Operation At High Altitude - Champion 100554 Operator's Manual

100554 - 3500W WIRELESS START GENERATOR
Manual Stop
1. Turn off and unplug all electrical connected 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. Press the ignition switch to the "OFF" position.
4. If generator was started electrically, press the battery
switch to the "OFF" position.
5. Turn the fuel valve to the "OFF" position.
Important: Always ensure that the fuel valve, the ignition
switch, and the battery switch are in the "OFF" position when
the generator will not be used for an extended period of time.
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.

Operation at High Altitude

The density of air at high altitudes 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 ft. of elevation above sea
level. 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, CPE can provide a high altitude carburetor main jet.
The alternative main jet and installation instructions can be
obtained by contacting our Technical Support Team. Installation
instructions are also available in the Technical Bulletin area of
the CPE website.
The part number and recommended minimum altitude for the
application of the high altitude carburetor main jet is listed in
the following table.
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 high altitude jet part number corresponding to the
carburetor code found on your particular carburetor.
Carb. Code High Alt. Jet Part Number
100082378
Z926-1
100123767
Operation using the alternative main jet at elevations lower
than the recommended minimum altitude can damage the
engine. For operation at lower elevations, the originally
supplied 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.
