CONNECTIONS TO A BUILDING ELECTRICAL SYSTEM
Connections for standby power to a building electrical system must be made by a qualified electrician, The
connection must isolate the generator power from utility power, and must comply with all applicable laws
and electrical codes.
WARNING! Improper connections to a building electrical system can allow electrical current
from the generator to feedback into the utility lines. Such feedback may electrocute utility company
workers or others who contact the lines during a power outage, and the generator may explode, burn, or
cause fires when utility power is restored. Consult the utility company or a qualified electrician.
GROUND SYSTEM
These portable generators have a system ground that connects generator frame components to the
ground terminals in the AC output receptacles. The system ground is not connected to the AC neutral
wire. If the generator is tested by a receptacle tester, It will not show the same ground circuit condition as
for a home receptacle.
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 dose 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.
NOTICE! Substantial overloading will switch off the AC circuit protector. Exceeding the time
limit for maximum power operation OFF, but will shorten the service life of the generator.
Limit operation requiring maximum power to 30 minutes. Maximum power is: 3,200VA.
For continuous operation, do not exceed the rated power. Rated power is: 3,000VA.

9
In either case, 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 engines and make sure the output indicator lights(green) Comes on. 2.
Plug in the appliance require more than their rated wattage for startup
If the generator is overloaded(in excess of 3,200 VA),or if there is a short circuit in a connected appliance,
the overload indicator light(red) will go ON, The overload indicator light(red)will stay ON, and after about
four 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 or an overload. 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.
NOTICE! When an electric motor is started, the overload indicator light(red) may come on,
This is normal if the overload indicator light(red)goes off after about four seconds. If the overload indicator
light(red) stays on, consult your generator dealer.

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, 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.

11
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 to the OFF position.
ECO-THROTTLE SWITCH
HIGH ALTITUDE OPERATION
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 servicing dealer perform
this carburetor modification. This engine, when operated at high altitude with the 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.
NOTICE! 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.
5. PRE-OPERATION CHECK
ENGINE OIL
NOTICE! Engine oil is a major factor affecting engine performance service life. Non detergent and
2-stroke engine oils will damage the engine and are not recommended.
Check the oil level before each use with the generator on a level surface and the engine stopped. Use
4-stroke motor oil that meets or exceeds the requirements for API service classification SF, Always
check the API SERVICE label on the oil container to be sure it includes the letter SF. SAE 15W-40 is
recommended for generator, all-temperature use. Other viscosities shown in the chart may be used
when the average temperature in your area is within the indicated range.

12
EN
AMBIENT TEMPERATURE
1．Loosen the cover screw and remove the protecting cover. 2．Remove
the oil filler cap and wipe the dipstick clean.
3. Check the oil level by inserting the dipstick into the dipstick into the filer neck without screwing it in.
4. If the level is low, fill to top of the oil filler neck with the recommended oil.
5. Reinstall the left- side maintenance cover and tighten the cover screw securely.
REFUELING
With the engine stopped, remove the fuel tank cap and check the fuel level. Refill the fuel tank if the fuel
level is low.
WARNING! Gasoline is highly flammable and explosive.
You can be burned or seriously injured when handing fuel.
•Stop the engine and keep heat, sparks, and flame away.
•Handle fuel only outdoors.
•Wipe up spills immediately.
Refuel in a well-ventilated area with the engine stopped. If the engine has been running, allow it to cool
first. Refuel carefully to avoid spilling fuel. Do not fill above the upper limit mark. After refueling, tighten the
fuel tank cap securely.

