5 CARE AND MAINTENANCE
5.1 Preamble
Any maintenance operation on the generator must be carried out with the engine off and leaving it to cool
down sufficiently, and must only be carried out by authorised and suitably trained personnel.
It is important to regularly inspect and carry out maintenance on the generator; the frequency of maintenance should
be decided on the basis of the number of hours of operation, as shown in the table at point
5.7
.
5.2 Ordinary engine maintenance
It is recommended to scrupulously follow the instructions in the manual provided by the engine manufacturer with
each generator.
The periodical maintenance operations to be carried out on the engine are indicated in the table at point
5.7
.
• Daily check the oil level with the graduated dipstick (Fig.4, Ref. 3); the oil level must always be between
the MAX and MIN notches on the dipstick (see Fig. 6).
• When checking the engine oil level, ensure that the generator is positioned horizontally.
5.3 Engine oil change
The engine is supplied with oil for petrol-powered engines with viscosity
SAE 10W/30
.
Always check correct viscosity of the engine oil in relation to the range of ambient temperatures in which the
generator operates as indicated in the table in Fig. 5.
Top-up and fill through the hole indicated in Fig.
4
Ref.
3
.
To change the engine oil, first remove the cap on the lower part of the oil sump (Fig.
4
, Ref.
2
) and drain the oil into
a collection container.
It is recommended to drain the oil when it is still sufficiently warm to flow easily.
Close the drain plug and fill the sump with the quantity of oil necessary to bring it up to the maximum level.
Oil sump capacity
1.1 l
.
• Dispose of the used oil in an appropriate manner, since it is a polluting product.
• Take the used engine oil to special Collection Centres for disposal.
• Carry out the first oil change after the first 20 hours of operation, and subsequently every 50 hours.
5.4 Spark plug maintenance
Spark plug type:
NGK - BR6HS
DENSO - W20EPR-U
The carbonaceous residues which with use deposit on the spark plug must periodically be removed (Fig.
2
, Ref.
4
)
using a small metal brush or specific detergent.
Adjust the distance of the spark plug electrodes resetting a value of
0.7 - 0.8 mm
(Fig.
6
).
