RECOMMENDED OIL
Use 4-stroke motor oil that meets or exceeds the requirements for API
service classification SE or later (or equivalent). Always check the API
service label on the oil container to be sure it includes the letters SE or
later (or equivalent).
AMBIENT TEMPERATURE
SAE 10W-30 is recommended for general use. Other viscosities shown
in the chart may be used when the average temperature in your area is
within the indicated range.
Oil Alert System (Where equipped)
The Oil Alert System is designed to prevent engine damage caused by
an insufficient amount of oil in the crankcase. Before the oil level in the
crankcase can fall below a safe limit, the Oil Alert System will auto-
matically stop the engine (the engine switch will remain in the ON
position).
If the engine stops and will not restart, check the engine oil level
before troubleshooting in other areas.
Running the engine with insufficient oil can cause serious engine
damage.
