The generator is a potential source of electrical shock if misused. Do not expose the generator to moisture, rain or snow. Do not let the generator get wet, and do not operate it with wet hands.
These labels warn you of potential hazards that can cause serious injury. Read them carefully.
SAFETY INFORMATION
Read and understand this instruction manual before operating your generator. You can help prevent accidents by being familiar with your generator's controls, and by observing safe operating procedures.
Operator Responsibility Know how to stop the generator quickly in case of emergency. Understand the use of all generator controls, output receptacles, and connections. Do not let children operate the generator without parental supervision.
Carbon Monoxide Hazards Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing exhaust can cause loss of consciousness and may lead to death. If you run the generator in an area that is confined, or even partially enclosed, the air you breathe could contain a dangerous amount of exhaust gas. To keep exhaust gas from accumulating, provide adequate ventilation.
Electric Shock Hazards The generator produces enough electric power to cause a serious shock or electrocution if misused. Using a generator or electrical appliance in wet conditions, such as rain or snow, or near a pool or sprinkler system, or when your hands are wet, could result in electrocution. Keep the generator dry. If the generator is stored outdoors, unprotected from the weather, check all of the electrical components on the control panel, before each use. Moisture or ice can cause a malfunction or short circuit in electrical components, which could result in electrocution. Do not connect to a building electrical system unless a qualified electrician has installed an isolation switch.
Fire and Burn Hazards The exhaust system gets hot enough to ignite some materials. Keep the generator at least 3 feet (1 meter) away from buildings and other equipment during operation. Do not enclose the generator in any structure. Keep flammable materials away from the generator. 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. Let the engine cool before storing the generator indoors.
Gasoline is extremely flammable and is explosive under certain conditions. Do not smoke or allow flames or sparks where the generator is refueled or where gasoline is stored. Refuel in a well-ventilated area with the engine stopped.
Fuel vapors are extremely flammable and may ignite after the engine has started. Make sure that any spilled fuel has been wiped up before starting the generator.

system should not take the place of checking the oil level before each use. If the engine stops and will not restart, check the engine oil level before troubleshooting in other areas. AC Circuit Breaker The AC circuit breaker will automatically switch OFF if there is a short circuit or a significant overload of the generator at the receptacle. If the AC circuit breaker is switched OFF automatically, check that the appliance is working properly and does not exceed the rated load capacity of the circuit before switching the AC circuit breaker ON again. The AC circuit breaker may be used to switch the generator power ON or OFF.
PRE-OPERATION CHECK
Engine Oil Engine oil is a major factor affecting engine performance and 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 SJ.
Always check the API SERVICE label on the oil container to be sure it includes the letter SJ. SAE 10W-30 is recommended for general, all-temperature use. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range.
1 Remove the oil filler cap and wipe the dipstick clean. 2 Check the oil level by inserting the dipstick into the filler neck without screwing it in. 3 If the level is low, fill to the top of the oil filler neck with the recommended oil. Fuel Check the fuel gauge, and refill the tank if the fuel level is low. Refuel carefully to avoid spilling fuel. Do not fill above the shoulder of the fuel strainer.
Gasoline is highly flammable and explosive, and you can be burned or seriously injured when refueling.
Stop engine and keep heat, sparks, and flame away. Refuel only outdoors. Wipe up spills immediately.
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.
STARTING THE ENGINE / STOPPING THE ENGINE
Starting the Engine 1 Make sure that the AC circuit breaker is in the OFF position. The generator may be hard to start if a load is connected. 2 Turn the fuel valve lever to the ON position. 3 The choke will be closed if the engine is cold, pull the choke rod out to the CLOSED position. 4 Turn the engine switch to the START position 5 Pull the starter grip lightly until resistance is felt, then pull briskly.
Operating the starter motor for more than 5 seconds can damage the motor. If the engine fails to start, release the switch and wait 10 seconds before operating the starter again. If the speed of the starter motor drops after a period of time, it is an indication that the battery should be recharged. When the engine starts, allow the engine switch to return to the ON position. If you have closed the choke, push it to the OPEN position as the engine warms up.
Stopping the Engine In an emergency: To stop the engine in an emergency, move the engine switch to the OFF position. In normal use:
1 Turn the AC circuit breaker to the OFF position. Disconnect DC battery charging cables. 2 Turn the engine switch to the OFF position. 3 Turn the fuel valve lever to the OFF position.
OPERATING INSTRUCTIONS
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. A transfer switch, which isolates generator power from utility power, is prerequisite.
