Water in Fuel
If the EVC system warns for too much water in the fuel
filter, the water separator needs emptying.
IMPORTANT!
Do not continue operating if there is water in the water
separator, it can damage the engine.
Draining the fuel filter
1 Stop the engine and remove the ignition key from
the ignition lock.
2 Remove the connector piece from the water sepa-
rator (1).
3 Place a container under the fuel filter and carefully
unscrew the water separator (2). Let the water run
out. When diesel runs out, screw in the water sep-
arator until it bottoms against the filter. Then tighten
an additional 1/4 to 1/2 turn.
4 Refit the connecting piece (1).
Draining the fuel pre-filter (extra equipment)
1 Place a container beneath the fuel filter.
2 Open the bleed screw (1) on the fuel filter about 4
turns.
3 Drain the water and contaminants via the plug in the
bottom of the filter.
