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!
• In the case of gear units fitted with cooling coil or water oil­coolers, close the stop valves on the water
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, see items 7.3.1 and 7.3.2 (before a shut­down period exceeding
6 months).

Depending on the type of lubrication and/or shaft sealing, the following types of interior preservation can
be applied.

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.
