Gasoline and Gasoline Vapors (Gas):
– GAS IS HIGHLY FLAMMABLE AND EXPLOSIVE.
– Gas can cause a fire or explosion if ignited.
– Gas is a liquid fuel but it’s vapors can ignite.
– Gas is a skin irritant and needs to be cleaned up
immediately if spilled on skin or clothes.
– Gas has a distinctive odor, this will help detect
potential leaks quickly.
– In any 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.
– Gas expands or contracts with ambient temperatures.
Never fill the gas tank to full capacity, as gas needs
room to expand if temperatures rise.
Liquefied Petroleum Gas (LPG):
– LPG IS HIGHLY FLAMMABLE AND EXPLOSIVE.
– Flammable gas under pressure 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 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.
– 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.

11 REV 71531-20140424
ENGLISH 71531
ASSEMBLY
Add Fuel (Gas) Cont’d.
Our engines work well with 10% or less ethanol
blend fuels. When using blended fuels 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 fuel supplies, this compromised
fuel 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 blend
fuels.
– Any damages or hazards caused by using
improper fuel, improperly stored fuel, and/
or improperly formulated stabilizers, are not
covered by manufacture’s warranty.
It is advisable to always shut off the fuel supply,
run the engine to fuel starvation and drain the tank
when the equipment is not in use for more than 30
days.
NOTE
Add Fuel (Gas)
1. Use clean, fresh, regular unleaded fuel with a
minimum octane rating of 85 and an ethanol content
of less than 10% by volume.
2. DO NOT mix oil with fuel.
3. Clean the area around the fuel cap.
4. Remove the fuel cap.
5. Slowly add fuel to the tank. DO NOT OVERFILL.
Fuel can expand after filling. A minimum of
¼ in. (6.4 mm) of space left in the tank is required
for fuel expansion, more than ¼ in. (6.4 mm) is
recommended. Fuel can be forced out of the tank as
a result of expansion if it is overfilled, and can affect
the stable running condition of the product. When
filling the tank, it is recommended to leave enough
space for the fuel to expand.
6. Screw on the fuel cap and wipe away any spilled fuel.
Use regular unleaded gasoline with a minimum
octane rating of 85.
Do not mix oil and gasoline.
Fill tank to approximately ¼ in. (6.4 mm) below the
top of the tank to allow for fuel expansion.
DO NOT pump gas directly into the generator at the
gas station. Use an approved container to transfer
the fuel to the generator.
DO NOT fill fuel tank indoors.
DO NOT fill fuel tank when the engine is running or hot.
DO NOT overfill the fuel tank.
DO NOT light cigarettes or smoke when filling the
fuel tank.
CAUTION
Pouring fuel too fast through the fuel screen may
result in blow back of fuel at the operator while filling.
WARNING

