warning:
the use of oil that does not conform to the technical specifications on chapter 9 will cause serious damage to
the engine and invalidate the guarantee.

when supplying the engine never ingest oil, fuel, coolant liquid, etc.. these substances are harmful to the
personal health of the user if ingested

4.2.2 FILLING THE COOLING CIRCUIT

As a refrigerating liquid, an anti-freeze of the brand KRAFFT ACU
2300 CC 50% Ref. 1325 or another one with similar specifications

must be used.

The incorrect use of water in the refrigeration circuit is extremely
harmful, causing corrosion and scaling, while the use of anti-freeze
protects the circuit from corrosion, scaling and from freezing in
conditions of very low temperature, thus optimizing engine
maintenance and reliability.

Fig. 4.7

warning!
do not allow AC88 liquid to come into contact with the eyes or the skin

warning!
do not ingest any of the liquids utilised to fill the various circuits on the engine

When distilled water is used in the refrigeration circuit, an anti-freeze product must be added, otherwise the expansion of
water when it freezes may produce cracks and damage to the refrigerator unit and to the block, and in proportion to the
temperatures expected.

The anti-freezing agent manufacturer, in the package labels is giving the instructions to be followed at each case.
However, in the following box, suitable rates a reset out in accordance with temperatures:

Ant freezing liquid concentration ( %) 30 40 50 60
Freezing temperature (ºC) -10 -20 -30 -45

It is advisable the anti-freezing agent strength is selected based on a temperature which is approx. 5ºC under the actual
atmospheric temperature.

The anti-freeze solution recommended can be used fora normal operation of 2 years. At the end of this period of time the
refrigeration circuit must be emptied and cleaned, then refilled with the predetermined anti-freeze (see 4.2.2).

Run the engine for a few minutes until the cooling circuit is properly filled and free of air pockets. Check the coolant level
and replenish if necessary.

warning!
after the first 50 hours of engine duty and at six months or 1000 hours intervals thereafter, addrust inhibiting
agent AC88 to the coolant in the same proportions as indicate dearlier. The cooling liquid mixture must be
topped up with identical mixture andtotally drained and replaced every 2 years

warning!
the use of coolants that are not in conformity with the above prescriptions will cause damage to engine
components and invalidate the terms of the guarantee

ENG - 19

03917700.ENG rev. 0

4.2.3 REFUELING

Always use clean, filtered gas oil. Never use either kerosene or heavy oils. On topping up with fuel, use a funnel with a
metallic mesh filter, to keep out impurities or foreign bodies which may cause problems in the fuel injection circuit.

Whenever possible, keep the fuel tank full, as temperature changes may cause condensation of the damp air present in
the tank so that water accumulates at the bottom, giving rise to corrosion or making it impossible to start the engine if this
is aspirated by the fuel pump.

Check all tank filling plugs located at the boat deck are sealed..

warning!
Do not use dieselfuel mixed with water orany other foreingsubstances

warning!
Always use top quality fuel of certified origin. the use of dieselfuel that does not comply with the technical
specifications indicated above will cause serious damage to the injection system and hence to the engine and
also invalidate the terms of the guarantee

4.3 INSTALLATION

warning!
When water-cooled engines must be located in an enclosed place or protected by guards or a cabinet, it is
important to ensure thatcombustion air is freely supplied and freely expelled from the area

The above recommendation is of primary importance in relation to the perfect operation of the engine because the hot air that
it generates must never be routed to the area of the combustion air intake cleaner.

If the users fails to take these precautions, a hot air recirculation system will be formed thus reducing engine power output and
obstructing proper cooling.

In these cases it is advised to take steps to avoid taking in engine combustion air from the place in which the engine is
installed. This is achieved by placing the suction filter, or a suction prefilter, outside the place in which the engine is installed.

4.4 INDICATIONS FOR REMOVAL / DISPOSALOF WASTE MATERIAL

6.5 CONSERVATION

warning!
All engines not in use are subject to rusting and corrosionof machined surfaces that are not protected with a paint
coating. The degree of corrosion depends on meteoro logical changes and climatic conditions. The following
recommendations are therefore of a general nature but they will help prevent orreduce the risk of damage due torusting

6.6 LONG INACTIVITY INSTRUCTIONS

When the engine is not to be used for a long period of time or during the winter time, certain operations must be carried out to
keep it in perfect operationing condition. Follow these lay-up instructions carefully.

