Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell.

Never use inside a home or garage. EVEN IF doors and windows are open.

Only use OUTSIDE and far away from windows, doors, and vents.

Fire and electrocution hazard. DO NOT connect to a building's electrical system unless the generator and transfer switch have been properly installed and the electrical output has been verified by a qualified electrician. The connection must isolate the generator power from utility power and must comply with all applicable laws and electrical codes.

Electrocution hazard. Never use the generator in a location that is wet or damp. Never expose the generator to rain, snow, water spray, or standing water while in use. Protect the generator from all hazardous weather conditions. Moisture or ice can cause a short circuit or other malfunction in the electrical circuit.

GENERAL SAFETY PRECAUTIONS

• NEVER use the generator to power medical support equipment.
• DO NOT operate the generator when you are tired or under the influence of drugs, alcohol, or medication.
• DO NOT use generator with electrical cords which are worn, frayed, bare, or otherwise damaged.
• All electrical tools and appliances operated from this generator must be properly grounded by use of a third wire or be double-insulated.
• When this generator is used to supply a building wiring system the generator must be installed by a qualified electrician and connected to a transfer switch as a separately derived system in accordance with NFPA 70, National Electrical Code.
• If you begin to feel sick, dizzy, or weak while using the generator, move to fresh air IMMEDIATELY. See a doctor, as you can have carbon monoxide poisoning.
• Only use OUTSIDE and far away from windows, doors, and vents as recommended by the US Department of Health and Human Services Centers for Disease Control and Prevention. Your specific home and/or wind conditions may require additional distance.
• While operating and storing, keep at least five feet
• of clearance on all sides of the generator, including overhead. Allow the generator to cool a minimum of 30 minutes before storage. Heat created by the muffler and exhaust gases could be hot enough to cause serious burns and/or ignite combustible objects.
• DO NOT touch the muffler or engine. They are very HOT and will cause severe burns. DO NOT put body parts or any flammable or combustible materials in the direct path of the exhaust.
• ALWAYS remove any tools or other service equipment used during maintenance away from the generator before operating.
• Avoid skin contact with engine oil or gasoline. Wear protective clothing and equipment. Wash all exposed skin with soap and water.
• A transfer switch must be installed by a licensed electrician approved by the authority having jurisdiction. The installation must comply with all applicable laws and electrical codes.

FUEL SAFETY

• Store fuel in a container approved for gasoline.
• DO NOT smoke when filling the generator with gasoline.
• DO NOT allow the generator's gas tank to overflow when filling.
• Shut down the engine and allow it to cool for two minutes before adding gasoline or oil to the generator.
• NEVER remove the fuel cap when the generator is running. Shut off the engine and allow the unit to cool at least two minutes. Remove the fuel cap slowly to release pressure, keep fuel from escaping around the cap, and to avoid the heat from the muffler igniting fuel vapors. Tighten the fuel cap securely after refueling.
• Wipe spilled fuel from the unit.
• NEVER attempt to burn off spilled fuel.
• NEVER overfill the fuel tank. Leave room for fuel to expand. 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. If fuel is spilled on the generator, wipe up any spills immediately. Dispose of rag properly. Allow area of spilled fuel to dry before operating the generator.
• Wear eye protection while refueling.
• NEVER use gasoline as a cleaning agent.
• Store any containers containing gasoline or LPG/ propane in a well-ventilated area, away from any combustibles or source of ignition.

GASOLINE AND GASOLINE VAPOR (GAS)

Fire and explosion hazard. Gasoline and LPG/propane are highly explosive and flammable and can cause severe burns or death.

• In case of a gas fire,DO NOT attempt to extinguish the flame if the fuel tank valve is in the ON position. Introducing an extinguisher to a generator with an open fuel valve could create an explosion hazard.
• Gas has a distinctive odor, this will help detect potential leaks quickly.
• Gas vapors can cause a fire if ignited.
• Gasoline is a skin irritant and needs to be cleaned up immediately if it comes in contact with the skin.

LIQUID PETROLEUM GAS (LPG/PROPANE)

Fire and explosion hazard. NEVER use a gas container, LPG/propane connector hose, LPG/propane tank or any other fuel item that appears to be damaged.

