GENERATOR SAFETY WARNINGS

CARBON MONOXIDE

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.

NEVER use a generator inside homes, garages, crawl spaces, or other partially enclosed areas. Deadly levels of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply enough fresh air. ONLY use a generator outside and far away from windows, doors, and vents. These openings can pull in generator exhaust.

Even if you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the generator has been running, move to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly flammable and explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open flame can lead to explosion even if not directly in contact with gasoline.

• Do not operate near open flame, heat, or any other ignition source. Do not smoke near the generator.
• Always operate on a firm, level surface.
• Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow for expansion. Always check for spilled fuel before operating.
• If fuel spills, move the generator at least 30 feet away from the spill and wipe clean any spilled fuel before starting the engine.
• Empty fuel tank before storing or transporting the generator.

If this generator is used as a supply for a building's 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 all applicable laws and electrical codes and the National Electrical Code, NFPA 70.

PREPARATION

The following section describes the necessary steps to prepare the generator for use. If you are unsure about how to perform any of the steps please call 1-(800) 232-1195 M-F 8-5 CST for customer service. Failure to perform these steps properly can damage the generator or shorten its life.

STEP 1 - ADD / CHECK OIL

The generator is shipped without oil. User must add the proper amount of oil before operating the generator for the first time. The oil capacity of the engine crankcase is 17.1 fl. oz. (0.5 L).

ENGINE OIL RECOMMENDATIONS

Select good quality detergent oil bearing the American Petroleum Institute (API) service classifications SJ, SL, or SM (synthetic oils may be used). Select the SAE viscosity grade of oil that matches the expected operating temperature.

Fig. 1

• 30W Engine Oil
  Temperatures above 40°F
• 10W-30 Engine Oil
  Temperatures between 0°F - 40°F
• Synthetic 5W-30 Engine Oil
  All temperature ranges

TO ADD OIL

1. Place the generator on a level surface. Make sure the engine is OFF before adding or checking oil.
   
   Keep the generator level. Tilting the generator to assist in filling will cause oil to flow into the wrong areas of the engine and cause damage.
2. Open the oil access cover (Fig. 2 - 1), remove and wipe the oil dipstick with a clean rag. Insert the dipstick into the oil fill opening without screwing it in.
   
3. Remove the dipstick to check the oil mark on the dipstick (Fig. 3). Add oil if the oil mark covers less than one half of the dipstick.
   
4. Slowly add oil and repeat step 2 until the oil mark reaches to the top of dipstick (or when you can see the oil coming halfway up the oil fill threads). Do not overfill the crankcase.
5. Wipe clean any oil leaks and firmly tighten the dipstick.

For subsequent operation, the oil level should be checked before each use, or after every 8 hours of operation. The generator is equipped with a low-oil sensor and will not start without a sufficient amount of oil. Follow the instructions to check the oil level.

TO CHECK OIL LEVEL (before every subsequent start)

1. Place the generator on a level surface. Make sure the engine is OFF before adding or checking oil.
2. Remove and wipe the dipstick with a clean rag.
3. Insert the dipstick into the oil fill without screwing it in. Remove the dipstick to check the oil mark.
4. If the oil mark covers less than one half of the dipstick, slowly add oil until the oil mark reaches the top of the dipstick (or when you can see the oil coming halfway up the oil fill threads). See Fig. 3.

TIP: Your WEN generator is compatible with the WEN 55201 Magnetic Oil Dipstick (not included), available for purchase at wenproducts.com. The dipstick's industrial-strength magnetic tip will collect metal shavings from your generator's oil tank to help preserve the engine and extend your generator's lifespan.

STEP 2 - ADD / CHECK FUEL

RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly flammable and explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open flame can lead to explosion even if not directly in contact with gasoline.

