GENERATORS
ATTENTION
When the generator is connected to the automatic
control panel the ignition key located in the instru-
ment panel must remain in the OFF position.
For all versions (where the key
DANGER
must remain in the ON position), set the LOCK
function when carrying out maintenance or repair
operations on the generator, to prevent it from
starting in the event of a power failure.

5 PROTECTIONS

The units are equipped with a series of protections to
safeguard them from improper use and from failures which
could compromise their function. These protect against:
- Low oil pressure
This cuts in, turning off the unit, whenever there is
inadequate pressure in the lubrication circuit; when it cuts
in a LED (fig.6 ref. 15) goes on.
In this case, adding additional oil is usually enough to
start up the unit once more.
ATTENTION
The low oil pressure protection does not provide any
indication as to the oil level. To prevent damaging the
engine, it is essential to check the oil level periodi-
cally.
- High engine temperature
This protection cuts in, turning off the unit whenever the
engine operating temperature is too high. When activated
a LED (fig.6 ref. 18) goes on.
In this case, the unit can only be started up again after the
cause has been identified and eliminated.
- Short circuits and overloads
To protect against short circuits and overloads, the unit is
equipped with magnetothermal and differential breakers
which cut off the power supply when the alternator is
overloaded or there is a short circuit.
Before powering the unit again by flipping the
magnetothermal breaker levers (fig.6 ref. 8-9) back to the
ON position, the problem which caused it to trip must be
removed.
For this purpose the following breakers are used:
- the general differential magnetothermal circuit breaker:
in the case of short circuit, overload and current leakage
to ground, this cuts off the power supply to all outlets
(fig.6 ref. 8).
- Magnetothermal 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. 9 and fig. 4 ref. 1).
The oil level must always be between the MAX and
MIN level notches on the stick.
6.2 Changing the engine oil and filter
Use AKROS TURBO 15 W 40 oil
The oil tank is filled and topped up through the hole
indicated in fig. 2 ref. 10 and fig.4 ref. 3.
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. Provide to replace the oil
filter (fig.2 rif 13) every 200 hours as from chart Par. 6.7
ATTENTION
Do not disperse spent oil in the environment as it
causes pollution.
Deliver spent lubricating oil to special Collection
Centers 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
first place. The following operations must then be per-
formed:
1 - Loosen the vent screws located on the fuel filter and on
the injection pump (see the engine use and mainte-
nance manual).
