Every 300 Hours: Oil Change (Fig. 10); Every 500 Hours: Drive Belt Tension Check; Routine Maintenance; Every 2 Years - FINI NUAIR NB4 Manual De Instrucciones

ALWAYS replace damaged filter elements.
Do not operate the compressor without the suction filter fitted, as foreign bodies or dust could seriously
damage the inside components.
NOTE: REPLACE FILTERING CARTRIDGE EVERY TWO OIL CHANGES.

4.5 Every 300 hours: oil change (fig. 10)

To proceed with the replacement:
– Remove the cap from the filler plug A, connect the (supplied) drain hose to cock B, and collect the used oil in a bowl.
– Remove the drain hose, screw the cap on the cock B, and fill with new oil through the filler A.
– Top up and change oil when the compressor is hot.
The compressor is delivered with a special semi-synthetic oil (Syntenergy, available by authorized dealers) and which
you should use.
This oil can possibly be replaced with SAE 15W/40 oil or an alternative of the same quality, which will be used for
subsequent refilling.
Never mix different oils.
Do not spoil the environment with used oil: contact the body responsible for correct disposal.

4.6 Every 500 hours: drive belt tension check

Remove upper and rear panels. To check belt tension, apply a 30N/3 kg weight at belt mid-length. Belt flexion should
be about 10 mm (fig.12).
Loosen electric motor nuts. Tension up belt at motor end, taking care to preserve alignment with compressor pulley.
Re-tighten the nuts.

4.7 Routine maintenance

Every 6 months
Clean air radiator and all radiator fins to preserve cooling efficiency and ensure greater machine performance.

Every 2 years

Check and clean suction and delivery valves.
Inspect check valve and change seal (A) (fig.13), if necessary.
In these cases it is recommended to change relevant gaskets.

4.8 Compressor disposal

Dispose of all materials according to prevailing rules.
Always contact special disposal and recycling centres.
