6.4 Oil

6.4.1 Oil Changes

The OneGearDrive is supplied with oil ready for operation.
The oil change interval is based on normal operating
conditions and an oil temperature of approximately 80 °C
(176 °F). The oil change interval must be reduced at higher
temperatures (halve it for each 10 K increase in the oil
temperature).
The oil change period in part load is up to 35000 run
hours (for motor characteristics at different loads, see
chapter 8.4 Speed/Torque Characteristics).
The OneGearDrive has drain and filling plugs which make
it possible to change the oil without disassembly.
When changing the oil, inspect and, if necessary, replace
the seals.
Flush the OneGearDrive if the oil grade or oil type is
changed.

See chapter 6.4.4 Changing the Oil.

6.4.2 Oil Grade

The filled oil type is specified on the nameplate. Danfoss
uses food grade oils that comply with NSF H1.
Do not mix different oil types as this may impair the
characteristics of the oil.
Contact Danfoss for further information on oil types.

6.4.3 Oil Volume

The recommended oil quantity for the particular mounting
position is indicated on the motor nameplate. When filling,
ensure that the upper gear unit components are also
lubricated.
