Operating in Warm Temperature Climates
Ingersoll Rand branded engines are designed to operate using glycol base engine coolants.
Always use a recommended glycol base engine coolant, even when operating in geographical
areas where freeze protection is not required.
IMPORTANT: Water may be used as coolant in emergency situations only.
Foaming, hot surface aluminum and iron corrosion, scaling, and cavitation will occur
when water is used as the coolant, even when coolant conditioners are added.
Drain cooling system and refill with recommended glycol base engine coolant as soon
as possible.
Engine Break-In Service
The engine is ready for normal operation. However, extra care during the first 100 hours of
operation will result in more satisfactory long-term engine performance and life. DO NOT
exceed 100 hours of operation with break-in oil.
