Note
The oil must be warm because insufficient viscosity caused by oil that is too cold impairs
correct emptying.
If necessary, run the gearbox for 15 to 30 minutes to become warm.
8.2.5.2 Draining the oil
Observe the symbols in the diagrams of the Mounting positions (Page 84):
Procedure
1. Switch off the power supply to the drive component.
2. Unscrew the vent plug.
3. Place a suitable and sufficiently large receptacle underneath the oil drain plug.
4. Remove the oil drain plug. Drain all the oil into the receptacle.
5. Check the state of the sealing ring on the sealing element. If the sealing ring is damaged,
replace the sealing element with a new one.
6. After draining the oil, seal the gearbox immediately using the sealing element.
You have now drained the oil from the gearbox.
8.2.5.3 Flushing the gearbox when changing between incompatible oils
Impermissible mixing of oils leads to damage
Residual quantities of original oil can impair the specific properties of the new oil.
A flushing process is required with biodegradable and physiologically safe oils.
The residual corrosion protection oil must amount to no more than 1% of the operating oil
