SAFETY LABELS AND DECALS

FUEL SAFETY

Gasoline and liquid petroleum gas (LPG) are highly explosive and flammable. Explosions and fire can cause severe burns or death.

Gasoline and gasoline vapor (Gas)

• Gasoline is highly flammable and explosive.
• Gas expands and contracts with different temperatures.
• In case of a gas fire, do not attempt to extinguish the flame if the fuel shutoff 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 (Propane/LPG)

• 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 LPG/Propane tank in an upright position.
• When exchanging LPG/Propane tanks, be sure the tank value is the same type.
• In case of a LPG/Propane fire, do not attempt to extinguish unless the fuel supply can be shut off.
• LPG/Propane will burn the skin. Prevent skin contact at all times.

Never use a gas container, LPG connector hose, LPG tank or any other fuel item that appears to be damaged.

When starting generator:

• Make sure that the gas 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 propane tank are on a flat surface before operating.
• If there is a propane odor do not start the unit because there may be a potential leak.
• Never place propane tank near engine exhaust.

When transporting or servicing the generator:

• Make certain the fuel shutoff valve is off and the fuel tank is empty.
• Make sure the LPG tank and LPG hose is not attached to the generator.
• Disconnect the spark plug wire.

When storing the generator:

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

Only use approved LPG tanks with OPD (overfilling prevention device) valve. Always keep the tank in a vertical position with the valve on top and installed at ground level on a flat surface. Do not allow tanks to be around any heat source and make sure it is not exposed to the sun, rain and dust. When transporting and storing, turn off the tank valve and fuel valve, and disconnect the tank. Make sure to always cover the generator and tank outlet with protective plastic caps.

Do not allow children to tamper or play with the propane tank or hose connections.

If there is a strong smell of propane while operating the generator close the valve on the propane tank 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 system before using the generator.

OPERATION

BEFORE STARTING THE GENERATOR

BEFORE STARTING THE GENERATOR, REVIEW SAFETY SECTION STARTING.
Location Selection – Before starting the generator, avoid exhaust and location hazards by verifying:

• You have selected a location to operate the generator that is outdoors and well ventilated.
• You have selected a location with a level and solid surface on which to place the generator.
• You have selected a location that is at least 15 feet (4.5 m) away from any building, other equipment or combustible material.
• If the generator is located close to a building, make sure it is not located near any windows, doors and/or vents.

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.

Avoid other generator hazards.
READ MANUAL BEFORE USE.

Always operate the generator on a level surface. Placing the generator on non level surfaces can cause the generator to tip over, causing fuel and oil to spill. Spilled fuel can ignite if it comes in contact with an ignition source such as a very hot surface.
NOTICE
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
• Block air intake system

Weather – Never operate your generator outdoors during rain, snow or any combination of weather conditions that could lead to moisture collecting on, in or around the generator.
Dry Surface – Always operate the generator on a dry surface free of any moisture.
No Connected Loads – Make sure the generator has no connected loads before starting it. To ensure there are no connected loads, unplug any electrical extension cords that are plugged into the control panel receptacles.
NOTICE
Starting the generator with loads already applied to it could result in damage to any appliance being powered off the generator during the brief start-up period.
Grounding the Generator – The National Electric Code (NEC), as well as many local electrical codes, may require the generator to be connected to earth ground. The most common application that requires a ground rod is when you are using the generator as a separately derived system to provide back up power to your house. Typically this is when a transfer switch has a switched neutral.
As the generator application has many variables that cannot be determined by the manufacturer of the generator, a licensed electrician will need to determine if a grounding rod is needed.
If a licensed electrician has determine the application requires a ground rod, make sure it is connected to earth ground by connecting the ground terminal on the control panel to earth ground using copper wire (minimum 10 AWG). Consult a qualified electrician for local grounding requirements.
Neutral Bonded: There is a permanent conduct or between the generator (stator winding) and the frame.

Be sure the generator is properly connected to earth ground before operating. The generator must be grounded to prevent electrical shock due to faulty appliances.

