Fuel system
Fuel
If Diesel fuel which contains moisture is used the injection system and the cylinder liners / pistons will be
damaged. This can be prevented to same extent by filling the tank as soon as the engine is switched off
while the fuel tank is still warm (formation of condensation is prevented). Drain moisture from storage tanks
regularly. Installation of a water trap upstream of the fuel filter is also advisable. Do not use any additives to
improve flow properties in winter.
Injection pump
No alterations must be made to the injection pump. If the lead seal is damaged the warranty on the engine
will become null and avoid.
Faults

workshop.
