MAINTENANCE
-) Put on safety gloves and insert bearing into its place
b) Cleaning of air filters (if available)
Air filters are optional parts that are supplied upon request; these
devices must be cleaned on a regular basis; inside these filters
there is a mesh net that has to be kept clean in order to ensure a
good performance of the filter. The time interval between each
cleaning operation depends on the conditions of the installation
site. A frequent inspection of these parts will establish if any clea-
ning is required. Make sure you turn off the generator set when
performing cleaning operations of such parts as their removal en-
tails contact with live parts.
c) Cleaning of windings
Both windings and generator will last longer with a correct mainte-
nance and cleaning; an inspection and a maintenance schedule
should be established by keeping in mind that the frequency of
these inspections depends on the conditions of the site where the
generator is being used.
If the generator is used in a dry and clean environment, an inspec-
tion a year is enough; in case of severe conditions, inspections
must be carried out more frequently.
However, we recommend that a check should be done, regardless
of the schedules, in the following cases:
-) in case of rust
-) in case of corrosion
-) when the insulation is damaged
-) when there is dust on the surface of the windings
To clean windings, use solvents like oil of turpentine or "Solvesso"
solvent. Cleaning with such substances, which contain a high eva-
poration level, will not damage the isolation level of the windings.
When cleaning is over, please look out for any overheating or car-
bonisation signs.
We also recommend drying up of windings at 60-80°C and if you
notice that the varnish of windings is not in good shape, then have
them varnished again.
