Extended operating instructions
Check when starting the first time or after a longer
period of rest:
1 If there is any damage caused by transport or
installation.
2 Check if installation conforms to the installation
instructions.
3 Ensure the generating set is free to turn without
obstruction.
4
Check all hoses and hose connections for leaks.
5
Check all cables and cable end terminal connections.
6
Check the engine and generator mounting bolts.
Routine "pre-start" checks:
1
Check engine oil level.
The generator switches off in the event of insufficient
oil-pressure. Even when the oil level is too low the oil
pressure can be high enough. Do not run the
generator with the oil below the lowest mark in the,
because a smaller volume of oil will become
contaminated considerably quicker than a larger
volume. Therefore we recommend daily oil-checks.
Check oil level prior to starting the engine or at least 5
minutes after the engine has stopped.
2
Check sea water cocks. Do not forget the valve of the
water outlet in case of a water/exhaust gas separator.
3
Check the water strainer.
4
Check for leaks.
5 Regularly check the siphon vent in the cooling water
supply.
6 If no Mass Systemswitch is used: Switch main Power
Source Selector switch to "OFF" or switch off all
devices.
7
Switch on the battery switch.
Starting the generator:
By pushing the start button briefly the electric system
is activated, the fuel lift pump starts pumping and the
starting procedure will begin. (By pushing the stop
button the system is deactivated)
The first time starting up or after running out of fuel it
could be necessary to prime the fuel system. (Refer to
bleeding fuel system instructions in the maintenance
chapter).
A restart protection prevents starting the engine when it is
already running, which could cause damage.
In the event of starting problems (numerous
attempts are made), close the sea-water inlet
cock while cranking to prevent the outlet
system and engine to fill up with water.
During the starting process, the cooling water pump is
driven with the engine. The cooling water is discharged to
the exhaust outlet, because the engine does not run, the
exhaust pressure is not high enough to expel this water.
Open the valve directly when the engine starts to prevent
damaging the impeller.
Water in the cylinder will cause serious damage to the
engine. For instance; a bent piston rod or a cracked
cylinder head. In fact water in the cylinder is the main
cause for engine damage in pleasure craft.
Checks once the generator is in operation:
1
Check for abnormal noise or vibration.
2
Check the voltage.
3
Check coolant flow.
Always check immediately after starting the generator
if cooling water flows at the exhaust outlet. If this is
not the case, check the cooling water pump. After
having become acquainted with the generator you will
be able to recognise the coolant flowing through the
system by listening for the noise of the water which is
expelled.
Be aware that especially in harbours the
coolant water inlet can easily be blocked by
floating objects.
4 Power source selector switch (off/shore
power/generator power). Switch to power source
generator. If a Mass Systemswitch is installed, this
operates automatically.
Before loading the generating set up to maximum,
have it run warm. The first 50 hours of running the
continuous load should be restricted to 70 % of maxi-
mum load. Running for long periods at no load or light
load in the first 50 hours can cause cylinder glazing
and high oil consumption.
