How to start the engine
Use only this procedure to start the engine; it has been designed to protect the engine and the environment.
Several factors affect engine start, for example:
• The power of the batteries
• The performance of the starter motor
• The viscosity of the lubricating oil
• The installation of a cold start system.
Diesel engines need a cold starting aid if they are to start in extremely cold conditions. These engines are fitted
with glow plugs as standard and are only necessary in ambient temperatures colder than -5ºC
Before the engine is started the operator should understand fully the controls and their use.
Preparations for an engine start
1. Ensure that there is more than enough fuel in the tank 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, and in the reverse gearbox.
7. Ensure that the control lever for the reverse gearbox is in the neutral position. .
How to start a cold engine in cold conditions
Caution: Ether type fuels must not be used.
Note: Use this method when the ambient temperature is colder than -5
O
C (23
O
F).
1. Switch on the electrical system.
2. Check that the reverse gearbox is in neutral. Adjust the engine speed control to the minimum speed
position.
3. Hold the lever of the heat/start switch in the up position for 15 seconds. Hold the lever of the heat/start
switch in the down position to engage the starter motor. When the engines starts, release the lever. Adjust
the engine speed control to give an even idle.
4. Check that water comes out of the end of the exhaust pipe or out of the separate discharge outlet.
5. If the engine does not start in 15 seconds, allow the starter motor to cool for 30 seconds. When the
engine has started, adjust the engine speed control to get an even idle speed. 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.
How to start a warm engine, or if the ambient temperature is hotter than -5°C (23°F).
1. Switch on the electrical system.
2. Check that the reverse gearbox is in neutral. Adjust the engine speed control to the minimum speed
position.
3. Hold the start switch down to engage the starter motor. When the engine starts, adjust the engine speed
control to give an even idle speed. 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:
Do not run the electric fuel lift pump for more than 60 seconds without fuel. The fuel pump can be
permanently damaged as it relies on the fuel for lubrication.
