□
Effectiveness of the shaft seals

Removal from service
•
Switch the drive unit off.
Secure the drive unit to prevent it from being started up unintentionally.
Attach a warning notice to the start switch!
•
In case of gear units fitted with cooling coil or water oilcooler, close the stop valves on the coolingwater
in and outflow pipes. To prevent freezing, drain the water from the cooling coil or the water oilcooler.
•
Start the gear unit and allow it to run briefly (5 to 10 minutes) approx. every 3 weeks (during a shutdown
period no longer than 6 months).
•
Treat the gear unit with preservative agent, see items 7.3.1 and 7.3.2 (before a shutdown period
exceeding 6 months).
7.3.1
Interior preservation for longer disuse
Depending on the type of lubrication and/or shaft sealing, the following types of interior preservation can
be applied.
7.3.1.1 Interior preservation with gear oil
Gear units with splashlubrication systems and contacting shaft seals can be filled with the correct type of
service oil up to a point just below the air filter.
7.3.1.2 Interior preservation with preservative agent
Before longer shutdown periods gear units with force-feedlubrication systems, oilcirculation cooling
and/or noncontacting shaft seals should be filled with preservative agent and run without load.
