Oil Alert System
The Oil Alert system is designed to prevent engine damage caused by an in-
sufficient amount of oil in the crankcase. Before the oil level in the
crankcase can fall below a safe limit, the Oil Alert system will automatically
shut down the engine (the engine switch will remain in the ON position).
If the Oil Alert system shuts down the engine, the Oil Alert lamp will flash
when you .operate the starter, and the engine will not run. If this occurs,
add engine oil (page 7).

At high altitude, the standard carburetor air-fuel mixture will be excessively
rich. Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller diameter
main fuel jet in the carburetor and readjusting the pilot screw. If you always
operate the water pump at altitudes higher than 6,000 feet above sea
level, have your authorized Honda Water Pump dealer perform these car-
buretor modifications.
Even with suitable carburetor jetting, engine horsepower will decrease ap-
proximately 3.5% for each 1,000 foot increase in altitude. The affect of
altitude on horse’power will be greater than this if no carburetor modifica-
tion is made.
CAUTION: Operation of the Water Pump at an altitude lower than the car-
buretor is jetted for may result in reduced performance, overheating, and
serious engine damage caused by an excessively lean air/fuel mixture.
