4. OPERATING INSTRUCTIONS
When starting the generator after adding fuel for the first time or after long term
storage, or after running out of fuel, turn the fuel valve to the "on" position, then
wait for 10 to 20 seconds before starting the engine.
4.1 High Altitudes
At high altitude, the standard carburetor air-fuel mixture will be excessively 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. If you
always operate the generator at altitudes higher than 5000 feet or 1500 meters above sea level, have your
authorized dealer install a high altitude main jet.
Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 1000 feet
or 305 meter increase in altitude. The effect of altitude on the horsepower will be greater than this if no
carburetor modification is made.
Operation of the generator at an altitude lower than the carburetor is jetted for
may result in reduced performance, overheating, and serious engine damage
caused by an excessively lean air/fuel mixture. Be sure to have any modification
reversed at lower altitudes.
4.2 Ambient Temperature
Generator output generally de-rates 1% for every 10° F (5.5° C) above 85° F (29° C). The normal operating
range of the generator is -20° to 113° F (-29° to 45° C).
Do not operate the generator when the ambient temperature is below -20° F
(-29° C)
Do not operate the generator when the ambient temperature is above 113° F
(45° C)

To prevent electrical shock from faulty
appliances, the generator should be
grounded. Connect a length of heavy
cable between the generator's grounding
terminal and an external ground source.
Connections for standby power to a building's electrical
system must be made by a qualified electrician and must comply with all
applicable laws and electrical codes. Improper connections can allow electrical
current from the generator to back feed into the utility lines. Such back feed
may electrocute utility company workers or others who contact the lines during
a power outage. When utility power is restored the generator may explode, burn,
or cause fires in the building's electrical system.
Do not connect the generator to an automatic transfer device. Severe damage
to the inverter module may result.
Limit operation requiring maximum power to 30 minutes.
For continuous operation do not exceed the rated power of 3000 Watts or 25
Amps.
Do not exceed the current limit specified for any one receptacle.
Do not modify or use the generator for other purpose other than what it was
intended.Also observe the following when using the generator:
oDo not attempt to connect generators in parallel.
oDo not connect an extension to the exhaust pipe.
oDo not operate with any covers removed or in a closed compartment
When an extension cable is required, make sure you use the proper size and
length.
o16 Gauge Cords-Any 16 gauge cord between 0 and 100 feet long will
adequately handle tool and appliance loads up to 10 amps.
o14 Gauge Cords- a 14 gauge cord between 0 and 50 feet long will
adequately handle loads between 10 and 15 amps.
o12 Gauge Cords- If your load is between 10 and 15 amps and the length
of the cord is 50 to 100 feet, you need a 12 gauge cord to safely power
any tool.
Keep the generator away from other electric cables or wires such as commercial
power supply lines.
You may use the DC receptacle when usingAC supply.
