Fuel Safety
!DANGER
GASOLINE, GASOLINE VAPORS AND PROPANE (LPG) 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.
–In any petroleum gas fire, flames should not be extinguished
unless by doing so the fuel supply valve can be turned OFF.
This is because if a fire is extinguished and a supply of
fuel is not turned OFF, then an explosion hazard could be
created.
–Gasoline expands or contracts with ambient temperatures.
Never fill the gasoline tank to full capacity, as gasoline
needs room to expand if temperatures rise.
LPG:
–LPG is highly flammable and explosive.
–LPG is under pressure and can cause a fire or explosion if
ignited.
–LPG is heavier than air and can settle in low places while
dissipating.
–LPG has a distinctive odor added to help detect potential
leaks quickly.
–In any petroleum gas fire, flames should not be extinguished
unless the fuel supply valve is turned OFF. This is because if
a fire is extinguished and a supply of fuel is not turned OFF,
then an explosion hazard could be created.
–When exchanging LPG cylinders, be sure the cylinder valve
is of the same type.
–Always keep the LPG cylinder in an upright position.
–LPG will burn skin if it comes in contact with it. Keep any
and all LPG away from skin at all times.
When adding or removing gasoline:
Turn the generator off and let it cool for at least two minutes
before removing the gasoline cap. Loosen the cap slowly to
relieve pressure in the tank.
Only fill or drain gasoline outdoors in a well-ventilated area.
DO NOT pump gasoline directly into the generator at the gas
station. Use an approved container to transfer the fuel 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.
DO NOT light or smoke cigarettes.
When starting the generator:
DO NOT attempt to start a damaged generator.
Make certain that the gasoline cap, air filter, spark plug, fuel
lines and exhaust system are properly in place.
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, the
gasoline tank is empty.
For LPG compatible models, be sure that the LPG cylinder is
disconnected and stored securely away from the generator.
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, gasoline or LPG cylinders near furnaces,

"NOTICE
The first 5 hours of run time are the break-in period for the
unit. During the break in period stay at or below 50% of the
running watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the load will also
cause engine speed to vary and help seat piston rings. After
the 5 hour break-in period, change the oil.
"NOTICE
Weather will affect engine oil and engine performance.
Change the type of engine oil used based on weather
conditions to suit the engine needs.
"NOTICE
Synthetic oil may be used after the 5 hour initial break-
in period. Using synthetic oil does not increase the
recommended oil change interval. Full synthetic 5W-30 oil
will aid in starting in cold ambient <5º C (41º F).
Add Fuel
1. Use clean, fresh, regular unleaded gasoline with a
minimum octane rating of 85 and an ethanol content of
10% or less by volume. ybc
2. DO NOT mix oil with gasoline.
3. Remove the gasoline cap.
4. 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 ¼in. (6.4 mm) of
space left in the tank is required for gasoline expansion,
although more than ¼in. (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.
5. Screw on the gasoline cap and wipe away any spilled fuel.
!CAUTION
Use regular unleaded gasoline with a minimum octane
rating of 85 and an ethanol content of 10% or less by
volume.
DO NOT mix oil and gasoline.
Fill tank to approximately ¼in. (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.
DO NOT overfill the tank.
DO NOT light cigarettes or smoke when filling the tank.
!WARNING
Pouring gasoline too fast through the fuel screen may result
in blow back of gasoline at the operator while filling.
"NOTICE
Our engines work 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.
–With gravity-fed supplies, the compromised gasoline can
be drawn into the carburetor and cause damage to the
engine and/or potential hazards.
–There are only a few suppliers of fuel stabilizer that are
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, run the
engine to starvation and drain the tank when the equipment
is not in use for more than 30 days.

100455 - 2000W PORTABLE INVERTER GENERATOR OPERATION

ensure compliance with local electrical codes.
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.
Install battery-operated carbon monoxide alarms or plug-in
carbon monoxide alarms with battery back-up in your home
according to the manufacturer’s instructions.
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 produced
will become hot. If adequate cooling and breathing space
are not supplied, or if the generator is blocked or contained,
temperatures can become extremely heated and may lead
to fire.
Grounding
A ground terminal connected to the frame of the generator has
been provided (see Controls and Features for terminal location).
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 model's control panel for specified type of grounding.
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

> 30°C (86°F): Keep the choke in 75% of the “CHOKE”
position for only 1 pull of the recoil starter. After first pull,
push choke to the “RUN” position for up to 3 more pulls
of the recoil starter. Too much choke leads to spark plug
fouling/engine flooding due to the lack of incoming air. This
will cause the engine not to start.
"NOTICE
For gas starting in cold ambient <15°C (59°F): The
choke must be in 100% of the “CHOKE” position for recoil
start procedures. Do not over-choke. As soon as engine
starts, push the choke knob in the “RUN” position.
"NOTICE
If the engine starts but does not continue to 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.

single phase, 60 Hz electrical loads.
–DO NOT connect 3-phase loads to the generator.
–DO NOT connect 50 Hz loads to the generator.
–DO NOT overload the generator.
!WARNING
Connecting a generator to your electric utility company’s
power lines or to another power source may be against
the law. In addition this action, if done incorrectly, could
damage your generator and appliances and could cause
serious injury or even death to you or a utility worker who
may be working on nearby power lines. If you plan to run a
portable electric generator during an outage, please notify
your electric utility company immediately and remember to
plug your appliances directly into the generator. Do not plug
the generator into any electric outlet in your home. Doing
so could create a connection to the utility company power
lines. You are responsible for ensuring that your generator’s
electricity does not feed back into the electric utility power
lines.
If the generator will be connected to a building electrical
system, consult your local utility company or a qualified
electrician. Connections must isolate generator power from
utility power and must comply with all applicable laws and
codes.
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 extra burst
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 stabilize.
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.
Eco Mode
The Eco Mode switch can be activated to turn on economy
control in order to minimize fuel consumption and noise while
operating the unit during times of reduced electrical output. Eco
Mode allows the engine speed to idle during periods of non-use.
The engine speed returns to normal when an electrical load is
connected. When the economy switch is off, the engine runs at
normal speed continuously.
!CAUTION
For periods of high electrical load or momentary
fluctuations, the Eco Mode should be off.
