Operation instructions
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
tted to these engines is a fuelled starting aid. This
electrically operated device ignites a specic amount
of diesel fuel in the induction manifold in order to
heat the induction air.
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 tted) 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.
Caution: If the engine has not run for a long period
(four weeks or more), ensure that there is lubricating
oil at the turbocharger. To do this, hold the engine
stop switch in the “STOP” position; operate the
starter motor until the oil warning light goes out or a
pressure is indicated on the oil pressure gauge.
How to start a cold engine with the fuelled
starting aid
Note: Use this method when the cylinder head
temperatures are 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.
How to stop the engine
Caution: It is recommended that a turbocharged
engine is run at a reduced load for 2-3 minutes
before it is shut down. This will allow the
turbocharger to cool.
1. Remove the load from the engine and allow the
engine to cool for 2-3 minutes.
2. Switch the engine stop switch to the stop position,
refer to the users’ handbook of the application
manufacturer..
