1 GENERAL INFORMATIONS
1.1 CONFORM USE
The generator is suitable for independent production of electrical energy within the voltage and wattage limits
declared by the manufacturer.
Any other use outside the already stated field of use is prohibited: the generator is intended for marine use.
The generator has been designed to operate independently (without operator) if not for sporadic checks.
The limits of use are:
-operating temperature: -10° +40°
-relative humidity: 30% - 90%
-the generator is suitable for marine operation.
Installations are subject to approval by maseor by an installer authorised by mase.
Arbitrary modifications to the machine are prohibited for safety reasons.
Original spare parts must be used on pain of losing machine conformity.
All the operations that require dismantling of special parts may only be carried out by technicians authorised by
the local dealer or the manufacturer.
Only masetechnicians or personnel trained by masehave the necessary knowledge of the generator and
the special equipment as well as the experience to carry out any operation in the most economical and reliable
way.
1.2 RESIDUAL RISKS
The generator has been designed taking into account the safety regulations set out in the EC directives and
standards; nonetheless, the following residual risks remain:
-injury caused by contact with hot parts during maintenance.
-injury caused by electrocution during maintenance on the electric panel.
-risks connected with long periods of exposure to the noise of the generator (with open cowling).
-risks due to contact with the generator lubricants during maintenance.
-risks due to the fire hazard the fuel represents.
Because of the typical intrinsic danger of the Generators, you are reminded that, although the generator has
been designed, constructed and tested in accordance with the safety regulations, only proper and careful use
can guarantee full safety; to this end, the various precautions to be taken during use of the Generator are
listed below.

BATTERY
Do not touch the electrolitic battery acid
Sufficient ventilation of the battery area.
• Keep the area around the battery well ventilated, paying attention to keep
sparks, open flame and any other form of ignition away. During engine running or
charging battery, hydrogen gas is produced from the battery and
can be easily ignited.
Battery acid. Sulfuric acid in batteries can cause severe injury or death.
Sulfuricacid in batteryccancausepermanentdamagetoeyes,burn,skin,andhole
in clothing.
Always wear splash-proof safety googles when working near the battery. If battery
acid is splashed in the eyes or skin, wash immediately the affected area with large
quantity of clean water. Seek immediate medical aid in case of eyes contact.
Do not intentionally make the battery spark by short-circuiting to check its
remaining charge. It will cause fires.
Make sure to use a gravimeter to check the remaining charge of the battery.
If the battery electrolyte frozen, recharge the battery after warming up to
thaw it.
SAFETY CLOTHING
Do not expose your skin to high pressure fuel spray
Be careful so as not to bring your skin in contact with high pressure fuel spray
from broken fuel injection pipe to penetrate your skin to cause inflamed.
If exposing to the spray should occur, obtain prompt medical treatment.
Beware of dirt from air blowing
Wear protective equipment such as goggles to protect your eyes when
blowing compressed air or steam. Dust or flying debris can hurt eyes.

(1) Limited - time running power (LTP) ISO 8528-1
It is the maximum power that, under the environment conditions established by the norm ISO 3046/1, the generator group it is able to disburse for
a maximum of 500 hours for year, of which a maximum of 300 hours among the interval of maintenance prescribed by the builder. It is accepted
the operation to this power conditions the duration of the group.
An overload of the 10% is admitted only for regulation.
(2) Prime power (PRP) ISO 8528-1
It is the available maximum power for a variable power cycle that the generator group is able to disburse for a boundless number of hours for year
among the interval of maintenance prescribed by the builder and under the environment conditions established by the norm ISO 3046/1. The middle
power during a period of 24 hours, doesn't have to exceed 80% of the PRP.

