How to prime the lubrication system
Caution: Before starting the engine for the first time, or after it has stood idle for more than three months, the
engine lubrication system must be primed.
To achieve this the engine is cranked over on the starter motors using the following procedure.
Note: To prevent the engine running during this operation disconnect the power lead to the actuator. Refer to
(A1) for Heinzmann actuators and (A2) for Woodward actuators.
1 Manually set the air shutoff valves (B1) to the run position (B2).
2 Crank the engine over until 0,3 bar (5 lb/in
2
) shows on the oil pressure gauge.
3 Continue cranking for ten more seconds to ensure that oil is circulating through the turbochargers.
4 Reconnect the actuator power leads.
