4 - SERVICING - MAINTENANCE

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 state.
All such operations performed on the
alternator should be undertaken by
personnel 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 intervention 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 - Checks after start-up
After approximately 20 hours of operation,
check that all fixing screws on the machine
are still tight, plus the general state of the
machine and the
connections in the installation.
4.2.2 - Bearings
The bearings are permanently greased and
they have a life of (20,000 hrs) or 3 years.

Replacement 20 000 hrs or 3 yrs 20 000 hrs or 3 yrs
The bearings are regreasable (option). It is
advisable to lubricate the alternator during
operation and when it is first commissioned.
The lubrication characteristics are given in
the table below.

Quantity of grease
Lubrication interval
Lubrication intervals are given for grease
type: LITHIUM - standard - NLGI 3.
In the factory, the grease used for lubrication
is: ESSO - Unirex N3.
Before using another grease, check for
compatibility with the original one. Monitor
the temperature rise in the bearings (see
section 4.4).

4.2.3 - Electrical servicing
Commercially-available volatile degreasing
agents can be used.
Do not use: trichlorethylene, perchlo-
rethylene, trichloroethane or any alkaline
products.
These operations must be performed at a
cleaning
vacuum system that collects and flushes
out the products used.
The insulating
impregnation system are not at risk of
damage from solvents. Avoid letting the
cleaning product run into the slots.
Apply the product with a brush, sponging
frequently to avoid accumulation in the
housing. Dry the winding with a dry cloth. Let
any traces evaporate before reassembling
the machine.
4.2.4 - Mechanical servicing
Cleaning the machine using water or a
highpressure washer is strictly prohi-
bited. Any problems arising from such
treatment are not covered by our
warranty.
Degreasing: Use a brush and detergent
(suitable for paintwork).
Dusting: Use an air gun.
If the machine is fitted with air inlet and outlet
filters, the maintenance personnel should
clean them routinely at regular intervals. In
the case of dry dust, the filter can be cleaned
using compressed air and/or replaced if it is
3
clogged.
After cleaning the alternator, it is essential to
check the winding insulation (see sections
3.2 and 4.8).

4.3 - Fault detection

If, when commissioned, the alternator does
not work normally, the source of the
malfunction must be identified (see sections
4.4 and 4.5).
