Changing The Oil (Main Gear Unit) - Siemens FLENDER H3LV Assembly And Operating Instructions Manual

10.2.2 Changing the oil (main gear unit)

As an alternative to the oil­change intervals specified in table 11 (see item 10.1), it is possible to have an
oil sample tested at regular intervals, every 4 weeks, by the technical service of the relevant oil company
and to have it cleared for further use.
If further usability has been confirmed, no oil change will be necessary.
Note
Please observe the separately annexed operating instructions BA 7300 and the notes in item 7.1.
• Drain the oil while the gear unit is still warm, i.e. immediately after stopping the machinery.
NOTICE
Material damage
Risk of damage to the gear unit through incorrect lubrication resulting from mixed oils.
When changing the oil, always re­fill the gear unit with the same type of oil.
Never mix different types of oil and/or oils made by different manufacturers.
The use of synthetic oil is not permissible.
• Place a suitable container under the oil­drain points of the gear­unit housing.
