A wrench shall be put on the nut head of fuelled starting aid device to prevent the movement during
tightening or loosing the union nut.
6. If the fuel pipe on the fuelled starting aid has been emptied, loosen the union nut (A1) at the fuelled starting aid
(if one is fitted) and operate the lift pump until fuel, free from air, comes from the connection. Tighten the union
nut at the starting aid. A wrench shall be put on the nut head of fuelled starting aid device to prevent the
movement during tightening or loosing the union nut.
Attention:
Do not tighten the 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. Loosen the union nuts of the high-pressure pipes (B1) at two of the atomisers. If a manual stop control equipped,
ensure that it is in the "run" position. Operate the starter motor until fuel, free from air, comes from the pipe
connections. Tighten the high-pressure pipe connections up to 22N, 22Kg.f.m.
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 is probably a leakage in the low pressure system.
