2.4 Oil
2.4.1 Engine oil Important The engine may be damaged if operated with improper oil level. Do not exceed the MAX level because a sudden increase in engine rpm could be caused by its combustion. Use only the recommended oil to ensure adequate protection, efficiency and service life of the engine. The use of lubricants other than recommended may shorten the engine life. Viscosity must be appropriate to the ambient temperature to which the engine is to be exposed (Par. 2.4.1.1). Danger Prolonged skin contact with the exhausted engine oil can cause cancer of the skin. If contact with oil cannot be avoided, thoroughly wash your hands with soap and water as soon as possible. For the exhausted oil disposal, refer to the Par. 6.9. 2.4.1 SAE oil classification In the SAE classification, oils are identified according to viscosity without considering any other qualitative characteristic. The code is composed of two numbers, which indicate, and must correspond to, the ambient temperature in which the engine operates, the first number refers to the viscosity when cold, for use during winter ("W"), while the second number is for viscosity at high temperatures.

2.5 Fuel
Important Use of other types of fuel could damage the engine. Do not use dirty diesel fuel or mixtures of diesel fuel and water since this will cause serious engine faults. Any failures resulting from the use of fuels other than recommended will not be warranted. Warning Clean fuel prevents the fuel injectors from clogging. Immediately clean up any spillage during refuelling. Never store diesel fuel in galvanized containers (i.e. coated with zinc). Diesel fuel and the galvanized coating react chemically to each other, producing flaking that quickly clogs filters or causes fuel pump and/or injector failure. 2.3 FUEL COMPATIBILITY EN 590 (biodiesel content max. 7% (V/V)) ASTM D 975 Grade 1-D S15 ASTM D 975 Grade 2-D S15 NATO F-54, equivalent to diesel fuel in accordance with EN 590 EN 590 or ASTM D 975 Grade 1, 2 -D S15 Arctic Diesel JIS K 2204 No. 1, No. 2 NOTE: In a warranty case the customer must prove by a certificate from the fuel supplier that an allowed fuel was used. KDI Mechanical Injection Tier 3 – Stage IIIA certified Engines (w and w/o EGR) Those engines are designed for fuels in accordance with EN 590 and ASTM D975 for a cetane number of at least 45. Since those engines are not equipped with exhaust gas after-treatment, they can be operated with diesel fuels with sulfur content up to 500 mg/kg (ppm). Compliance with the emission requirements is guaranteed only with sulfur content up to 15 mg/kg (ppm).Engines operated with fuels as per EN 590 and ASTM D975 with sulfur content < 15mg/kg have an oil changing interval of 500hrs. Fuels with a sulfur content > 500 mg/kg demand a shorter lubricating oil change interval. This is set at 250hrs. However, the engine oil must be changed when the Total Base Number TBN is reduced to 6.0 mgKOH/g test method ASTM D4739. With high fuel sulfur content fuel this may happen at 125hrs. Do not use low SAPS oils. KDI Mechanical Injection Uncertified Engines (no EGR Engines) Those engines are designed for fuels in accordance with EN 590 and ASTM D975 for a cetane number of at least 45. Since those engines are not equipped with exhaust gas after-treatment, they can be operated with diesel fuels with sulfur content up to 2000 mg/kg (ppm).Engines operated with fuels as per EN 590 and ASTM D975 with sulfur content < 15mg/kg have an oil changing interval of 500hrs. Fuels with a sulfur content > 500 mg/kg demand a shorter lubricating oil change interval. This is set at 250hrs. However, the engine oil must be changed when the Total Base Number TBN is reduced to 6.0 mgKOH/g test method ASTM D4739 2.5.1 Fuel for low temperatures When operating the engine in ambient temperatures lower than 0 degrees C, use suitable low temperature fuel normally available from fuel distributors and corresponding to the specifications of Tab. 2.3. These fuels reduce the formation of paraffin in diesel at low temperatures. When paraffin forms in the diesel, the fuel filter becomes blocked interrupting the flow of fuel. 2.5.2 Biodiesel fuel Fuels containing 10% methyl ester or B10, are suitable for use in this engine provided that they meet the specifications listed in the Tab. 2.3. DO NOT USE vegetable oil as a biofuel for this engine. 