Fuel Safety
DANGER
GASOLINE AND GASOLINE VAPORS ARE HIGHLY
FLAMMABLE AND EXPLOSIVE.
Fire or explosion can cause severe burns or death.
Gasoline and gasoline vapors:
–Gasoline is highly flammable and explosive.
–Gasoline can cause a fire or explosion if ignited.
–Gasoline is a liquid fuel but it’s vapors can ignite.
–Gasoline is a skin irritant and needs to be cleaned up
immediately if spilled on skin or clothes.
–Gasoline has a distinctive odor, this will help detect potential
leaks quickly.
–Gasoline expands or contracts with ambient temperatures.
Never fill the gasoline tank to full capacity, as gasoline needs
room to expand when temperatures rise.
–In the case of any petroleum gasoline fire, flames should never
be extinguished unless the fuel supply valve can be turned
OFF. By not doing so, if a fire is extinguished and the supply
of fuel is not turned OFF, an explosion hazard could be created.
When adding or removing gasoline:
DO NOT light or smoke cigarettes.
Always turn the generator off and let cool for a minimum of two
minutes before removing the gasoline cap. Afterwards, loosen
gasoline cap to relieve pressure from the gasoline tank.
Only fill or drain gasoline outdoors in a well-ventilated area.
DO NOT pump gasoline directly into the generator at the gas
station. Always use an approved fuel container to transfer the
gasoline to the generator.
DO NOT overfill the gasoline tank.
Always keep gasoline away from sparks, open flames, pilot lights,
heat and other sources of ignition.
When starting the generator:
DO NOT attempt to start a damaged generator.
Always make certain that the gasoline cap, air filter, spark plug,
fuel lines and exhaust system are properly secured, connected
and in place.
Always allow spilled gasoline to evaporate fully before attempting
to start the engine.
Make certain that the generator is resting firmly on level ground.
When operating the generator:
DO NOT move or tip the generator during operation.
DO NOT tip the generator or allow fuel or oil to spill.
When transporting or servicing the generator:
Make certain that the fuel valve is in the OFF position and the
gasoline tank is empty.
Disconnect the spark plug wire.
When storing the generator:
Store away from sparks, open flames, pilot lights, heat and other
sources of ignition.
Do not store generator or gasoline near furnaces, water heaters,
or any other appliances that produce heat or have automatic
ignitions.

Use clean, fresh, regular unleaded gasoline with a minimum
octane rating of 87 and an ethanol content of 10% or less by
volume. ybc
DO NOT mix oil with gasoline.
1. Remove the gasoline cap.
2. Slowly add gasoline to the tank. Tank is full when gasoline
reaches red circle on screen. DO NOT OVERFILL. Gasoline can
expand after filling. A minimum of ¼ in. (6.4 mm) of space left
in the tank is required for gasoline expansion, although more
than ¼ in. (6.4 mm) is recommended. Gasoline can be forced
out of the tank as a result of expansion if overfilled, and can
affect the stable running condition of the generator.
3. Screw on the gasoline cap and wipe away any spilled fuel.
CAUTION
Use unleaded gasoline with a minimum octane rating of 87
and an ethanol content of 10% or less by volume.
DO NOT light cigarettes or smoke when filling the tank.
DO NOT mix oil and gasoline.
DO NOT overfill the tank. Fill tank to approximately ¼ in. (6.4
mm) below the top of the tank to allow for gasoline expansion.
DO NOT pump gasoline directly into the generator at the pump.
Use an approved container to transfer the gasoline to the
generator.
DO NOT fill tank indoors.
DO NOT fill tank when the engine is running or hot.
WARNING
Pouring gasoline too fast through the fuel screen may result
in gasoline splashing over the generator and operator while
filling.
NOTICE
The generator engine works well with 10% or less ethanol
blend gasoline. When using ethanol-gasoline blends there are
some issues worth noting:
–Ethanol-gasoline blends can absorb more water than
gasoline alone.
–These blends can eventually separate, leaving water or
a watery goo in the tank, fuel valve and carburetor. The
compromised gasoline can be drawn into the carburetor
and cause damage to the engine and/or potential hazards.
