Operation
Rev 41331-20110330 English 11
Operation
Generator Location
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.
This generator must have at least five feet of
clearance from combustible material. Leave
at least three feet of clearance on all sides of
the generator to allow for adequate cooling,
maintenance and servicing.
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.
Surge Protection
CAUTION
Voltage fluctuation may impair the proper
functioning of sensitive electronic equipment.
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.
Starting the Engine
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 fuel valve to the “On” position.
4. Move the choke lever to the “Choke”
position.
5. Turn the key to the “On” position.
6. ELECTRIC START: Turn the ignition
key to the “Start” position and hold until
engine starts. If the engine fails to start
within five seconds, release the key and
wait at least ten seconds before
attempting to start the engine again.
7. RECOIL START: Pull the starter cord
slowly until resistance is felt and then
pull rapidly
8.As engine warms up, move the choke
lever to the full “Run” position.
NOTE
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
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.

Operation
12 Rev 41331-20110330 English
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.
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 ignition switch to the “Off”
position.
4. Turn the fuel valve to the “Off” position.
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.
NOTE
Never exceed the generator capacity when
adding loads.

WARNING
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.
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 3 ½ % for every 1000
feet of elevation above sea level. This is
a natural trend and cannot be changed
by adjusting the engine. At sufficiently
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.
