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.
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 17.0 fl. oz. (0.5 L).
ENGINE OIL RECOMMENDATIONS - Select good quality detergent oil bearing the American Fig. 3 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. For general use (above 40°F), we recommend using 30W engine oil.
TO ADD OIL:
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 on the next page to check the oil level.
TO CHECK OIL LEVEL (before every subsequent start):
To protect the unit from damage, the generator is equipped with a low-oil-pressure shutoff that will automatically shut down the engine when the oil level is too low. The oil level of the engine should be checked before each start to ensure that the engine crankcase contains sufficient lubricant.
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.
FUEL OPTION A: GASOLINE
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.
Use ONLY fresh (within 30 days from purchase), lead-free gasoline with a minimum of 87 octane rating. The generator performs best with ethanol-free gasoline. DO NOT use gasoline with over 10% ethanol. The capacity of the fuel tank is 1.85 US gallons (7.00 L). Do not mix oil with gasoline.
To add gasoline:
To check gas level (before every subsequent start):
FUEL OPTION B: LIQUID PETROLEUM GAS (LPG)
To connect your generator to an LPG cylinder:
NOTE: You can use Teflon (or other tape) to secure the connection of the LPG hose to your generator.
NOTE: If you would like to purchase other accessories for your dual-fuel generator, consult your local dealer of propane and propane ac- Fig. 10 cessories, I tell you what.
Always position the LPG cylinder so the connection between the tank and LPG inlet won't cause sharp bends or kinks in the hose.
Risk of burns. Contact with liquid contents of cylinder will cause freeze burns to the skin. If liquid contents contacts skin or eyes, seek immediate medical attention.
When transporting and storing, keep cylinder secured in an upright position with cylinder valve turned off. Keep cylinders ventilated and away from heat when in a vehicle.
Your generator is equipped with Auto Fuel Selection Technology. What this means is that the generator will automatically select the fuel source (LPG or gasoline) depending on availability. LPG is prioritized; this means that if a propane tank with enough LPG is connected, the generator will automatically use LPG. If no propane tank is connected, or if there is no LPG remaining in the tank, the generator will use gasoline (if there is gasoline in the fuel tank). Refer to the table below for information on how to set up your generator for a particular fuel.
Propane tank valve | Fuel Valve | |
I want to use gasoline. | Closed | Run |
I want to use LPG. | Open | Off or On* |
Table 1 – Auto Fuel Selection® chart.*It is ideal to run the generator on LPG with the fuel valve closed (OFF), but if it stays open, the generator will still run properly.
NOTE: Make sure the generator can handle the load(s) you plan to connect. The generator can provide more power when running on gasoline than on LPG. Consult the specifications table, as well as the chart "Calculating the Wattage of Your Device(s)" to ensure that your load(s) will not exceed the rated wattage for a particular fuel. See also "Switching Fuels" section for more information.
To reduce the risk of electric shock and to maximize safety, the generator should be properly grounded.
Failure to properly ground the generator increases your risk of electric shock.
NOTE: Grounding wire and grounding rods are not included with the generator. A generally acceptable grounding wire is a No. 12 AWG (American Wire Gauge) stranded copper wire. Grounding codes can vary by location. Contact a local electrician to check the area codes.
Before starting the generator, make sure you have read and performed the steps in the "Generator Preparation" section of this manual, pages 14-16. If you are unsure about how to perform any of the steps in this manual please call 1-800-232-1195 (M-F 8-5 CST) for customer service.
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 batterybackup 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.
The exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
Do not operate generator near open flame or flammable materials 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 it isn't directly in contact with gasoline. Do not smoke near the generator.
This generator produces powerful voltage, which can result in electrocution.
Do not use in rainy or wet conditions. Do not touch bare wires or receptacles (outlets). Do not allow children or non-qualified persons to operate.
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.
To maximize safety, ALWAYS ground the generator before using it. Refer to "Step 3 - Ground The Generator".
Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal decking or steel work. GFCIs are available in-line with some extension cords.
Disconnect all electrical loads from the generator before attempting to start it.
Follow the instructions on the next page to start your generator.
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 |
Gas: 3500W LPG: 3200W | Gas: 4000W LPG: 3600W | |
What this means: The generator can produce a maximum of 3500W (gas) or 3200W (LPG) 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 4000W (gas) or 3600W (LPG) 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 - Estimated Wattages of Common Electrical Appliances. 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 3500W (gas) or 3200W (LPG). It is recommended to maintain a load at or below 3150W (gas) or 2880W (LPG) (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 4000W (gas) or 3600W (LPG). | |
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). |

NOTE: Become familiar with the functions and capacity of each component on the control panel before connecting electrical devices. See for 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.
This generator is equipped with an Eco-Mode Idle Control Switch. Engaging this switch allows the system to regulate the engine speed and automatically adjust its fuel consumption to match the required load. When the electrical load changes, the generator engine will automatically speed up and slow down as needed. This reduces fuel consumption and noise levels, while extending runtime and engine's lifespan.
Keep this switch engaged ONLY when the power load requirement is less than 2400W (75% of the rated watts). Do not engage the Eco-Mode Switch when the total load is more than 2400W. The generator engine must run at full speed to supply power for anything over 2400W.
The parallel connection ports allow you to connect two WEN generators to increase the total available electrical power. The WEN Parallel Connection Kit can be purchased from wenproducts.com. Follow the instructions included with your parallel connection kit for proper installation and operation.