2.4 BIODIESEL COMPATIBILITY Biodiesel according to EN 14214 (only permissible for mixture with diesel fuel at max. 10% (V/V)) US biodiesel according to ASTM D6751 – 09a (B100) (only permissible for mixtures with diesel fuel at 10% (V/V)) 2.5.3 Synthetic fuels: GTL, CTL, BTL, HVIt is a well-known fact that engines which are operated for longer periods with conventional diesel fuel and then converted to synthetic fuels suffer shrinkage of polymer seals in the injection system and thus fuel leaks. The reason for this behavior is that the aromatic-free synthetic fuels can lead to a change in the selling behavior of polymer seals.Therefore, conversion from diesel fuel to synthetic fuel may only be done after changing the critical seals. The problem of shrinkage does not occur when an engine was operated with synthetic fuel from the start. 2.5.4 Non-Road Fuels Other non-road fuels may be used if they comply with all the limit values of EN 590 except for the fuel density, the cetane number and the sulfur content. The following limits apply for these parameters: 2.5 FUEL PARAMETER UNIT LIMIT VALUE Cetane number Min. 49 Fuel density at 15°C Kg/m3 820 - 860 Sulfur content mg/kg or ppm max. 500 2.5.5 Jet FuelsOnly for KDI Mechanical Injection Uncertified Engines (no EGR Engines).The following jet fuels can be used but only adopting an additional fuel filter with lubricity doser: 2.6 FUEL F-34/F-35 (kerosene, NATO designation) JP-8 (kerosene, US military designation) F-44 (kerosene, NATO designation JP-5 (kerosene, US military designation) F-63 (kerosene, NATO designation, equivalent to F-34/F-35 with additives) Jet A (kerosene for civil aviation) F-65 (kerosene, NATO designation, 1:1 mixture of F-54 and F-34/F-35) Jet A1 (kerosene for civil aviation) 2.5.6 Emission-Related Installation InstructionsFailing to follow the instructions in the applications guidebook when installing a certified engine in a piece of nonroad equipment violates federal law (40 CFR 1068.105(b)), subject to fines or other penalties as described in the Clean Air Act.OEM must apply a separate label with the following statement: “ULTRA LOW SULFUR FUEL ONLY” near the fuel inlet.Ensure you are installing an engine appropriately certified for your application. Constant speed engines may only be installed on constant speed equipment for constant speed operation.If you install the engine in a way that makes the engine's emission control information label hard to read during normal engine maintenance, you must place a duplicate label on the equipment, as described in 40 CFR 1068.105.
2.6 Coolant recommendation
A mixture of 50% demineralized water and 50% low silicate ethylene glycol based coolant liquid must be used.Use a Long Life or Extended Life Heavy Duty OAT coolant free of: silicates, phosphates, borates, nitrites and amines. The following ethylene-glycol based engine coolant for all models within KDI engine family may be used: OAT (Organic Acid Technology) Low Silicate: ASTM D-3306 D-6210 HOAT (Hybrid Organic Acid Technology) Low Silicate: ASTM D-3306 D-6210 The above coolants in concentrated formulation must be mixed with distilled, deionized, or demineralized water. A pre-mixed formulation (40-60% or 50-50%) can be used directly when available. Important Do not mix ethylene glycol and propylene glycol based coolants. Do not mix OAT and HOAT based coolant. OAT performance life can be drastically reduced if contaminated with nitrite-containing coolants. Never use automotive-type coolants. These coolants do not contain the correct additives to protect heavy – duty diesel engines. OAT coolants are maintenance free up to 6 years or 6000hrs of operation , provided that the cooling system is topped up using the same type of coolant. Do not mix different coolant types. Test the coolant condition annually with coolant test strips.HOAT are not all maintenance free and it is recommended to have SCA (Supplemental Coolant Additives) added at the first maintenance interval.