REV 71531-20140424 12
71531 ENGLISH
ASSEMBLY
Do not allow children to tamper or play with the
cylinder or hose connections.
CAUTION
Use approved LPG cylinders equipped with an
OPD (overfilling prevention device) valve. Always
keep the cylinder in a vertical position with the
valve on top and installed at ground level on a flat
surface Cylinders must not be installed near any
heat source and should not be exposed to sun, rain,
and dust. When transporting and storing, turn off
the cylinder valve and fuel valve, and disconnect
the cylinder. Plug the outlet, usually by a plastic
protective cap, if one is available. Keep cylinders
away from heat and ventilated when in a vehicle.
CAUTION
Connecting LPG Cylinder Cont’d.
Grounding
Your generator must be properly connected to an
appropriate ground to help prevent electric shock.
A ground terminal connected to the frame of the generator
has been provided on the power panel. 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.
Failure to properly ground the generator can result
in electric shock.
WARNING
– Use only standard 20 or 30 pound capacity LP
tanks with Type 1, right hand Acme threads.
– Verify the requalification date on the tank has
not expired.
– All new cylinders must be purged of air and
moisture prior to filling. Used cylinders that have
not been plugged or kept closed must also be
purged.
– The purging process should be done by a LPG
supplier. (Cylinders from an exchange supplier
should have been purged and filled properly
already).
– Always position the cylinder so the connection
between the valve and the gas inlet won’t cause
sharp bends or kinks in the hose.
NOTE
Connecting Liquid Petroleum Gas (LPG) Cylinder
1. Make sure the fuel valve on the generator is in the off
position.
2. Attach the LPG hose (included) to the LPG hose
connector on the side of the generator and tighten
with a 19 mm or adjustable wrench.
Important: DO NOT use tape or any other type of
sealant to seal LPG hose connection.
3. Remove the safety plug or cap from the cylinder
valve.
4. Attach the other end of the hose to the LPG
connector on the cylinder and hand tighten.
5. Check all connections for leaks by wetting the fittings
with a solution of soap and water. Bubbles which
appear or bubbles which grow indicate that a leak
exists. If a leak exists at a fitting then turn off the
gas valve at the tank and tighten the fitting. Turn the
gas back on and recheck the fitting with the soap
and water solution. If the leak continues or if the leak
is not at a fitting then do not use the generator and
contact customer service.
If there is a strong smell of gas: Close off the gas
supply at the cylinder. Use soapy water, which will
produce a large bubble at the point of any leak, to
check the hose, and connections on the cylinder valve
and the generator. Do not smoke or light a cigarette,
or check for leaks using a match, open flame source
or lighter. Contact a qualified technician to inspect
and repair the LPG system if a leak is found, before
using the generator.

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.
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
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.
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.
1. 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.
Voltage fluctuation may impair the proper
functioning of sensitive electronic equipment.
CAUTION
Grounding
The generator system ground connects the frame to the
ground terminals on the power panel.
– 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.

fuel has been selected and the valve is in the “ON”
position. Only when the fuel valves are in the “OFF”
position can the cover slide side to side.
NOTE
The fuel selector is locked into place once a
“CLICK” sound is made. Only then can a fuel valve
be turned to the vertical position.
NOTE
Fuel Selector Switch
The fuel selector switch on the front panel of the
generator is designed specifically to choose between the
fuel source desired, Gas or LPG.
To select a fuel source simply slide the switch cover to
either the right or left, and this will uncover the fuel
valve of the fuel selected.
The LPG fuel valve (A) is to the left of the switch cover.
The gas fuel valve (B) is to the right of the switch cover.

1. Make certain the generator is on a flat, level surface.
2. Disconnect all electrical loads from the generator.
Never start or stop the generator with electrical
devices plugged in or turned on.
3. Turn the gas fuel valve to the “ON” position.
4. Move the choke lever to the “CHOKE” position.
5. Flip the ignition switch to the “ON” position.
6. Turn the battery switch to the “ON” position.
7. ELECTRIC START: Press and hold the ignition switch
to the “START” position. Release as the engine
begins to roll over. If the engine fails to start within
five seconds, release the switch and wait at least ten
seconds before attempting to start the engine again.
8. RECOIL START: Pull the starter cord slowly until
resistance is felt and then pull rapidly.
9. Do not over-choke. As soon as engine starts, move the
choke lever to the “RUN” position.
LPG
1. Make certain the generator is on a flat, level surface.
2. Disconnect all electrical loads from the generator.
Never start or stop the generator with electrical
devices plugged in or turned on.
3. Fully open the LPG cylinder fuel knob.
4. Turn the LPG fuel valve to the “ON” position.
5. Move the choke lever to the “RUN” position.
6. Flip the ignition switch to the “ON” position.
7. Turn the battery switch to the “ON” position.
8. ELECTRIC START: Press and hold the ignition switch
to the “START” position. Release as the engine
begins to roll over. If the engine fails to start within
five seconds, release the switch and wait at least ten
seconds before attempting to start the engine again.
9. RECOIL START: Pull the starter cord slowly three
or four times until resistance is felt. Next pull the
starter cord slowly until resistance is felt and then pull
rapidly.
Keep choke lever in “Choke” position for only 1
pull of the recoil starter. After first pull, move choke
lever to the “Run” position for up to the next 3
pulls of the recoil starter. Too much choke leads to
sparkplug fouling/engine flooding due to the lack of
incoming air. This will cause the engine not to start.