(1) Carefully clean the external surface of the engine.

(2) If very low temperatures are expected, always use liquid anti-freeze in the refrigeration circuit as indicated in section

4.2.2 of this manual.

(3) In the case of low-capacity fuel tanks, drain completely and clean; refill with a mixture of diesel oil and rust inhibitor

oil. For diesel oil in large-capacity fuel tanks, it is enough to add 2% rust inhibitor oil.

(4) Close the sea-water cock. Connect a hose from the sea water pump to a open bucket. Put 30% anti-freeze mixture to

the bucket. Start the engine for a moment. So the sea water system will be filled with anti-freeze mixture. Stop the
engine.

(5) Use a dielectric spray on the electrical connections, disconnect the battery, and charge it several times during the

period of inactivity.

6.7 RESTORATION OF THE RUNNINGCONDITIONS

When starting up the engine again after winter lay-up, certain operations must be performed. Follow these steps:

(1) Fill the fuel tank with clean diesel oil. Carry out the process for checking the fuel filter. If the filter is clogged, replace

the filter cartridge. The diesel oil-rust inhibitor oil mixture placed in the tank for winter lay-up can be used to operate
the engine.

(2) Drain the rust inhibitor oil contained in the crankcase and refill the engine sump with oil according to the instructions

on heading 4.2.1.1.

(3) Check the condition of the fresh-water cooling system rubber hoses.

(4) Reconnect the battery and apply a layer of neutral Vaseline to the battery terminals.

(5) Remove the nozzle supports and clean them. If possible, verify the setting of the nozzles at a workshop. Turn the

engine without nozzles, using the starter motor, to eliminate the rust inhibitor oil used in the winter. Then install the
clean nozzles.

(6) Connect the cooling and exhaust system. Open the sea-water cock.

(7) Verify whether there are any leaks in the fuel and water systems.

MINI55 air filter, cleaning instructions (use part no. 17710013):

First pre-cleaning the filter. Tap the filter to dislodge any loose dirt, then gently brush with a soft bristle brush. Use the
spray cleaner liberally onto the filter media and left soak for 10 minutes. Large the filter can be rolled or soaked in a
shallow pan of air filter cleaner. Then, remove immediately and let soak for approximately 10 minutes. Rinse off the
cotton filter media with low-pressure tap water. Rising from the clean side to the dirty side. After rising, shake off all
excess water, and dry naturally. The use of other cleaning or drying methods will damage the filter and void the air filter
warranty. After filter is completely dry, oiling (using the spray or squeeze bottle) along each pleat, once only, holding
nozzle 3 seconds away from filter media.

Carefully apply oil on any visible white spots and let sit for 20 minutes. Wipe the gasket or sealing surface with a clean
cloth or paper towel to remove excess oil, prior to installation. DO NOT OVER-OIL AIR FILTER. Over-oiling may
interfere with the proper performance of the engine and/or certain engine components.

(13) Check condition of sea water pump impeller and its eventual

replacement:

Driving impeller is neoprene and cannot rotate dried. If operated
without water, the impeller can be broken. It is important therefore
that a spare impeller is always available.

To change the impeller, close water inlet cock, remove pump
cover and with two screwdrivers prize it by removing the impeller
from the shaft. Clean housing and replace with a new one. Fit
cover by placing a new seal (Fig. 7.9). Open bottom cock. If the
impeller is broken, when it is changed, be sure all the rubber
residues scattered are removed from the water pipes.

Fig. 7.8

(14) Check alternator and starting motor:

The engine has an alternator of 12V and 40 or 50 Amps, according to the model, with an electric regulator incorporated
and an output for the revolutions counter.

Regularly check the electrical connections, its relevant positioning and the good terminal contact. For the starting motor,
check brush wear and switch sour face roughness. Replace if the service limitation has been reached.

(15) Cleaning the fuel tank:

Drain out the contains of the fuel tank to remove condensate and any foreign materials. Wash the tank with fuel (dispose
of fuel as described in heading 4.4.