High Altitude Operation
Engine power is reduced the higher you operate above sea level. Output will be reduced approximately 3.5% for every 1000ft of increased altitude from sea level. This is a natural occurrence and cannot be adjusted by engine. Increased exhaust emissions can also result due to increased fuel mixture. Other issues include hard starting, increased fuel consumption and spark plug fouling. Contact our service team 1-855-944-3571 for altitude part kits.

POWERCORD

Using Extension Cords
Westinghouse Outdoor Power Equipment assumes no responsibility for the content within this table. The use of this table is the responsibility of the user only. This table is intended for reference only. The results produced by using this table are not guaranteed to be correct or applicable in all situations as the type and construction of cords are highly variable. Always check with local regulations and a licensed electrician prior to installing or connecting an electrical appliance.

Using Westinghouse Power Cord
Use the extension cord chart to determine the size of the conductor for extension cord applications. Determine the distance of the generator to the appliance on the top line of the chart. Then select the rated amperage of the generator on the left side of the chart. Where the two meet is the size of the conductor required for the application.
The Westinghouse power cord (shown right) is connected to the generator at the L14-30R 120/240 plug. The opposite end of the power cord is a fan tail receptacle with 2 green receptacles and 2 red receptacles. Each receptacle is rated at 120 volts AC. To balance the load on the generator's alternator, use the red and green identifiers on the fan tail receptacle. To keep the load balanced, connect the loads so that both color receptacles are used. An example is one in red and one in green. Do not connect 2 in red and none in green, or 2 in green and none in red. If only one color receptacle is used with multiple loads, the alternator may experience an unbalanced load, causing undue vibration to generator.

CONNECTING THE GENERATOR TO A BUILDING ELECTRICAL SYSTEM

It is recommended to use a manual transfer switch when connecting directly to a buildings electrical system. Connecting a portable generator to a buildings electrical system must be made in strict compliance with all national and local electrical codes and laws, and be completed by a qualified electrician.

TRANSFER SWITCH CONNECTIONS

1. Alternator Neutral Ground Wire (white/Green)
2. Alternator Bonded Jumper Wire (white/Green)

The Westinghouse generator is wired with the neutral bonded to ground. If you are connecting your generator to a panel board transfer switch, a licensed electrician will need to consider removing the bonded neutral to ensure proper operation of household GFCI circuits. Begin by removing the alternator cover. Once the cover is off remove the nut that holds the bonded ground jumper wire (see "2" in Figure 5). Once the nut is removed take the bonded jumper wire off and re-secure the nut. Next remove the screw holding the neutral ground wire (see "1" in Figure 5). Attach the bonded jumper wire (2) to the neutral ground (1) and tighten the screw.
If the bonded neutral is removed the generator must be relabeled as floating neutral on the control panel.
If your generator is equipped with GFCI receptacles, removing the bonded neutral may not allow proper operation of the GFCI receptacles. Always keep the jumper wire in case it is needed for future use when not connected to a transfer switch.

ADDING / CHECKING ENGINE FLUIDS AND FUEL

BEFORE ADDING/CHECKING ENGINE FLUIDS AND FUEL, REVIEW SAFETY SECTION STARTING.

Filling the fuel tank with gasoline while the generator is running can cause gasoline to leak and come in contact with hot surfaces that can ignite the gasoline.
Before starting the generator, always check the level of:

• Engine oil
• Gasoline in the fuel tank

Once the generator is started and the engine gets warm, it is not safe to add gasoline to the fuel tank or engine oil to the engine while the engine is running or the engine and muffler are hot.

CHECKING AND / OR ADDING ENGINE OIL

Internal pressure can build in the engine crankcase while the engine is running. Removing the oil fill plug/ dipstick while the engine is hot can cause extremely hot oil to spray out of the crankcase and can severely burn skin. Allow engine oil to cool for several minutes before removing the oil fill plug/dipstick.
The unit as shipped does not contain oil in the engine. You must add engine oil before starting the generator for the first time. See Checking Engine Oil and Adding Engine Oil for instructions on checking engine oil level and the procedure for adding engine oil.
NOTICE
The engine does not contain engine oil as shipped. Attempting to start the engine can damage engine components. The owner of the generator is responsible to ensure the proper oil level is maintained during the operation of the generator. Failure to maintain the proper oil level can result in engine damage.
NOTICE
During the first five hours of operating the generator make sure to not exceed 50% of the rated running watts until the unit is broken in properly. Make sure to vary to load occasionally to allow stator windings to heat and cool. Adjusting the load will also help seat piston rings. Check oil more often during the first couple times of operating the generator.
NOTICE
Weather will affect engine oil performance. Change the type of engine oil used based on weather conditions to suit the engine needs.