13
Never refuel the engine inside a building where gasoline fumes may reach flames or sparks. Keep
gasoline away from appliance pilot lights, barbecues, electric appliances, power tools, etc. Spilled fuel
is not only a fire hazard, it causes environmental damage. wipe up spills immediately.
FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating of 86 or higher. This engine is certified to operate on
unleaded gasoline. Unleaded gasoline produces fewer engine and spark plug deposits and extends
exhaust system life.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Occasionally you may hear a light ”spark knock” or ”pinging”（metallic rapping noise）while operating
under heavy loads. This is no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of gasoline.
If spark knock or pinging persists, see an authorized generator dealer.
NOTICE! Running the engine with persistent spark knock or pinging can cause engine
damage.
Running the engine with persistent spark knock or pinging is misuse, and the Distributor’s Limited
Warranty does not cover parts damaged by misuse.
OXYGENATED FUELS
Some conventional gasoline are being blended with alcohol or an ether compound. These gasoline are
collectively referred to as oxygenated fuels, To meet clean air standards, some areas of the United States
and Canada use oxygenated fuels to help reduce emissions.
If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.
Before using an oxygenated fuel, try to confirm the fuel’s contents. Some states/provinces require this
information to be posted on the pump.
The following are the EPA approved percentages of oxygenates:
ETHANOL—(ethyl or grain alcohol)10% by volume You may use gasoline containing up to 10% ethanol
by volume. Gasoline containing ethanol may be marketed under the name ”Gasohol”. MTBE—(methyl
tertiary butyl ether)15% by volume You may use gasoline containing up to 15% MTBE by volume.
METHANOL—methyl or wood alcohol）5% by volume You may use gasoline containing up to 5%
methanol by volume as long as it also contains cosolvents and corrosion inhibitors to protect the fuel
system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance
problems. It may also damage metal, rubber, and plastic parts of your fuel system.
If you notice any undesirable operating symptoms, try another service station or switch to another brand of
gasoline.
Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates mentioned above are not covered under warranty. 6. STARTING THE

9. MAINTENANCE
THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical, and trouble-free operation. It will also help reduce
air pollution.
WARNING! Improper maintenance, or failure to correct problem before operation, can cause
a malfunction in which you can be seriously hurt or killed.
Always follow the inspection and maintenance recommendations and schedules in this owner’s manual.
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 our technician or other qualified mechanic.
The maintenance schedule applies to normal operating 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.
Remember that your servicing dealer knows your generator best and is fully equipped to maintain and
repair it.
To ensure the best quality and reliability, use only new, genuine parts or their equivalents for repair or
replacement. 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.
WARNING! Failure to properly follow maintenance instructions and precautions can cause
you to be seriously hurt or killed.
Always follow the procedures and precautions in the owner’s manual.
Safety precautions
•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 the instructions before you begin, and make sure you have the tools and skills required.
•To reduce the possibility of fire or explosion, be careful when working around gasoline. Use only a
nonflammable solvent, not gasoline, to clean parts, Keep cigarettes, sparks, and flames away from all
fuel-related parts.

EN
EMISSION CONTROL SYSTEM INFORMATION
SOURCE OF EMISSIONS
The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of
hydrocarbons and oxides of nitrogen are very important because, under certain conditions, they react to
form photochemical smog when subjected to sunlight.
We utilize lean carburetor settings and other systems to reduce the emissions of carbon monoxide,
oxides of nitrogen, and hydrocarbons.
The following instructions and procedures must be followed in order to keep the emissions from your
engine within the emission standards.
PROBLEMS THAT MAY AFFECT EMISSIONS
If you are aware of any of the following symptoms, have your engine inspected and repaired by your
servicing dealer.
•Hard starting or stalling after starting.
•Rough idle.
•Misfiring or backfiring under load.
•Afterburning (backfiring).
•Black exhaust smoke or high fuel consumption
REPLACEMENT PARTS
The emission control systems on your engine were designed, built, and certified to conform with EPA and
California emission regulations. We recommend the use of genuine parts wherever you have
maintenance done, These original-design replacement parts are manufactured to the same standards as
the original parts, so you can be confident of their performance. The use of replacement parts that are
not of the original design and quality may impair the effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect
emission performance. The manufacturer or rebuilder of the part must certify that use of the part will not
result in a failure of the engine to comply with emission regulations.
MAINTENANCE
Follow the maintenance schedule. Remember that this schedule is based on the assumption that your
machine will be used for its designed purpose. Sustained high-load or high-temperature operation, or use
in unusually wet or dusty conditions, will require more frequent service.
