In any case, after 130 kg of gas recovered, a message of maintenance appears on the display - carry out at this
moment the maintenance of the station.

Replace the pump oil after
100/150 hours
of working or at least
every year
even if the station is used occasionally.
The oil's replacement is indispensable also when the presence of contaminating substancies in the oil makes it
turbid; in this case the mechanical parts of the pump may be damaged irreparably.

300 grams
.