ADDING GASOLINE TO THE FUEL TANK

BEFORE ADDING GAS TO THE TANK PLEASE REVIEW FUEL SAFETY SECTION

Never refuel the generator while the engine is running.
Always turn the engine off and allow the generator to cool before refueling.

Required Gasoline – Only use gasoline that meets the following requirements:

• Unleaded gasoline only
• Gasoline with maximum 10% ethanol added
• Gasoline with an 87 octane rating or higher

Filling the Fuel Tank – Follow the steps below to fill the fuel tank:

1. Shut off the generator.
2. Allow the generator to cool down so all surface areas of the muffler and engine are cool to the touch.
3. Move the generator to a flat surface.
4. Clean area around the fuel cap.
5. Remove the fuel cap by rotating counterclockwise.
6. Slowly add gasoline into the fuel tank. Be very careful not to overfill the tank. The gasoline level should NOT be higher than the filler neck.
   
7. Install the fuel cap by rotating clockwise until you hear a click, indicating the cap is completely installed.

Avoid prolonged breathing of gasoline vapors.

CONNECTING TO STANDARD LPG/PROPANE TANK

BEFORE CONNECTING PROPANE TANK TO THE GENERATOR PLEASE REVIEW FUEL SAFETY SECTION

Connecting LPG Tank

1. Make sure the generator is off, on a flat surface in well ventilated area.
2. Make sure propane tank valve is in the off position.
3. Make sure the fuel selector switch on the generator control panel is pointing downward to "Propane".
4. Remove the plastic cover on the generator propane inlet valve.
5. Using your fingers tighten the LPG hose (included) end below to the generator propane inlet. DO NOT OVER- TIGHTEN 35-88 Ib-in maximum.
   
6. Attach the other end of the hose to a tank of LPG/ Propane and hand tighten.
7. Check all connections for leaks by wetting the fittings with soapy water. Anywhere that bubbles appear or grow indicates a leak in the connection. If a leak exists at a fitting then turn off the tank valve and tighten the fitting. Turn the gas back on and recheck with soapy water again. If the leak continues or if the leak is not at a fitting then do not use the generator and contact customer service.

NOTICE

• When using standard 20 or 30 pound capacity LPG tanks, make sure they have Type 1, right hand Acme threads.
• Verify the requalification date on the tank has not expired.
• All new tanks must be purged of air and moisture prior to filling. Used tanks that have not been plugged or kept closed must also be purged
• The purging process should be done by a LPG supplier. (Tanks from an exchange supplier should have been purged and filled properly already)
• Always position the tank so the connection between the valve and the gas inlet won't cause sharp bends or kinks in the hose.

Do not start generator if you smell propane. This may result in explosion hazard. Do not use provided LPG hose for any other appliances. Always turn off the propane tank and disconnect LPG hose when not in use.

CONNECTING TO LARGE LPG/PROPANE TANK

BEFORE CONNECTING PROPANE TANK TO THE GENERATOR PLEASE REVIEW FUEL SAFETY SECTION
You can hook up you Duel Fuel Generator to a large home LP tank. It is required that you consult a plumber to properly connect your generator to the tank.
To properly connect with a large propane tank you must first check and confirm the LP fuel pressure at the outlet of the LP tank. The LP fuel pressure should be 14-10" of water column, which is the standard fuel pressure for residential gas fired appliances.
If the LP fuel pressure is within the 14-10" water column range, the primary fuel regulator should be removed from the fuel line components. Then plumb directly from the LP tank to the secondary regulator assembled to the generator.

