OPERATION
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.
The part number and recommended minimum altitude
for the application of the high altitude carburetor main
jet is listed in the following table.
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.
The owner/operator is responsible for all periodic
maintenance.
Complete all scheduled maintenance in a timely manner.
Correct any issue before operating the generator.
Never operate a damaged or defective generator.
Tampering with the factory set governor will void
your warranty.
Engine Maintenance
To prevent accidental starting, remove and ground spark
plug wire before performing any service.
Oil
Change oil when the engine is warm. Refer to the oil
specification to select the proper grade of oil for your
operating environment.
1. Remove the oil drain plug with a 12 mm socket and
extension (not included).
2. Allow the oil to drain completely.
3. Replace the drain plug.
4. Remove oil fill cap/dipstick to add oil.
5. Add up to 1.2 qt. (1.1 L) of oil and replace oil fill
cap/dipstick. DO NOT OVERFILL.
6. Dispose of used oil at an approved waste
management facility.
