How to start the engine
Several factors affect engine start, for example:
• The power of the battery
• The performance of the starter motor
• The viscosity of the lubricating oil
• The installation of a cold start system
• Size of the starter cables.
Diesel engines need a cold starting aid if they are to start in very cold conditions. The cold start aid fitted
to these engines are glow plugs, which are fitted into the combustion chamber of each cylinder and are
connected electrically. These engines will start without the aid to temperatures of -10oC (13oF). However, 10
seconds of pre-heat gives a smooth start at temperatures colder than -10oC (13oF).
Preparations for an engine start
1. Ensure that there is more than enough fuel available for the voyage.
2. Ensure that the fuel supply control (if fitted) is in the open position.
3. Check that the seacock strainer is clean.
4. Open the seacock.
5. Check the amount of coolant in the header tank.
6. Check the amount of lubricating oil in the sump.
How to start a cold engine with the fuelled starting aid
Note: Use this method when the cylinder head temperatures are below approximately 0°C (32°F).
1. Switch on the electrical system.
2. Hold the heat switch in the down position for 15 seconds. Press the start button to engage the starter
motor. When the engine starts, release the heat switch. The engine will run up to the set speed, 1500 or
1800 rev/min.
3. If the engine does not start in 15 seconds, hold the heat switch down for 10 seconds and engage the
starter motor again. When the engine has started, release the heat switch. Check that water comes out of
the end of the exhaust pipe or out of the separate discharge outlet.
Always ensure that the engine and starter motor are stationary before the starter motor is engaged again.
Caution:
Ether type starting aids must not be used at the same time as the fuelled starting aid.
How to start a warm engine
1. Switch on the electrical system.
2. Press the start button to engage the starter motor. When the engine starts it will run up to the set speed,
1500 or 1800 rev/min. Check that water comes out of the end of the exhaust pipe or out of the separate
discharge outlet.
Always ensure that the engine and starter motor are stationary before the starter motor is engaged again.
