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.
Never exceed the specified capacity when adding
loads to the generator.
NOTE
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 304.8 m
(1,000 ft.) 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.
