Operator Safety Equipment Description Read this manual carefully and become familiar with your generator. Know its applications, its limitations and any hazards involved. The generator is an engine–driven, revolving field, alternating current (AC) generator. It was designed to supply electrical power for operating compatible electrical lighting, appliances, tools and motor loads. The generator’s revolving field is driven at about 3,600 rpm by a single-cylinder engine.
DANGER Storage batteries give off explosive hydrogen gas during recharging. Hydrogen gas stays near battery for a long time after battery has been charged. Slightest spark will ignite hydrogen and cause explosion. You can be blinded or severely injured. Battery electrolyte fluid contains acid and is extremely caustic. Contact with battery fluid will cause severe chemical burns. • DO NOT allow any open flame, spark, heat, or lit cigarette during and for several minutes after charging a battery.
WARNING Generator produces hazardous voltage. Failure to isolate generator from power utility can result in death or injury to electric utility workers due to backfeed of electrical energy. • When using generator for backup power, notify utility company. Use approved transfer equipment to isolate generator from electric utility. • 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.
Assembly Add Engine Oil Your generator requires some assembly and is ready for use after it has been properly serviced with the recommended fuel and oil. If you have any problems with the assembly of your generator, please call the generator helpline at (877) 224-0458. If calling for assistance, please have the model, revision, and serial number from the data tag available. See Generator Controls and Features for data tag location. Unpack Generator 1. Set the carton on a rigid, flat surface. 2.
System Ground Generator Location The generator has a system ground that connects the generator frame components to the ground terminals on the AC output receptacles. The system ground is connected to the AC neutral wire (the neutral is bonded to the generator frame). Special Requirements There may be Federal or State Occupational Safety and Health Administration (OSHA) regulations, local codes, or ordinances that apply to the intended use of the generator.
Features and Controls Read this Operator’s Manual and safety rules before operating your generator. Compare the illustrations with your generator, to familiarize yourself with the locations of various controls and adjustments. Save this manual for future reference. A N M L B C K J D H E G F A - Fuel Tank — Capacity of 1.32 U.S. gallons (5.0 L). B - Circuit Breaker (AC) — A push-to-reset circuit breaker is provided to protect the receptacle and generator against electrical overload.
Cord Sets and Receptacles Use only high quality, well-insulated, grounded extension cords with the generator’s 120 Volt duplex receptacle. Inspect extension cords before each use. Check the ratings of all extension cords before you use them. Extension cord sets used should be rated for 125 Volt AC loads at 15 Amps or greater for most electrical devices. Some devices, however, may not require this type of extension cord. Check the operator’s manuals of those devices for the manufacturer’s recommendations.
Operation WARNING Starting the Engine Disconnect all electrical loads from the generator. Use the following start instructions: 1. Make sure unit is on a level surface. IMPORTANT: Failure to start and operate the unit on a level surface will cause the unit not to start or shut down during operation. 2. Turn fuel valve (A) to “Open” position (fully clockwise). A Contact with muffler area can result in serious burns. Exhaust heat/gases can ignite combustibles, structures or damage fuel tank causing a fire.
Charging a Battery Your generator has the capability of recharging a discharged 12 Volt automotive or utility style storage battery. DO NOT use the unit to charge any 6 Volt batteries. DO NOT use the unit to crank an engine having a discharged battery. DANGER Storage batteries give off explosive hydrogen gas during recharging. Hydrogen gas stays near battery for a long time after battery has been charged. Slightest spark will ignite hydrogen and cause explosion. You can be blinded or severely injured.
Creating a Temporary Shelter 1. In an emergency, use the original shipping carton. 2. Cut off top carton flaps and one long side of carton to expose muffler side of unit. If required, tape up other sides of carton to fit over generator as shown. Wind 6. Start generator as described in the section Starting the Engine, then place carton over generator. Keep at least 5 ft. (1.5 m) clearance on all sides of generator including overhead with shelter in place.
Don’t Overload Generator Capacity You must make sure your generator can supply enough rated (running) and surge (starting) watts for the items you will power at the same time. Follow these simple steps: 1. Select the items you will power at the same time. 2. Total the rated (running) watts of these items. This is the amount of power your generator must produce to keep your items running. See Wattage Reference Guide. 3. Estimate how many surge (starting) watts you will need.
Maintenance General Recommendations Regular maintenance will improve the performance and extend the life of the generator. See an authorized dealer for service. The generator’s warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the generator as instructed in this manual and the engine operator’s manual.
Storage The generator should be started at least once every seven days and allowed to run at least 30 minutes. If this cannot be done and you must store the unit for more than 30 days, use the following guidelines to prepare it for storage. Generator Storage • Clean the generator as outlined in Cleaning. • Check that cooling air slots and openings on generator are open and unobstructed. Long Term Storage Instructions Fuel can become stale when stored over 30 days.
Troubleshooting Problem Engine is running, but no AC output is available. Engine runs good at no-load but “bogs down” when loads are connected. Engine will not start; or starts and runs rough. Cause 1. 2. 3. 4. 1. Short circuit in a connected load. 2. Engine speed is too slow. 3. Generator is overloaded. Reset circuit breaker. Contact authorized service facility. Check and repair. Connect another device that is in good condition. 4. Shorted generator circuit. 1. 2. 3. 4. 5. 1. 2. 3. 4. 5.
