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.
Maintenance table
To verify correct machine operation, perform the followng checks after the first 100 hours of work :
1) Check the oil level : top up with the same type of oil if necessary.
2) Check for proper screw tightening
: in particular the power electric connection screws.
3) Visually check that all fittings seal properly.
4) Check the hours of work and the type of service selected
5) Check room temperature .
