RECOGNIZE SAFETY SYMBOLS, WORDS AND LABELS What You Need to Know About Safety Instructions Warning and Important Safety Instructions appearing in this manual are not meant to cover all possible conditions and situations that may occur. Common sense, caution and care must be exercised when operating or cleaning tools and equipment. Always contact your dealer, distributor, service agent or manufacturer about problems or conditions you do not understand. This is the safety alert symbol.
Notice Regarding Emissions: Engines certified to comply with U.S. EPA emission regulations for SORE (Small Off Road Equipment) are certified to operate on regular unleaded gasoline and may include the following emission control systems: Three-Way Catalyst (TWC) (if equipped), and Engine Modifications (EM). Legal Requirements: Federal and/or State Occupational Safety and Health Administration (OSHA) regulations, local codes, and/or ordinances may apply to the intended use of this generator.
Powerful Voltage: This generator produces powerful voltage, which can result in electrocution. • ALWAYS ground this generator before using it. (See “Ground the Generator” section in this manual). • Only electrical devices should be plugged into this generator, either directly or with an extension cord. NEVER connect a building electrical system to this generator without a qualified electrician. Doing so voids your warranty.

GENERATOR COMPONENTS Observe the locations and functions of the various components and controls of this generator.
PREPARING THE GENERATOR FOR USE Using this Generator for the First-Time STOP! The following section describes the required steps for preparing this generator for the first use. Failure to correctly perform these steps can damage this generator and/or shorten its life. If still unsure about how to perform any of these steps after reading this section, call 1-866-460-9436 Monday - Friday, 8 AM - 4 PM Central Time for customer service.
Step 2 - Add Gasoline Gasoline and gasoline fumes are highly flammable and explosive. Handling fuel can result in serious injury or burns. • Do not fill the fuel tank near a heat, sparks or an open flame. Keep gasoline away from appliance pilot lights, barbecues, electric appliances, power tools, etc. • Do not overfill the fuel tank. Always check for fuel spills and immediately wipe them up. Spilled fuel is a fire hazard and causes environmental damage.
Step 3 - Ground the Generator Failure to properly ground this generator can result in electrocution. Ground this generator by tightening the grounding nut against a grounding wire as illustrated in Figure 3. A No. 12 AWG (American Wire Gauge) stranded copper wire is generally an acceptable grounding wire. The other end of this grounding wire should be connected to a copper or brass grounding rod that is driven into the earth. Grounding codes can vary by location.
Gasoline and gasoline fumes are highly flammable and explosive. Handling fuel can result in serious injury or burns. • Do not fill the fuel tank near a heat, sparks or an open flame. Keep gasoline away from appliance pilot lights, barbecues, electric appliances, power tools, etc. • Always allow several minutes for the engine to cool before refueling. • Do not overfill the fuel tank. Always check for fuel spills and immediately wipe them up. Spilled fuel is a fire hazard and causes environmental damage.
Fuel Cock The fuel cock is located between the fuel tank and carburetor. When the fuel cock is in the ON position, fuel is allowed to flow from the fuel tank to the carburetor. Be sure to return the fuel cock to the OFF position after stopping the engine. Choke Rod The choke is used to provide an enriched fuel mixture when starting a cold engine. It can be opened and closed by operating the choke rod manually.
A device's rated (running) wattage should be listed somewhere on the device itself and/or in its manual. If the wattage specification for a device is not available, the wattage can be calculated by multiplying the Voltage requirement (120) by the Amperage drawn. Watts = Volts x Amperes Or, the wattage required by a device can be estimated by using the following chart. The chart provides only estimates and it is better to know the exact wattage of each electrical device to be powered by this generator.
SOME NOTES ABOUT POWER CORDS Long or thin cords can require more wattage from a generator to power an electrical device. Figure 6 shows the recommended cords according to the power requirement of the electrical device. When using cords that exceed these specifications, allow for the electrical device to have a slightly higher rated wattage requirement. Recommend that you use high quality, UL-rated, well-insulated grounded extension cords that are intended for outdoor use.
STOPPING THE GENERATOR To stop this generator: 1. Turn off all connected electrical devices and then unplug them. 2. Allow this generator to run for several more minutes with no electrical devices connected to help stabilize the temperature of this generator. 3. Turn the fuel valve to the “OFF” position. 4. Set the engine power switch to the “OFF” position. Allow this generator to cool down before touching areas that become hot during operation.
Checking the Oil Level It is important to check the oil level in the engine crankcase before each use to ensure that there is a sufficient quantity. To check the oil level: 1. Verify that this generator is shut down and on a level surface. 2. Unscrew the oil filler/dipstick cap from the engine. 3. With a dry cloth, wipe the oil off of the dipstick that is located on the inside of the cap. 4. Insert the dipstick as if replacing the cap and then remove again. There should be oil on the dipstick.
Air Filter Maintenance Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally verify that the air filter is free of excessive dirt. The air filter will require more frequent cleaning when operating this generator in extremely dusty areas. To clean the air filter, remove the foam filter element from the generator and wash it in warm water and household dish detergent. Thoroughly rinse and dry.
STORAGE/TRANSPORT PROCEDURES Do not store gasoline for more than 3 months. Never place any type of storage cover on this generator while it is still hot. When transporting or storing this generator for extended time: • Allow generator to fully cool before moving it. A hot engine and exhaust system can burn you and ignite some materials. • Empty the fuel tank. (See “Emptying the Fuel Tank” in the “Maintenance/Care” section.) • Turn the fuel valve to the “off” position. • Disconnect the spark plug.
TROUBLESHOOTING IMPORTANT: If trouble persists, call our customer help line at 1-866-460-9436, Monday - Friday, 8 AM - 4 PM Central Time. Symptom Engine will not start.
