2.9 STARTING ELECTRIC START ENGINES

Never start or stop engine with electrical
devices plugged into the receptacles AND
devices turned on.
1. Unplug all electrical loads from the unit's receptacles before
starting the engine.
2. Make sure the unit is in a level position (not to exceed 15° in
any direction).
3. Open the fuel shut-off valve (Figures 10).
4. Move engine CHOKE knob outward to FULL CHOKE position
(Figure 12).
5. 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.
6. When the engine starts, move choke knob to “1/2 Choke”
position until the engine runs smoothly and then fully in to the
“Run” position. If engine falters, move choke knob back out to
“1/2 Choke” position until the engine runs smoothly and then
to “Run” position.
2.9.1 MANUAL START
This generator is also equipped with a manual recoil starter which
may be used if the battery is discharged.
NOTE:
The switch must be in the RUN position. Use one of the
generator’s receptacle outlets along with the included battery
charger to charge the battery while the generator is running.
• 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.
NOTE:
If engine fires, but does not continue to run, move choke lever
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.
2.10 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 Run/Stop switch to OFF position.
4. Close fuel valve.
2.11 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.
2.11.1 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.
2.12 CHARGING THE BATTERY (ELECTRIC START
UNITS ONLY)

Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion.
Such an explosion can shatter the battery and
cause blindness or other serious injury.
Do not permit smoking, open flame, sparks
or any other source of heat around a battery.
Wear protective goggles, rubber apron and
rubber gloves when working around a battery.
Battery electrolyte fluid is an extremely
corrosive sulfuric acid solution that can cause
severe burns. If spill occurs flush area with
clear water immediately.
NOTE:
The battery shipped with the generator has been fully charged.
A battery may lose some of its charge when not in use for
prolonged periods of time. If the battery is unable to crank the
engine, plug in the 12V charger included in the accessory box.
RUNNING THE GENERATOR DOES NOT CHARGE THE BATTERY.
