Operating Instructions for Starting the Engine
Checking the Axial Power Turbine
Check the axial power turbine for excessive noise or vibration. Stop the engine
immediately if unusual noise or vibration is noted. Do not restart the engine until
the cause of the concern has been investigated and corrected.
Avoid Unnecessary Idling
Whenever possible, unnecessary idling should be avoided. During long engine
idling periods with the transmission in neutral, the engine coolant temperature may
fall below the normal operating range. The incomplete combustion of fuel in a cold
engine will cause crankcase oil dilution, formation of lacquer or gummy deposits
on the valves, pistons, and rings, and rapid accumulation of sludge in the engine.
When prolonged idling is necessary, maintain at least 900 rpm.
Stopping the Engine
Stop an engine under normal operating conditions as follows:
NOTICE: Do not stop a turbocharged engine immediately after a high-
speed operation. Allow a sufficient cool-down period of about five minutes
to prevent the turbocharger from continuing to turn without an oil supply to
the bearings or damage can result.
1. Reduce engine speed to idle and put all shift levers in the neutral position.
NOTE: Cool-down idling needs to take place after pulling off an interstate.
When finding a parking spot or backing into a dock, immediate shutdown
should be avoided. Shutting the engine off immediately retains more block
heat than if the engine runs at idle for five minutes.
2. Allow the engine to run between idle and 1000 rpm with no load for five
minutes. This allows the engine to cool and permits the turbocharger to slow
down. After five minutes, shut down the engine.
Emergency Jump Starting
The engine's electronic system operates on 12 volts DC. If a DD Platform engine
with an electric starting motor requires emergency jump starting, DO NOT
EXCEED 16 VOLTS DC.
WARNING: BATTERY EXPLOSION
To avoid injury from battery explosion when jump starting the
engine, do not attach the cable end to the negative terminal of the
disabled battery.
