9. Oil

9.1 Oil change

The oil in the oil chamber should be changed at least once a year or after 3000 operating hours. (The number of
operating hours can read by means of a CIU XX2 and an R100 remote control.)
If the oil contains more than 20 % of water, the shaft seal may be defective.
Note
If the shaft seal is replaced, the oil must be changed. Check the oil after one week of operation.
Warning
When slackening the screws of the oil chamber, note that pressure may have built up in the
chamber. Do not remove the screws until the pressure has been fully relieved.

9.2 Draining of oil

1. Remove both oil screws (pos. 193) to allow the oil to drain from the chamber into a container.
2. Lay the pump on the side and turn it to empty the oil chamber.
3. Check the oil for impurities.
4. Clean the pump of spilled oil.
Oil, gaskets and metal parts must be disposed of in accordance with local regulations.
