carry out any work. Take measures to prevent the accidental
restarting of the drive assembly. Display a warning notice that clearly states that work is
being carried out on the gear unit.
