• Turn engine RUN/STOP switch to
• Pull engine CHOKE knob outward to
(Figure 12).
• To start engine, firmly grasp the recoil handle and pull slowly until
increased resistance is felt. Pull rapidly up and away.

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
• 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 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
