Carburetor Modification for High Altitude
Operation
At high altitude, the standard carburetor air-fuel
mixture will be too rich. Performance will
decrease, and fuel consumption will increase. A
very rich mixture will also foul the spark plug and
cause hard starting.
If the generator operates at high altitude, change the
main nozzle or adjust the idling screw of carburetor
If the generator always operates at altitude above
Caution
Every generator delivers one controller with
the generator. If the controller is lost, contact
your dealer to purchase and decode a new
one.

1 000 meters contact an authorized Cobra
servicing to modify the carburetor
Generator output power should be modified
according to the altitude and ambient
temperature The correction factor refers to
chapter 13.
WARNING
If the carburetor has been modified for high
altitude operation, the air-fuel mixture will be
too lean for low altitude use. Operation at low
altitude may cause the engine to overheat
and result in serious engine damage. The
carburetor needs return to original
specifications.
6. GENERATOR USE
WARNING
Be sure to ground the generator when the
connected electrical appliance is grounded.
Do not connect to the building’s electrical
system, in order to avoid the electric shocks
and fires.

WARNING
NOTE
•The DC receptacle can be used while the AC
power is in use. If both are used at the same
time, be sure not to exceed the total power for
AC and
•(AC:2.6kVA, DC:5A)
•Most of motor appliances require more than
their rated wattage, when starting.
6.1) DC Application
The DC receptacle, 15-30V under no load condition,
may be used for charging 12V battery only.
NOTE
In DC operation, turn the ECON SW to the
“OFF” ( ) position.
6.1.1) Disconnect the vehicle battery ground cable
from the negative battery terminals.
6.1.2) Connect the DC terminals to battery
terminals with the charging cable
CAUTION
Connect red lead to positive battery terminal and
black lead to negative battery terminal.
6.1.3) Turn ECON SW to “OFF” ( ) position and
then start engine