Improper connections to a building electrical system 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 the generator may explode, burn, or cause fires when utility power is restored. Consult the utility company or a qualified electrician.
Ground System The 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. 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.
Substantial overloading will open the circuit breaker. Exceeding the time limit for maximum power operation or slightly overloading the generator may not switch the circuit breaker or circuit protector OFF, but will shorten the service life of the generator.
AC Operation 1 Start the engine . 2 Switch the AC circuit breaker ON. 3 Plug in the appliance.
Most motorized appliances require more than their rated power for startup. Do not exceed the current limit specified for any one receptacle. If an overloaded circuit causes the AC circuit breaker or AC circuit protector to switch OFF, reduce the electricalload on the circuit, wait a few minutes and then reset the AC circuit breaker or AC circuit protector.
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 dealer perform this carburetor modification. This engine, when operated at high altitude with the carburetor modifications for 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 effect of altitude on horsepower will be greater than this if no carburetor modification is made.
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.
MAINTENANCE
The Importance of Maintenance. Good maintenance is essential for safe, economical, and trouble-free operation. It will also help reduce air pollution.
Improper maintenance, or failure to correct a problem before operation, can cause a malfunction in which you can be seriously injured or killed. Always follow the inspection and maintenance recommendations and schedules in this instruction manual.
Maintenance Safety Make sure the engine is off before you begin any maintenance or repairs. Let the engine and exhaust system cool before touching. 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.
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.

Engine Oil Change
Drain the oil while the engine is warm to assure rapid and complete draining.
1 Remove the drain plug and sealing washer, remove the oil filler cap, and drain the oil. 2 Reinstall the drain plug and sealing washer. Tighten the plug securely. 3 Refill with the recommended oil and check the oil level. Wash your hands with soap and water after handling used oil.
Air Cleaner Service A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor malfunction, service
the air cleaner regularly. Service more frequently when operating the generator in extremely dusty areas.
Never run the generator without the air filter. Rapid engine wear will result. 1 Unsnap the air cleaner cover clips, remove the air cleaner cover, and remove the element. 2 Wash the air cleaner element in a solution of household detergent and warm water, then rinse thoroughly, or wash in nonflammable or high flashpoint solvent. Allow the air cleaner element to dry thoroughly. 3 Soak the air cleaner element in clean engine oil and squeeze out the excess oil. The engine will smoke during initial startup if too much oil is left in the air cleaner element. 4 Reinstall the air cleaner element and the cover.
Fuel Sediment Cup Cleaning The sediment cup prevents dirt or water, which may be in the fuel tank from entering the carburetor. If the engine has not been running for a long time, the sediment cup should be cleaned.
1 Turn the fuel valve lever to the OFF position. Remove the sediment cup, O-ring, and filter.
2 Clean the sediment cup, O-ring, and filter in nonflammable or high flash point solvent.
3 Reinstall the filter, O-ring, and sediment c up. 4 Turn the fuel valve lever ON and check for leaks.
Spark Plug Service To ensure proper engine operation, the spark plug must be properly gapped and free of deposits. If the engine has been running, the muffler will be very hot. Be careful not to touch the muffler.
1 Remove the spark plug cap. 2 Clean any dirt from around the spark plug base. 3 Use a spark plug wrench to remove the spark plug. 4 Visually inspect the spark plug. Discard it if the insulator is cracked, chipped or fouled. 5 Measure the plug gap with a feeler gauge. Correct as necessary by carefully bending the side
electrode.
The gap should be: 0.028 0.031 in (0.70 0.80 mm) 6 Check that the spark plug washer is in good condition, and thread the spark plug in by hand to prevent cross-threading. 7 After the spark plug is seated, tighten with a spark plug wrench to compress the washer.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats to compress the washer. If reinstalling a used spark plug, tighten 1/8 1/4 turn after the spark plug seats to compress the
washer.
The spark plug must be securely tightened. An improperly tightened spark plug can become very hot and could damage the engine. Never use spark plugs which have an improper heat range.
Spark Arrester Maintenance If the generator has been running, the muffler will be very hot. Allow it to cool before proceeding.
The spark arrester must be serviced every 100 hours to maintain its efficiency. Clean the spark arrester as follows:
1. Loosen the screw by the exhaust port of the muffler and remove the spark arrester. 2. Use a brush to remove carbon deposits from the spark arrester screen.
Inspect the screen for breaks or tears and replace it if necessary. 3. Install the spark arrester in the reverse order of removal.
