Before Starting  
System Ground  
You must connect the ground wire to a metal stake, spike or screw in the  
earth before using the generator.  
WARNING  
Improper connections to a building's electrical system can allow  
electrical current from the generator to backfeed into utility lines.  
This backfeed may electrocute utility company workers or others  
who contact the lines during a power outage. Consult the utility  
company or a qualified electrician.  
Follow any federal or state Occupational Safety and Health Administration  
(OSHA) regulations, local codes or ordinances that apply to the intended  
use of the generator. Consult a qualified electrician, electrical inspector or  
the local agency having jurisdiction.  
In some areas, you must register your generator with local utility companies.  
Generators used at construction sites may have additional regulations.  
CAUTION  
Fuel/Oil Mix  
Improper connections to a building's electrical system can allow  
electrical current from the utility company to backfeed into the  
generator. When utility power is restored, the generator may explode,  
burn or cause fires in the building's electrical system.  
Do not operate this generator using gasoline alone or the engine will  
overheat! Use a fuel/oil mix of 50 to 1. The oil must be 2-stroke oil.  
Make sure to pour the fuel/oil mix through the fuel tank filter to keep  
solid material out of the fuel tank. Do not fill the fuel tank above the  
fuel filter top. Shake the fuel tank before starting. Avoid repeated or  
prolonged contact with skin or breathing of fuel vapor.  
Use a ground fault circuit interrupter (GFCI) in any damp or highly  
conductive area, such as metal decking or steel work. Do not touch  
bare wires or receptacles. Do not use the generator with electrical cords  
that are worn, frayed, bare or damaged in any way. Do not operate the  
generator in the rain. Do not handle the generator or electrical cords  
while standing in water, while barefoot or while hands or feet are wet.  
Do not allow children or unqualified people to operate the generator.  
WARNING  
Gasoline and its vapors are extremely flammable and can be  
explosive in certain conditions. Fire or explosion can cause severe  
burns or death.  
If the engine has been running, allow it to cool before adding any fuel/oil  
mix. Refill the tank outdoors. Remove the gas cap slowly to relieve any  
pressure inside the tank. Keep sparks, flames, heat and other ignition  
sources away while adding or storing oil and fuel. Do not light a cigarette  
or smoke when refueling. Wipe up any fuel spills.

Operation Guidelines  
CAUTION  
CAUTION  
Do not allow the starter cord to snap back. Return it slowly by hand.  
Exceeding the generator's wattage/amperage capacity may damage  
the generator and electrical devices connected to it.  
5. Move the choke lever back to the "open" position after the engine  
warms up.  
Do not connect any electrical loads before starting the engine and  
allowing it to warm up. Make sure electrical devices are "off" when  
you do connect them.  
High-Altitude Operation  
The standard carburetor air-fuel mixture will be too rich at high altitude  
(5,000 feet or 1,500 m and above), decreasing performance and increasing  
fuel consumption.  
Starting the Engine  
1. Place the generator on a level surface.  
2. Turn the fuel valve to the "on" position.

Take care when adding electrical loads to the generator. Never connect any  
load to the generator before starting the engine. The safe way to manage  
generator power is to sequentially add loads:  
Stopping the Engine  
Turn off all attached appliances and tools and unplug their cords. Move the  
AC switch, then the engine switch and finally the fuel lever to "off" positions.  
Transport  
1. Start the engine and allow it to warm up.  
Make sure the engine switch and fuel lever are in the "off" positions.  
Keep the generator level to prevent fuel spillage. Fuel vapor or spillage  
may ignite.  
2. Plug in the first load (turned off), which is preferably the largest load.  
3. Let the generator output stabilize (engine runs smoothly and device  
operates correctly).  
4. Plug in and turn on the next load.  
5. Let the generator stabilize again.  
WARNING  
Repeat steps 4 and 5 for each additional load.  
Contact with a hot engine or exhaust system can cause serious  
burns or fires. Let the engine cool before transporting the generator.  
If an appliance begins to operate abnormally, becomes sluggish  
or stops suddenly, then turn it off and disconnect it.  
Take care not to drop or strike the generator while transporting. Do not  
place heavy objects on the generator.  
Never operate a damaged or defective motor! When adjusting or making  
repairs to your generator disconnect the spark plug wire from the spark  
plug and place that wire where it cannot contact the spark plug. Do not  
use a garden hose to clean the generator because water can enter the fuel  
system and cause problems.  
ATTENTION  
Heavy overloading will trip the circuit breaker.  
Slight overloading may not trip the circuit breaker  
but will shorten the life of the generator.

*Wattages listed are for reference only. Check the appliance or tool for  
the actual wattage.  
6. Thread the spark plug back in by hand to prevent cross-threading.  
The correct torque to use is 14 ft-lbs (20 Nm).  
If the load exceeds the rated capacity of the generator, then the AC  
protector will trip, stopping the electricity flow to connected devices.  
Reduce the load to within the rated capacity and press the reset  
button to use the generator again.  
ATTENTION  
The spark plug must be securely tightened. An improperly tightened  
spark plug can become very hot and could damage the engine.

Air Filter Cleaning  
3. Pour a small amount of oil (foam-air-filter or SAW #20 motor oil  
recommended) into the filter element and gently squeeze out excess oil.  
Never wring out the filter element, as it may tear. The generator will  
smoke if too much oil remains in the filter element.  
A dirty air filter will restrict airflow to the carburetor. Service the air filter  
regularly to prevent carburetor malfunction (service more frequently in  
extremely dusty areas).  
4. Reinstall the filter element and air filter cover. Be sure both  
projections of the air filter cover fit the control box slots before  
tightening the mount screws.  
1. Unscrew the air filter cover.
