| Component | Maintenance | Notes and precautions |
| Lubrication system | Oil specifications | Use specified oils according to Manufacturer’s indication. |
| Oil check | Check the oil level in the crankcase daily or before each start-up to ensure that the level is in the safe range. Remove the dipstick and wipe the end clean, reinsert as far as possible, and remove. Maintain the oil level between the marks (Min and Max). |
|
| Oil change | For the oil change remove the draining hose from its holder. Position the hose in the oil collecting container. Remove the oil filling plug. Open the oil draining valve located on the engine and drain the oil completely in the container. Change oil according to intervals suggested by the Manufacturer. Do not mix different oils. |
|
| Oil check | Remove the oil filter by turning it counter clockwise by means of a suitable wrench. Apply a thin layer of oil to the rubber seal of the new filter. Replace the oil filter according at time intervals recommended by the Manufacturer. | |
| Fuel system | Cleaning and replacement Cleaning and replacement |
Replace fuel pre-filter at time intervals recommended by the Manufacturer. Close the fuel supply valve. Loosen the fuel filter by turning it counter clockwise. Remove the filter and clean the contact surface. Tighten the filter on the adapter until the seal comes in contact. Replace fuel filter within the intervals indicated by the Manufacturer. |
| Cooling system | Cleaning / replacement of the air cleaner | Release the two spring clamps and remove the cover of the air intake. Clean the cover and the base with a clean cloth so as to remove the dirt. Refit the filter and the cover at the base of the filter air intake. Replace the filter at time intervals recommended by the Manufacturer. |
| Cooling liquid top up | Before filling the cooling system stop the generator and let it cool down. Close the draining taps. In order to discharge the pressure turn slowly the plug clockwise up to the first stop. Remove the plug after the pressure has been completely released. |
|
| Sea water strainer | At least once a week check for the correct water flow through the strainers. At least once a month check the integrity of the strainers. At least once a month clean the suction strainer. At least once every six months check the condition of the cover seal. |
Recover all waste materials (engine oil, fuel, filter, etc..) according to the rules in force concerning the special waste disposal.
Hot coolant and steams may cause heavy injuries or even death.
Failure to observe the oil specifications may cause inadequate lubrication/oil pressure and cold-starting difficulties.
If the oil level is not positioned between the two reference notches do not activate any device.
Pay special attention to the coolant level. After the coolant drains, allow coolant to completely refill the engine water jacket. Check the coolant level as prescribed in the Pre-start Checklist.
Damage due to sea water. Sea water quickly deteriorates metals.
Wipe up sea water on and around the generator set and remove salt deposits from metal surfaces.
Do not add coolant if the engine is still hot. Adding coolant to an hot engine can cause the cylinder block or cylinder head to crack. Wait until the engine has cooled down.
