Please consult your local authority. In some areas,
generators must be registered with the local utility.
Generators used at construction sites may be subject to
additional rules and regulations.
This generator must have at least five feet of clearance
from combustible material. Leave at least three feet
of clearance on all sides of the generator to allow for
adequate cooling, maintenance and servicing.
Place the generator in a well-ventilated area far
away from windows door, and vents. DO NOT place
the generator near vents or intakes where exhaust
fumes could be drawn into occupied or confined
spaces. Carefully consider wind and air currents when
positioning generator.
Even when using a generator correctly, carbon monoxide
may leak into the home. ALWAYS use a battery-powered
or battery- backup CO alarm in the home.
If you start to feel sick, dizzy, or weak after the
generator has been running, move to fresh air RIGHT
AWAY. See a doctor, you could have carbon monoxide
poisoning.

REV 72531i-20110425 10
72531i ENGLISH
Economy Control Switch
The Economy Control switch can be activated in order to
minimize fuel consumption and noise while operating the
unit during times of reduced electrical output, allowing
the engine speed to idle during periods of non-use. The
engine speed returns to normal when an electrical load is
connected. When the economy switch is off, the engine
runs at normal speed continuously.
7. Pull the starter cord slowly until resistance is felt and
then pull rapidly.
8. As engine warms up, slide the choke lever left to the
“Run” position.
If the engine starts but does not stay running make
certain that the generator is on a flat, level surface.
The engine is equipped with a low oil sensor that
will prevent the engine from running when the oil
level falls below a critical threshold.
NOTE
Connecting a generator to your electric utility
company’s power lines or to another power source
may be against the law. In addition this action,
if done incorrectly, could damage your generator
and appliances and could cause serious injury or
even death to you or a utility worker who may be
working on nearby power lines. If you plan to run a
portable electric generator during an outage, please
notify your electric utility company immediately
and remember to plug your appliances directly
into the generator. Do not plug the generator into
any electric outlet in your home. Doing so could
create a connection to the utility company power
lines. You are responsible for ensuring that your
generator’s electricity does not feed back into the
electric utility power lines.
If the generator will be connected to a building
electrical system, consult your local utility company
or a qualified electrician. Connections must isolate
generator power from utility power and must comply
with all applicable laws and codes.
NOTE
OPERATION
