MAINTENANCE
CAUTION:
Never work on the machine, whether with hands or tools, while
it is operating. Before any maintenance work make sure that
the machine is at a standstill and disconnected from the tractor,
or that the tractor is turned off and the ignition key has been
removed, and the switches have been turned OFF.
1.
If any malfunctions should arise in the machine, check that they
do not depend on a lack of routine maintenance.
2.
Mechanical controls:
2.1 Check on a monthly basis or whenever starting up that
there are no unusual noises or vibrations. Check that the
alternator's air ducts are not clogged.
2.2 Periodically check the oil level in the overgear. Change oil
every 500 working hours and at least every year.
3.
Electrical controls:
3.1 Check on a monthly basis or whenever starting up that the
circuit breaker works: while the machine is running (at
rated voltage) press the test button and the breaker must
trip. Check the effi ciency of the earth connection.
3.2 Every 500 working hours and at least every year, check the
wear of the brushes and manifold and the correct operation
of the switchboard's measurement instruments, checking
their readings with a standard instrument.
4.
Never wash the machine with direct or high pressure jets of
water or with aggressive agents.
5.
Never rest liquid containers or infl ammable materials on the
machine
6.
Keep the machine away from heat sources or humidity and never
install it in explosive atmospheres.
7.
In case of fi re use a powder fi re extinguisher.
NOTES ON THE OPERATION OF THE SWITCHES
The overload cutout may trip for two reasons:
-
when the appliance or group of appliances connected require a
greater current than the breaker can support.
-
because of a short circuit.
In the fi rst case it is suffi cient to reduce the load and restart the
generator, while in the second case fi nd the cause behind the short
circuit and eliminate it.
The circuit breaker trips because of a defect in the circuit
insulation downline to the generator. This safety (if combined
with an effi cient earth plant) guarantees the best protection
against hazards of indirect contact.
SCRAPPING THE MACHINE
If the machine has to be scrapped, proceed as follows:
-
drain the oil from the overgear and dispose of it as for old oil
-
separate the plastic parts from the metal parts and have them
collected by authorised disposal companies.
!
To check or top up the oil level, proceed as follows:
1.
unscrew the caps from the holes A and B as in fi g.3
2.
add oil through the top hole A until oil begins to leak out of the
hole B.
3.
replace the caps.
For multipliers different from the previous one, check the oil level
through the sight glass. (fi g.4-5)
fi g. 4
To check the wear of the brushes and of the manifold, proceed as
follows:
1.
slacken the screws and remove the rear grille
2.
measure the length of the brushes:
2.1 (fi g.6) in series GT and GS generators there must be at least
10mm of carbon outside the brush-holders,
2.2 (fi g.7) in series ET and FT generators, slacken the screw,
remove the brush-holder and check that the brushes pro-
trude by at least 4mm
3.
check that the manifold looks and feels smooth
4.
replace the grille.
