7.4 START OF PROPULSION ENGINES

First start-up
Read the manufacturer’s specific documentation carefully before starting up a new or overhauled engine.

During the first hours of operation, it is recommended that new engines be operated at a maximum of three quarters of their maximum load and at vary-ing speeds.

After this initial run-in, the engine should be brought up to full output gradually.

CAUTION

Use only approved technical fluids; otherwise the Manufacturer’s warran-ty will become null and void and the engines can get seriously damaged.

Starting up
Before daily starting the engine, check fuel level, coolant level and engine oil level and replenish, if necessary.

If the oil levels and coolant were insufficient refill inside of the expansion vessels, taking care not to exceed the index of the maximum level.

CAUTION

Engines must always be started with gear boxes at idle run and throttle levers set at minimum speed.

DANGER

Before starting an engine, ensure that nobody is staning in the dangerous area of the engine room.

Cooling liquid
The engine cooling system shall be filled with a mixture of potable water and anti-freeze based on glycoethylene or anti-corrosive. Refer to the manufacturer’s specific documentation for this purpose.

• Slowly insert the coolant into the compensation yacht through the coolant filler cap (1).
• For the amount of coolant see “Technical data” in the manuals supplied by the manufacturer.

Engine oil

CAUTION

Do not top up oil so to exceed the MAX notch of the dipstick. If the oil level is too high, damage to the engines may occur!

Sea water suction pumps

CAUTION

Do not let raw water pump run dry!
Make sure that all valves of the raw water circuit are open. Drain the pump in case of freezing danger.

Oil level check

Check engine oil level only approx. 20 minutes after the yacht has been switched off.

• Pull out dipstick (1) for oil level check.
• Wipe it with a clean, dry and lintfree cloth.
• Place it back up to retainer.
• Pull out dipstick again.

The oil level should be between the two notches in the dipstick and must never fall below the MIN notch.

Top up oil as necessary.

Ensure outmost cleanliness when handling fuels, lubricants and coolants.

CAUTION

Do not top up oil exceeding the MAX notch of the dipstick. If the oil level is too high, damage to the engines may occur!
