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 / Stop button on the Local control
panel or by giving a start command from the
MasterView Easy, the electric system is activated, the
fuel lift pump starts pumping and the starting
procedure will begin. (The system is deactivated by
pushing the Start / Stop button on the Local control
panel again or by giving a stop command from the
MasterView Easy)
The Whisper 3.5 can even be started with an almost
discharged battery using the cylinder compression release
handle. The engine can then be rotated easily ("turned
over") as the valves are opened i.e. in the decompression
position.
Figure 10: Decompression handle
You can also use the decompression handle to readjust
the valve clearance and to fill the cooling system with anti
freeze for conservation in winter time.
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.