USING YOUR GENERATOR

CALCULATING THE WATTAGE OF YOUR DEVICE(S)

Connect electrical devices running on AC current according to their wattage requirements. Calculate the total running wattage and starting wattage of the device(s) you wish to connect, and MAKE SURE that they are within the capacity of your generator and the capacity of each individual outlet

Generator Wattage Capacity	GENERATOR RUNNING (RATED) WATTS	GENERATOR STARTING (SURGE) WATTS
	1900W	2350W
	What this means: The generator can produce a maximum of 1900W on a continuous basis to supply ongoing power to your electronic devices. NOTE: Also check the rated amperage for each outlet and make sure not to overload the individual outlets.	What this means: Some devices such as box fans require short bursts of extra power in addition to the rated wattage listed by the device to start their motors. The generator can produce a maximum wattage of 2350W for a short period of time (seconds) to cover the extra starting power required by your electronic devices.
Electronic Device Wattage Calculation	Find the wattage information of each device you plan to connect. The information should be listed on the device or in its instruction manual, or you may refer to Table 2. The wattage can be calculated using this equation: Watts = Volts x Amperes
	To calculate the total running watts of your devices: + Add up the running wattages of all the device(s) you plan to connect. = The total running (rated) wattage. This wattage should NOT exceed the running wattage of 1900W. It is recommended to maintain a load at or below 1710W (90% of the rated output) to ensure steady voltage output and to prolong the generator's lifespan.	To calculate the total starting watts of your devices: + Add up the total running wattage of all the device(s) you plan to connect. + Add the single highest ADDITIONAL starting wattage out of the device(s) you plan to connect. = The total starting (surge) wattage. This wattage should NOT exceed the starting wattage of 2350W.
	If any of either of the total calculated running watts or starting watts is higher than the capacity of your generator, adjust the load until both wattage requirements are met. Otherwise you will overload the generator, and cause damage to the engine and your electrical device(s).

Table 1 - How to Calculate Wattages

The chart below serves as a reference for the estimated wattage requirements of common electrical devices. However, do not solely rely on this chart - all electronics and appliances are built differently. Always check the wattage listed on the electrical device before consulting this chart.

Table 2 - Estimated Wattages of Common Electrical Appliances

NOTE: Become familiar with the functions and capacity of each component on the control panel before connecting electrical devices. See more information about the components of the control panel. Do not overload generator or individual panel receptacles. Do not connect 50Hz or 3-phase loads to the generator.

CONNECTING ELECTRICAL DEVICES

When the rated wattage requirement of each electrical device has been determined, add these numbers to find the total rated wattage needed. If this number exceeds the rated wattage (1900W) of the generator, DO NOT connect all these devices. Select a combination of electrical devices with a total rated wattage lower than or equal to the rated wattage of the generator.

Become familiar with the markings on the control panel (Fig. 14) before connecting electrical devices. Do not connect 50Hz loads to the generator.

1. Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the speed and voltage output.
2. Make sure that all devices are turned off. Start plugging in each electric device, from the highest wattage to the lowest. Check the power indicator light (green) to ensure the generator is producing power.
3. Do not overload the generator or individual panel receptacles. If an overload occurs, the overload indication light (red) will activate. If it is flashing, turn off and unplug one load. If it is solid (not flashing), the generator will cut off power to protect itself. Unplug all electrical devices and then press the reset button to reset the entire circuit, or press the circuit breaker to reset the DC circuit. Check the total wattage of the devices and reduce the load if it exceeds the capacity of the generator. Then, plug the loads back in one by one.

NOTE: If the reset button or circuit breaker does not reset, wait several minutes and try again. If problem still persists, please call 1-(800) 232-1195 M-F 8-5 CST.

NOTE: The NEMA 5-20 receptacles are capable of connecting devices up to 20A only when two generators are parallel connected. When operating a single generator, do not exceed 15.8A (1900 running watts) on this receptacle.

