• Maintain Safe Distance: Keep a minimum of 5 feet (1.5m) from objects.
• Ground: Consult an electrician for grounding requirements.
• Carbon Monoxide (CO): Danger of poisonous gas.

DANGER: Generator exhaust contains high levels of carbon monoxide (CO), an invisible, odorless, and extremely poisonous gas. NEVER operate generators indoors. Doing so CAN KILL YOU IN MINUTES. Only operate generators outside, in a well-ventilated area, and direct exhaust away from occupied spaces. Install battery-powered carbon monoxide detectors in living areas.

DANGER: Fire and electrocution hazard. DO NOT connect to a building's electrical system unless properly installed with a transfer switch by a qualified electrician. Failure to do so can cause property damage and kill or injure utility workers.

DANGER: Electrocution hazard. NEVER use the generator in wet or damp locations. Protect from rain, snow, water spray, or standing water.

WARNING: Become familiar with all instructions, warnings, illustrations, and specifications. Failure to follow instructions may result in electric shock, fire, and/or carbon monoxide poisoning.

NOTICE: Install battery-powered carbon monoxide detectors in living areas.

IMPORTANT SAFETY INSTRUCTIONS:

• Only use generators outside and far away from windows, doors, and vents.
• NEVER use a generator in a home, garage, basement, attic, crawl space, or any other enclosed area.
• If feeling dizzy, weak, or sick, move to fresh air immediately.
• The National Electrical Code requires a transfer switch for connection to a building's electrical system.
• Never use the generator to power medical support equipment.
• Never expose the generator to rain, snow, water spray, or standing water.
• Do not let children or untrained individuals operate the generator.
• Keep children, bystanders, and pets at least 10 ft. away.
• Maintain at least five feet of clearance on all sides of the generator.
• Do not operate in areas with combustible or hazardous materials.
• Do not operate while barefoot, with wet hands or feet, or in wet conditions.
• Do not use when tired or under the influence of drugs, alcohol, or medication.
• Do not touch hot surfaces like the muffler or engine.
• Keep body parts away from moving parts.
• Do not connect worn or damaged electrical cords.
• Do not operate on an incline; always use a flat, stable surface.
• Inspect for damage before each use.
• For optimal performance, use between 23°F (-5°C) and 104°F (40°C).
• Inspect fluids (oil and gasoline) before starting.
• Do not remove the oil dipstick or fuel cap when the generator is running.
• Securely tighten the oil dipstick and fuel cap.
• Avoid skin contact with engine oil or gasoline.
• Replace damaged or worn items with recommended parts.

GROUNDING:

• WARNING: Failure to properly ground can result in electric shock.
• Only use grounded 3-prong extension cords, tools, and appliances, or double-insulated tools and appliances.
• The generator neutral is bonded to the frame. Consult a qualified electrician for grounding requirements for your intended use.

DISCONNECTING THE BONDED NEUTRAL: This should only be done under specific circumstances and requires consulting a qualified electrician. It involves removing a green/yellow bonded jumper wire.

SAFETY PRECAUTIONS FOR GASOLINE AND GASOLINE VAPOR:

• DANGER: Gasoline is highly explosive and flammable.
• WARNING: Never loosen or remove the fuel cap while the generator is running. Turn off and cool for at least five minutes before refueling. Loosen cap slowly.
• WARNING: In case of gasoline fire, ensure the engine/fuel control switch is OFF before attempting to extinguish.
• Handle gasoline with care; never use as a cleaning agent.
• Store gasoline away from heat and ignition sources.
• Always store gasoline in an approved container.
• Do not smoke when handling fuel.
• Wear eye protection while refueling.
• Clean spills immediately.
• Securely tighten the fuel cap after adding gasoline.
• Drain fuel before storing the unit.

LIQUID PETROLEUM GAS (LPG/PROPANE):

• WARNING: Fire and explosion hazard. Never use damaged gas containers, hoses, or cylinders. If you smell propane, close the cylinder valve immediately and check for leaks with soapy water. Do not smoke or use open flames when checking for leaks.
• CAUTION: Only use approved propane cylinders with an Overfilling Prevention Device (OPD) valve. Keep tanks vertical and away from heat sources. Turn off and disconnect the tank when transporting or storing.
• LPG/Propane is highly flammable and explosive.
• LPG/Propane can settle in low places as it is heavier than air.
• Always keep a propane cylinder upright.
• Prevent skin contact with LPG/propane.
• Keep the propane cylinder away from the generator exhaust.
• Be sure the generator and propane cylinder are on a flat surface before operating.
• If there is a propane odor, do not start the unit.
• When transporting, ensure the propane cylinder and hose are not attached.
• Store propane cylinders away from ignition sources.

LEAK TESTING: Brush connections with a soapy solution. If bubbles form, there is a leak. Contact customer service if leaks persist.

IMPORTANT INFORMATION FOR THE CO SENSOR:

• The CO Sensor monitors for carbon monoxide and automatically shuts down the engine if dangerous levels are detected.
• It can also detect CO from other fuel-burning sources.
• If the generator shuts down and the RED indicator light flashes, leave the area immediately and move the generator to a safe, open area.
• The CO Sensor does NOT replace home carbon monoxide alarms.

UNDERSTANDING THE CO SENSOR INDICATOR LIGHTS:

• RED: Unsafe levels of carbon monoxide accumulated. The light flashes after shut-off. Move generator to a safe area and restart once the light is off.
• YELLOW: CO sensor system fault. Generator shuts down. Contact an authorized Westinghouse service center for diagnosis and repair.

SAFETY LABELS AND DECALS: Refer to the manual for descriptions of various safety labels including Action Label, Carbon Monoxide warnings, California Proposition 65, Pinch Point Hazard, Adding Oil, Hot Surface, Fuel Capacity, Engine Displacement, and Danger/Caution labels.

Electrical

GENERATOR CAPACITY:

• Do not overload the generator. Exceeding wattage/amperage capacity can damage the generator and connected devices.
• Calculate total running (continuous) watts and peak (starting) watts for all devices to be powered.
• Add the peak wattage of the largest device to the total running watts to determine the generator's peak wattage requirement.

MANAGING GENERATOR POWER:

• Disconnect all loads before starting the generator.
• Add loads sequentially, starting with the largest device.
• Allow generator output to stabilize between adding loads.

EXTENSION CORDS:

• WARNING: Extension cords running directly into the home increase the risk of carbon monoxide poisoning. Always use battery-powered carbon monoxide detectors.
• WARNING: Never use worn or damaged extension cords.
• Use grounded 3-prong or double-insulated cords, tools, and appliances.
• Ensure tools/appliances are in good working order.
• Ensure the electrical rating of the tool/appliance does not exceed the generator's capacity.
• NOTICE: Do not exceed wattage and/or amperage capacity.
