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.

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 6 feet (1.8 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.
Do not operate a device plugged into the USB ports. Prolonged exposure to engine exhaust can cause serious injury or death. While charging a device do not place on the exhaust side of the generator. Extreme heat caused by exhaust can damage the device, and cause a potential fire hazard.
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.

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 determined 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.

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.

High Altitude DF Regulator Part Number: 140560

Note: You must purchase the Dual Fuel Regulator along with carburetor kit on the WGen3600DF

POWERCORD

Using Extension Cords

Westinghouse Portable Power 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 WCG25 power cord is connected to the generator at the 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.

Figure 6 - WCG25 Extension Cord

ADDING / CHECKING ENGINE FLUIDS AND FUEL

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

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:

• Level of Engine oil
• Level of gasoline in the fuel tank
• Secured connection to an undamaged LPG tank

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.

PROGRAMMING THE GENERATOR FOR REMOTE START

   Figure 7 - Maximum Gasoline Fill Level
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 THE 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

Use only standard 20 or 30 pound capacity LPG tanks with 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.

BEFORE STARTING THE GENERATOR

BEFORE STARTING THE GENERATOR, REVIEW SAFETY SECTION.

Before attempting to start the generator, verify the following:

• The engine is filled with engine oil. See Checking Engine Oil.
• The generator is situated in a proper location (Location Selection).
• The generator is on a dry surface (Weather and Dry Surface).
• All loads are disconnected from the generator (No Connected Loads).
• The generator is properly grounded the Generator.
• Propane connection is secure with no leaks or damage. See Connecting LPG Tank.

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.

MAINTENANCE

BEFORE PERFORMING MAINTENANCE ON THE GENERATOR, REVIEW THE SAFETY SECTION, 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.

CHECKING AND ADJUSTING VALVE LASH

Checking and adjusting valve lash 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) of the compression stroke. Looking through the spark plug hole, the piston should be at the top.
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 push rod and check for clearance (see Figure 25). See Table 2 for valve lash specifications

      Bolt Torque	8-12N.m	8-12N.m

6. If an adjustment is required, hold the adjusting nut and loosen the jam nut.
7. Turn the adjusting nut to obtain the correct valve lash. When the valve lash is correct, hold the ad- justing nut and tighten the jam nut to 106 in-lb (12 N•m).
8. Recheck the valve lash after tightening the jam nut.
9. Perform this procedure for both the intake and exhaust valves.
10. Install the rocker arm cover, gasket and spark plug.

BATTERY SERVICE

To ensure the battery remains charged, the generator should be started every 2 to 3 months and run for a minimum of 15 minutes or a charger should be plugged into the generator and the generator should be charged overnight. Make sure the engine control switch is in the "RUN" position when charging. Plug the cord from the charger into the charging port on the generator. Plug the charger into a 110/120-volt AC outlet.

CLEANING THE GENERATOR

It is important to inspect and clean the generator before every use.

Clean All Engine Air Inlet and Outlet Ports

Make sure all engine air inlet and outlet ports are clean of any dirt and debris to ensure the engine does not run hot.

Clean All Engine Cooling Fins

Use a damp rag and a brush to loosen and remove all dirt on or around the engine's cooling fins.

Clean All Alternator Cooling Air Inlets and Exhaust Ports

Make sure the cooling air inlets and exhaust ports of the alternator are free of any debris and ob- structions. Use a vacuum cleaner to remove dirt and debris stuck in the cooling air inlets and exhaust ports.

General Cleaning of the Generator

Use a damp rag to clean all remaining surfaces.

