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 autho-
rized service center restore high altitude modied engines to the original factory specication before operating
below 2000 feet.