3 INSTALLATION
The generator may only be installed by qualified
technicians. Malfunctioning due to improper
installation may cause injury or death.
3.1 GENERATOR HOUSING CHARACTERISTICS
-Thegeneratormustbeinstalledinasufficientlyventilated
room able to assure the small amount of air required for
enginecombustion.
- The room must be acoustically separated and isolated
fromthe livingquarters.
- The generator must be positioned in such a way as to
facilitatenormal maintenanceoperations.
- It is advisable to install the generator in the
propulsionengine room provided that itmeets the
aboveconditions.
- The air must be clean.
-The air temperaturein the placeof installation must be
between-5°C(23°F) and +40°C(104°F).
- The relative humidity must not exceed 50% at a
maximumtemperatureof+40°C.Relativehumidityof90%
at+20°C(68°F)and100%at+25°C(77°F)ispermissible.

3.2 LIFTING
Followthe procedure onChap.7 to liftthe generator.
Thefixinghole forthehook isindicatedon picture (ref.1).
3.3 ANCHORING THE GENERATOR
To anchor the generator, arrange a base to support the
weightandvibrations.
Drill holes in the base as shown on layout drawing.
3.4 VENTILATION
Thegeneratoris equippedwithan internalforcedcooling
systemthrough a water/air exchanger.
Theamount of air required forcombustion is
aspiratedthrough the intake located onthe base (ref.2):
Therefore, always check that this intake is
freeof any obstruction.
3.5 COOLING WATER CIRCUIT
Thegeneratorengineis cooled bywaterinsideaclosed
circuit, through a cooler (ref.3) and sea water.
Use 4 L of water mixed with coolant at 50 %.
At the time of installation, a seawater feed circuit
mustbe arrangedfor cooling,and an exhaust system for
the combustion gas and water mixture.
3.5.1 SEAWATER FEED SYSTEM
Twowater intakesystemsare normally adopted onboats:
-Direct intake system (ref.4).
-Systemwith baffle (ref.5).
maserecommends using the direct intake system
(ref.3),since it prevents intake ofpressurised water into
the intake ducts, instead generating a vacuum easily
overcomeby thewater pumphead ofthe generator.
Do not fit any type of protection cap on the direct
intakesystem.
The system with baffle (ref.5), on the other hand, may
causethe following problems:
a- If mounted with the slots facing the bow:
Inthis case, duringnavigation andwith the generatoroff,
pressure is created in the water intake duct, which may
cause the system to fill up until reaching the exhaust
port, thus making it possible for water to enter the
cylinders.
b- If mounted with the slots facing the stern:
Inthis case,during navigationa vacuum may be created
inthe waterintake duct such as toinhibit thewater pump
toactivate the coolingsystem or such as tolimit the flow
ratewith consequent overheatingof thegenerator.

3.5.2 COMPONENTS
If the generator is installed at a height over 1m (3,3ft)
above the waterline, a check valve (ref.2) must be
fitted after the seawater intake to prevent the water
circuit from emptying out when the engine is off. If
the circuit is empty, the water pump impeller may be
damaged during starting.
For the same reason, when starting the generator for
the first time, manually prime the intake pipe leading
from the valve to the pump.
-1/2" direct seawater intake (ref.1).
-1/2" ball cock (main system) (ref.3).
-1/2" ball cock (system bleeding) (ref.4).
Servesto drain the cooling systemof thegenerator for
generalmaintenance orfor longperiods of inactivity.
-Waterfilter (inspectable) (ref.5).
Itprotects effectively thecooling circuit againstintake
ofmud, sand andseaweed.
The filter mesh must be the fine type, it is advisable

m(micron)pitch. Different
sizes would not allow good filter efficiency.
- Antisiphon valve (ref.6): this valve brings the cooling
circuit to atmospheric pressure when the engine is off,
preventingthesiphonagephenomenon.
It must be used when the base of the generator is
under the water line, and must be positioned at least
500mm(1.6ft) above sealevel.
The drain pipe of the antisiphon valve must be
positionedunder thevalvethus preventingwaterfrom
accumulating in the pipe which must always remain
empty to allow air to pass through it when the
generator is switched off.
It is advisable to run the drain pipe through the bilge,
as small amounts of water may flow from it during
normal operation.
Holes have been made in the casing to connect the
antisiphon valve (ref.7).
