5.2.4 Cleaning the heat exchanger (Option: CS2-X)

Clean the heat exchanger of the oil/air cooler (Option: CS2-X) regularly in order to maintain the
efficiency. Pay attention to the operating instructions of the oil/air cooler.

5.2.5 Oil level

The installation position must comply with the version on the name plate.

WARNING

Risk of burns and injuries

•  Switch off the drive before checking the oil level.
•  Secure the drive against inadvertent switching on, for example with a padlock.
•  Allow the gear unit to cool down. The oil temperature should be between 20 °C and 40 °C.

Checking the oil level

Information

The SAFOMI option requires a different procedure for checking and adjusting the oil level than that
which is described here (see chapter 5.2.5.6 "No-seal adapter for agitators (Option: SAFOMI)").

1.  Shut down the drive.
2.  Make sure to wait for 5 to 10 minutes.
3.  Check the oil level only if the gear unit is at a standstill and if the oil is free from foaming.

– An oil level above the “Max” marking is impermissible and may indicate the ingress of foreign

liquids (e.g. water).



Check the water content of the oil.

– An oil level below the “Min” marking is impermissible and may indicate a leak.

An impermissible oil level may damage the gear unit.

– Find and correct the reason for the incorrect oil level.
– If applicable, correct the oil level or change the oil (see section 5.2.10 "Oil change").

Use the gear oil type stated on the type plate.

– If possible, filling should be carried out via the vent position.

Other filling positions are possible. The specific dimension sheet for the order is definitive.

For the positions of the oil level measuring device, the vent and the oil drain, please refer to the
specific dimension sheet for the order.

For double gear units (Option: WG) and gear units with auxiliary drive (Option: WX) the oil level must
be checked on both gear units. For auxiliary drives with freewheeling couplings the oil level in the
attachment cylinder must also be checked.

Oil level checks and top-ups may be necessary for attached couplings. In this case, the
manufacturer's documentation must be observed.
