Removal from service
•
Switch off drive unit.
Secure the drive unit to prevent it from being started up unintentionally.
Attach a warning notice to the start switch!
•
Close the stop valves in the coolant in and outflow pipes (on gear units with oilcooling system only).
In the case of water oilcooler, drain the water. Frost hazard!
•
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, see items 7.3.1 and 7.3.2 (before a shutdown period exceeding
6 months).
7.3.1
Interior preservation during 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 forced lubrication systems, oil circulation cooling and/or
noncontacting shaft seals should be filled with preservative agent and run without load.
