Before using the ground terminal, consult a qualified electrician, electrical inspector, or local agency having jurisdiction for local codes or ordinances that apply to the intended use of the generator.

SAFETY PRECAUTIONS FOR GASOLINE AND GASOLINE VAPOR
DANGER
Fire and explosion hazard. Gasoline is highly explosive and flammable and can cause severe burns or death.
WARNING
Fire and Burn Hazard. NEVER loosen or remove the fuel cap while the generator is running. Turn the unit off and allow it to cool for at least five minutes before adding gasoline. Loosen the fuel cap slowly.
WARNING
In case of a gasoline fire, do not attempt to extinguish the flame unless the engine/fuel control switch is in the OFF position. Introducing an extinguisher to a generator with an open fuel switch could create an explosion hazard.

• Fire Hazard. Gasoline is highly flammable. Handle with care.

• Never use gasoline as a cleaning agent.

• Gasoline is a skin irritant and needs to be cleaned up immediately if it comes in contact with the skin.

• Do not store gasoline near furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions.

• Keep gasoline away from sparks, open flames, pilot lights, heat, and other sources of ignition.

• Store any containers containing gasoline in a well-ventilated area, away from any combustibles or source of ignition.

• ALWAYS store gasoline in a container approved for gasoline. Unapproved containers can break or deteriorate allowing gasoline or gasoline vapors to escape which can create a serious hazard.

• Gasoline has a distinctive odor, this will help detect potential leaks quickly.

• Gas vapors can cause a fire if ignited.

• Do not smoke when handling fuel, adding fuel to the generator, or emptying the gas tank. A – Ground Terminal

• Wear eye protection while refueling.

• Before adding fuel to the generator, turn the unit off and allow it to cool a minimum of five minutes. If necessary, move the unit to level ground.

• Do not remove the fuel tank cap when the generator is running.

• Loosen the fuel cap slowly to safely release pressure, keep gasoline from escaping around the cap, and to avoid the heat from the muffler igniting fuel vapors.

• NEVER fill the generator’s gasoline tank beyond the maximum fill ring on the fuel screen. Keeping gasoline levels at or below the fill ring will allow for fuel expansion.
  Overfilling the fuel tank can result in a sudden overflow of gasoline and result in spilled gasoline coming in contact with HOT surfaces.

• Spilled fuel can ignite. Wipe up spills immediately and allow area to dry before operating the generator. NEVER attempt to burn off spilled fuel.

• Securely tighten the fuel cap after adding gasoline.

• Do not cover the fuel cap while the generator is in oper- ation. Covering the cap may cause the engine to fail or damage the product.

• Drain fuel before storing the unit. Store the unit and the fuel separately in well-ventilated areas away from sparks, open flames, pilot lights, heat, and other sources of ignition.

• Turn the unit off and allow it to cool a minimum of 30 minutes before draining fuel.

IMPORTANT INFORMATION FOR THE CO SENSOR
The CO Sensor monitors for the accumulation of poisonous carbon monoxide gas around the generator when the engine is running. If increasing levels of CO gas are detected, the CO Sensor automatically shuts down the engine.
The CO Sensor will also detect the accumulation of carbon monoxide from other fuel burning sources used in the area of operation. For example, if the exhaust of fuel burning tools is pointed at a CO Sensor-equipped generator, a shut-off may be initiated due to rising CO levels. This is not an error.
Hazardous carbon monoxide has been detected. Move and redirect any additional fuel burning sources to dissipate carbon monoxide away from personnel and occupied buildings.
NOTE: Remote start-equipped generators must be restarted with the START/STOP button on the control panel after an automatic shut-down occurs.
Generators are intended to be used outdoors, far from occupied buildings and the exhaust pointed away from personnel and buildings. If misused and operated in a location that results in the accumulation of CO, like in a partially enclosed area, the CO Sensor shuts off the engine and the RED indicator light will flash notifiying the user that there are unsafe levels of carbon monoxide.
If the generator shuts off and the RED indicator light flashes, leave the area immediately. Wait for the carbon monoxide to dissipate and the RED indicator light to turn off before returning to the affected area. Once it is safe to return, read the Action Label for further steps to take. The CO Sensor DOES NOT replace carbon monoxide alarms. Install battery-powered carbon monoxide alarm(s) in your home.
WARNING
Automatic shutoff accompanied with a flashing RED light in the CO Sensor portion of the control panel is an indication that the generator was improperly located which allowed carbon monoxide to accumulate to unsafe levels. If you start to feel sick, dizzy, weak, or carbon monoxide detectors in your home indicate an alarm, get to fresh air immediately.
Call emergency services. You may have carbon monoxide poisoning.

UNDERSTANDING THE CO SENSOR’S INDICATOR LIGHTS
See Figure 4.

After shut-off, the RED indicator light in the CO Sensor area of the control panel will flash to provide notification that the generator was shut-off due to carbon monoxide levels rising above a safe threshold.
The RED light will flash for at least five minutes after a CO shut-off.
When it is safe to do so, move the generator to an open, outdoor area far away from occupied spaces with exhaust pointed away. Once relocated to a safe area and the red light is off, the generator can be restarted. Introduce fresh air and ventilate the area where the generator had shut down.
YELLOW| A CO sensor system fault occurred.
When a system fault occurs, the generator is automatically shut down and the YELLOW indicator light in the CO auto-shutoff area
of the control panel will flash to provide notification that a fault has occurred. The YELLOW light will flash for at least five minutes after a fault. The generator can be restarted but may continue to shutoff. A CO sensor fault can only be diagnosed and repaired by an authorized Westinghouse service center.

ELECTRICAL

GENERATOR CAPACITY
NOTICE
Do not overload the generator’s capacity.
Exceeding the generator’s wattage/amperage capacity can damage the generator and/or electrical devices connected to it.
Review the Specifications for this generator and record the running (continuous) and peak (starting) watts. In general the higher the wattage, the more devices can be powered at the same time. The total power requirements of all connected devices must be considered. Power requirements are often listed on a device’s data label or nameplate.
To determine power requirements:

• Choose the devices you want to power simultaneously.
• Record and total the running (continuous) watts of each device. The generator must continuously produce this amount of wattage to keep the devices running.
• Record the peak (starting) watts for each device. This is the momentary surge of power required to start electric motors in some tools and appliances.
• Select the device with the highest peak (starting) wattage.
  Add the peak (starting) watts for that device to the total running (continuous) watts for all the connected devices to determine the total peak wattage requirement for the generator.
  NOTE: Total peak wattage requirement assumes intermittent starting of devices. Adjust estimate if devices reach peak wattage at the same time.

MANAGING GENERATOR POWER
To extend the service life of the generator, use caution when adding electrical loads. Disconnect all loads before starting the generator. The safest way to manage generator power is to add loads sequentially by doing the following:

• Remove all loads and start the generator as described later in this manual.
• Connect and start the largest device or appliance. Power requirements are often listed on a device’s data label or nameplate.
• Allow the generator output to stabilize. Once stable, the engine should run smoothly and the device should function properly.
• Connect and start the next largest device or appliance.
• Allow the generator output to stabilize.
• Repeat this process for each additional load.

EXTENSION CORDS
WARNING
Asphyxiation hazard. Extension cords running directly into the home increase the risk of carbon monoxide poisoning through any openings.