–If a fuel stabilizer is used, confirm that it is formulated to
work with ethanol-gasoline blends.
–Any damages or hazards caused by using improper
gasoline, improperly stored gasoline, and/or improperly
formulated stabilizers, are not covered by manufacturer’s
warranty.
It is advisable to always shut off the gasoline supply and
run the engine to starvation after each use. See Storage
instructions for extended non-use.
Grounding
Your generator must be properly connected to an appropriate
ground to help prevent electric shock.
WARNING
Failure to properly ground the generator can result in electric
shock.
A ground terminal connected to the frame of the generator has
been provided (see Controls and Features for terminal location).
For remote grounding, connect of a length of heavy gauge
(12 AWG minimum) copper wire between the generator ground
terminal and a copper rod driven into the ground. We strongly
recommend that you consult with a qualified electrician to ensure
compliance with local electrical codes.
Neutral Floating*
–Neutral circuit IS NOT electrically connected to the frame/
ground of the generator.
–The generator (stator winding) is isolated from the frame and
from the AC receptacle ground pin.
–Electrical devices that require a grounded receptacle pin
connection will not function if the receptacle ground pin is not
functional.

Neutral Bonded to Frame*
–Neutral circuit IS electrically connected to the frame/ground of
the generator.
–The generator system ground connects lower frame cross-
member below the alternator. The system ground is connected
to the AC neutral wire.
* See your Specifications section for specified type of grounding.
OPERATION
Generator Location
NEVER operate the generator inside any building, including
garages, basements, crawlspaces and sheds, enclosure or
compartment, including the generator compartment of a
recreational vehicle. Please consult your local authority. In
some areas, generators must be registered with the local utility.
Generators used at construction sites may be subject to additional
rules and regulations. Generators should be on a flat, level surface
at all times. (Even while not in operation) Generators must have
at least 5 ft. (1.5 m) of clearance from all combustible material.
In addition to clearance from all combustible material, generators
must also have at least 3 ft. (91.4 cm) of clearance on all sides to
allow for adequate cooling, maintenance and servicing. Generators
should never be started or operated in the back of a SUV, camper,
trailer, in the bed of a truck (regular, flat or otherwise), under
staircases/stairwells, next to walls or buildings, or in any other
location that will not allow for adequate cooling of the generator
and/or the muffler. DO NOT contain generators during operation.
Allow generators to properly cool before transport or storage.
Place the generator in a well-ventilated area. DO NOT place the
generator near vents or intakes where exhaust fumes could be
drawn into occupied or confined spaces. Carefully consider wind
and air currents when positioning generator.
Failure to follow proper safety precautions may void
manufacturer’s warranty.
WARNING
Do not operate or store the generator in rain, snow, or wet
weather.
Using a generator or electrical appliance in wet conditions,
such as rain or snow, or near a pool or sprinkler system,
or when your hands are wet, could result in electrocution.
WARNING
During operation the muffler and exhaust fumes will become
hot. If adequate cooling and breathing space are not supplied,
or if the generator is blocked or enclosed, temperatures can
become extremely heated and may lead to fire.
Surge Protection
Electronic devices, including computers and many programmable
appliances use components that are designed to operate within a
narrow voltage range and may be affected by momentary voltage
fluctuations. While there is no way to prevent voltage fluctuations,
you can take steps to protect sensitive electronic equipment.
–Install UL1449, CSA-listed, plug-in surge suppressors on the
outlets feeding your sensitive equipment.
Surge suppressors come in single- or multi-outlet styles.
They’re designed to protect against virtually all short-duration
voltage fluctuations.
Starting the Engine
1. Make certain the generator is on a flat, level surface.
2. Disconnect all connected electrical loads from the generator.
Never start or stop the generator with electrical devices
plugged in or turned on.
3. Turn the gasoline fuel valve to the “ON” position.
4. Push the engine switch to the “ON” position.

5. Move the choke to the “CHOKE” position. Note: for restarting
a warm engine, move the choke to 75% of the CHOKE
position.
6. Pull the starter cord slowly until resistance is felt and then
pull rapidly.
