Stopping Generator
Stopping Generator
In an emergency:
Press engine control switch to STOP position.
In normal use:
1. Turn OFF any connected appliances and unplug any
connected power cords.
2. Allow generator to run for 2-3 minutes.
3. Press engine control switch to STOP position.
4. Turn fuel valve to OFF position.
High-Altitude Operation
At high altitudes, standard carburetor air-fuel mixture will
be rich. Performance will decrease and fuel consumption
will increase.
High-altitude performance can be improved by installing a
smaller diameter main fuel jet in the carburetor and then
readjusting the pilot screw. If you always operate the
engine at altitudes higher than 5000 feet (1500 meters)
above sea level, have an authorized generator dealer per-
form this carburetor modification.
Even with suitable carburetor jetting, engine horsepower
will decrease approximately 3.5% for each 1000 foot (300
meters) increase in altitude above sea level. The effect of
altitude on horsepower will be greater than this if no car-
buretor modification is made.
Powering Appliances
NOTE:
In this manual, the term “appliance” refers to any electri-
cal device that can be connected to generator for power.
Rules for Powering Appliances
• Plan carefully: Before using the generator to power
appliances, take time to add power ratings (watt-
age) of each appliance and verify that total wattage
does not exceed rated output of generator. Power
rating information can usually be found on an appli-
ance’s product label, stamped inside, or on the
back of the appliance.
See Table 1 for a listing of
average appliance wattage requirements.
• NEVER overload: Circuit breakers will stop the flow
of electricity from the generator to the appliance if the
generator is overloaded. This will be indicated by a
“tripped” breaker. If this happens, power off and dis-
connect appliance(s), wait a few minutes, and then
push circuit breaker to reset.
NOTICE
If the engine is jetted for high-altitude and is used at a lower
altitude, it will run a lean air-fuel mixture that results in
reduced performance, possible over-heating, and possible
serious engine damage.
NOTICE
NEVER start generator with electrical appliances plugged in
and turned on.
Faulty appliances and power cords can result in elec-
trical shock.
• Before attempting to power an appliance, be sure gen-
erator has been properly grounded, and that appliance
and power cord are in good working order.
• Keep the generator away from other electric cables or
wires including commercial power supply lines.
• Do not use generator for any purpose other than its
intended use.
• Do not parallel connect generators or lengthen the
exhaust pipe.
• Do not connect generator to any household circuit,
otherwise it may destroy generator or home electric
equipment.
Medical and Life Support Uses
• In case of emergency, call 911 immediately.
• Never use this product to power life support devices or
life support appliances.
• Never use this product to power medical devices or
medical appliances.
• Inform your electricity provider immediately if you or
anyone in your household depends on electrical equip-
ment to live.
• Inform your electrical provider immediately if a loss of
power would cause you or anyone in your household to
experience a medical emergency.
