High Altitude Engine Operation
Please have an authorized service center adjust this engine if it is to be run above 2000 feet. Failure to do so may result in
poor engine performance and increased emissions. An engine adjusted for high altitudes can not be run at 2000 feet or lower.
In doing so, the engine will overheat and cause serious engine damage. Please have an authorized service center restore high
altitude modified engines to the original factory specification before operating below 2000 feet.
