ASSEMBLY
This unit ships from our factory without oil. It must be
properly serviced with fuel and oil before operation.
If you have any questions regarding the assembly of your
generator, call our help line at 1-877-338-0999. Please
have your serial number and model number available.
Unboxing
1. Set the shipping carton on a solid, flat surface.
2. Remove everything from the carton except the
generator.
3. Using the frame of the unit, carefully remove
the generator from the box. (two people lifting is
recommended)
The recommended oil type is 10W-30 automotive oil.
NOTE
Add Engine Oil
DO NOT attempt to crank or start the engine before
it has been properly filled with the recommended
type and amount of oil. Damage to the generator as
a result of failure to follow these instructions will
void your warranty.
CAUTION
Check oil often during the break-in period. Refer to
the Maintenance section for recommended service
intervals.
NOTE
Add Engine Oil Cont’d.
The engine is equipped with a low oil shut-off and
will stop when the oil level in the crankcase falls
below the threshold level.
CAUTION
The generator rotor has a sealed, pre-lubricated ball
bearing that requires no additional lubrication for
the life of the bearing.
NOTE
Full Synthetic 5W-30

We consider the first 5 hours of run time to be
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.
NOTE
Once oil has been added, a visual check should show
oil about 1-2 threads from running out of the fill hole.
If using the dipstick to check oil level, DO NOT screw
in the dipstick while checking.
NOTE
1. Place the generator on a flat, level surface.
2. Remove oil fill cap/dipstick to add oil.
3. Add up to 0.6 qt. (0.6 L) of oil (not included) and
replace oil fill cap/dipstick. DO NOT OVERFILL.
4. Check engine oil level daily and add as needed.

10
100302 ENGLISH
Add Engine Oil Cont’d.
Synthetic oil may be used after the 5 hour initial
break-in period. Using synthetic oil does not
increase the recommended oil change interval.
NOTE
Weather will affect engine oil and engine
performance. Change the type of engine oil used
based on weather conditions to suit the engine
needs.
NOTE
ASSEMBLY
Add Fuel
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
1/4 in. (6.4 mm) of space left in the tank is required
for fuel expansion, more than 1/4 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.
Use regular unleaded gasoline with a minimum
octane rating of 85.
Do not mix oil and gasoline.
Fill tank to approximately 1/4 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
6. Screw on the fuel cap and wipe away any spilled
fuel.

11
ENGLISH 100302
ASSEMBLY
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
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 Cont’d.

100302 ENGLISH 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.

OPERATION
Economy Control Switch
The Economy Control switch can be activated in order to
minimize fuel consumption and noise while operating the
unit during times of reduced electrical output, allowing
the engine speed to idle during periods of non-use. The
engine speed automatically returns to normal when an
electrical load is connected. When the economy switch is
off, the engine runs at normal operating speed.
Starting the Engine Cont’d.
For periods of high electrical load or momentary
fluctuations, the Economy Control Switch should be
turned OFF.
WARNING
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.
NOTE
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
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 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.
Keep choke in “Choke” position for only 1 pull
of the recoil starter. After first pull, push choke
in 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.
NOTE
6. Pull the starter cord slowly until resistance is felt
and then pull rapidly.
7. As engine warms up, push the choke lever in to the
“Run” position.

14
100302 ENGLISH OPERATION
While charging a device do not place on the
exhaust side of the generator. Extreme heat caused
by exhaust can damage the device, and cause a
potential fire hazard.
WARNING
Do not operate a device while it is plugged in to the
12V DC outlet.
Prolonged exposure to engine exhaust can cause
serious injury or death.
WARNING
12V DC Outlet
The 12V DC outlet can be used with the supplied
charge cable and USB charger and other commercially
available 12V DC automotive style plugs. The DC output
is unregulated and can damage some products. Confirm
your accessory input voltage range is at least 12-24V
DC. When using the DC outlet turn the Economy mode
switch to the “OFF” position.
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. Turn the engine 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.
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.
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.
Never exceed the specified capacity when adding
loads to the generator.

ENGLISH 100302
OPERATION
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.
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.
