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

BEFORE MAINTAINING THE MACHINE ALWAYS PERFORM THE FOLLOWING:

 

Press the machine automatic stop button

 (do not use the emergency button).

 

Power the machine off by means of the wall outer switch.

 

Close the line cock.

 

Make sure that no compressed air is inside the oil separator tank.

 

Remove fairing and/ or panels.
