7, OPERATION
AC APPLICATIONS
Before connecting an appliance or power cord to the
generator: Make sure that it is in good working order.
Faulty appliances or power cords can create a potential
for electrical shock.
If an appliance begins to operate abnormally, becomes
sluggish or stops suddenly, turn it off immediately.
Disconnect the appliance, and determine whether the
problem is the appliance, or if the rated load capacity of
the generator has been exceeded.
Make sure that the electrical rating of the tool or
appliance does not exceed that of the generator. Never
exceed the maximum power rating of the generator.
Power levels between rated and maximum may be used
for no more than 30 minutes.
Limit operation requiring maximum power to 30 minutes.
Maximum power is:
3.0 kVA
For continuous operation, do not exceed the rated power.
Rated power is:
2.8 kVA
The total power requirements (VA) of all appliances
connected must be considered. Appliance and power
tool manufacturers usually list rating information near
the model number or serial number.
AC OPERATION
1.Start the engine and make sure the output indicator
light (green) comes on.
2. Plug in the appliance.
Most motorized appliances require more than their
rated wattage for startup.
If the generator is overloaded, or if there is a short circuit
in a connected appliance, or if the inverter is overheated,
the overload indicator light (red) will come ON. The
overload indicator light (red) will stay ON, and after
about five seconds, current to the connected appliance(s)
will shut off, and the output indicator light (green) will go
OFF. Stop the engine and investigate the problem.
Determine if the cause is a short circuit in a connected
appliance, an overload, or an overheated inverter.
Correct the problem and restart the generator.
Before connecting an appliance to the generator, make
sure that it is in good order and that its electrical rating
does not exceed that of the generator. Then start the
generator and connect the appliance power cord.
DC OPERATION
The DC receptacle should ONLY be used for charging
12-volt automotive type batteries. The DC charging
output is not regulated. DC output will vary according to
the position of the Eco-Throttle switch. When the
Eco-Throttle switch is turned to the ON position and the AC
output is not used, the DC current will be about one-third
of the rated current.
ECO-THROTTLE SYSTEM
With the switch in the ON position, engine speed is
automatically lowered when loads are reduced, turned
OFF or disconnected. When appliances are turned ON or
reconnected, the engine returns to the proper speed to
power the electrical load. In the OFF position, the
Eco-Throttle system does not operate.
Appliances with large start-up power demands may not
allow the engine to reach normal operating rpm when
they are connected to the generator. Turn the Eco-Throttle
to the OFF position and connect the appliance to the
generator. If the engine still will not reach normal
operating speed, check that the appliance does not
exceed the rated load capacity of the generator.
If high electrical loads are connected simultaneously, turn
the Eco-Throttle switch to the OFF position to reduce
voltage changes.
The Eco-Throttle system is not effective for use with
appliances that require only momentary power. If the tool
or appliance will be turned ON and OFF quickly, the
Eco-Throttle switch should be in the OFF position.

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 servicing dealer perform this
carburetor modification. This engine, when operated at
high altitude with the carburetor modifications fo r 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 ef-fect of altitude on horsepower
will be greater than this if no carburetor modification is
made.
8. STOPPING THE ENGINE
HIGH ALTITUDE OPERATION
At high altitude, the standard carburetor air/fuel mixture
will be too rich. Performance will decrease, and fuel
In an emergency:
1, To stop the engine in an emergency, turn the engine
switch to the OFF position.
In normal use:
1. Unplug appliances from the generator receptacles.
2. Turn the engine switch to the OFF position.
3. Turn the fuel valve lever to the OFF position.
9.MAINTENANCE
THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical, and
trouble-free operation. It will also help reduce air
pollution.
To help you properly care for your generator, the
following pages include a maintenance schedule, routine
inspection procedures, and simple maintenance
procedures using basic hand tools. Other service tasks
that are more difficult, or require special tools, are best
handled by professionals and are normally performed by
a Unitedpower technician or other qualied mechanic.
The maintenance schedule applies to normal operatin g
conditions. If you operate your generator under severe
conditions, such as sustained high-load or
high-temperature operation, or use it in unusually wet or
dusty conditions, consult your servicing dealer for
recommendations applicable to your individual needs
and use.
Maintenance, replacement, or repair of the emission
control devices and systems may be performed by any
engine repair establishment or individual, using parts
that are ''certified'' to EPA standards.
MAINTENANCE SAFETY
Some of the most important safety precautions follow.
However, we cannot warn you of every conceivable hazard
that can arise in performing maintenance. Only you can
decide whether or not you should perform a given task.
●Make sure the engine is off before you begin any
maintenance or repairs. This will eliminate several
potential hazards:
-Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you
operate the engine.
-Burns from hot parts.
Let the engine and exhaust system cool before touching.
-Injury from moving parts.
Do not run the engine unless instructed to do so.
●Read th e instructions before you begin, and make sure
you have the tools and skills required.
