At the same time as the filter change the machine will ask to change the vacuum pump oil
Perform the operations listed below on a routine basis in order to ensure good operation of the
vacuum pump:
M1) Oil top-up.
M2) Oil change.
When topping-up or replacing the pump oil, use only the oil recommended by the
manufacturer. Contact your retailer for information concerning the correct type of oil.

(ref.3, Fig.20A).
NOTE: in order to correctly check the oil level, run the pump for at least 1 minute (running a
vacuum procedure in the hose for 1 minute) so that the oil fluidifies.
