Power Management
Use the following formula to convert voltage and amperage to
watts:
Volts
×
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.

NOTICE
Never exceed the specified capacity when adding loads to
the generator.
GFCI
Your generator is equipped with ground fault circuit interrupter
(GFCI) receptacles. In the event of a ground fault, a GFCI trips
automatically to stop the flow of electricity and prevent serious
injury. The green indicator light (A) on the receptacle will also
turn off. Press the “
RESET
” (B) button located on the front of
the receptacle to restore flow of electricity. The indicator 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” (C) button located on the front of the
receptacle to trip the device. 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 come back on or if the GFCI cannot be reset
then it must be replaced.

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.
4. Let the engine run until fuel starvation has stopped the
engine. This usually takes a few minutes.
5. Press the ignition switch to the “OFF” position.
Important:
Always ensure that the fuel valve and the ignition
switch are in the “OFF” position when the generator is not in
use.

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 3
½
% 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.
