2 Check coolant in both expansion tanks.
3 Check for leakages.
4 If no Mass Systemswitch is used: Switch main Power
Source Selector switch to "OFF" or switch off all
devices.
5 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.
Checks once the generator is in operation:
1 Check for abnormal noise or vibration.
2 Check the voltage.
3 Power source selector

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.
Engine load during longer operation:
Please ensure that the generating set is not overloaded.
Overloading occurs when the electrical load (demand) is so
high that the generator cannot be turned around properly by
the diesel engine. Overloading causes the engine to run
rough, while using oil and excessive fuel and producing soot
by the exhaust. The engine can even stop.
The generator should therefore only be loaded at the
maximum rated power for short periods (2-3 hours) only!
The high peak current is meant for the ability to start
electrical devices that need a high current for starting
especially electric motors and compressors (from a still
stand state).
switch (off/external
In order to prolong the generating set's life expectancy, the
nominal electrical demand on the system should be about
70% or the rated generating set's maximum load. Please
note this when switching on your electrical devices!
Nevertheless, the W-SQ12 is designed so as not to
overheat, even under extreme conditions.
Do not run the generator for very long periods at no load or
at very low load. When this is necessary do load the
generator at least one hour in 10 hours for minimum 70%.
Long term running at too low load will cause the exhaust to
be choked by carbon.
Never remove the battery while the engine is
running or any electrical cable while the battery
is connected in the circuit. Only disconnect the
battery with the engine stopped and all
switches in "OFF" position
Stopping the generating set:
1 Avoid stopping of the generator abruptly after a long
period of operation at high load! Doing so, you avoid
unnecessary thermal load to your generating set!
Act as follows:
Prior to switching off the generating set, decrease the
generator load (i.e. turn off most electrical users) and
let the generator run at low load for approx. 5 minutes
to allow the engine to get properly cool (the influent
coolant must flow through the system in order to cool
the engine).
If the generator is operating in a hot environment and
you do not act as given above, the excessive heat in
the engine can trip the "high temp" alarms. In that case,
a restart of the engine is not possible for some time. It
is also recommended to switch off electrical users prior
to stopping the generator because of the voltage drop
that occurs as the engine comes to a halt. Such voltage
drops may cause damage to electric motors,
compressors (in refrigerators or air conditioners etc.).
2 Press the STOP button.
3 Switch to an other 230 / 400 Volt power source, if
available. If a Mass Systemswitch is installed, this is
done automatically.
