BLEEDING AIR FROM FUEL CIRCUIT

When removing and installing parts and components in the fuel circuit, or when the engine runs short of fuel, carry out air bleeding from the fuel circuit in the following manner:

1. Check that there is enough fuel remaining in the fuel tank.
2. Turn the engine starting switch to the ON position and hold it in that position for 10 to 20 seconds. The fuel feed pump is actuated and air is bled from the fuel circuit automatically.
3. Turn the engine starting switch to the START position and check that the engine starts running. If the engine does not start up, repeat the step 2 above.