7. As soon as engine starts, move the choke to the “RUN”
position over a 2-5 second duration.
8. Connect electrical loads.
NOTICE
Keep choke in “CHOKE” position for only 1 pull of the recoil
starter. After first pull, move choke to “RUN” position for up
to 3 pulls of the recoil starter. Too much choke leads to spark
plug fouling/engine flooding due to lack of incoming air. This
will cause the engine not to start.
NOTICE
For gasoline restarts with hot engine in hot ambient
temperature > 86°F (30°C), keep choke in 75% of the
“CHOKE” position for only 1 pull of the recoil starter. After
first pull, move choke to “RUN” position for up to 3 pulls of
the recoil starter. Too much choke leads to spark plug fouling/
engine flooding due to lack of incoming air. This will cause the
engine not to start.
NOTICE
For gas starting in cold ambient temperature < 59°F
(15°C), the choke must be in 100% of the “CHOKE” position
for recoil start procedures. Do not over-choke. As soon as
engine starts, gradually move the choke lever to the “RUN”
position over a 2-5 second duration.
NOTICE
If the engine starts but does not run make certain that the
generator is on a flat, level surface. The engine is equipped
with a low oil sensor that will prevent the engine from running
when the oil level falls below a critical threshold.
Connecting Electrical Loads
Let the engine stabilize and warm up for a few minutes after
starting.
Plug in and turn on the desired 120 or 240 (if applicable) Volt AC
single phase, 60 Hz electrical loads.
–DO NOT connect 3-phase loads to the generator.
–DO NOT overload the generator.

WARNING
Always remember to plug your appliances directly into the
generator and do not plug the generator power cord into any
electrical outlet or connect to the circuit breaker panel in your
home. Connecting a generator to your home’s electric utility
company’s power lines, or to another power source, called
‘backfeeding’ is a dangerous practice that is illegal in many
states and municipalities.
In addition, this action if done incorrectly, could damage your
generator, appliances and could cause serious injury or death
to you or a utility worker attempting to restore power during
an outage to the neighborhood who may then unexpectedly
encounter high voltage on the utility line and suffer a fatal
shock. Further, whether injuries occur or not, you may be
subject to fines or the utility company may disconnect your
home should this practice be found in your home.
If the generator will be connected to a building electrical
system, you are responsible for ensuring your generator’s
electricity does not backfeed into the electric utility power
lines. These connections must isolate the generator power
from the utility power and must comply with all applicable laws
and codes – Consult your local utility company or a qualified
electrician to properly install this connection.
Do Not Overload Generator
Capacity
Follow these simple steps to calculate the running and starting
watts necessary for your purposes:
1. Select the electrical devices you plan on running at the same
time.
2. Total the running watts of these items. This is the amount of
power you need to keep your items running.
3. Identify the highest starting wattage of all devices identified
in step 1. Add this number to the number calculated in step 2.
Starting wattage is the surge of power needed to start some
electric driven equipment. Following the steps listed under
“Power Management” will guarantee that only one device will
be starting at a time.
Power Management
Use the following formula to convert voltage and amperage to
watts:
Volts ×Amps = Watts
To prolong the life of your generator and attached devices, follow
these steps to add electrical load:
1. Start the generator with no electrical load attached.
2. Allow the engine to run for several minutes to get up to
temperature.
3. Plug in and turn on the first item. It is best to attach the item
with the largest load first.
4. Allow the engine to stabilize.
5. Plug in and turn on the next item.
6. Allow the engine to stabilize.
7. Repeat steps 5-6 for each additional item.
NOTICE
Never exceed the specified capacity when adding loads to the
generator.
Stopping the Engine
1. Turn off and unplug all connected electrical loads. Never start
or stop the generator with electrical devices plugged in or
turned on.
2. Let the generator run at no-load for several minutes to
stabilize internal temperatures of the engine and generator.
3. Press the engine switch to the “OFF” position.
4. Turn the fuel valve to the “OFF” position.
Important: Always ensure that the fuel valve and the engine
switch are in the “OFF” position when the generator is not in use.
