This use and maintenance manual is an important
part of the machines in question.
The assistance and maintenance personel must
keep said manual at disposal, as well as that for
the engine and alternator (if the machine is
synchronous) and all other documentation about the
machine.
We advise you to pay attention to the pages
concerning the security (see page M1.1).

INFORMATION
Dear Customer,
We wish to thank you for having bought from
MOSA a high quality set.
Our sections for Technical Service and Spare
Parts will work at best to help you if it were
necessary.
To this purpose we advise you, for all control and
overhaul operations, to turn to the nearest
authorized Service Centre, where you will obtain
a prompt and specialized intervention.
☞In case you do not profit on these Services and
some parts are replaced, please ask and be
sure that are used exclusively original MOSA
parts; this to guarantee that the performances
and the initial safety prescribed by the norms in
force are re-established.
☞The use of non original spare parts will cancel
immediately any guarantee and Technical Ser-
vice obligation from MOSA.
NOTES ABOUT THE MANUAL

10/10/02 M1-4 GB
Any of our product is labelled with CE marking attesting its conformity to appliable directives
and also the fulfillment of safety requirements of the product itself; the list of these directives is
part of the declaration of conformity included in any machine standard equipment.
Here below the adopted symbol:
CE marking is clearly readable and unerasable and it can be either part of the data-plate (A) or
placed as a sticker near the data-plate (B)
AB
Furthermore, on each model it is shown the noise level value; the symbol used is the following:
The indication is shown in a clear, readable and indeleble way on a sticker.

The generating set GE 22 is a unit which transforms the mechanical energy, generated by endothermic engine, into electric
energy, through an alternator.
Is meant for industrial and professional use, powered by an endothermic engine; it is composed of various main parts such as:
engine, alternator, electric and electronic controls, the fairing or a protective structure.
The assembling is made on a steel structure, on which are provided elastic support which must damp the vibrations and also
eliminate sounds which would produce noise.

OUTPUT
Declared power according to ISO 8528-1 (temperature 25°C, 30% relative humidity, altitude 100 m above sea level).
(*Stand-by) = maximum available power for use at variable loads for a yearly number of hours limited at 500 h. No overload is
admitted.
(**Prime power P.R.P.) = maximum available power for use at variable loads for a yearly illimited number of hours. The average
power to be taken during a period of 24 h must not be over 80% of the P.R.P.
It’s admitted overload of 10% each hour every 12 h.
In an approximative way one reduces: of 1% every 100 m altitude and of 2.5% for every 5°C above 25°C.
ACOUSTIC POWER LEVEL
ATTENTION: The concrete risk due to the machine depends on the conditions in which it is used. Therefore, it is up to the end-
user and under his direct responsibility to make a correct evaluation of the same risk and to adopt specific precautions (for
instance, adopting a I.P.D. -Individual Protection Device)
Acoustic Noise Level (LWA)- Measure Unit dB(A): it stands for acoustic noise released in a certain delay of time. This is not
submitted to the distance of measurement.
Acoustic Pressure (Lp) - Measure Unit dB(A): it measures the pressure originated by sound waves emission. Its value
changes in proportion to the distance of measurement.
The here below table shows examples of acoustic pressure (Lp) at different distances from a machine with Acoustic Noise
Level (LWA)of 95 dB(A)
Lp a 1 meter = 95 dB(A) - 8 dB(A) = 87 dB(A) Lp a 7 meters = 95 dB(A) - 25 dB(A) = 70 dB(A)
Lp a 4 meters = 95 dB(A) - 20 dB(A) = 75 dB(A) Lp a 10 meters = 95 dB(A) - 28 dB(A) = 67 dB(A)
PLEASE NOTE: the symbol when with acoustic noise values, indicates that the device respects noise emission limits
according to 2000/14/CE directive.

BATTERY WITHOUT MAINTENANCE
Connect the cable + (positive)
to the pole + (positive) of the
battery (after having taken
away the protection), by
properly tightening the clamp.
Check the state of the battery
from the colour of the warning light which is in the
upper part.
- Green colour: battery OK
- Black colour: battery to be recharged
- White colour: battery to be replaced
DO NOT OPEN THE BATTERY.
RECOMMENDED OIL
MOSA recommends selecting AGIP engine oil.
Refer to the label on the motor for the recommended
products.
LUBRICANT
Please refer to the motor operating manual for the
recommended viscosity.
It is dangerous to fill the motor with too much oil,
as its combustion can provoke a sudden increase
in rotation speed.
ATTENTION
FUEL
Do not smoke or use open flames during
refuelling operations, in order to avoid
explosions or fire hazards.
Fuel fumes are highly toxic; carry out
operations outdoors only, or in a well-
ventilated environment.
Avoid accidentally spilling fuel. Clean
any eventual leaks before starting up
motor.
ATTENTION
Refill the tank with good quality diesel fuel, such as
automobile type diesel fuel, for example.
For further details on the type of diesel fuel to use,
see the motor operating manual supplied.
Do not fill the tank completely; leave a space of
approx. 10 mm between the fuel level and the wall
of the tank to allow for expansion.
In rigid environmental temperature conditions, use
special winterized diesel fuels or specific additives
in order to avoid the formation of paraffin.
GROUNDING CONNECTION
The grounding connection to an earthed installation
is obligatory for all models equipped with a
differential switch (circuit breaker). In these groups
the generator star point is generally connected to
the machine’s earthing; by employing the TN or TT
distribution system, the differential switch
guarantees protection against indirect contacts.
In the case of powering complex installations
requiring or employing additional electrical protection
devices, the coordination between the protection
devices must be verified.
For the grounding connection, use the terminal
(12); comply to local and/or current regulations in
force for electrical installations and safety.
REFUELLING AND CONTROL:
Carry out refuelling and controls with motor at level
position.
1. Remove the oil-fill tap (24)
2. Pour oil and replace the tap
3. Check the oil level using the dipstick (23); the oil
level must be comprised between the minimum
and maximum indicators.
DRY AIR FILTER
Check that the dry air filter is correctly installed and
that there are no leaks around the filter which could
lead to infiltrations of non-filtered air to the inside of
the motor.
OIL BATH AIR FILTER
Fill the air filter using the same engine oil up to the
level indicated on the filter.
