1. SAFETY INSTRUCTIONS

WARNING

Operate carefully to ensure safety.

WARNING

Our generators are designed to give safe and

depend-able service if operated according to instructions. Read and understand the Owner's Manual before operating the generator. Failure to do so could result in personal injury or equipment damage.

WARNING

Exhaust gas contains poisonous carbon monoxide.

Never run the generator in an enclosed area. Be sure to provide adequate ventilation.

WARNING

The muffler becomes very hot during operation and

remains hot for a while after stopping the engine. Be careful not to touch the muffler while it is hot.

The engine exhaust system will be heated during

operation and remain hot immediately after stopping the engine. To prevent scalding, pay attention to the warning marks attached to the generator.

Gasoline is extremely flammable and explosive under certain conditions.

Refuel in a well ventilated area with the engine stopped.

Keep away from cigarette, smoke and sparks when re-fueling the

generator. Always refuel in a well-ventilated location.

Wipe up spilled gasoline at once. Usage of generator should be limited in ambient where the risk of fire may

be high.

WARNING

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, and when utility power is restored, the generator may explode, burn,

or cause fires in the building's electrical system.

WARNING

Always make a pre-operation inspection before you start the engine. You

may prevent an accident or equipment damage.

Place the generator at least 1m(3ft) away from buildings or other

equipment during operation.

Operate the generator on a level surface.

If the generator is tiled, fuel spillage may result.

Know how to stop the generator quickly and understand operation of all the controls. Never permit anyone to operate the generator without proper instructions.

2. Check the fuel level. Use automotive gasoline (Unleaded or low-leaded is preferred to minimize combustion chamber deposits). If the fuel level is low, refuel the fuel tank until the level as specified. Never use an oil/gasoline mixture or dirty gasoline. Avoid getting dirt, dust or water in the fuel tank. After refueling, tighten the oil rule seurely.

WARNING

Gasoline is extremely flammable and is explosive under certain conditions. Refuel in a well-ventilated area with the engine stopped.

Do not smoke or alow flames or sparks in the area where the engine is

refueled or where gasoline is stored.

Do not overfill the fuel tank (there should be no fuel above the upper limit mark). After refueling, make sure the tank cap is closed properly and securely.

Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite, if any fuel is spilled, make sure the area is dry before starting the engine.

Avoid repeated or prolonged contact with skin or breath-ing of vapor,

KEEP OUT OF REACH OF CHILDREN.

Gasoline containing alcohol

If you decide to use a generator containing alcohol (gasohol), be sure it's octane rating is at least as high as that recommended by us. There are two types of gasohol: one containing ethanol, and the other containing methanol. Do not use gasohol that contains more than 10% ethanol. Do not use gasoline containing methanol (methyl or wood alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol. Never use gasoline containing more than 5% methanol, even if it has cosolvents and corrosion inhibitors.

CAUTION

Fuel system damage or engine performance problems resulting from the use of fuel that contain alcohol is not covered under the warranty. We cannot endorse the use of fuels containing methanol since evidence of their suitability is as yet incomplete.

Before buying fuel from an unfamiliar station, try to find out if the fuel contains alcohol. If it does, confirm the type and percentage of alcohol used. If you notice any undesirable operating symptoms while using a gasoline that contains alcohol, or one that you think contains alcohol, replace it by a gasoline that you know does not contain alcohol.

3.Check the air cleaner. Check the air cleaner element to be sure it is clean and in good condition. Loosen the cover screw and remove the left side maintenance cover. Press the latch tab on the top of the air cleaner body, remove the air cleaner cover, check the element. Clean or replace the element if necessary.

CAUTION

Never run the engine without the air cleaner. Rapid engine wear will result from contaminants, such as dust and dirt, being drawn through the carburetor, into the engine.

CAUTION

If the engine stops and will not restart, check the engine oil level before

troubleshooting in other areas.

