7 Maintenance
Bleeding the fuel system
If the fuel tank has been run empty, or after having performed
maintenance on the fuel system (for example filter replacement, water
separator cleaned, etc.), the fuel system bleeds itself automatically when
starting the engine.
Checking/cleaning the additional fuel filter (water separator, option)
Drain the condensation water in the fuel prefilter at the latest if indicator
light 67
on the instrument panel illuminates.
Drain water more frequently at temperatures around or below 0 °C/32 °F,
otherwise problems can arise even if winter diesel is used.

Rotating parts in the engine compartment can cause serious injury.
