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.

Parallel Operation
The Champion model 100302 is parallel ready and can
be operated in parallel with another Champion unit to
increase the total available electrical power. A Champion
model 100319 parallel kit (optional equipment) is
required for parallel operation. For a list of compatible
models or to order a parallel kit, please call customer
service at 1-877-338-0999 or visit
www.championpowerequipment.com.
Detailed instructions for parallel kit installation and
operation of the connected generators are provided in the
parallel kit owner’s manual.
Overload Operation
The overload indicator light will turn on when the rated
load is exceeded. When the maximum load is reached,
the LED will blink and cut power to the receptacles.
To recover the power, shut down the generator, wait until
the light turns off and restart the generator.
