if it is to be run continuously above 5,000 feet (1,500 meters). Failure to do so,
may result in poor engine performance, spark plug fouling, hard starting, and
increased emissions.
■ Carburetor modification by an authorized SUBARU Industrial Power Products
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 5,000 feet or lower.
In doing so, the engine will overheat and cause serious engine damage.
Please have an authorized SUBARU Industrial Power Products dealer restore
high altitude modified engines to the original factory specification before operating below 5,000 feet.