Table 3 - Power Cord Requirement Guide

Generator should only be connected to electrical devices, either directly or with an extension cord. NEVER CONNECT TO A BUILDING ELECTRICAL SYSTEM without a qualified electrician and connected to a transfer switch as a separately derived system. Such connections must comply with local electrical laws and codes. Failure to comply can create a back-feed, which may result in serious injury or death to utility workers.

NOTE: For power outages, permanently installed, stationary generators are better suited for providing backup power to your home. Even a properly connected portable generator can become overloaded. This may result in overheating or stressing the machine's components, possibly leading to generator failure.

STOPPING YOUR GENERATOR

SHUTTING OFF THE GENERATOR

1. Turn off all electrical devices and then unplug the devices from the generator.
   
   Unplugging running devices can cause damage to the generator. Never stop the engine with electrical devices connected and running.
2. Allow generator to run at no load for a few minutes to stabilize internal temperatures.
3. Turn the engine switch to the FUEL OFF position (Fig. 15). This feature will burn off the remaining fuel in the carburetor, helping to combat fuel degradation and prolong engine life. You may also choose to shut off the engine quickly (e.g. for refueling, moving the generator, etc.) by turning the engine switch to the OFF position (Fig. 16), but this option will let fuel remain in the carburetor. Be sure to drain the carburetor after use to prolong engine life.
   
4. Close the vacuum relief valve (Fig. 17) on the top of the fuel cap by rotating it counterclockwise to the OFF position.
   

Allow the generator to cool for several minutes before touching areas that become hot during use.

Allowing gasoline to sit in the fuel tank for long periods of time can make it difficult to start the generator in the future. Never store the generator for extended periods of time (over 2 months) with fuel in the fuel tank. Refer to "Storing the Generator".

MAINTENANCE

Proper routine maintenance of the generator will help prolong the life of the machine. Please perform maintenance checks and operations according to the schedule in Table 4.

Never perform maintenance operations while the generator is running. Before maintaining or servicing the generator, turn OFF the generator, disconnect all devices and allow the generator to cool down.

If there are any questions about the maintenance procedures listed in this manual, please call 1-(800) 232-1195 M-F 8-5 CST or email techsupport@wenproducts.com.

Table 4 - Recommended Maintenance Schedule

GENERATOR MAINTENANCE TIPS:

• Drain your carburetor after each use and before storage to prevent it from clogging.
• Do not store the generator with fuel inside the tank for more than 2 months - the fuel will go bad.
• Run the generator for at least 15 minutes every month to maximize its lifespan.

CLEANING THE GENERATOR

Keep the generator clean to prevent improper operation or machine damage from dirt and debris. Inspect all ventilation openings on the generator. These openings must be kept clean and unobstructed. If the generator becomes dirty, use a damp cloth to wipe exterior surfaces. Use a soft bristle brush to loosen dirt and oil and use a vacuum to pick up loose dirt. Use low pressure air (not to exceed 25 PSI) to blow away dirt.

Never clean the generator when it is running! Never clean with a bucket of water or a hose. Water can get inside the working parts of the generator and cause corrosion or a short circuit.

NOTE: Failure to properly maintain the generator will void the warranty.

Make sure generator is shut off before performing any inspection or maintenance procedures.

CHECKING / ADDING OIL

Check the oil level of the generator according to the Recommended Maintenance Schedule in Table 4. The oil level should be checked before each use or every 8 hours of operation. The oil capacity of the generator engine is 17.1 fl. ounces. Add oil when the oil level is low.

For proper type and weight of oil refer to "Add / Check Oil" section. The generator is equipped with an automatic shutoff to protect it from running on low oil. To check the oil level:

1. Make sure the generator is on a level surface. Do not tilt the generator to assist in filling, as oil will flow into engine areas and cause damage. Keep generator level!
2. Open the oil access cover (Fig. 18 - 1). Remove the dipstick (Fig. 19) and wipe it with a clean rag.
   
