Know its applications, its limitations and any hazards involved. The generator is an engine­driven, 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. The manufacturer cannot possibly anticipate every possible circumstance that might involve a hazard. The warnings in this manual, and the tags and decals affixed to the unit are, therefore, not all-inclusive. If you use a procedure, work method or operating technique that the manufacturer does not specifically recommend, you must satisfy yourself that it is safe for you and others. You must also make sure that the procedure, work method or operating technique that you choose does not render the generator unsafe. Hazard Symbols and Meanings NOTICE Exceeding generators wattage/amperage capacity can damage generator and/or electrical devices connected to it. · DO NOT exceed the generator’s wattage/amperage capacity. See Don’t Overload Generator in the Operation section. A B C Every effort has been made to ensure that the information in this manual is both accurate and current. However, the manufacturer reserves the right to change, alter or otherwise improve the generator and this documentation at any time without prior notice. The Emission Control System for this generator is warranted for standards set by the Environmental Protection Agency and the California Air Resources Board. D E F G H J Safety Rules This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death. The safety alert symbol ( ) is used with a signal word (DANGER, WARNING, CAUTION), a pictorial and/or a safety message to alert you to hazards. DANGER indicates a hazard which, if not avoided, will result in death or serious injury. WARNING indicates a hazard which, if not avoided, could result in death or serious injury. CAUTION indicates a hazard which, if not avoided, might result in minor or moderate injury. NOTICE indicates a situation that could result in equipment damage.

A – Explosion B – Fire C – Electric Shock D – Toxic Fumes E – Kickback F – Hot Surface G – Flying Objects H – Moving Parts J – Read Manual 4 www.usa.husqvarna.com 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. · Wear protective goggles, rubber apron, and rubber gloves. WARNING Fuel and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. WHEN ADDING OR DRAINING FUEL · Turn generator OFF and let it cool at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank. · Fill or drain fuel tank outdoors. · DO NOT overfill tank. Allow space for fuel expansion. · If fuel spills, wait until it evaporates before starting engine. · Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources. · DO NOT light a cigarette or smoke. WHEN STARTING EQUIPMENT · Ensure spark plug, muffler, fuel cap, and air cleaner are in place. · DO NOT crank engine with spark plug removed. WHEN OPERATING EQUIPMENT · DO NOT tip engine or equipment at angle which causes fuel to spill. · This generator is not for use in mobile equipment or marine applications. WHEN TRANSPORTING OR REPAIRING EQUIPMENT · Transport/repair with fuel tank EMPTY or with fuel shutoff valve OFF. · Disconnect spark plug wire. WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK · Store away from furnaces, stoves, water heaters, clothes dryers, or other appliances that have pilot light or other ignition source because they can ignite fuel vapors. WARNING Running engine gives off carbon monoxide, an odorless, colorless, poison gas. Breathing carbon monoxide can cause headache, fatigue, dizziness, vomiting, confusion, seizures, nausea, fainting or death. · Operate generator ONLY outdoors. · Install a battery operated carbon monoxide alarm near the bedrooms. · Keep exhaust gas from entering a confined area through windows, doors, ventilation intakes, or other openings. · DO NOT start or run engine indoors or in an enclosed area, (even if windows and doors are open), including the generator compartment of a recreational vehicle (RV). WARNING · This generator does not meet U. S. Coast Guard Regulation 33CFR-183 and should not be used on marine applications. · Failure to use the appropriate U. S. Coast Guard approved generator could result in death or serious injury and/or property damage. WARNING Starter cord kickback (rapid retraction) can result in bodily injury. Kickback will pull hand and arm toward engine faster than you can let go. Broken bones, fractures, bruises, or sprains could result. · When starting engine, pull cord slowly until resistance is felt and then pull rapidly to avoid kickback. · NEVER start or stop engine with electrical devices plugged in and turned on. WARNING The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. 5 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. · DO NOT use generator with electrical cords which are worn, frayed, bare or otherwise damaged. · DO NOT operate generator in the rain or wet weather. · DO NOT handle generator or electrical cords while standing in water, while barefoot, or while hands or feet are wet. · DO NOT allow unqualified persons or children to operate or service generator. WARNING Starter and other rotating parts can entangle hands, hair, clothing, or accessories. · NEVER operate generator without protective housing or covers. · DO NOT wear loose clothing, jewelry or anything that may be caught in the starter or other rotating parts. · Tie up long hair and remove jewelry. CAUTION Excessively high operating speeds increase risk of injury and damage to generator. Excessively low speeds impose a heavy load. · DO NOT tamper with governed speed. Generator supplies correct rated frequency and voltage when running at governed speed. · DO NOT modify generator in any way. 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. · Code of Federal Regulation (CFR) Title 36 Parks, Forests, and Public Property require equipment powered by an internal combustion engine to have a spark arrester, maintained in effective working order, complying to USDA Forest service standard 5100-1C or later revision. In the State of California a spark arrester is required under section 4442 of the California Public resources code. Other states may have similar laws. NOTICE Exceeding generators wattage/amperage capacity can damage generator and/or electrical devices connected to it. · DO NOT exceed the generator’s wattage/amperage capacity. See Don’t Overload Generator in the Operation section. · Start generator and let engine stabilize before connecting electrical loads. · Connect electrical loads in OFF position, then turn ON for operation. · Turn electrical loads OFF and disconnect from generator before stopping generator. NOTICE Improper treatment of generator can damage it and shorten its life. · Use generator only for intended uses. · If you have questions about intended use, ask dealer or contact local service center. · Operate generator only on level surfaces. · DO NOT expose gene …..
