5.4 Protection against short-circuit and overload
The generator is protected against short-circuit and
overload. A tripolar magnetothermal switch [Fig. 4 Ref.
2] cuts the supply of electric current when a short-circuit
occurs or when the electric current delivered exceeds
the nominal value.
Before restoring the contact by lifting the lever of the
magnetothermal switch, disconnect the utilities.
5.5 Protection against short-circuit of the
low-voltage electric system
In the event of a short-circuit in the low-voltage electric
system, a thermal switch [Fig. 4, Ref. 3] breaks the
circuit stopping the generator. In this case the warning
lights of the engine protection module will all be off and it
will not be possible to re-attempt starting.
Before restoring the electric circuit by pressing the button
located on the thermal switch [Fig. 4 Ref. 3], have a
specialised technician find and remove the cause of the
short-circuit.
6 MAINTENANCE
Any maintenance operation on the generator must
be carried out with the engine off after letting it cool
down sufficiently, and must be carried out by
authorised personnel.
Before accessing the generator, disconnect one pole
of the starter battery in order to prevent accidental
starting.
6.1 Ordinary engine maintenance
The periodic maintenance to be carried out on the engine
is listed in TABLE “B”.
For more detailed information consult the manual provided
with each generator by the engine manufacturer.
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].
6.2 Engine oil and oil filter change
The engine oil sump capacity is 3.6 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. ?],
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.
6.3 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
