MAINTENANCE
• Correct maintenance is crucial to achieve maximum efficiency of your compressor, and to lengthen its operating life.
• It is also important to comply with the maintenance intervals recommended, but it must be remembered that such intervals
are suggested by the manufacturer in the event that the environmental conditions of use of the compressor are optimal (see
“Installation” chapter).
• The maintenance intervals can therefore be reduced depending on the environmental conditions in which the compressor
operates.
• The oil used is FSN Original Oil, the use of a different oil does not guarantee perfect efficiency and compliance with the
maintenance intervals.
• The maintenance operations described in the table below and on the following pages must be carried out by authorised
staff.
