OPERATION
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.
WARNING
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.

GFCI
Your generator is equipped with two (2) Ground Fault
Circuit Interrupter (GFCI) duplexes. In the event of a
ground fault, a GFCI trips automatically to stop the
flow of electricity and prevent serious injury. The green
indicating light on the receptacle will also turn off. Press
the reset button located on the front of the receptacle to
restore flow of electricity. (A) The green indicating light
will also turn back on. GFCI does not protect against
circuit overloads.
To ensure proper operation of the GFCI duplex, perform
this test monthly:
1. With the generator running, plug a lamp into the
GFCI receptacle. Turn the lamp on.
2. Press the “Test” button located on the front of
the receptacle to trip the device. (A) This should
immediately stop the flow of electricity and shut off
the lamp. If the electricity is not stopped, do not use
this receptacle until is has been serviced or replaced.
3. Press the “Reset” button located on the front of the
receptacle to restore the flow of electricity. If the
indicator light does not go out and come back on or
if the GFCI cannot be reset then it must be replaced.
A
For the GFCI receptacles to work properly the neutral wire
must be bonded to ground or to the generator frame. Your
Champion generator comes with the neutral wire already
bonded to the frame. If the bonding wire is removed then
the GFCI receptacles will no longer function as designed.
If the neutral bonding wire is removed to accommodate
a transfer switch installation for connection to a house
or building, then the transfer switch must not switch off
the neutral connection to ground within the building.
Champion Power Equipment recommends that you consult
with a licensed, local electrician. Due to the variety of
local codes, we cannot specifically advise you regarding
modifications to the wiring of your portable generator.
