6. Loosen the union nuts (A1) of the high-pressure
pipes at two of the atomisers.
Caution: Do not tighten the union nuts of the high-
pressure pipes more than the recommended torque
tension. If there is a leakage from the union nut,
ensure that the pipe is correctly aligned with the
atomiser inlet. Do not tighten the atomiser union nut
more, as this can cause a restriction at the end of
the pipe. This can affect the fuel delivery.
7. Put the electrical system switch to the “ON”
position. Operate the starter motor until fuel,
free from air, comes from the pipe connections.
Tighten the high-pressure pipe connections to 27
Nm (20 lbf ft) 2,8 kgf m. Return the switch to the
“OFF” position.
8. The engine is now ready to start.
9. If the engine runs correctly for a short time and
then stops or runs roughly, check for air in the
fuel system. If there is air in the fuel system,
there may be a leakage in the low pressure
system.
