NOTE
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 1
minute between the individual starting processes in order to
allow the starter to cool down.
The fuel prefilter must be drained at the drain valve [A] from time to time
depending on the water content in the fuel.
