DANGERAny maintenance intervention on the engines is to be carried out with the engines shut OFF, after they have sufficiently cooled down.
DANGERAny maintenance intervention on the engines is to be carried out with the engines shut OFF, after they have sufficiently cooled down.
DANGERDo not approach the V-belts or the engines pulleys with the hands, when the engine is running.
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.
CAUTIONOnly use the approved fluids indicated by Manufacturer, otherwise the warranty given by the Manufacturer is voided.
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.
CAUTIONIt is absolutely necessary to view together with RIVA the documentation for the different components provided by the manufacturer; for any problem relevant to use or maintenance, please contact the Service Centres listed in the documents provided by the manufacturer.
Anyway, in case of need, some little interventions can be carried out by the staff on board, after consulting the operation manual.
CAUTIONDuring navigation, regularly check the cleanliness of the sea water strainer baskets.
If the yacht is navigating in a dirty sea area, check the condition of the strainers and clean them.
Caution is very important to prevent damaging mechanical parts (engines, generator, etc..), draining systems and to prevent jeopardizing the safety of the yacht.
CAUTIONDo not tamper or try to repair the injection pump or its power unit on a diesel engine. In case the lead seal is damaged, this will void the engine warranty.
Have the injection pumps or the injectors repaired only at an authorised Service Centre.
ENVIRONMENTDispose of waste materials (engine oil, fuel, filters, etc..) with respect for the environment and according to the rules in force.
Use only authorized disposal procedures and, in case of doubts, contact the Port Authority.
| Component | Maintenance | Notes and precautions |
| Lubrication system | ||

| Oil and oil filter replacement | Replace engine oil according to time intervals and oil type suggested by the Manufacturer. | |
| Fuel system | Cleaning of fuel pre-filter | Clean the fuel pre-filter with proper diesel oil and dry it with a compressed air jet. |
| Drain of the fuel filter condensate |
Each time the engine oil is changed, open the draining plugs and have the condensate flow out until only fuel comes out. | |
| Fuel filter replacement | Replace fuel filter within the intervals indicated by the Manufacturer. | |
| Cooling system | ||
| Drain the cooling system |
Drain the coolant only when the engine is stopped; follow the procedure indicated by the Manufacturer. | |
| Filling and draining | Refill with a mixture of drink water and antifreeze on ethylene glycol basis or anticorrosion agent. | |
| V-belts | Check the belts condition | Make sure that there are no cracks, no traces of oil, no signs of overheating and no signs of wear; if so, replace them. |
| Check the tension | Use the proper gauge supplied by the Manufacturer to measure the belt tension. |
|
| Replacement of v-belts | Replace the v-belts at the intervals recommended by the Manufacturer. |