You must consult a certified plumber to connect to large LP tank safely.

BEFORE STARTING THE GENERATOR

BEFORE STARTING THE GENERATOR, REVIEW SAFETY SECTION STARTING.
Before attempting to start the generator, verify the following:

• The engine is filled with engine oil.
• The generator is situated in a proper location.
• The generator is on a dry surface.
• All loads are disconnected from the generator.
• The generator is properly grounded.
• Propane connection is secure with no leaks or damage.

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.
Never operate the generator in an enclosed area. Engine exhaust contains carbon monoxide. Only operate the generator outside and away from windows, doors and vents.
NOTICE
The engine is equipped with a low oil shutdown switch. If the oil level becomes low, the engine may shut down and not start until the oil is filled to the proper level. Poor oil quality may interfere with the operation of the low oil shutdown switch.
The owner of the generator is responsible to ensure the proper oil level is maintained during the operation of the generator. Failure to maintain the proper oil level can result in engine damage.
NOTICE
When operating on LPG it is common for frost to form on the tank and regulators. This is not an indication of a problem. The amount of frost that forms can be affected by the size of the container, the amount of fuel being used, the humidity of the air and other operating conditions. In standard use this frost may reduce flow of gas and lower performance. If frost becomes an issue try exchanging fuel tanks to allow the first tank to warm up. You can also temporarily warm the tank up by pouring warm water over the top of the propane tank.

SWITCHING FUEL SOURCES

If you are switching fuel sources make sure to shut the generator down first and follow instructions on starting with your desired fuel source.
NOTICE
If you do not plan on operating the unit on propane do not leave the propane tank valve open. When starting on propane the engine may run rough for a few seconds while it purges gasoline in the carburetor.

POWER OUTPUT AND DEMAND

120-Volt AC devices have two different electric power demands that must be taken into consideration, namely the running power and the starting/peak power. Both are measured in Watts (typically abbreviated as "W").
The steady state continuous load is the running power demand and this is often marked on the device near its model number or serial number. Sometimes the device might only be marked with its voltage (i.e. 120 V) and current draw (e.g. 6 Amp or 6 A), in which case the running power demand in Watts can be obtained by multiplying the voltage times the current, e.g. 120 V × 20 A = 2,400 W.
Simple resistive 120-Volt AC devices such as incandescent bulbs, toasters, heaters, etc. have no extra power demand when starting, and so their starting power demands are the same as their running power demands.
More complex 120-Volt AC devices containing inductive or capacitive elements such as electric motors have a momentary extra power demand when starting, which can be up to seven times the running power demand or more. Manufacturers of such devices rarely publish this starting power demand and so it's often necessary to estimate it. A rule of thumb for devices fitted with an electric motor is to apply a starting power multiplier of 1.2 for small hand-held or portable devices and a value of 3.5 for larger stationary devices. For example, a 900 W angle grinder can be assumed to have a starting power demand of at least 1.2 × 900 W, which equals 1,080 W. Similarly, a 1,650 W air compressor can be assumed to have a starting power demand of at least 3.5 × 1,650 W, which equals 5,775 W.
To prevent overloading of the generator's 120-Volt AC system:

1. Add up the running power demand of all the 120-Volt AC devices that will be connected to the generator at one time. This total must not be greater than the generator's specified running power output.
2. Add up the running power demand again, but for the largest motor-driven device use the value of its starting power demand instead of its running power demand. This total must not be greater than the generator's specified starting power output.
3. The total running power demand of all the devices that will be connected to any one of the generator's outlets must not exceed the generator's specified running power output or 3,700 W, whichever is the lesser.

       Note: If the engine fails to start after 5 seconds, release the engine control switch. Let the generator sit idle for 15 seconds and then repeat step 10a. If the cranking speed drops after each unsuccessful attempt, then the battery may not be adequately charged. Manually start the generator in step 10b.
    2. Manual Start: Make sure the engine control switch is in the RUN position. Firmly grasp and pull the recoil handle slowly until you feel increased resistance. At this point, apply a rapid pull while pulling up and slightly away from the generator.
       

