Gear units with oil expansion tank /ET

NOTICE

An oil viscosity above the permitted level of 3500 mm2/s may result in inadequate venting and an insufficient oil filling which could damage the gear unit.
Possible damage to property.
  • Observe the oil viscosity during the filling process.

NOTICE

An oil temperature outside the permitted range during the filling process may cause oil deficiency or oil leakage during operation.
Possible damage to property.
  • The temperature of the oil to be filled must generally be within a temperature range of 10 °C and 40 °C.

Also observe the notes in chapter Procedure for gear units with oil expansion tank /ET.

Thus, a higher minimum filling temperature might be required depending on the selected oil type. Guide values can be found in the following table.