(16) Replace alternator belt:

Fully detension old belt so that ist removal can be made easier
(Fig. 7.9).

When the belt is unfitted, check the condition of the pulley
recesses, they shall be dry and clean. Its cleanliness is
performed with soap water (never use petrol, gas oil or similar
products).

Fit the belt taking care the belt insertion is made with the hand
but without damaging it and if required pace it with a tool at least
without any cutting edges since otherwise the belt could be
damaged and its life shortened. The belt shall be tensioned such
as is previously explained.

(18) Inspect injection pump:

The fuel injection pump is one of the most relevant components of a diesel engine and therefore its handling requires the
best care. In addition, the injection pump has carefully been adjusted at factory and should never be adjusted carelesly.
Said adjustment, whenever is required, shall be made by a SOLÉ DIESEL licensed service shop, since a precision pump
monitor and skill knowledge are required.

The requirements for the handling of a fuel injection pump are the following: Always use fuel which is without impurities
and fuel filter shall be changed at the scheduled time.

(19) Fuse:

The switchboard carries as protection a 2 fuses: one with a size 10A to protect the panel’s instruments and other to
protect the circuit. In case the switchboard does not received power supply check if the switchboard is or not fused and
replaced.

(20) Checking and clearing turbo-charger.

To extend turbocharger life and efficiency, some basically
important instructions are given below

(1) Posible causes of turbo-charger trouble are essentially
three:

(a) Lack of lubricant: causes bearing failure with consequent
seizure of rotary components.

(b) Introduction of foreing matter: poor servicing of air cleaner
will involve the introduction of solid particles which will damage
the compressor-impeller blades. Fragments would be carried
to the cylinders.
(c) Lubricant contamination: this causes scoring of journal
bearings, clogs oil passages, wears the seals, with consequent
leakages and seizdures.

(2) Turbocharger construction siplicity is only apparent: in fact
many of its parts are machined to 1/1000 mm tolerances. Its
therefore recommended that you entrust any servicing to
skilled personnel having availability of special equipement
provided by the service network.

(3) Preventive maintenance will extend the life and efficiency of
the turbocharges. Should you notice loss of lubricant,
vibrations or abnormal noises, stop engine immediatelly.
Timely servicing will avoid costly and unexpected repairs.

(4) When the turbocharger is not working properly or for
preventive overhaul proceed as follows:

Fig. 7.10

(a) Remove turbocharger from the engine.

(b) Disassemble aluminium body enclosing main motor.
(c) Immerse complete assy in petrol (gasoline) untill all dirt is dissolved.
(d) Assist through cleaning by using a plastic brush or scraper.
(e) Wipe and dry in air making sure that the oil ducts are perfectly clean. It is better not to use steam which might
damage the bearings and the shaft.
(f) Make sure that the intake filter is perfectly clean.

NOTE: Every time turbocharger is disassembled and before starting it, make sure to prime it with engine oil to prevent

damage due to dry running.

Warning
For better lubrication of the turbocharger we advice to let the engine run at idling speed without load during 30 seconds
after starting and 3 minutes before stopping

9.0 OIL SPECIFICATIONS

9.0.1 ENGINE OIL TO BE USED

Use Sole Diesel SAE 15W/40 oil. Its service classification is as follows: as follows:

OIL VISCOSITY:

Select oil viscosity most suitable for the atmospheric temperatures on
which the engine should be operated. Its recommended to use Sole
Diesel SAE 15W/40 oil in all the seasons due to the minimum change
in its viscosity with the temperature changes. This is an all-season oil
for temperatures ranging between -15ºC and +35ºC

9.0.2 GEARBOX OIL

For mechanical geared RONIM-V and SMI-R2 and SMI-R3 gearboxes, it is recommended to use the same type of oil that is
used in the engine, a Sole Diesel SAE 15W/ 40, excepting the following models indicated in the table below.

Attention!

Exist different gearboxes of type RONIM-V and SMIR2, which is necessary use oil type ATF. Gearboxes type SMIR3,
use oil type ATF. These new units are identified with a red label near the oil level stick, as shown in the picture (Fig A,

Fig B).
