Check the oil level by means of the
graduated dipstick [Fig. 7, Ref. 2]. The level must
always be between the MAX and MIN notches on the
dipstick [Fig. 7 Ref. 1].
6.3 Engine oil and oil filter change
The engine oil sump capacity is 2.3 litres.
Top-ups and filling with engine oil is carried out through
the hole [Fig. 3, Ref. 17].
To change the oil in the oil sump, remove the dipstick
[Fig. 7, Ref. 2] and operate the special extraction pump
[Fig. 3, Ref. 12] after having removed the screw which
functions as plug.
It is recommended to drain the oil when it is still
sufficiently warm to flow easily.
For recommended oils see table "A", Fig. 8.
- The first engine oil change must be carried out after
50 hours of generator operation. For the second
and subsequent oil changes, every 200 hours is
sufficient.
- For more detailed information on engine lubrication,
consult the engine use and maintenance manual
attached to the generator.
- Dispose of the used oil or fuel in an appropriate
manner as they are polluting products.
Take the used engine oil to special collection
centres responsible for disposal.
Avoid contact of engine oil with
the skin. During maintenance operations use gloves
and protective glasses.
In case of contact with engine oil, immediately and
thoroughly wash the affected part with soap and
water.
To replace the engine oil filter cartridge [Fig. 3, Ref.16],
unscrew it from its support, using suitable tools normally
found on the market. Reposition the new cartridge,
taking care to lubricate the rubber ring gasket.
The first replacement must be carried out after 50 hours
of generator operation. For the second and subsequent
replacements, respect an interval of 400 hours.
For further information consult the engine use and
maintenance manual.
For the safety of the engine, use
only original spare parts.
When the operation has been
completed, thoroughly wipe off all oil and fuel from
the engine parts.

6.4 Air filter cleaning
The generators of the IS series have a dry air filter which
prevents foreign bodies from entering the combustion
chamber. For its maintenance it is sufficient to clean the
filtering mass with diesel fuel once a year to remove nay
impurities.
Dispose of the liquids used for air
filter washing in an appropriate manner. Take them
to special collection centres.
6.5 Fuel filter replacement
To guarantee long life and proper functioning of the
engine, it is extremely important to periodically replace
the fuel filter cartridge, respecting the frequency indicated
by the engine manufacturer as listed in the table in
Paragraph 6.15.
This operation is carried out in the following steps:
- Close the fuel cock [Fig. 3, Ref. 24]
- Completely unscrew the ring nut of the support [Fig. 3,
Ref. 13]
- Remove the old cartridge and position the new one.
- For remounting repeat the operations in reverse order.
When the filter has been replaced, bleed the fuel system
carrying out the operations described in Paragraph 4.2.
Avoid contact of the fuel oil with
the skin. During maintenance operations use gloves
and protective glasses.
In case of contact with fuel, immediately and
thoroughly wash the affected part with soap and
water.
completed, thoroughly wipe off all traces of fuel and
take the used cloths to special collection centres.
6.6 Coolant check
Periodically check the coolant level in the closed-circuit
cooling system. The reference index for this check is
printed on the expansion tank [Fig. 3, Ref. 11]. If the level
is insufficient, pour coolant into the expansion tank,
taking care not to exceed the maximum level index.
expansion tank [Fig. 3, Ref. 11] or coolant tank [Fig.
3, Ref. 20] when the engine is hot to prevent
dangerous coolant leaks.
