Maintenance
Oil change
Foreword
As mentioned above, oil performs
multiple functions that are crucial
to the smooth operation of the
compressor and, consequently, it is essen-
tial check both its quantity and condition at
the recommended frequency.
Please refer to the speci
fi
c tables for selec-
ting the oil types most suitable to the diffe-
rent operating conditions.
First change of oil
If not otherwise indicated on the speci
fi
c
plate, the compressor is supplied with Ro-
toroil F2 oil.
The
fi
rst oil change and the
fi
rst oil
fi
l-
ter change should take place within 5000
hours or a year.
It is to be noted that expired oil is dange-
rous for the smooth operation of the com-
pressor, hence once the forecast interval
for its change has elapsed, it should be
replaced.
Oil replacement should be done with the
machine off and with warm oil.
To drain oil, wait for the complete depressu-
rization of the compressor, while verifying
that the pressure gauge on the separator
shows that no more pressure exists inside
(Fig.10-pos.1).
Slowly unscrew the
fi
lling plug (Pict.9-pos.
2), while checking for any foam presence.
In case, wait for some minutes until when
the oil demulsi
fi
es.
Open the drain tap (Pict.9-pos.1) and the
plug located on the oil extraction unit (Pict.
10-pos.2) to facilitate oil drain. Let oil
fl
ow in
a suitable case.
Close the drain tap. Fill the oil chamber with
fresh oil until it completely covers oil check
window.
Tightly lock the tap and close the oil extrac-
tion plug.
Start the compressor and let it run for some
minutes, and then stop it. Check the correct
level by means of the speci
fi
c indicator and
fi
ll it up again, if necessary (Fig.9-pos.3).
Using Rotoroil lubricants
It is recommended to use Mattei Rotoroil
Lubricants.
The subsequent changes could be made at
the forecasted intervals.
Should the machine have already worked
for a long period with other oils, and should
lacquers and deposits be present, then it is
recommended to wash with Rotoroil F2/F4
so as to remove all residual impurities.
It is also recommended, when
fi
lling the
machine up with new oil, to replace the oil
fi
lter and the
fi
ltering elements of the sepa-
rator.
