GENERATORS
- Magnetothermic circuit breakers to the low voltage
outlets; these break the circuit whenever the voltage at a
given outlet is higher than the nominal voltage for that
particular outlet.

6 MAINTENANCE

PRECAUTION
All maintenance operations on the generator must be
performed by authorized personnel. Maintenance
must be performed after the engine has been turned
off and has cooled down sufficiently.

6.1 Ordinary engine maintenance

The periodic maintenance required for the engine is
reported in the table. For more detailed information, see
the manual supplied by the engine manufacturer and
attached supplied with the generator.
ATTENTION
Check the oil level using the special, graduated dip
stick (fig. 2 ref. 3).
The oil level must always be between the MAX and
MIN level notches on the stick.

6.2 Changing the engine oil

Use AKROS TURBO 15 W 40 oil
The oil tank is filled and topped up through the hole
indicated in fig. 3 ref. 4.
For more detailed information, see the engine use and
maintenance manual provided with the machine.
To change the engine oil, first remove the lower hatch
closing the soundproofing case. Then withdraw the cap
located on the oil sump and drain it into a container placed
under the body.
It is advisable to drain the oil when it is still sufficiently
warm as it will flow more easily.
ATTENTION
Do not disperse spent oil in the environment as it
causes pollution.
Deliver spent lubricating oil to special Collection
Centres which handle disposal.
6.3 Venting the system
The presence of air bubbles in the fuel system can cause
the engine to run irregularly or prevent it from reaching its
nominal r.p.m. Air can penetrate the fuel circuit through
imperfectly sealed joints (i.e. piping, filters, tanks) or
when the level of fuel in the tank is at a minimum. To
eliminate air bubbles from the fuel circuit one must first
eliminate the failure which allowed the air to enter in the
UK
first place. The following operations must then be per-
formed:
1 - Turn the ignition key clockwise one click so that the
shut-off solenoid valve is opened.
2 - Loosen the vent screws located on the fuel filter and
on the injection pump (see the engine use and
maintenance manual).
3 - Manually manipulate the AC fuel pump lever until the
all the air in the system has been eliminated through
the vent screws (fig. 3 ref. 5).
4 - Tighten the vent screws once more and start up the
engine.
5 - Repeat the above operations if the engine is still not
functioning properly.
INFORMATIONS
Consult the engine use and maintenance manual for
further details on the fuel system.

6.4 Replacing the air filter

To ensure proper functioning and long engine life it is
important to clean and periodically replace the air filter
cartridge. An inefficient filter can cause loss of engine
power and can give rise to excessively smoky exhaust.
To replace the air filter cartridge operate as follows:
- Remove the plastic lid from the air filter after having
removed the securing screws;
- Remove the filter cartridge and insert a new one
positioning it carefully;
- Replace the lid and tighten it with the securing screws.
ATTENTION
Clean the air filter cartridge every 200 hours of opera-
tion.
Shorten this interval if the generator is operated in a
particularly dusty environment.
Replace the cartridge when it is excessively fouled or
damaged.
6.5 Cleaning the air intake grids
Periodically check the cooling air intake and discharge
grids (fig. 2 ref. 4-5) and the cylinder cooling fins for fouling.
These must be free of any foreign bodies which could
obstruct the flow of cooling air (i.e. leaves, paper, rags,
etc.).
6.6 Periods of inactivity
If the unit will not be used for a long period of time, the
following operations must be performed:
- replace the engine oil sump;
- replace the fuel filter;
- remove the injector, insert a few drops of oil inside the
combustion chamber and manually rotate the drive
shaft a few times; reinstall the injector and close the
suction and delivery openings.
