Preparation for running after storage
Before using again the generator, remove the plastic
bag, the VCI paper and the silica-gel bags, and
carefully inspect the generator (follow the check
list "Before startup").
– Refer to the engine running manual.
– The insulation resistance of the coils should be
evaluated by electrical technician if the value
reaches values below 100 M
Ω
.
– Replace the fuel filter and refill the fuel container.
Vent the fuel system.
– Install the battery again, recharge it, and if
necessary connect it.
– Conduct a generator running test.
Inspections and troubleshooting
Never conduct a running test with the
electric cables connected. Never touch
an electric terminal without checking
the voltage.
In case of failure, always make a
report of the situation, before, during
and after the damage. In order to
o b t a i n a q u i c k f a u l t l o c a t i o n ,
information about the load can be
useful (type, dimension, power factor,
etc.), vibration, exhaust gas color,
insulation check, smells, output
voltage, leakages and damaged parts,
ambient temperature, daily and
normal maintenance and altitude.
Also mention all data about humidity
and generator location (e.g. close to
the sea).
Generator storage
Storage
– Store the generator in a dry compartment, with
temperature above the freezing point and well
ventilated.
– Run the engine regularly, for example once a
week, until it warms up.If it is not possible to
observe this procedure, take the following
additional precaution measures:
• Refer to the engine operation manual.
• Remove the battery. Store it in a dry room,
with temperature above the freezing point.
Keep the battery clean and slightly cover
the terminals with lubricating mass.
Regularly recharge the battery.
• Clean the generator and keep all the electrical
components protected for moisture.
• Place silica-gel bags, volatile corrosion inhibitor
(VCI) paper or any other drying agent inside
the generator and close the covers.
• With the use of adhesive tape, fasten VCI paper
sheets to the frame in order to cover all the
openings.
• Wrap the generator, except for the bottom,
with a plastic bag.
