IMPORTANT: Do not overload the generator. Also, do not overload
individual panel receptacles. These outlets are protected against
overload with push-to-reset-type circuit breakers. If amperage rating
of any circuit breaker is exceeded, that breaker opens and electrical
output to that receptacle is lost. Read “Don’t Overload the Generator”
carefully.
2.8 STOPPING THE ENGINE
1. Shut off all loads, then unplug the electrical loads from generator
panel receptacles. Never start or stop the engine with electrical
devices plugged in and turned on.
2. Let engine run at no-load for several minutes to stabilize the
internal temperatures of engine and generator.
3. Move ON/OFF switch to OFF position.
4. Close fuel valve.
2.9 LOW OIL LEVEL SHUTDOWN SYSTEM
The engine is equipped with a low oil level sensor that shuts down
the engine automatically when the oil level drops below a specified
level. If the engine shuts down by itself and the fuel tank has enough
gasoline, check engine oil level.
2.9.1 SENSING LOW OIL LEVEL
If the system senses a low oil level during operation, the engine shuts
down. The engine will not run until the oil has been refilled to the
proper level.
3.1 MAINTENANCE SCHEDULE
Follow the calendar intervals. More frequent service is required when
operating in adverse conditions noted below.
