Operation

Generator Location

Read and understand all safety information before starting the generator.

DANGER: 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.

DANGER: 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.

WARNING: Fire hazard. Only operate the generator on a solid, level surface. Operating on a surface with loose material can cause debris ingestion, blocking 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. Maintain 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, under stairs, next to walls or buildings, or in any location that prevents adequate cooling of the generator and/or muffler. DO NOT contain generators during operation.

DANGER: Asphyxiation hazard. Place the generator in a well-ventilated area. DO NOT place near vents or intakes where exhaust fumes could be drawn into occupied or confined spaces. Consider wind and air currents when positioning.

Grounding

WARNING: 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 ground terminal connects to the frame, non-current-carrying parts, and receptacle ground terminals. The generator (stator winding) is isolated from the frame and receptacle ground pin. Devices requiring a grounded receptacle pin may not function properly.

If using only cord and plug equipment connected to the generator's receptacles, grounding is not required by the National Electric Code. However, other uses may require grounding to reduce shock or electrocution risk.

Before using the ground terminal, consult a qualified electrician, electrical inspector, or local agency for applicable codes.

High Altitude Operation

Engine power is reduced at higher altitudes. Output decreases approximately 3.5% for every 1000 feet above sea level. High altitude adjustment is required for operation above 2,000 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.

Note: Purchase the Dual Fuel Regulator and Carburetor Kit for proper high altitude operation.

Voltage Selector Switch

The 120V/240V selector switch allows doubling amperage for demanding applications. It switches dual 120V AC windings to produce 120V or 240V. If a 240V appliance is connected to the L14-30R receptacle, the switch must be in the “240V” position. 120V outlets will not output power when the Voltage Selector is in the 240V position.

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

Fuel Selector Switch

Position the fuel selector switch on the front control panel to the desired fuel choice.

Turn the fuel selector switch fully upward for gasoline operation.

Turn the fuel selector switch fully downward for propane operation.

Break-in Period

Frequency of Use

If the generator will be used infrequently (more than one month before next use), refer to the Storage section for information regarding fuel deterioration.

AC Circuit Breakers

The circuit breakers automatically switch OFF if there is a short circuit or a significant overload at any receptacle. If a breaker trips, check that the appliance is working correctly and does not exceed the rated load capacity of the circuit before resetting the breaker.

Generator Capacity

NOTICE: DO NOT overload the generator's capacity. Exceeding capacity can damage the generator and/or connected electrical devices. Ensure the generator can supply enough continuous (running) and surge (starting) watts for all items powered simultaneously.

Total power requirements (Volts x Amps = Watts) of all connected appliances must be considered. 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. 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:

Total Running Watts: 2590

Highest Starting Watts: + 1600

Total Starting Watts Needed: 4190

*Wattages listed are approximate. Verify actual wattage.

*Wattages listed are approximate. Verify actual wattage.

Extension Cords

7. Install the oil dipstick and hand-tighten.

NOTICE: DO NOT pollute. Follow EPA or other governmental agency guidelines for proper disposal of hazardous materials. Consult local authorities or reclamation facility.

Spark Plug Maintenance

Inspect and clean the spark plug after every 100 hours of use or six months. Replace after 300 hours or every year.

NOTICE: ALWAYS use the Westinghouse OEM or compatible non-resistor-type spark plug. Resistor-type plugs can cause rough idling, misfire, or prevent starting.

1. Place the generator on a level surface and allow the engine to cool.
2. Remove the spark plug boot by firmly pulling it away from the engine.
3. Clean the area around the spark plug.
4. Remove the spark plug with the included spark plug socket wrench.

NOTICE: NEVER apply side load or move the spark plug laterally when removing.

5. Inspect the spark plug. Replace if electrodes are pitted, burned, or the insulator is cracked. Use only a recommended replacement plug.
6. Measure the spark plug electrode gap with a wire-type feeler gauge. Correct the gap by carefully bending the side electrode if necessary.

