Small amounts of air introduced by changing the filters or injection pump supply line will be vented automatically, if the fuel filter is changed in accordance with the instructions. No manual bleeding of fuel lines is required. However, manual bleeding will be required if: ! The fuel filter is not filled prior to installation. ! The injection pump has been replaced. ! High pressure fuel lines have been replaced. ! Machine has run out of fuel. (Fuel tank has run empty) For bleeding procedures Refer to section on replacing fuel filter.
