7.5 PROPULSION ENGINE MAINTENANCE

Component Maintenance Notes and precautions
Lubrication system Replacement of the oil separator filter
Replace the separator filter, according to the time intervals suggested by the Manufacturer.
Diaphragm check and replacement Check if the diaphragm is damaged; in this case replace it.
Oil level check
Check the oil level by means of the special dipstick; 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.
Check and replacement of air cleaner clogging gauge Check the condition of the gauge; if it does not reset easily, replace it with a new one. Replace the gauge according to the intervals suggested 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.
CAUTION

Use only approved fuels, otherwise the Manufacturer’s warranty will be-come null and void.

DANGER

Hot 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.

DANGER

Because 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.

CAUTION

It is absolutely necessary to view with CUSTOM LINE 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.

CAUTION

Do not top up oil in addition to the MAX mark the control rod. With a high oil level faults occur to the engine!

CAUTION

Do not use open flames, do not generate electric sparks.
Do not smoke.
Avoid ignition sources. Risk of fires and explosions!

DANGER

A 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.

ENVIRONMENT

Dispose 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.

DANGER

Any 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.

ENVIRONMENT

Handle used fuel filters as special waste.

ENVIRONMENT

Collect the liquid and dispose of according to current regulations.

CAUTION

Fill the cooling system only in a cold engine.

DANGER

Compressed 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.

DANGER

Coolant is hot and under pressure. Risk of injury and scalding! Let the engine cool down and wear protective clothing, gloves and goggles safety mask.

CAUTION

Cold 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.

CAUTION

If the oil level is not positioned between the two reference notches do not activate any device.
