Operator Safety Hazard Symbols and Meanings 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.
WARNING The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. 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.
WARNING Contact with muffler area can result in serious burns. Exhaust heat/gases can ignite combustibles, structures or damage fuel tank causing a fire. • DO NOT touch hot parts and AVOID hot exhaust gases. • Allow equipment to cool before touching. • Keep at least 5 feet (1.5 m) of clearance on all sides of generator including overhead.
Assembly Install the wheel kit as follows: 1. Tip generator so that generator rests on frame with engine end up. 2. Slide axle (A) through both mounting brackets. 3. Slide a wheel (B) over the axle. NOTE: Be sure to install both wheels with the air pressure valve on the outboard side. 4. Place a washer (C) on axle and then place an e-ring (D) in axle groove. Your generator requires some assembly and is ready for use after it has been properly serviced with the recommended fuel and oil.
Add Engine Oil 1. Place generator on a flat, level surface. 2. Clean area around oil fill and remove yellow oil fill cap. NOTE: See Oil in Engine Maintenance to review oil recommendations. Verify provided oil bottle is correct viscosity for current ambient temperature. 3. Using oil funnel (optional), slowly pour contents of provided oil bottle into oil fill opening until oil level reaches the “Full” mark on the dipstick. NOTICE Improper treatment of generator can damage it and shorten its life.
Attach Negative Battery Cable System Ground Your unit is equipped with electric start capability but can be started manually. If you choose not to use the electric start feature, you do not need to connect the negative battery cable. The sealed battery on the generator pre–installed except for the negative (black) battery cable. The generator has a system ground that connects the generator frame components to the ground terminals on the AC output receptacles.
Generator Location Clearances and Air Movement WARNING Exhaust heat/gases can ignite combustibles, structures or damage fuel tank causing a fire. • Keep at least 5 ft. (1.5 m) clearance on all sides of generator including overhead. Place generator outdoors in an area that will not accumulate deadly exhaust gas. DO NOT place generator where exhaust gas (A) could accumulate and enter inside or be drawn into a potentially occupied building.
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. K J H A B C D G E F A - 120 Volt AC, 20 Amp, Duplex Receptacles — May be used to supply electrical power for the operation of 120 Volt AC, 20 Amp, single phase, 60 Hz electrical, lighting, appliance, tool, and motor loads.
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 20 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.
Battery Float Charger Use battery float charger jack to keep the starting battery charged and ready for use. Battery charging should be done in a dry location, such as inside a garage. 1. Plug charger into unit’s “Battery Float Charger” jack, which is located next to the start switch. Plug battery charger into a 120 Volt AC wall receptacle. 2. Unplug charger from unit and wall outlet when generator is being started and while it is in operation. 3.
Operation Starting the Engine IMPORTANT: Always unplug the battery float charger before starting the generator. 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 the fuel valve to the “On” position. The fuel valve handle should be vertical (pointing toward the ground) for fuel to flow. 3.
Connecting Electrical Loads 1. Let engine stabilize and warm up for a few minutes after starting. 2. Plug in and turn on the desired 120 and/or 240 Volt AC, single phase, 60 Hz electrical loads. NOTE: • DO NOT connect 240 Volt loads to the 120 Volt duplex receptacles. • DO NOT connect 3-phase loads to the generator. • DO NOT connect 50 Hz loads to the generator. • DO NOT OVERLOAD THE GENERATOR. See Don’t Overload Generator.
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 Maintenance Schedule Follow the hourly or calendar intervals, whichever occurs first. More frequent service is required when operating in adverse conditions noted below.
NOTICE Improper treatment of generator can damage it and shorten its life. • DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors. • DO NOT insert any objects through cooling slots. • Use a soft bristle brush to loosen caked on dirt or oil. • Use a vacuum cleaner to pick up loose dirt and debris. Battery Maintenance Other than float charging, described elsewhere, no maintenance is required for the starting battery. Keep the battery and terminals clean and dry.
Changing Engine Oil Change the oil after the first 5 hours of operation. Change oil every 50 hours thereafter. If you are using your generator under extremely dirty or dusty conditions, or in extremely hot weather, change the oil more often. To service the air cleaner, follow these steps: 1. Loosen screws (A) and remove air cleaner cover (B). D CAUTION Avoid prolonged or repeated skin contact with used motor oil. • Used motor oil has been shown to cause skin cancer in certain laboratory animals.
4. Replace spark plug if electrodes are pitted, burned or porcelain is cracked. Use the recommended replacement spark plug. See Specifications. 5. Install spark plug and tighten firmly. Service Spark Arrester The engine exhaust muffler has a spark arrester screen. Inspect and clean the screen every 100 hours of operation or once each year, whichever comes first. If you use your generator on any forest-covered, brushcovered, or grass-covered unimproved land, it must have a spark arrester.
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.