3.2 General remarks
3.2.1 Note for OEM/installer When installing the KDI engines, always bear in mind that any variation to the functional systems may result serious failures to the engine. Install the engine by strictly following the installation manual. Any changes in the installation procedure or engine must be approved by Lombardini Marine. Failure to do so shall not hold it responsible for operation malfunctions and any damage to the engine. 3.2.2 Note for end user The following indications are dedicated to the user of the machine in order to reduce or eliminate risks concerning engine operation and the relative routine maintenance work. The user must read these instructions carefully. Failure to do this could lead to serious danger for his personal safety and health and that of any persons who may be in the vicinity of the machine. Make sure transmission is in neutral on ignition. The engine must not operate in places containing inflammable materials, in explosive atmospheres, where there is dust that can easily catch fire unless specific, adequate and clearly indicated precautions have been taken and have been certified for the machine. Children and animals must be kept at a due distance from operating machines in order to prevent hazards deriving from their operation. Thoroughly wash and clean all the external parts of the engine before performing any operation, in order to avoid the accidental introduction of impurities/foreign bodies. Use only water and/or appropriate products to clean the engine. If cleaning engine with a pressure washer or steam cleaner, it is important to maintain a minimum distance of at least 200mm between the surface to be washed and the nozzle. Avoid directing the nozzle on electrical components, cable connections and sealed rings (oil seals etc). Thoroughly wash and clean the area surrounding the engine following the instructions provided by machine manufacturer. Fuel and oil are inflammable. The tank must only be filled when the engine is off. Before starting, dry any spilt fuel. Fuel vapour is highly toxic. Only refuel outdoors or in a well ventilated place. Do not smoke or use naked flames when refuelling. During operation, the surface of the engine can become dangerously hot. Avoid touching the exhaust system in particular. Before proceeding with any operation on the engine, stop it and allow it to cool. Always open the radiator plug or expansion chamber with the utmost caution, wearing protective garments and goggles. The coolant fluid is under pressure. Never carry out any inspections until the engine has cooled. The oil must be drained whilst the engine is hot. Particular care is required to prevent burns. Do not allow oil to come into contact with the skin because of the health hazards involved. It is recommended to use an oil intake pump. During operations that involve access to moving parts of the engine and/or removal of rotating guards, disconnect and insulate the negative wire (-) of the battery to prevent accidental short-circuits and to stop the starter motor from being energized. Check belt tension only when the engine is off. Fully tighten the tank cap each time after refuelling. Do not fill the tank right to the top but leave an adequate space for the fuel to expand. To start the engine follow the specific instructions provided in the engine and/or machine operating manual. Do not use auxiliary starting devices not originally installed on the machine (e.g. Startpilot). Before starting, remove any tools that were used to service the engine and/or machine. Make sure that all guards have been refitted. Do not mix fuel with elements such as oil or kerosene. Failure to comply with this prohibition will cause the non-operation of the catalyst and non-observance of the emissions declared by Lombardini Marine. Pay attention to the temperature of the oil filter when the filter itself is replaced. Only check, top up and change the coolant fluid when the engine is off and reached the ambient temperature. Coolant fluid is polluting, it must therefore be disposed of in the correct way. Do not use air and water jets at high pressures on cables, connectors and injectors. Important Only use the eyebolts A installed by Lombardini Marine to move the engine (Fig. 3.1). The angle between each lifting chain and the eyebolts shall not exceed 15° inwards. The correct tightening of the lifting screws is 25 Nm. Do not interpose spacers or washers between the eyebolts and engine head. Fig. 3.1

Never operate the engine with covers, shrouds, or guards removed. LETHAL EXHAUST GASES Carbon Monoxide can cause severe nausea, fainting or death. Avoid inhaling exhaust fumes and never run the engine in a closed building or confined area. Carbon monoxide is toxic, odorless, colorless, and can cause death if inhaled. ELECTRICAL SHOCK Electrical Shock can cause injury. Do not touch wires while engine is running. HIGH PRESSURE FLUID RISK OF PUNCTURE High Pressure Fluids can puncture skin and cause severe injury or death. Do not work on fuel system without proper training or safety equipment. Fluid puncture injuries are highly toxic and hazardous. If an injury occurs, seek immediate medical attention. EXPLOSIVE FUEL Explosive fuel can cause fires and severe burns. Fuel is flammable and its vapours can ignite. Store fuel only in approved containers, in well ventilated, unoccupied buildings. Do not fill the fuel tank while the engine is hot or running, since spilled fuel could ignite if it comes in contact with hot parts or sparks from ignition. Do not start the engine near spilled fuel. Never use fuel as a cleaning agent. EXPLOSIVE GAS Explosive Gas can cause fires and severe acid burns. Charge battery only in a well ventilated area. Keep sparks, open flames, and other sources of ignition away from the battery at all times. Batteries produce explosive hydrogen gas while being charged. Keep batteries out of the reach of children. Remove all jewelry when servicing batteries. Before disconnecting the negative (-) ground cable, make sure all switches are OFF. If ON, a spark will occur at the ground cable terminal which could cause an explosion.
