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.
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.
NOTICE
Only use grounded 3-prong extension cords, tools, and appliances, or double-insulated tools and appliances.

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 2000 ft. (762 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

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.

PAIRING THE REMOTE START

5. Push the Pairing button on the side of the control panel until the START/STOP button illumination turns OFF. Release the button.
6. Turn the generator battery switch to the OFF position. The remote is now paired.

VOLTAGE SELECTOR SWITCH

The 120V/240V selector switch gives the user the ability to double the amperage in the generator for more demanding applications. The voltage selector switches the dual 120V AC windings of the generator to produce 120V or 240V. If a 240V appliance is connected to the 4-prong L14-30R receptacle, the switch must be in the "240V" position. The 120V only outlets will not output power when the Voltage Selector is in the 240V position.

Only change the Voltage Selector Switch with the generator OFF. DO NOT switch the voltage while the generator is running or powering appliances.

BREAK-IN PERIOD
For proper break-in, DO NOT exceed 50% of the rated running watts (2650 watts) during the first five hours of operation.
Vary the load occasionally to allow stator windings to heat and cool and help seat the piston rings.

BEFORE STARTING THE GENERATOR
Verify that:

• The generator is placed in a safe, appropriate location.
• The generator is on a dry, flat, and level surface.
• The engine is filled with oil.
• All loads are disconnected.

Fire and explosion hazard. DO NOT move or tip the generator during operation.

STARTING THE ENGINE

1. Verify that fuel is in the gas tank.
2. Turn the fuel tank valve to the ON position.
   
3. Push the battery switch to the ON position.
4. Choose the starting method:
   1. Remote Start: Push and hold the START button on the remote start key fob for one second.
   2. Push-Button Start: Push and hold the engine START/STOP button for two seconds.
   3. Recoil Start: Manually close the choke if the engine is cold. Firmly grasp and pull the recoil handle slowly until you feel increased resistance, then pull rapidly.
      

Note: During pushbutton or remote start the engine will automatically set the choke and begin the start sequence. If the engine fails to start, the generator will attempt to start the engine two more times.

STOPPING THE ENGINE

1. Turn off and unplug all connected electrical loads.
   
   NEVER start or stop the generator with electrical devices connected.
2. Let the generator run with no load for several minutes to stabilize internal temperatures of the engine.
3. Push and hold the START/STOP button for one second or push STOP on the remote start key fob for one second.

Note: Alternately, if the generator is used infrequently, turn the fuel tank valve to the OFF position to limit the residual fuel remaining in the carburetor float bowl. The engine will stop when fuel in the carburetor and fuel line is exhausted.

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.

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:

   Tool or Appliance Running	Starting Watts*	Watts*
   RV Air Conditioner (11,000 BTU)	1010	1600
   TV (flat screen)	120	235
   RV Refrigerator	180	600
   Radio	200	0
   Light (75 Watts)	300	0
   Coffee Maker	600	0
   Totals	2410	2435
   	Total Running Watts*	2410
   	Highest Starting Watts*	+ 1600
   	Total Starting Watts Needed	4010

   *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.

• 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, or gasoline 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. Turn the fuel tank valve to the OFF position.
2. Locate the drain screw on the bottom of the carburetor float bowl.
   
3. Place an appropriate gasoline container under the drain screw to catch the drained fuel.
4. Loosen the float bowl drain screw and allow the fuel to drain. Tighten the float bowl drain screw.

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 Run/Stop switch to the Stop position.
6. Remove the spark plug.
7. 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.
8. Return the recoil handle gently.
9. Reinstall the spark plug. Leave the spark plug boot disconnected to prevent accidental starting.

FUEL VALVE MAINTENANCE
The fuel valve is equipped with a fuel sediment cup, screen, and o-ring. The fuel valve does not require servicing if the unit is properly maintained with fresh, clean fuel. If fuelrelated troubleshooting is required, perform fuel valve maintenance.

1. Allow the generator to cool completely.
2. Turn the fuel valve to the OFF position.
3. Remove the sediment cup from the fuel valve. Remove the o-ring and screen.
   
4. Wash the sediment cup, o-ring, and screen in a nonflammable solvent. Dry thoroughly.
5. Place the screen and o-ring into the fuel valve. Install the sediment cup and tighten securely.
6. Turn the fuel valve to the ON position and check for leaks. Replace the fuel valve if there is any leakage.
7. Turn the fuel valve to the ON position and check for leaks. Replace the fuel valve if there is any leakage.

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.
   Torque: 106 inch-pound (12 N•m)
8. Perform this procedure for the other valve.
9. Install the gasket, rocker arm cover, and spark plug.