Fire and explosion hazard. Only use approved LPG/ propane tanks with an Overfilling Prevention Device (OPD) valve. ALWAYS keep the tank in a vertical position with the valve on top and placed at ground level on a flat surface. DO NOT allow tanks to be near any heat source. When transporting and storing, turn the propane tank valve to the fully closed position and disconnect the tank. Make sure to ALWAYS cover the generator inlet and tank outlet with protective plastic caps.

• LPG/Propane is highly flammable and explosive.
• Flammable gas under pressure can cause a fire or explosion if ignited.
• LPG/Propane can settle in low places because it is heavier than air.
• LPG/Propane has a distinctive odor added to help detect potential leaks.
• ALWAYS keep a LPG/Propane tank in an upright position.
• When exchanging LPG/propane tanks, be sure the tank valve is the same type.
• In case of a LPG/propane fire,DO NOT attempt to extinguish unless the fuel supply can be shut off safely.
• LPG/propane will burn the skin. Prevent skin contact at all times.
• Keep the propane tank away from the generator exhaust.
• Large (500–1000 gallon) LPG/propane tanks will require a certified plumber to install the fuel line to the generator and the loose regulator is not used (the regulator that is attached to the fuel tank). The pressure as measured at the regulator mounted to the generator must be 7" to 14" of water column. A certified plumber must ensure that the pressure is correct or install a step down regulator if needed.

Fire and explosion hazard. If there is a strong smell of propane while operating the generator, fully close the LPG/propane tank valve immediately. Once the propane is off, use soapy water to check for leaks on the hose and connections on the tank valve and the generator. DO NOT smoke or light a cigarette or check for leaks using any open flame source such as a match or lighter. If a leak is found, contact a qualified technician to inspect and repair the LPG/propane system before using the generator.

When starting the generator:

• Make sure that the fuel cap, air filter, spark plug, fuel lines, and exhaust system are properly in place.
• If you spill any gasoline on the tank, allow it to fully evaporate before operating.
• Make sure the generator and LPG/propane tank are on a flat surface before operating.
• If there is a propane odorDO NOT start the unit because there may be a potential leak. NEVER place a LPG/ propane tank near the engine exhaust.

When transporting or servicing the generator:

• Make sure the LPG/propane tank and LPG/propane hose are not attached to the generator.
• Disconnect the spark boot to prevent accidental starting.

When storing the generator:

• Store away from sparks, open flames, pilot lights, heat, and other sources of ignition.
• DO NOT store gas or a LPG/propane tank near furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions.

SAFETY LABELS AND DECALS

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, notifies the user with a RED indicator light, and directs the user to read the Action Label for steps to take. The CO Sensor DOES NOT replace carbon monoxide alarms. Install battery-powered carbon monoxide alarm(s) in your home.

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. 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.

OPERATION

GENERATOR LOCATION
Read and understand all safety information before starting the generator.

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell.

Never use inside a home or garage. EVEN IF doors and windows are open.

Only use OUTSIDE and far away from windows, doors, and vents.
NEVER operate the generator inside any building, including garages, basements, crawlspaces, sheds, enclosure, or compartment, including the generator compartment of a recreational vehicle.

Electrocution hazard. NEVER use the generator in a location that is wet or damp. NEVER expose the generator to rain, snow, water spray, or standing water while in use. Protect the generator from all hazardous weather conditions. Moisture or ice can cause a short circuit or other malfunction in the electrical circuit. Using a generator or electrical appliance in wet conditions, such as rain or snow, or near a pool or sprinkler system, or when your hands are wet, could result in electrocution

Fire hazard. Only operate the generator on a solid, level surface. Operating the generator on a surface with loose material such as sand or grass clippings can cause debris to be ingested by the generator that could block cooling vents or the air intake system. Allow the generator to cool for 30 minutes before transport or storage.

The generator should be on a flat, level surface at all times (Even while not in operation). The generator must have at least 5 ft. (1.5 m) of clearance from all combustible material.
DO NOT operate the generator in the back of a SUV, camper, trailer, truck bed (regular, flat, or otherwise), under stairs, next to walls or buildings, or in any other location that will not allow for adequate cooling of the generator and/or the muffler. DO NOT contain generators during operation.

Asphyxiation hazard. Place the generator in a wellventilated area. DO NOT place the generator near vents or intakes where exhaust fumes could be drawn into occupied or confined spaces. Carefully consider wind and air currents when positioning the generator.

