IMPORTANT: It is important to prevent gum deposits from forming
in fuel system parts such as the carburetor, fuel hose or tank
during storage. Alcohol-blended fuels (called gasohol, ethanol
or methanol) can attract moisture, which leads to separation and
formation of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of 30 days or
longer. See the "Storage" section. Never use engine or carburetor
cleaner products in the fuel tank as permanent damage may occur.
2.8 TO START THE ENGINE
Never start or stop engine with electrical

devices plugged into the receptacles AND
devices turned on.
• Unplug all electrical loads from the unit's receptacles before
starting the engine.
• Make sure the unit is in a level position.
• Open the fuel shut-off valve (Figure 11).
Figure 11 - Fuel Shut-off Valve
• Pull engine CHOKE knob outward to "Full Choke" position
(Figure 12).
Figure 12 - Choke Position
Choke
• To start engine, press and hold the Start/Run/Stop switch in
the "Start" position. The engine will crank and attempt to start.
When the engine starts, release the switch to the run position.
• When the engine starts, push choke knob to "1/2 Choke"
position until the engine runs smoothly and then fully in to the
"Run" position. If engine falters, pull choke knob back out to
"1/2 Choke" position until the engine runs smoothly and then
to "Run" position.
• This generator is also equipped with a manual recoil starter
which may be used if the battery is discharged.
The switch must be in the RUN position.
• To start manually, firmly grasp the recoil handle and pull slowly
until increased resistance is felt. Pull rapidly up and away to
start engine. Then follow the same choke sequence listed
above.
If engine fires, but does not continue to run, pull choke knob to
"Full Choke" and repeat starting instructions.
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 Start/Run/Stop switch to "Off" position.
• Close fuel valve.
2.10 LOW OIL PRESSURE SHUTDOWN SYSTEM
The engine is equipped with a low oil pressure sensor that shuts
down the engine automatically when the oil pressure drops below
5 psi. If the engine shuts down by itself and the fuel tank has
enough gasoline, check engine oil level.
2.10.1 INITIAL START-UP
A delay built into the low oil shutdown system allows oil pressure
to build during starting. The delay allows the engine to run for
about 10 seconds before sensing oil pressure.
2.10.2 SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the engine
shuts down.
