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.
Check Oil Level
Change Oil +
Check Valve Clearance
Service Air Filter
Replace Spark Plug
+ Change oil after first 20 hours of operation, then every season.

3.3 GENERAL RECOMMENDATIONS

The warranty of the generator does not cover items that have been
subjected to operator abuse or negligence. To receive full value from
the warranty, the operator must maintain the generator as instructed
in this manual.
Some adjustments will need to be made periodically to properly
maintain the generator.
All adjustments in the Maintenance section of this manual should
be made at least once each season. Follow the requirements in the
"Maintenance Schedule".
Once a year replace the spark plug and replace the air filter. A
new spark plug and clean air filter assure proper fuel-air mixture
and help the engine run better and last longer.

3.3.1 GENERATOR MAINTENANCE

Generator maintenance consists of keeping the unit clean and dry.
At Each Use
Operate and store the unit in a clean dry environment where it will not

leaves, or any other foreign material.
Every Season
Change oil every month when operating under heavy load or in high temperatures.