GROUNDING

Shock hazard. Failure to properly ground the generator can result in electric shock.
NOTICE
Only use grounded 3-prong extension cords, tools, and appliances, or double-insulated tools and appliances.

The generator neutral is floating. The generator ground terminal is connected to the frame of the generator, the metal non-current-carrying parts of the generator, and the ground terminals of each receptacle. The generator (stator winding) is isolated from the frame and from the AC receptacle ground pin. Electrical devices that require a grounded receptacle pin connection may not function properly.
If this generator will be used only with cord and plug equipment connected to the receptacles mounted on the generator, National Electric Code does not require that the unit be grounded. However, other methods of using the generator may require grounding to reduce the risk of shock or electrocution.
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.

HIGH ALTITUDE OPERATION
Engine power is reduced the higher you operate above sea level. Output will be reduced approximately 3.5% for every 1000 feet of increased altitude from sea level.
High altitude adjustment is required for operation at altitudes over 5,000 ft. (1524 m). Operation without this adjustment will cause decreased performance, increased fuel consumption, and increased emissions.
NOTICE
DO NOT operate the generator at altitudes below 2,000 ft. (762 m) with the high altitude kit installed. Engine damage may occur.
High Altitude Carburetor Kit: Part# 518965
High Altitude DF Regulator: Part# 518516
Note: You must purchase both the Dual Fuel Regulator and Carburetor Kit for proper high altitude operation.

REMOTE START

Verify that the area around the generator is clear before remote starting the generator.
The remote start key fob included with the generator should be attached to the recoil handle or control panel. If your unit was shipped without a key fob, contact Westinghouse customer service.
The generator can be started remotely from up to 99 feet (30 meter) using the remote start key fob.
Note: As the batteries in the remote start key fob drain, operational distance will decrease.

FREQUENCY OF USE
If the generator will be used on an infrequent or intermittent basis (more than one month before next use), refer to the Storage section of this manual for information regarding fuel deterioration.

AC CIRCUIT BREAKERS
The circuit breakers will automatically switch OFF if there is a short circuit or a significant overload of the generator at each receptacle.
If an AC circuit breaker switches OFF automatically, check that the appliance is working correctly and it does not exceed the rated load capacity of the circuit before resetting the AC circuit breaker ON.

ECO MODE
NOTICE
Always start the generator with ECO MODE OFF. Allow the engine speed to stabilize and the OUTPUT READY LED to illuminate before switching ECO MODE ON.
Note: Do not use ECO MODE when in parallel operation with another Westinghouse generator.
ECO MODE minimizes fuel consumption and noise by adjusting the engine RPM to the minimum required for the current load.
Turn ECO MODE ON when powering small appliances with continuous loads such as a computer or electric light.
Turn ECO MODE OFF when powering large surge loads such as an air conditioner or electric pump.
To turn on ECO MODE, verify that the OUTPUT READY LED is illuminated green, then push the switch to the ON position. If no load is present, the generator RPM will drop to idle speed. The generator will detect loads as they are applied and increase engine RPM.
To run the generator at maximum power and RPM, push the ECO MODE switch to the OFF position.

OVERLOAD RESET
The generator will automatically switch OFF all AC output to protect the generator if overloaded or if there is a short circuit in a connected appliance. However, the engine will continue to run. Marginal overloading that temporarily illuminates the OVERLOAD LED may shorten the service life of the generator.
OVERLOAD on the control panel will illuminate red and the green OUTPUT READY will be OFF.

To restore AC output:

1. Turn off and unplug all connected electrical loads.
2. Push the RESET button on the control panel until the OVERLOAD LED goes OFF and the OUTPUT READY LED is illuminated.
3. Reset the circuit breakers if OFF.
4. Verify that the intended running and surge loads do not exceed the generator's capacity.
5. Reconnect electrical loads sequentially, allowing the generator to stabilize after each load is connected.

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.
Make sure the generator can supply enough continuous (running) and surge (starting) watts for the items you will power at the same time.
The total power requirements (Volts x Amps = Watts) of all appliances connected must be considered. Appliance and power tool manufacturers usually list rating information near the model or serial number.
To determine power requirements:

1. Select the items you will power at the same time.
2. Total the continuous (running) watts of these items. This is the amount of power the generator must produce to keep the items running. See the wattage reference chart.
3. Estimate how many surge (starting) watts you will need. Surge wattage is the short burst of power needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator. Because not all motors start at the same time, total surge watts can be estimated by adding only the item(s) with the highest additional surge watts to the total rated watts from step 2.

