Before approaching the genera-
tor disconnect one of the poles of the start battery so
that it cannot be accidentally started up.

5.1 Routine maintenance of the engine

The regular tasks that must be carried out on the engine
are shown on the table.
For more detailed information, consult the manual sup-
plied by the engine manufacturer that accompanies
each generator .
Use the dipstick to check the oil
level [fig. 4, ref. 1]. The level must always be between
the MAX. and MIN notches on the dipstick [fig. 4, ref.
2] .

5.2 Changing engine oil and oil filter

The engine sump has the following capacity:
IS 11 - 13.5 L. 4.7
IS 15 - 18.5 L. 5.8
IS 21 - 23 L. 10.2
Oil must be poured in and topped up through the hole [fig.
7, ref. 1 - 2].
To change the oil the engine sump, remove the dipstick
[fig. 4, ref. 2], remove the screw that serves as a cap and
use the extraction pump [fig. 7, ref. 3].
Drain the oil whilst it is still warm enough to allow it to
drain off easily.
See Table "A", fig. 4 for information on recommended
oils.
The engine oil must be changed
for the first time after 50 hours of generator opera-
tion; the second and subsequent oil changes can
take place every 200 hours.
For more detailed information on
engine lubrication consult the engine use and main-
tenance manual that accompanies the generator.
Do not dump used oil as it is a
polluting product.
Deliver the lubricating oil to the collection centres
that are responsible for the disposal of oil.
Do not allow the engine oil to
come into contact with the skin. During mainte-
nance operations use protective gauntlets and gog-
gles.
If the lubricating oil comes into contact with the eyes
or skin, wash the affected part immediately and
GB
thoroughly with soap and water.
To replace the engine oil filter [fig. 7, ref. 4], unscrew it
from its support using the tools that are normally com-
mercially available. Refit the new filter and take care to
lubricate the ring seal. The first filter must be changed
after 50 hours of generator operation and the second
and subsequent ones must be changed every 400
hours.
For further information, see the engine use and mainte-
nance manual.
use only manufacturer approved spare parts.
When operations have been com-
pleted, thoroughly clean all the parts of the genera-
tor that are covered in oil and fuel.

5.3 Cleaning the air filter

The IS series generators have a dry air filter that stops
foreign bodies from entering the combustion chamber.
Clean the filter with paraffin once a year to free it of
impurities.
Do not dump the liquids used for
washing the air filter but take them to an approved
collection centre.

5.4 Replacing the fuel filter

In order to ensure that the engine has a long working life,
the fuel filter must be replaced regularly at the intervals
indicated by the engine manufacturer on the table set
out in paragraph 5.12.
To change the fuel filter, follow this procedure:
- close the fuel valve [fig. 6, ref. 3].
- loosen the supporting ringnut completely [fig. 6, ref. 4]
- remove the old cartridge and fit the new one
- to fit again repeat the operations in the reverse order.
After the filter has been replaced, the supply system
must be bled to remove all the air bubbles that have
formed inside (see paragraph 3.2).
Do not allow the fuel to come into
contact with the skin. During maintenance opera-
tions use protective gauntlets and goggles.
If the lubricating oil comes into contact with the eyes
or skin, wash the affected part immediately with
soap and water.
After the fuel has been drained,
carefully clean off all traces of fuel and take the rags
to the appropriate collection centre.
