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
ils original state
&
Ali 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 persona! 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.
Warning : During and after running, the
alternator will reach temperatures hot
enough to cause injury, such as burns.
4.2 - Routine maintenance
• Checks after start-up
After approximately 20 hours of operation,
check that all fixing bolts on the machine are
still tight, plus the general state of the
machine and the various electrical
connections in the installation.
• Electrical servicing
Commercially-available volatile degreasing
agents can be used.
[WARNING)
Do not use: trichlorethylene, perchlo
rethylene, trichloroethane or any alkaline
products.
These operations must be performed at a
cleaning station, equipped witha vacuum
system that collects and flushes out the
products used.
The insulating components and the
impregnation system are not at risk of
damage from solvants. 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.
• Mechanical servicing
(WARNING)
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 in let and outlet
filters, the maintenance personnel should
clean them routinely at regular intervals. ln
the case of dry dust, the filter can be cleaned
using compressed air and/or replaced if it is
clogged.
After cleaning the alternator, it is essential to
check the winding insulation (see sections
3.2 and 4.5).
