•
Unscrew the engine oil level reference cap
and clean the dipstick (Fig. 23 ref. 1).
•
Put the dipstick back in without screwing.
•
Take the dipstick out again, and make sure
that the engine oil level is between the two
notches (min and max). Should the oil level be
below the minimum notch, restore the level of
the oil with the kind of motor oil advised (refer
to the engine user and maintenance manual).
•
Put the dipstick cap back on and screw tightly.
Do not exceed the
maximum level, since this could cause
malfunction of the fuel pump and hence of
the generating set.
Every engine oil level
checking operation must be performed with
the generating set in a perfectly horizontal
position.
7.4 Maintenance operations calling for
qualified personnel
With certain maintenance operations, it is
possible to lower the engine-alternator unit,
removing the hexagonal-headed screws (Fig. 24
ref. 1) and loosening the two studs (Fig. 24 ref.
2).
This will make it easier to access all the inside
parts of the generating set for unscheduled
maintenance or repair operations.
7.4.1 Engine oil replacement
Use multigrade detergent oil for four-stroke petrol
engines having a SAE viscosity suited to the
climate the generating set is working in (see table
and detailed instructions shown on the engine
use and maintenance manual).

For cold climates
To make it easier to take the engine oil out, it is
best to heat the engine for 3 - 5 minutes; this
way, the oil will be more fluid and emptying will
be quicker and more complete.
Loosen the special cap on the oil pan by a few
turns, and let all the oil inside run out into a
collection container (Fig. 25 ref. 1).

When this has been done, screw the cap back on
again and restore the oil level inside the engine
pan, using the filler hole (Fig. 23 ref. 2).
For the quantity of oil to be fed into the pan, see
the following table (Table 2).
