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
falls 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 (P. 8).
