Fuel system, bleeding
After a filter change the fuel system must be bled. If the
fuel tank has been run dry and after a long-term
stoppage.
IMPORTANT:
Never disconnect the pressure pipe.
1 Connect a transparent hose to the bleed nipple (1).
Feed the hose to a container to avoid spillage.
2 Open the bleeding nipple and pump fuel with the
hand pump (2) until the fuel is free from bubbles.
Close and tighten the bleed nipple.
3 Pump a further 10 times on the hand pump.
Resistance in the hand pump can feel heavy, but
this is completely normal and necessary to bleed
the system.
4 Remove the hose and fit the protective cap to the
bleed nipple.
Water in Fuel
If there is an alarm regarding “Water in fuel”, check the
water separator both on the fuel filter and the pre-fuel
filter.
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 turn off the ignition.
2 Remove the connector piece (1) from the sensor
(2).
3 Place a container under the fuel filter and carefully
unscrew the sensor (2). Let the water run out. When
diesel runs out, screw in the sensor until you feel
slight resistance. Then tighten an extra 1/4 to 1/2
turn.
IMPORTANT:
If the sensor is torqued more than 1/2 turn, the
sensor can be damaged.
4 Refit the connector piece (1).
1 Place a container beneath the pre-fuel filter.
2 Open the bleed screw (1) on the pre-fuel filter about
four turns.
3 Drain the water and contaminants via the plug in the
bottom of the filter.
4 Bleed the fuel system.