3. Insert the dipstick into the oil fill opening without screwing in. Remove the dipstick to check the oil mark. Add oil if the oil mark covers less than one half of the dipstick.
4. Using a funnel or appropriate dispenser, slowly add more oil. Repeat step 3 until the oil mark reaches the top of the dipstick (and you can see oil coming up the threads of the oil fill). Do not over fill the crankcase.
5. Reinstall dipstick and wipe clean any spill oil with a rag.

DRAINING / CHANGING THE OIL

Change the oil according to the Recommended Maintenance Schedule in Table 4. Change the oil more often if operating under heavy load or high ambient temperatures. It is also necessary to drain the oil from the crankcase if it has become contaminated with water or dirt. Changing the oil when the engine is warm allows for complete drainage. Drain the oil from the generator according to the following steps.

1. Place generator on an elevated platform such as table or desk. Prepare a container underneath the oil fill to catch the oil as it drains.
2. Open the oil access cover. Remove the dipstick and tilt the generator towards you to allow the oil to drain from the engine completely.
3. Reinstall the oil dipstick and tighten it securely. Wipe clean any oil spillage and replace the oil access cover.

NOTE: Do not dispose of used motor oil in the trash or down a drain. Please call a local recycling center or auto garage to arrange proper oil disposal.

SPARK PLUG MAINTENANCE

The spark plug is important for proper engine operation. A good spark plug should be intact, free of deposits, and properly gapped. Refer to Recommended Maintenance Schedule in Table 4 for for instructions on maintaining. To inspect the spark plug:

1. Open the spark plug access cover (Fig. 20 - 1).
   
2. Pull up to remove the black plastic spark plug boot. Be careful not to tear any insulation or wire.
3. Use a spark plug wrench to unscrew and remove the spark plug from the engine.
4. Visually inspect the spark plug for cracks or excessive electrode wear. If the electrodes are worn or burned, or porcelain is cracked, replace with a NGK BP5H/Torch E5T spark plug (Part No. 56202i-102), available at wenproducts.com.
5. If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base then re-gap the spark plug.
6. Measure the plug gap with a wire gauge (Fig. 21). The gap should be 0.6 mm - 0.8 mm. Carefully adjust the gap if necessary.
   
7. Screw the spark plug back into the spark plug hole by hand. After the spark plug is properly seated, use the spark plug wrench to tighten it.
   NOTE: The recommended tightening of the spark plug is 1/2 to 3/4 of a turn after the spark plug gasket contacts the spark plug hole, or 11.1-14.7 ft-lbs (15 - 20 Nm). Do not over-tighten the spark plug.
8. Reinstall the spark plug boot over the spark plug.
9. Reinstall the spark plug access cover.

AIR FILTER MAINTENANCE

Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally check that the air filter is free of excessive dirt. The air filter should be checked every 50 hours of use. Refer to Recommended Maintenance Schedule in Table 4.

1. Remove the oil access panel. Unscrew the four Phillips-head screws and remove the side panel (Fig. 22 - 1).
   
2. Open the air filter cover (Fig. 23 - 1), and remove the foam air filter element from the casing.
   
3. Check and clean the foam air filter element. Wash the filter element in warm soapy water. Squeeze it thoroughly dry in a clean cloth. Saturate the element in clean engine oil and squeeze off excess oil in a clean absorbent cloth. A small amount of oil in the element is normal and necessary for the engine to work properly. If the element is damaged, replace it with a new one (part. no. 56202i-163, available at wenproducts.com).
4. Reinstall the air filter element and close the air filter cover. Close the air filter cover. Replace the side cover and secure it with the screws. Reinstall the oil access panel.

Running the engine with a dirty, damaged, or missing air filter element will result in possible danger and cause the engine to wear out prematurely.

DRAINING THE CARBURETOR

Drain the carburetor after every use and before storing the generator (refer to Table 4). Draining the carburetor can help prevent build-up and blockages caused by stagnant fuel inside of the carburetor.

