High Altitude Engine Operation - Yamaha EH64 Manual Del Propietário

HIGH ALTITUDE ENGINE OPERATION

■ Please have an authorized YAMAHA dealer modify this engine if it is to be run
continuously above 5000 feet (1500 meters).
Failure to do so, may result in poor engine performance, spark plug fouling, hard
starting, and increased emissions.
■ Carburetor modification by an authorized YAMAHA dealer will improve performance
and allow that this engine meets EPA (Environmental Protection Agency) and
California ARB (Air Resources Board) emission standards throughout its useful life.
■ An engine converted for high altitudes can not be run at 5000 feet or lower.
In doing so, the engine will overheat and cause serious engine damage.
Please have an authorized YAMAHA dealer restore high altitude modified engines to
the original factory specification before operating below 5000 feet.
