100523 - 3100W PORTABLE INVERTER GENERATOR
MAINTENANCE
20
Detailed instructions for parallel kit installation and operation
of the connected generators are provided in the parallel kit
owner’s manual.
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 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.

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 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 3
½
% for every 1000 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, 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 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 high altitude jet part number corresponding to the
carburetor code found on your particular carburetor.

WARNING
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.
MAINTENANCE
Make certain that the generator is kept clean and stored
properly. Only operate the unit on a flat, level surface in a clean,
dry operating environment. DO NOT expose the unit to extreme
conditions, excessive dust, dirt, moisture or corrosive vapors.
!
WARNING
Never operate a damaged or defective generator.
!
WARNING
Improper maintenance will void your warranty.

NOTICE
Maintenance, replacement, or repair of emission control
devices and systems may be performed by any non-road
engine repair establishment or individual.
The owner/operator is responsible for all periodic maintenance.
Complete all scheduled maintenance in a timely manner.
Correct any issue before operating th e generator.

Technical Support Team at 1-877-338-0999.
Cleaning the Generator
!
CAUTION
DO NOT spray engine with water.
Water can enter the generator through the cooling slots and
damage the generator windings. It can also contaminate the
fuel system.