OPERATION
Connecting Electrical Loads
1. Let the engine stabilize and warm up for a few
minutes after starting
2. Plug in and turn on the desired 120/240 Volt AC
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.
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.
NOTE
Stopping the Engine
1. Turn off and unplug all 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. Turn the Fuel Valve to the “OFF” position.
4. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.
5. Press the engine switch to the “OFF” position.
6. Turn Battery Switch to the “Off” Position.
Important: Always ensure that the Fuel Valve and the
Engine Switch are in the “OFF” position when the
engine is not in use.
When turning off the generator after LPG operation, turn
the fuel knob on LPG cylinder off too. Make sure it is in
the fully closed position.
NOTE
If the engine will not be used for a period of two (2) weeks
or longer, please see the Storage section for proper engine
and fuel storage.
NOTE
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. Surge 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.
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.
NOTE
When the battery switch is in the “ON” position, the
switch will light up if the battery is sending out a
charge. If the switch does not light up while in the “ON”
position, check that the battery connection is still good.
NOTE
The supplied 12V 15AH battery does re-charge while the
engine is running, but it is also recommended that the
battery be fully charged at least once per month.
NOTE
Starting the Engine Cont’d.
If the ignition switch is held down in the “Start” position
longer than 5 seconds it could damage the starter.

OPERATION
Never exceed the specified capacity when adding
loads to the generator.
NOTE
Operation using the alternative main jet at
elevations lower than the recommended minimum
altitude can damage the engine. For operation at
lower elevations, the standard main jet must be
used. Operating the engine with the wrong engine
configuration at a given altitude may increase
its emissions and decrease fuel efficiency and
performance.

NOTE
Observing frost on LPG containers and regulators
is common during operation and normally is not
an indication of a problem. As LPG vaporizes and
travels from the tank to the generator engine it
expands. The amount of frost that forms can be
affected by the size of the container, the amount of
fuel being used, the humidity of the air and other
operating conditions. In unusual situations this
frost may eventually restrict the flow of gas to the
generator resulting in deteriorating performance.
For example, if the tank temperature is reduced
to a very low level then the rate at which the LPG
vaporizes is also reduced and may not provide
sufficient fuel flow to the engine. This is not an
indication of a problem with the generator but
only a problem with the flow of gas from the LPG
container. If generator performance seems to be
deteriorating at the same time that ice formation is
observed on tank valve, hose or regulator then some
actions may be taken to eliminate this symptom.
In these rare situations it can be helpful to reduce
or eliminate the cold fuel system effects by doing
one of the following:
– Exchanging fuel tanks to allow the first tank to
warm up, repeating as necessary
– Placing the LPG container at the end of the
generator near the handle, where engine fan air
flows out from the generator. This air is slightly
heated by flowing over the engine. The container
should not be placed in the path of the muffler
outlet.
– The container can be temporarily warmed by
pouring warm water over the top of the tank.
Operation at High Altitude
The density of air at high altitude is lower than at sea
level. Engine power is reduced as the air mass and air-
fuel ratio decrease. Engine power and generator output
will be reduced approximately 3½% for every 1000
feet of elevation above sea level. This is a natural trend
and cannot be changed by adjusting the engine. At high
altitudes increased exhaust emissions can also result
due to the increased enrichment of the air fuel ratio.
Other high altitude issues can include hard starting,
increased fuel consumption and spark plug fouling.
To alleviate high altitude issues other than the natural
power loss, Champion Power Equipment can provide a
high altitude carburetor main jet. The alternative main
jet and installation instructions can be obtained by
contacting Customer Support. Installation instructions
are also available in the Technical Bulletin area of the
Champion Power Equipment internet site.
The part number and recommended minimum altitude
for the application of the high altitude carburetor main
jet is listed in the table below.
In order to select the correct high altitude main jet
it is necessary to identify the carburetor model. For
this purpose, a code is stamped on the side of the
carburetor. Select the correct main jet part number
corresponding to the carburetor code found on your
particular carburetor.
Power Management
Use the following formula to convert voltage and
amperage to watts:
Volts x 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.
