Bleeding the fuel system
WARNING!
If the fuel, as it drains, comes into contact with hot engine parts or the exhaust
system, there is an increased risk of fire
☞
Never bleed the fuel system if the engine is hot!
Bleed the fuel system in the following cases:
•
After removing and fitting the fuel filter and the fuel lines back on again, or
•
After running the fuel tank empty, or
•
If the fuel system leaks with the engine running, or
•
After running the engine again, after it has been out of service for a long period of time
☞
Bleed the fuel system as follows:
•
Fill the fuel tank
•
Unscrew the vent screw 135/1 on the side of the fuel injection pump
•
Actuate the hand pump lever on the fuel supply pump 135/2until the fuel runs out free
of air from the bleed opening
•
Tighten bleed screw 135/1
•
Turn the ignition key to the “ON” position (1)
•
Turn the starter until the engine starts (15 seconds maximum)
If the engine runs smoothly for a while, and then stops; or if it does not run smoothly:
•
Check once again if there is any air in the fuel system
The presence of air in the fuel system is a sign of leakage on the low-pressure side of the
fuel system!
•
Switch off the engine
•
Turn the ignition key to the “OFF” position (0)