1. Prepare an approved gasoline storage container.
2. Remove the oil access panel. Unscrew the four Phillips-head screws and remove the side panel (Fig. 22 - 1).
3. Open up the carburetor drain screw (Fig. 24) with a Phillips screwdriver and drain out any gasoline that has built up inside the carburetor.
   
4. Once the fuel has drained, tighten the drain screw with the screwdriver.
   NOTE: Make sure to drain your carburetor before storing the generator for long periods of time.
5. Replace the side panel and secure it with the screws. Reinstall the oil access panel.

SPARK ARRESTOR MAINTENANCE

It is recommended to inspect and clean the spark arrestor (Fig. 25 - 2) every 100 hours of operation.

1. The spark arrestor is located outside the muffler, which gets very hot during operation. Allow the engine to cool completely before servicing the spark arrestor.
2. Unscrew the six Phillips head screws and remove the muffler cover (Fig. 22 - 1).
3. Remove screw that holds spark arrestor to muffler (Fig. 25 - 1).
4. Remove the spark arrestor screen.
5. Carefully clean and remove the carbon deposits from the spark arrestor screen with a wire brush. Replace the spark arrestor if it is damaged (part no. 56202i-040, available for purchase at wenproducts.com).
6. Reinstall the spark arrestor in the muffler and secure it in place with the screw.
7. Replace the muffler cover and secure it with the six screws.

DRAINING THE FUEL TANK

1. Prepare an approved gasoline-storage container. Make sure the vacuum-relief valve atop the gas cap is open. Make sure the engine switch is turned to OFF.
2. Remove the side panel to access the carburetor, as instructed on the previous page.
3. Open the carburetor drain screw and turn the engine switch to ON. This will allow gasoline to drain from the gas tank through the carburetor.
   NOTE: it may take a few hours for your tank to drain completely, depending on the amount of gasoline in the tank.
4. Once the gasoline has drained fully, close the carburetor drain screw, turn the engine switch to OFF, and close the vacuum-relief valve.

Running the engine with a dirty, damaged, or missing air filter will result in possible danger and cause the engine to wear out prematurely.

TRANSPORTATION & STORAGE

TRANSPORTING THE GENERATOR

To prevent fuel spillage when transporting, be sure to perform the following:

1. Tighten the fuel cap and turn the fuel valve to the OFF position.
2. Flip the engine switch to the OFF position.
3. Drain the fuel tank if possible. Refer to "Draining the Fuel Tank."
4. Keep the generator upright. Never place the generator on its side or upside down - doing so could damage the internal components of the generator and make it difficult to start.

Avoid direct sunlight inside a vehicle. If the generator is left in an enclosed vehicle for many hours, the high temperature could cause the fuel to vaporize and result in a possible explosion.

STORING THE GENERATOR

Shut off the generator and allow the unit to cool to room temperature before storing it. NEVER place any type of storage cover on the generator while it is still hot. Do not obstruct any ventilation openings.

Follow the procedures below for properly storing your generator. We highly recommend running your generator once a month for 20 to 30 minutes. Plug in a small load in to ensure there is proper power output.

For Short Periods (30 to 60 Days):

• Drain the carburetor. Refer to "Draining the Carburetor."
• Add fuel stabilizer: Follow the suggested portions and instructions of your preferred stabilizer. Run the engine for 15 to 20 minutes, allowing the fuel stabilizer to mix with the gasoline and circulate through the carburetor, and then top off with fuel. Filling the fuel tank full reduces the amount of air in the tank and helps fight deterioration of fuel.

For Extended Periods (Over 60 Days):

• Drain the fuel tank and carburetor (see "Draining the Fuel Tank"). Never store generator with fuel in the tank for more than two months.
• Change the engine oil (see "CHANGING OIL").

Store the generator upright in a cool and dry location, away from sources of heat, open flames, sparks or pilot lights.
