Normal Starting Procedure QSB4.5 and QSB6.7
Page 1-6 Section 1 - Operating Instructions
After starting a cold engine, increase the engine speed
(rpm) slowly to provide adequate lubrication to the
bearings and to allow the oil pressure to stabilize.
CAUTION
Do not operate engine at low idle for long periods
with engine coolant temperature below the minimum
specification in Maintenance Specifications (Section
V). This can result in the following:
• Fuel Dilution of the lubricating oil
• Carbon build up in the cylinder
• Cylinder head valve sticking
• Reduced performance.