3.5 Safety and environmental impact
Every organisation has a duty to implement procedures to identify, assess and monitor the influence of its own activities (products, services, etc.) on the environment. Procedures for identifying the extent of the impact on the environment must consider the following factors: Liquid waste. Waste management. Soil contamination. Atmospheric emission. Use of raw materials and natural resources. Regulations and directives regarding environmental impact. In order to minimise the impact on the environment, Lombardini Marine now provides a number of indications to be followed by all persons handling the engine, for any reason, during its expected lifetime. - All components and fluids must be disposed of in accordance with the laws of the country in which disposal is taking place. - Keep the fuel and engine control systems and the exhaust pipes in efficient working order to limit environmental and noise pollution. - When discontinuing use of the engine, select all components according to their chemical characteristics and dispose of them separately.

5.7 Product preservation
Important If the engines are not to be used for 6 months, they must be protected by carrying out the operations described in Engine storage (up to 6 months) (Par. 5.8). If the engine is still not in use after the first 6 months, it is necessary to carry out a further operation to extend the protection period (more than 6 months) (Par. 5.9). If the engine is not to be used for an extended period, the protective treatment procedure must be repeated within 24 months of the previous one.
5.8 Engine storage (up to 6 months)
Before storing the engine check that: The environments are not humid or exposed to bad weather. Cover the engine with a proper protective sheet against dampness and atmospheric contaminants. The place is not near electric panel. Avoid storing the engine in direct contact with the ground.
5.9 Engine storage (over 6 months)
Follow the steps described in Par. 5.8. Engine oil replacement (Par. 6.1). Refuel with fuel additives for long storage. With expansion tank: make sure that the coolant is up to the maximum level. Without expansion tank:Follow the steps described in Par. 4.7. Start the engine and keep it idle at minimum speed for 2 minutes. Bring the engine to 3/4 of the maximum speed for 5÷10 minutes. Turn off the engine. Completely empty the fuel tank. Spray SAE 10W-40 on the exhaust and intake manifolds. Seal the exhaust and intake ducts to prevent foreign bodies from entering. When cleaning the engine, if using a pressure washer or steam cleaning device, avoid directing the nozzle on electrical components, cable connections and sealed rings (oil seals etc). If cleaning engine with a pressure washer or steam cleaner, it is important to maintain a minimum distance of at least 200mm between the surface to be washed and the nozzle - avoiding absolutely electrical components such as alternators, starter motors and engine control units (ECU). Treat non-painted parts with protective products. If the engine protection is performed according to the suggestions indicated no corrosion damage should occur.
5.10 Engine starting after storage
Remove the protective sheet. Use a cloth soaked in degreasing product to remove the protective treatment from the external parts. Inject lubricating oil (no more than 2 cm3) into the intake ducts. Refill the tank with fresh fuel. Make sure that the oil and the coolant are up to the maximum level. Start the engine and keep it idle at minimum speed for a two about minutes. Bring the engine to 75% of maximum rated speed for 5 to 10 minutes. Stop the engine while the oil is still hot (Par. 6.1), discharge the protective oil in a suitable container. Warning Over time, lubricants and filters lose their properties, so it is important consider whether they need replacing, also based on the criteria described in Tab. 5.2. Replace the filters (air, oil, fuel) with original spare parts. Pour new oil (Par. 4.5) up to the maximum level. Empty the cooling circuit completely and pour in the new coolant up to the maximum level (Par. 6.5).
