4.1 - Safety measures
Servicing or troubleshooting must be
carried out strictly in accordance with
instructions so as to avoid the risk of
accidents and to maintain the machine in
its original condition.
All such operations performed on the
alternator should be undertaken by staff
trained in the commissioning, servicing
and maintenance of electrical and
mechanical components, who must
wear personal protective equipment
appropriate for mechanical and electrical
hazards.
Before any work is carried out on the
machine, ensure that it cannot be started by
a manual or automatic system and that you
have understood the operating principles of
the system.
4.2 - Routine maintenance
4.2.1 - Inspection after start-up
After approximately 20 hours of operation,
check that all fixing screws on the machine
are still tight, plus the condition of the
gearbox (traces of oil) and the various
electrical connections in the installation.
4.2.2 - Ventilation circuit
Ensure that the suction grilles are not
blocked by foreign bodies (straw, feathers,
wool, etc.).
4.2.3 - Bearings
The bearings are permanently greased (see
the alternator manual). A quick check of all
the generator bearings can be carried out by
turning the shaft end by hand; the assembly
should turn freely without sticking.
4.2.4 - Gearbox
The gearbox oil should be emptied and
replaced after 50 hours of operation, then
every 500 hours and in all cases, at least
once a year.
Quality of oil to be used: SAE 90 oil
Quantity of oil for GT3, TF3,TM3 16.5 - 20 =
0.75 kg / 0.6735 litre
Quantity of oil for GT3, TF3, TM3 27.5 - 66 =
1.5 kg / 1.347 litre
Check the filling level with the aid of the
gearbox oil level gauge, part number (552).
4.2.5 - Servicing and storage
Cleaning the machine using a water
spray or a high-pressure washer is
strictly prohibited.
Any problems arising from such
treatment will not be covered by our
warranty.
Store your machine in a dry, airtight place to
avoid condensation.
4.3 - Fault detection
If, when commissioned, the alternator does
not work normally, the source of the
malfunction should be identified.
To do this, check that :
-the protection devices are switched on,
- the connections comply with the diagrams
in the maintenance manuals supplied with
the machine,
- the generator speed is correct, see section
2.3 (use a frequency meter rather than a
revolution counter).
Repeat the operations defined in
section 3.