High altitude operation

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 and readjusting the pilot screws. If you always operate the generator at altitudes higher than 1,500m (5,000 feet) above sea level, have your authorized dealer perform these carburetor modifications. Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 305m (1,000 feet) increase in altitude. The affect 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.

CAUTION

6. GENERATOR USE

WARNING

To prevent electrical shock from faulty appliances, the generator should be grounded. Connect a length of heavy wire between the generator's ground 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 backfeed into the utility lines. Such backfeed may electrocute utility company workers or others who contact the lines during a power outage, and when utility power is restored, the generator may explode, burn, or cause fires in the building's electrical system.

CAUTION

Maximum power would be available for the first 30 minutes. For continuous operation, do not exceed the rated power.

Do not exceed the current limit specified for any one receptacle.

Do not connect the generator to a household circuit. This could cause the damage to the generator or to electrical appliances in the house.

Do not modify or use the generator for other purposes than it is intended for. Also observe the following when using the generator. A. Do not connect generators in parallel. B. Do not connect an extension to the exhaust pipe.

When an extension cable is required, be sure to use a tough rubber

sheathed flexible cable.( IEC245

Limit length of extension cables: less than 60 m for cables if 1.5 mm and

less than100m for cables of 2.5 mm .

Keep the generator away from other electric cables or wires such as

commercial power supply lines.

Electrical equipment (including electrical lines and plugs connection)

could not be defective.

CAUTION

Be sure that all appliances are in good working order before connecting them to the generator. If an appliance begins to operate abnormally, becomes sluggish, or stops suddenly, turn off the generator engine switch immediately. Then disconnect the appliance, and examine it for signs of malfunction.

3. In order to acquire both the best effect and the maximum service life of the generator. Usually, the new generator should run 20 hours under 50% load, the generator may reach the best performance.

Output and Overload Indicators

The output indicator light(green)will remain ON during normal operating conditions. If the generator is overloaded(in excess of 1.0kVA), or if there is a short in the connected appliance, the output indicator light(green) will go OFF, the overload indicator light(red) will go ON and current to the connected appliance will be shut off. Stop the engine if the overload indicator light (red) comes ON and investigate the overload source.

CAUTION

Before connecting an appliance to the generator, check that it is in good order, and that its electrical rating does not exceed that of the generator. Then connect the power cord of the appliance, and start the engine.

CAUTION

Indicator lights (both red and green) may come ON during generator starting. It is normal if the red indicator light goes off after 4 seconds, if not, please contact your dealer.

1. Connect the ground terminal.

2. Start each engine according to "STARTING THE ENGINE". When the output indicator light(green)does not light and the overload indicator

light (red) lights instead, set the engine switch to STOP, stop the engine at once and then start the engine again.

3. Confirm that the equipment to be used is switched off, and insert the plug

of the equipment to be used into the AC receptacle

Confirm that the use equipment to be connected is switched off. When the equipment to be used is switched on, it will operate suddenly, and injuries or accidents may be caused.

CAUTION

4. Switch on the equipment to be used. In case of overload operation or when trouble occurs for the equipment being used, the output indicator light(green) will go out, the overload indicator light(red) will light continuously, and no power will be put out. At this time, the engine will not stop, so that the engine must be stopped by setting the respective engine switch to STOP.

CAUTION

When equipment requiring a large starting power, like a motor etc., is used, the overload indicator light (red) and the output indicator light(green)may light together for a short time (about 4 sec), but this is no abnormality. After start of the equipment, the overload indicator light (red) will go out and the output indicator light(green) will stay lit.

Low oil alarm system

The Low oil alarm system is designed to prevent engine damage caused by an insufficient amount of oil in the crankcase. Before the oil level in the crankcase falls below a safe limit, the Low oil alarm system will automatically shut down the engine (the engine switch will remain in the ON position).

If the low oil alarm system shuts down the engine, the low oil alarm indicator light(red) will come on when you operate the starter, and the engine will not run. If this occurs, add engine oil.
