flowing out of the nipples is free of air bubbles. This may take around
130-150 pump strokes.

- Continue hand pumping until it feels tight.
• After renewing the fuel filter, it will take approximately 20 strokes.
• Approx. 50 pump strokes after renewing a unit injector.

Important!
The starter motor may only be used for 30 seconds at a time.
After that time it must rest for 2 minutes.
If the engine fails to start after bleeding:
- Open the bleed nipples again and pump the hand pump until fuel
without air bubbles flows out.
- Tighten the bleed nipples. Start the engine and check for leaks.
Use a container to avoid spills
