• Switch off drive unit.
Secure the drive unit to prevent it from being started up unintentionally.
Attach a warning notice to the start switch!
• In the case of gear units fitted with cooling coil or water oilcoolers, close the stop valves on the water

• Start the gear unit and allow it to run briefly (5 to 10 minutes) approx. every 3 weeks (during a shutdown
period no longer than 6 months).
• Treat the gear unit with preservative, see items 7.3.1 and 7.3.2 (before a shutdown period exceeding
6 months).

service oil up to a point just below the air filter.
7.3.1.2 Interior preservation with preservative agent
Before longer shutdown periods gear units with forced lubrication systems, oil-circulation cooling and/or
noncontacting shaft seals should be filled with preservative agent and run without load.
