Bleeding the fuel system:
To avoid damage to the diesel engine, the fuel
filter must be drained at the drain valve from
time to time depending on the water content in
the fuel.
Purging of the fuel system is performed by
starting the Diesel engine. For this, several
starting attempts may be necessary. The
starting process may last 20 seconds as a
maximum; otherwise, the starter winding
will be overheated and destroyed. There
must be pauses of a minimum of one
minute between the individual starting
processes in order to allow the starter to
cool down.
