Carbon Monoxide Poisoning
9CO gas is toxic and can cause serious injury or
death.
9Get fresh air and seek medical care immediately, if
you are suspected to be inhaled carbon monoxide.
9Early symptoms of carbon monoxide exposure
include headache, fatigue, shortness of breath,
nausea, and dizziness and so on. Continued expo-
sure to carbon monoxide can cause loss of mus-
cular coordination, loss of consciousness, and
then result in death.
9This generator is equipped with the CO SENSOR
system that automatically stops the engine before
the surrounding carbon monoxide concentration
increases to a dangerous concentration.
9Do not remove or modify the CO SENSOR sys-
tem.
9Make sure that the CO SENSOR system works
correctly.
9The CO SENSOR cannot prevent all danger asso-
ciated with or caused by carbon monoxide. Pay
careful attention to the location of the generator.
9If the CO SENSOR stopped the generator, relo-
cate the generator and address symptoms of car-
bon monoxide poisoning prior to restart the gener-
ator.
9Install battery-operated or plug-in carbon monox-
ide alarms to alert you to potentially dangerous
levels of carbon monoxide in accordance with the
alarm’s instructions.

Connection
WARNING
Before the generator can be connected to a build-
ing’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the build-
ing’s main fuse box. The switch is the connection
point for generator power and allows selection of
generator or main line power to the building. This
will prevent the generator from charging the main
power line (backfeeding) when the main power
supply has failed or has been turned off for line
repair. Backfeeding can electrocute or injure line
maintenance personnel. Also, generator and build-
ing electrical system damage can occur when nor-
mal operating power returns if unit is used without
an isolation switch.
Extension Cord Notes
Extension cords should be protected by a tough flexi-
ble rubber sheath (IEC 245) or the equivalent to with-
stand mechanical stresses.
