Before you start

  • Do not smoke when you drain liquids from engine or filters.
  • Keep open fire away from the location.
  • Remove any spilled oil or liquids before starting the engine.
  • A water separator does not belong to the standard scope of supply, but must be procured and fitted nonetheless.

Procedure

  1. To drain the water separator: Open the drain plug at the bottom of the filter housing.
  2. Drain the water and collect it in a bowl.
  3. Close the drain plug.
  4. After having drained the water separator/fuel filter, the fuel system must be freed from air (bled).
  5. The fuel system is self-bleeding: Turn the key in the start switch in the ON position and after about 1 minute the fuel lift pump will begin to operate and bleed the system automatically.
