Maintenance

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.

2.9 STOPPING THE ENGINE

• 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.
• Let engine run at no-load for several minutes to stabilize the
internal temperatures of engine and generator.
• Move Run/Stop switch to OFF position.
• Close fuel valve.

2.10 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.

2.10.1 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 30 hours of operation then every season.
* Change oil and oil filter every month when operating under heavy load or in high
temperatures.
** Clean more often under dirty or dusty operating conditions. Replace air filter
parts if they cannot be adequately cleaned.
*** Check valve clearance and adjust if necessary after first 50 hours of
operation and every 100 hours thereafter.

3.2.3 EMISSIONS INFORMATION

The Environmental Protection Agency (EPA) requires that this
generator comply with exhaust emission standards. The engine
used in this generator is certified to meet the applicable EPA
emission levels. It is important to follow the maintenance
specifications provided in this manuals to ensure that the engine
complies with the applicable emission standards for the duration
of the engine's life. The emission control system on this generator
consists of the following:
• Air Induction system
~ Intake Pipe/Manifold
~ Air Cleaner
• Exhaust System
~ Exhaust manifold
~ Muffler
The Emissions Compliance Period referred to on the Emissions
Compliance Label indicates the number of operating hours
for which the engine has been shown to meet EPA emission
requirements.
• Ignition System
~ Spark Plug
~ Ignition Coil
• Fuel System
