Smart Generators Operating Instructions
HIGH ALTITUDE
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.
Operation at an altitude that differs
from that at which this engine was
certified, for extended periods of
time, may increase emissions.
High altitude performance can be
improved by specific modifications
to the carburetor. If you always
operate your generator at altitudes
above 5,000 feet (1,500 meters),
have your dealer perform this
carburetor modification. This
engine, when operated at high
altitude with the carburetor
modifications for high altitude use,
will meet each emission standard
throughout its useful life. Even with
carburetor modification, engine
horsepower will decrease about
3.5% for each 1,000-foot
(300-meter) increase in altitude.
The effect of altitude on
horsepower will be greater than
this if no carburetor modification is
made.
NOTE:When the carburetor has been
modified for high altitude operation,
the air/fuel mixture will be too lean for
low altitude use. Operation at altitudes
below 5,000 feet (1,500 meters) with
a modified carburetor may cause the
engine to overheat and result in serious
engine damage. For use at low altitudes,
have your servicing dealer return the
carburetor to original factory
specifications.
Operation (Gasoline)
ELECTRIC START
NOTE: Read Operator's Manual carefully
before operating this unit. Always
make sure the unit is level and properly
grounded. Check engine oil before
starting.
1. Open the valve leading from the
gasoline tank to the carburetor.
2. Move choke lever to full choke. If
re-starting a warm engine, the choke
should be left in the off position. (See
Above)
3. Turn the key to the START position,
hold until engine starts.
4. When the engine starts, release
key, allowing it to return to the ON
position.
NOTE: Do not crank the engine
continuously for more than 30 seconds
at a time. If the engine does not start,
allow for a 3 minute cool down period
between starting attempts. Failure to
follow these guidelines can damage the
starter motor.
If the starter does not turn the engine
over, shut off the starter immediately.
Do not make further attempts to
start the engine until the condition
is corrected. Do not jump start using
another battery.
5. Slowly move choke lever to no
choke.
6. Allow unit to run two (2) minutes to
warm-up.
NOTE: This engine is equipped with a
"Low Oil" shutdown system for engine
protection. The engine stops when the
oil level gets too low. The engine will
not restart without adding oil. Refer to
Preparing the Generator; Engine Fuel
Capacity for instructions on adding oil.
NOTE: While the engine is idling, the
generator voltage is automatically
reduced to reduce generator
temperatures. The voltage will return
to normal levels immediately upon the
application of load.

SHUTDOWN
1. Remove all load by turning off
electrical appliances and unplugging
electric cords.
2. Allow engine to run at idle speed to
cool for two (2) minutes.
NOTE: Failure to allow the engine to cool
at idle for two (2) minutes may result in
damage to the generator.
3. Turn engine key or ignition switch
off.

Maintenance

GENERATOR MAINTENANCE
Keep all air vents clear.
Keep the generator clean. DO NOT
spray with water.
Periodically check all fasteners and
tighten, see the periodic maintenance
chart.
EVAPORATIVE EMISSION
COMPONENTS:
The unit you have purchased includes
the following components that are in
compliance with 2008 California Air
Resources Board Evaporative
Emission
Standards;
1. Fuel Hose
2. Fuel Hose Fittings
These components should be
inspected on a daily basis for cracks,
leaks, and abnormal wear. If cracking,
leaks or abnormal wear has occurred,
the components should be replaced
immediately.
ENGINE:
The engine for this generator is
governed to operate at speeds close
to 3600 RPM (60Hz) throughout the
operating load range. The no load
speed (before a load is applied) will
be just a bit higher than the load
speed and is normally set to 3750
RPM.
