| Component | Maintenance | Notes and precautions |
| Lubrication system | Replacement of the oil separator filter | Replace the separator filter, according to the rime intervals suggested by the manufacturer. |
| Oil level check | Check the oil level by means of the special control rod; make sure the level is included in the allowable range (MIN - MAX). Do no start the engines if the oil level is not included between the two reference marks, as indicated in the Manufacturer’s Manual. | |
| Oil and oil filter replacement |
Replace engine oil according to time intervals and oil type suggested by the Manufacturer. | |
| Fuel system | Fuel filter replacement |
Replace fuel filter within the intervals indicated by the Manufacturer. |
| Air cleaner replacement | Replace air filter within the intervals indicated by the Manufacturer. | |
| Cooling system | Coolant check | Make sure the coolant is in the tank (lever sensor, reference plate, built-in eyelet). |
| Cooling system filling | For coolant features refer to the User’s Manual of the Manufacturer. | |
| Cooling system drainage | Drain the coolant only when the engine is stopped; follow the procedure indicated by the Manufacturer. |
DANGERA wrong use, a wrong maintenance, tampering and replacement of pieces, can cause serious damages or mortal events, beyond damaging the equipment.
The interventions on the electrical and mechanical equipment must be carried out by qualified staff after having examined the Manual delivered by the Manufacturer.
ENVIRONMENTDispose of waste materials (engine oil, fuel, filters, etc..) with respect for the environment and according to the laws in force.
Use only authorized disposal procedures, in case of doubts, contact the Port Authority.
DANGERAny maintenance procedure on the engines is to be carried out with engines shut OFF, after they have sufficiently cooled down and after seeing to the prevention of their being switched on by disconnection of the magneto-thermal switches.
CAUTIONUse only approved fuels, otherwise the Manufacturer’s warranty will become null and void.
CAUTIONDo not top up oil so to exceed the MAX notch of the control rod.
If the oil level is too high, damage to the engines may occur!
CAUTIONDo not use open flames, do not generate electric sparks.
Do not smoke. Avoid ignition sources. Risk of fires and explosions!
DANGERCompressed air at high pressure may create the risk of injuries. Do not direct compressed-air jets at persons. Wear protective goggles, safety masks and ear protectors.
DANGERHot oil can contains combustion residues which are harmful to health.
Risk of injury and scalding! Wear protective clothing, gloves and goggles/safety mask. Avoid contact with skin. Do not inhale oil vapour.
DANGERBecause of the high temperature in the engine room, oil or fuel leaks can evaporate and create a serious risk of fire.
Regularly check the integrity of the system.
CAUTIONIt is absolutely necessary to view with RIVA the documentation of the different components provided by the Manufacturer; for any problem relevant to the use or maintenance, please directly refer to the Service Centres, listed in the documentation provided by the Manufacturer. In any case there are some small procedures that can be carried out by the crew on board, after consulting the operation manual.
ENVIRONMENTHandle used fuel filters as special waste.
DANGERCoolant is hot and under pressure. Risk of injury and scalding! Let the engine cool down and wear protective clothing, gloves, goggles and safety mask.
CAUTIONCold coolant in a hot engine causes thermal stress with the risk of formation of cracks in the components. Fill/top up only a cold engine.
CAUTIONIf the oil level is not positioned between the two reference notches do not activate any device.
