Toro 51944 - Emissions Maintenance Schedule; High Altitude Engine Operation

18
High Altitude Engine Operation:
Please have an authorized service center modify this engine if it is to be run above 2000 feet. Failure to do so may result in
poor engine performance, spark plug fouling, hard starting, and increased emissions. Carburetor modication by an autho-
rized service center will improve performance and allow that this engine meet the EPA (Environmental Protection Agency)
and California ARB (Air Resources Board) emission standards.
An engine modied for high altitudes can not be run below 2000 feet. The engine will overheat and result in serious engine
damage. Please have an authorized service center restore high altitude modied engines to the original factory specication
before operating below 2000 feet.