Spark plug gap: 0.024 – 0.032 in. (0.60 – 0.80 mm)

7. Carefully install the spark plug finger tight, then tighten an additional 3/8 to 1/2 turn with the spark plug wrench.
8. Attach the spark plug boot.

Fuel Valve Maintenance

The fuel valve has an inline fuel filter. The filter requires no servicing if the unit is properly maintained with fresh, clean fuel. If fuel-related troubleshooting is needed, perform fuel valve maintenance.

1. Allow the generator to cool completely.
2. Place an appropriate gasoline container under the carburetor drain bolt to catch drained fuel.
3. Remove the drain bolt on the bottom of the carburetor and allow the fuel tank to drain completely. Install and tighten the drain bolt securely.
4. Remove the fuel line from the fuel valve. Be prepared to capture remaining fuel.
5. Loosen the retaining bolt. Unscrew and remove the fuel valve from the fuel tank. Be prepared to capture any remaining fuel.
6. Open the fuel valve. Use compressed air to clean the fuel filter and the fuel passage from the fuel line side.
7. Install and tighten the fuel valve until it has a few threads remaining and is facing outward.
8. Hold it in place and tighten the retaining bolt. DO NOT overtighten.
9. Replace the fuel line and secure with the clamp.

Spark Arrestor Service

Allow the muffler to cool completely before servicing the spark arrestor. Check and clean after every 100 hours or six months. Failure to clean results in degraded engine performance.

1. Place the generator on a level surface.
2. Slide a screwdriver into the side slot and remove the screw holding clamp (A) on the spark arrestor. Pull out the spark arrestor assembly.
3. Carefully remove carbon deposits from the spark arrestor screen with a wire brush. The spark arrestor must be free of breaks and tears. Replace if damaged.
4. Reinstall the spark arrestor.

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 buildup can prevent the engine from starting after prolonged storage. Fuel stabilizer significantly increases gasoline storage life. Full-time use is recommended. Follow manufacturer's instructions.

Short Term Storage

• Allow the generator to cool a minimum of 30 minutes before storage.
• If operating on propane, turn the propane tank valve to the fully closed position and disconnect the LPG/propane hose.
• Replace all protective covers on the generator control panel.
• Wipe the generator with a moist cloth. Clean debris from muffler cooling vents.
• Store in a well-ventilated, dry location away from sparks, open flames, pilot lights, heat, and other ignition sources.
• DO NOT store generator, gasoline, or propane tanks near furnaces, water heaters, or other heat-producing appliances with automatic ignitions.
• With the engine and exhaust system cool and surfaces dry, cover the generator to keep out dust. DO NOT use a plastic sheet; non-porous materials trap moisture and promote rust and corrosion.

Long Term Storage

Even stabilized fuel can leave residue and cause corrosion. If storing 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 drained fuel.
4. Loosen the float bowl drain screw and allow fuel to drain. Tighten the drain screw.

Draining the Fuel Tank

If storing for longer than six months, drain the fuel tank to prevent fuel separation, deterioration, and deposits.

1. Unscrew the fuel tank cap. Remove the fuel screen filter by slightly compressing it while removing it from the tank.
2. Using a gasoline hand pump (not included), siphon gasoline from the fuel tank into an approved container. DO NOT use an electric pump.
3. Reinstall the fuel screen filter and fuel tank cap.
4. Start the generator and allow it to run until the 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. This positions the piston on its compression stroke with valves closed, helping prevent internal corrosion. Return the recoil handle gently.
8. Reinstall the spark plug. Leave the spark plug boot disconnected to prevent accidental starting.

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. Replace if torn or damaged.
2. Remove the spark plug so the engine can be rotated more easily.
3. Rotate the engine to top dead center (TDC) by slowly pulling the recoil handle. The piston should be at the top (both valves closed).
4. Both rocker arms should be loose at TDC on the compression stroke. If not, rotate the engine 360°.
5. Insert a feeler gauge between the rocker arm and valve stem to measure valve clearance.

6. If 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 pivot and re-tighten the 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.
