Caution: Use a spanner to prevent movement of the fuelled starting aid (C1) when the union nut (C2) is
loosened or tightened.
3 Loosen the union nut (C2) at the fuelled starting aid and operate the priming lever of the fuel lift pump (D1)
until fuel, free of air, comes from the connection. Tighten the union nut at the starting aid.
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.

4 Loosen the high-pressure connections at two of the atomisers (E1).
Caution: Damage to the fuel injection pump, battery and starter motor can occur if the starter motor is used
excessively to eliminate air from the fuel system.

5 Put the electrical system switch to the "ON" position. Ensure that the manual stop control, if one is fitted, is
in the "RUN" position. Operate the starter motor until fuel, free from air, comes from the high-pressure pipe
connections. Tighten the high-pressure pipe connections to 22 Nm (16 lbf ft) 2,2 kgf m. Return the switch to
the "OFF" position.
6 The engine is now ready to start.
Caution: Operate the engine at low idle speed for a minimum of five minutes immediately after air has been
removed from the fuel system. This will ensure that the pump is free of air and prevent any damage to the
pumps internal parts by metal to metal contact.
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.