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: pilot light of a stove, water heater, clothes dryer or any other gas appliance; or 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 so the generator does not draw power from battery.
2. Clean the generator as outlined in Cleaning the Generator.
3. Drain all gasoline from the fuel tank as best as possible.
4. 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. If you used propane the last time you ran the generator: start the unit up with propane then shut off the propane tank valve allowing the engine to use up all the remanding propane in the carburetor before it shuts off.
5. Close the fuel shut off valve.
6. Change the oil (see Changing Engine Oil).
7. 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.
8. Replace the spark plug (see Spark Plug Maintenance).
9. 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.
PROBLEM	POTENTIAL CAUSE	SOLUTION
Engine is running, but no electrical output	Circuit breakers are tripped.	Reset the circuit breakers and check for overload condition.
	The power cord's plug connector is not fully engaged in the generator's outlet.	Verify plug connector is firmly engaged in the generator's outlet.
	Faulty or defective power cord	Replace power cord.
	Faulty or defective electrical appliance	Try connecting a known good appliance to verify the generator is producing electrical power.
	If trying 1-4 above does not solve the problem, the cause might be the generator has a fault.	Take the generator to your nearest authorized service dealer.
Engine run erratic; does not hold a steady RPM.	Dirty air filter	Clean the air filter (see pages 25-26).
	Applied loads maybe cycling on and off	As applied loads cycle, changes in engine speed may occur; this is a normal condition.
	If trying 1-2 above does not solve the problem, the cause might be a fault in the generator	Take the generator to your nearest authorized service dealer.
Generator suddenly stops running.	Generator is out of fuel.	Check fuel level. Add fuel if necessary.
	The low oil shut down switch has stopped the engine.	Check oil level and add oil if necessary.
	Too much load	Restart the generator and reduce the load.
	If trying 1-3 above does not solve the problem, the cause might be a fault in the generator.	Take the generator to your nearest authorized service dealer.
Engine will not start or remain running while trying to start.	Fuel shutoff valve is in the OFF position.	Move the fuel shut off valve to the ON position (see Figure 9).
	Generator is out of gasoline.	Add gasoline to the generator.
	Fuel flow is obstructed.	Inspect and clean fuel delivery passages.
	Starting battery may have insufficient charge	On electric start models only. Check battery output and charge battery as necessary.
	Dirty air filter	Check and clean the air filter.
	Low oil level shut down switch is preventing the unit from starting.	Check oil level and add oil if necessary.
	Spark plug boot is not fully engaged with the spark plug tip.	Firmly push down on the spark plug boot to ensure the boot is fully engaged
	Spark plug is faulty.	Remove and check the spark plug. Replace if faulty.
	Dirty/plugged spark arrestor	Check and clean the spark arrestor.
	Stale fuel	Drain fuel and replace with fresh fuel.
	If trying 1-10 above does not solve the problem, the cause might be the generator has a fault.	Take the generator to your nearest authorized service dealer.
Frost on the propane tank or regulator	This can be a normal occurrence caused when liquid propane changes phase to a gas. As this process occurs the fuel tank or regulator will cool and allow humid air surrounding the propane tank or regulator to condense into frost.	As this can be normal, providing all the propane fuel handling equipment is functioning normally, no remedy is needed.
	The propane tank is not equipped with a OPD (rollover protection device) and has been stored in a horizontal position allowing liquid propane to enter the downstream fuel handling equipment.	If you suspect your propane fuel tank is not equipped with a OPD device, discontinue operation immediately and replace the propane fuel tank with a propane tank equipped with a roll over protection device.
	Propane fuel tank over filled.	If you suspect your propane fuel tank has been overfilled, discontinue operation immediately and return the propane fuel tank to the place of purchase or refilling.
Propane fuel smell	Fuel regulator or fuel hose and fittings not securely sealed.	Using a soap solution check each connection and tighten as needed.
	Propane fuel regulator vent active.	The propane fuel regulator is equipped with a small vent that will allow a small amount of propane fuel vapor to escape from the regulator when the propane tank valve is opened. This can be normal providing the venting of the propane is brief. If you suspect that this is abnormal, immediately discontinue use and have the propane regulator inspected by a qualified technician.
	Residual fuel from the carburetor dispersing after operation.	Normal, no remedy is needed.
Poor performance or engine stalling on propane	Propane fuel line kinked or crushed.	Inspect propane fuel line and remove kinks or other obstructions.
	Fuel selector valve not properly positioned.	Rotate the fuel valve fully until the pointer is directly in line with the desired fuel.
	Gasoline not purged from the carburetor before switching to propane.	Turn the propane fuel tank valve to closed. Move the fuel selector valve to propane. Turn the gasoline fuel valve to off. Start the engine and allow the engine to run until the fuel has been consumed in the carburetor. Begin propane start up procedure.
