Then place the main breaker (AA) in
the ON position. Connect electrical
loads, see Connecting Electrical
Loads under Operation.
NOTE: If any unusual noise or vibration
is noticed, stop the engine and refer to
the troubleshooting section.
STOppING GENERATOR
(FIG. 3, 9)
To stop the engine in an emergency,
move the engine On/Off switch (Z) to
the OFF position.
To Stop Generator During Normal
Operation:
1. Disconnect all electrical loads
attached to the generator.
2. Move the engine On/Off switch (Z)
in the OFF position.
3. Turn the fuel

position as
shown.
CONNECTING ELECTRICAL
LOADS (FIG. 3)
1. Allow the engine to warm up for
five minutes. Then place the main
breaker (AA, Fig. 3) in the ON
position.
Connect loads in the following
manner to prevent damage to
equipment:
2. Connect inductive load equipment
first. Inductive loads consist of
refrigerators, freezers, water
pumps, air conditioners or small
hand tools. Connect the items that
require the most wattage first.
3. Connect the lights next.
4. Voltage sensitive equipment
should be the last equipment
connected to the generator. Plug
voltage sensitive appliances such
at TV's, VCR's, microwaves,
ovens, computers and cordless
telephones into a UL listed voltage
surge protector, then connect the
UL listed voltage surge protector
to the generator.
WARNING: Failure to connect and
operate equipment in this sequence can
cause damage to equipment and will
void the warranty on your generator.
OpERATING hEAVY LOADS
DO NOT exceed the current limit
specified on the control panel for any
receptacle.
hIGh ALTITUDE OpERATING
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.
High altitude performance can be
improved by specific modifications to
the carburetor. If you always operate
your engine at altitudes above 1,524
meters (5,000 feet), have your authorized
service center perform a carburetor
modification.
Even with a carburetor modification,
engine horsepower will decrease about
3.5% for each 300 meter (1,000 feet)
increase in altitude. The effect of altitude
on horsepower will be greater than this
if no carburetor modification is made.
A decrease in engine horsepower will
decrease the power output of the
generator.
NOTE: When the carburetor has been
modified for high altitude operation,
the air-fuel mixture will be too lean for
low altitude use. If the generator is
used at low altitudes after a carburetor
modification, the carburetor may cause
the engine to overheat and result in
serious engine damage. For use at low
altitudes, have your authorized service
center return the carburetor to original
factory specifications.
hIGh AND LOW TEmpERATURE
OpERATION
Air temperature affects generator
output. Output drops 1% for each 10ºF
temperature rise above 60º F. Very low
temperature may cause the engine to
be hard to start.
