OPERATION
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 if operating
by gas.
4. Turn the LPG cylinder knob to the “CLOSE” or off
position if operating by LPG.
5. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.
6. Press 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
generator is not in use.
When turning off the generator after LPG operation,
make sure the LPG cylinder knob is in the fully
closed position.
NOTE
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
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 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.
