Battery Charging
1. Before connecting the battery charging cable (included)
to a battery that is installed in a vehicle, disconnect the
vehicle battery ground cable from the negative (–) battery
terminal.
2. Plug the battery charging cable into the 12V DC receptacle
of the generator.
3. Connect the red (+) battery charger lead to the red (+)
battery terminal.
4. Connect the black (–) battery charger lead to the black (–)
battery terminal.
5. Start the generator.
Important: The 12V DC outlet is ONLY to be used with the
supplied 12V DC battery charging cable. The 12V DC output
is unregulated and will damage other 12V DC products. When
using the 12V DC outlet, turn the Economy mode switch to the
“OFF” position. Be sure all electric devices including the lines
and plug connections are in good condition before connection to
the generator.
 CAUTION
Do not start the vehicle while the battery charging cable is
connected and the generator is running. It will not give the
battery a boost of power. The vehicle or the generator may
be damaged. Charge only vented wet lead acid batteries.
Other types of batteries may burst, causing personal injury
or damage.

NOTICE
Be sure all electric devices including the lines and plug
connections are in good condition before connection to the
generator.
Stopping the Engine
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 engine switch to the “OFF” position.
4. Turn the fuel valve to the “OFF” position.
Important: Always ensure that the fuel valve and the engine
switch are in the “OFF” position when the generator will not be
used for an extended period of time.

NOTICE
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.