Example:

*Wattages listed are approximate. Verify actual wattage.

POWER MANAGEMENT
To prolong the life of the generator and attached devices, use care when adding electrical loads to the generator. There should be nothing connected to the generator outlets before starting the engine. The correct and safe way to manage generator power is to sequentially add loads as follows:

1. With nothing connected to the generator, start the engine as described in this manual.
2. Plug in and turn on the first load, preferably the largest load you have.
3. Permit the generator output to stabilize (engine runs smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeat steps 4 and 5 for each additional load.

Wattage Reference

*Wattages listed are approximate. Verify actual wattage.

EXTENSION CORDS

Asphyxiation hazard. Extension cords running directly into the home increase the risk of carbon monoxide poisoning through any openings. If an extension cord running directly into your home is used to power indoor items, there is a risk of carbon monoxide poisoning to people inside the home. Always use battery-powered carbon monoxide detector (s) that meet current UL 2034 safety standards when running the generator. Regularly check the detector (s) battery.

Asphyxiation hazard. When operating the generator with extension cords, make sure the generator is located in an open, outdoor area, far away from occupied spaces with exhaust pointed away.

Fire and electrocution hazard. Never use worn or damaged extension cords. Damaged or overloaded extension cords could overheat, arc, and burn resulting in death or serious injury.
Before connecting an AC appliance or power cord to the generator:

• Use grounded 3-prong extension cords, tools, and appliances, or double-insulated tools and appliances.
• Make sure the tool or appliance is in good working order. Faulty appliances or power cords can create a potential for electric shock.
• Make sure the electrical rating of the tool or appliance does not exceed the rated power of the generator or the receptacle being used.

EXTENSION CORD SIZING
Only use grounded 3-prong extension cords marked for outdoor use that are rated for the electrical load.

PARALLEL OPERATION

Fire and electrocution hazard. Never connect or disconnect the parallel cord leads when a generator is running.
NOTICE
Connecting the iGen4500DFc to a generator that is not compatible can cause a low voltage output that can damage tools and appliances powered by the generator.
Parallel operation gives you the ability to link the iGen4500DFc to a compatible Westinghouse Inverter Generator for combined running and peak power output. A Westinghouse parallel cord (purchased separately) is required for parallel operation. This cord can be purchased from an authorized Westinghouse Generator dealer.
Note: Do not use ECO MODE when in parallel operation with another Westinghouse generator.

Parallel cord (50A/6000 Watts): Part# 507PC
Note: Compatible Westinghouse generators without parallel ports can be operated in parallel with the receptacle-mounted parallel cable, Part# 260041.

1. Make sure the battery switch and the ECO MODE switch are in the OFF position.
2. Connect the black and red parallel cable leads to the black parallel ports on each corresponding generator control panel as shown below. Connect the black lead to the left port, the red lead to the right port.
   Note: DO NOT connect two red leads or two black leads into the same generator.
   
3. Connect the green ground lead to the ground terminal on each generator and tighten the nut.
4. Start one of the generators and wait until the OUTPUT READY LED illuminates.
5. Start the second generator and wait until the OUTPUT READY LED illuminates before connecting a load.
6. Connect additional loads as described in Power Management.
7. Unplug all loads before stopping the generators.

TRANSPORTING

Weight hazard. Always have assistance when lifting the generator.

• Allow the generator to cool a minimum of 30 minutes before transporting.
• If operating on LPG, turn the propane tank valve to the fully closed position.
• Disconnect the LPG/propane hose from the generator and propane tank.
• Replace all protective covers on the generator control panel.
• Only use the generator's fixed handle(s) to lift the unit or attach any load restraints such as ropes or tie-down straps. Do not attempt to lift or secure the generator by holding onto any of its other components.
• Keep the unit level during transport to minimize the possibility of fuel leakage or, if possible, drain the fuel or run the engine until the fuel tank is empty before transport.
• The generator wheels are only intended for hand transport. The wheels are not suitable for towing the generator either on or off-road.
• Use the extendable handle for one-person, hand transport. To deploy the handle, push on the locking button and pull on the handle until it's fully extended. To stow it, push on the locking button and push on the handle until it's fully retracted. Only extend or retract the handle while the generator is OFF, stationary, and resting on a horizontal surface. Do not use the extendable handle to lift the generator entirely off the ground, tow it, or up-end it.