STOPPING THE GENERATOR

Normal Operation
During normal operation, use the following steps to stop START your generator:

1. Remove any connected loads from the control panel receptacles.
2. Allow the generator to run at "no load" to reduce and stabilize engine and alternator temperatures.
3. Position the engine control switch to STOP (see figure 17). If you plan to store the generator after use, turn the fuel shutoff valve to the OFF position and allow the fuel to be consumed from the carburetor.
   
4. If running on propane, make sure to close valve on propane tank.

During an Emergency
If there is an emergency and the generator must be stopped quickly, position the engine control switch to the STOP position immediately.

MAINTENANCE

BEFORE PERFORMING MAINTENANCE ON THE GENERATOR, REVIEW THE SAFETY SECTION STARTING ON PAGE 5, AS WELL AS THE FOLLOWING SAFETY MESSAGES.

Avoid accidentally starting the generator during maintenance by removing the spark plug boot from the spark plug. For electric start generators, also disconnect the battery cables from the battery (disconnect the black negative (-) cable first) and place the cables away from the battery posts to avoid arcing.
Allow hot components to cool to the touch prior to performing any maintenance procedure.
Internal pressure can build in the engine crankcase while the engine is running. Removing the oil fill plug/ dipstick while the engine is hot can cause extremely hot oil to spray out of the crankcase and can severely burn skin. Allow engine oil to cool for several minutes before removing the oil fill plug/dipstick.
Always perform maintenance in a wellventilated area. Gasoline fuel and fuel vapors are extremely flammable and can ignite under certain conditions.

MAINTENANCE SCHEDULE

Failure to perform periodic maintenance or not following maintenance procedures can cause the generator to malfunction and could result in death or serious injury.
NOTICE
Periodic maintenance intervals vary depending on generator operating conditions. Operating the generator under severe conditions, such as sustained high-load, high-temperature, or unusually wet or dusty environments, will require more frequent periodic maintenance. The intervals listed in the maintenance schedule should be treated only as a general guideline.


Avoid skin contact with engine oil or gasoline. Prolonged skin contact with engine oil or gasoline can be harmful. Frequent and prolonged contact with engine oil may cause skin cancer. Take protective measures and wear protective clothing and equipment. Wash all exposed skin with soap and water.
Following the maintenance schedule is important to keep the generator in good operating condition. The following is a summary of maintenance items by periodic maintenance intervals.

STORAGE

STORING GENERATOR

Never store a generator with fuel in the tank indoors or in a poorly ventilated area where the fumes can come in contact with an ignition source such as a: 1) pilot light of a stove, water heater, clothes dryer or any other gas appliance; or 2) spark from an electric appliance.
NOTICE
Gasoline stored for as little as 60 days can go bad, causing gum, varnish and corrosive buildup in fuel lines, fuel passages and the engine. This corrosive buildup restricts the flow of fuel, preventing an engine from starting after a prolonged storage period.
Proper care should be taken to prepare the generator for any storage.

1. Make sure the Engine Switch is switched to STOP.
2. Disconnect the battery.
3. Clean the generator as outlined in Cleaning the Generator.
4. Drain all gasoline from the fuel tank as best as possible.
5. With the fuel shut off valve open, start the engine and allow the generator to run until all the remaining gasoline in the fuel lines and carburetor is consumed and the engine shuts off.
6. Close the fuel shut off valve.
7. Change the oil (see Changing Engine Oil).
8. Remove the spark plug (see Spark Plug Maintenance) and place about 1 tablespoon of oil in the spark plug opening. While placing a clean rag over the spark plug opening, slowly pull there coil handle to allow the engine to turn over several times. This will distribute the oil and protect the cylinder wall from corroding during storage.
9. Replace the spark plug (see Spark Plug Maintenance).
10. Move the generator to a clean, dry place for storage.

TROUBLESHOOTING

Before attempting to service or troubleshoot the generator, the owner or service technician must first read the owner's manual and understand and follow all safety instructions. Failure to follow all instructions may result in conditions that can lead to voiding of the EPA certification or product warranty, serious personal injury, property damage or even death.