STORAGE
Proper storage preparation is required for trouble-free operation and generator longevity.
NOTICE
Gasoline stored for as little as 30 days can deteriorate, causing gum, varnish, and corrosive buildup in fuel lines, fuel passages and the engine. This corrosive buildup restricts the flow of fuel, which can prevent the engine from starting after a prolonged storage period. The use of fuel stabilizer significantly increases the storage life of gasoline. Full-time use of fuel stabilizer is recommended. Follow the manufacturer's instructions for use.

SHORT TERM STORAGE

• Allow the generator to cool a minimum of 30 minutes before storage.
• If operating on LPG, turn the propane tank valve to the fully closed position and disconnect the LPG/propane hose from the generator and propane tank.
• Replace all protective covers on the generator control panel.
• Wipe the generator with a moist cloth. Clean any debris from the air inlets under the control panel and muffler cooling vents.
• Store the generator in a well-ventilated, dry location away from sparks, open flames, pilot lights, heat, and other sources of ignition such as areas with a sparkproducing electric motor or where power tools are operated.
• Do not store the generator, gasoline, or propane tanks near furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions.
• With the engine and exhaust system cool and all surfaces dry, cover the generator to keep out dust. Do not use a plastic sheet as a dust cover. Non-porous materials trap moisture and promote rust and corrosion.

LONG TERM STORAGE
Even properly stabilized fuel can leave residue and cause corrosion if left long term. If storing the generator for two to six months, drain the float bowl to prevent gum and varnish buildup in the carburetor.

DRAINING THE FLOAT BOWL

1. Remove the engine service cover.
2. Locate the drain hose extending from the bottom of the carburetor float bowl.
   
3. Place the loose end of the hose outside the generator into an approved gasoline container to catch the drained fuel.
4. Loosen the float bowl drain screw and allow the fuel to drain. Tighten the float bowl drain screw.
5. Route the drain hose between the air cleaner housing and the engine service cover. Install the engine service cover.

DRAINING THE FUEL TANK
If storing the generator for longer than six months, drain the fuel tank to prevent fuel separation, deterioration, and deposits in the fuel system.

1. Unscrew the fuel tank cap. Remove the fuel screen filter by slightly compressing it while removing it from the tank.
2. Using a commercially available gasoline hand pump (not included), siphon the gasoline from the fuel tank into an approved gasoline container. DO NOT use an electric pump.
3. Reinstall the fuel screen filter and the fuel tank cap.
4. Start the generator and allow it to run until the generator engine stops.
5. Push the battery switch to the OFF position.
6. Disconnect the battery quick-connect plug.
7. Remove the spark plug.
8. Put a teaspoon of engine oil into the cylinder and pull the recoil handle until resistance is felt. At this position the piston is coming up on its compression stroke and both valves are closed. Storing the engine in this position will help prevent internal corrosion. Return the recoil handle gently.
9. Reinstall the spark plug. Leave the spark plug boot disconnected to prevent accidental starting.
10. Install the engine service cover.

VALVE CLEARANCE
NOTICE
Checking and adjusting valve clearance must be done when the engine is cold.

1. Remove the rocker arm cover and carefully remove the gasket. If the gasket is torn or damaged, it must be replaced.
2. Remove the spark plug so the engine can be rotated more easily.
3. Rotate the engine to top dead center (TDC) by pulling the recoil handle slowly. Looking through the spark plug hole, the piston should be at the top (both valves are closed).
4. Both the rocker arms should be loose at TDC on the compression stroke. If they are not, rotate the engine 360°.
5. Insert a feeler gauge between the rocker arm and the valve stem to measure valve clearance.
   

   	Intake Valve	Exhaust Valve
   Valve Clearance	0.0031 – 0.0047 in (0.08 – 0.12 mm)	0.0051 – 0.0067 in (0.13 – 0.17 mm)
   Torque	8-12 N•m	8-12 N•m

6. If an adjustment is necessary, hold the rocker arm pivot and loosen the pivot adjusting nut.
7. Turn the rocker arm pivot to obtain the specified clearance. Hold the rocker arm pivot and re-tighten the pivot adjusting nut to the specified torque.