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.
Your generator is equipped with Auto Fuel Selection technology. To maximize your generator's lifespan, we recommend removing all loads from the generator before switching between gasoline and LPG. If this is not possible, reduce loads as much as possible in order to ensure a smooth switch. Your generator is rated to handle a higher load when running on gasoline than on LPG, so keep this in mind when planning your fuel usage.
The CO Watchdog carbon monoxide monitoring system (Fig. 16 - 1) measures the accumulation of poisonous CO gas while the generator is running. If the level of CO gas gets too high, the CO Watchdog system will automatically shut down the generator. This system is not a substitute for an indoor CO alarm.
NOTE: if the generator is oriented so that the engine exhaust is blown towards the CO sensor, the generator may shut down.
Whenever the CO Watchdog system shuts down the generator, the LED on the generator control panel (Fig. 16 - 1) will blink red for at least 5 minutes after the generator is shut down. An LED on the sensor module itself will also start blinking red. If you notice that the LED is blinking red, vacate the area immediately. Go to an open, outdoor area. Ventilate the area around the generator thoroughly before returning. Let the generator stay shut down for a few minutes before restarting the engine. This should allow
carbon monoxide to dissipate from the area. If you restart the generator and CO Watchdog detects that CO levels are still too high, it will shut down the generator again. If CO levels are low enough, the generator will run normally.
Ensure that the generator is located in an open outdoor area, with the exhaust pointing away from occupied structures, and pointing away from the prevailing winds, such that those winds do not blow engine exhaust towards the sensor module. If anyone experiences dizziness, headaches, nausea, fatigue, or other symptoms of CO poisoning, get to fresh air immediately and seek the attention of a qualified medical professional. Follow all other directions in this manual regarding the connection and disconnection of electrical devices when starting or shutting down the generator.
When starting the generator, the CO Watchdog LED on the panel may flash. This indicates that the system is running a self-test procedure, and does not indicate a problem.
If the CO Watchdog LED on the panel is yellow, a system error has occurred, or the CO sensor has reached the end of its life. Contact WEN customer service (1-800-232-1195, M – F 8 – 5 CST, or techsupport@wenproducts. com) for assistance.
When operating your generator, please note the following:
Unplugging running devices can cause damage to the generator. Never stop the engine with electrical devices connected and running.
Allow the generator to cool down 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".
Always ensure that the fuel valve and the engine switch are in the OFF position when the generator is not in use.
NOTE: If for some reason (e.g. refueling, moving the generator, etc.) you need to shut down the generator quickly, simply flip the engine switch to STOP. However, doing this will allow fuel to remain in the carburetor, and will lead to problems if the carburetor is not drained after use.
Proper routine maintenance of the generator will help prolong the life of the machine. Please perform maintenance checks and operations according to the maintenance schedule below, Table 4. If there are any questions about the maintenance procedures listed in this manual, please contact customer service at 1-800-232-1195 (M-F 8-5 CST), or email techsupport@wenproducts.com.

GENERATOR MAINTENANCE TIPS:
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.
Check the oil level before each use and every 8 hours of operation (refer, Table 4). The oil capacity of the generator engine is 17.0 fl. oz. (0.5 L). Add oil when the oil level is low. For the proper type and weight of oil refer to, Fig. 3. This is a critical step for proper engine starting. The generator is equipped with a with low-oil shut down to protect it from running without oil.
To check the oil level and/or add oil refer to "Step 1 - Add/Check Oil".
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.
Change the oil according to the Recommended Maintenance Schedule (refer to 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 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.
NOTE: We recommend draining the carburetor after every session in which gasoline was used. If you drained the carburetor previously, and only used LPG as fuel, you do not need to drain the carburetor.
Inspect and clean the air filter every 50 hours of operation (refer to Table 4). Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally check that the air filter is free of excessive dirt. Clean air filter more frequently in dirty or dusty conditions.
Running the engine with a dirty, damaged or missing air filter element can result in danger to the operator and cause the engine to wear out prematurely.
Inspect and clean the spark arrestor every 100 hours of operation (refer to, Table 4). 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.
Inspect and change the spark plug every 100 hours of operation (refer to, Table 4). The spark plug is important for proper engine operation. Check the spark plug regularly to maintain proper engine operation. A good spark plug should be intact, free of deposits, and properly gapped.
Drain and clean the fuel tank each year, or before storing the generator for longer than two months.
To prevent fuel spillage when transporting, be sure to perform the following:
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. TIP: Your WEN generator is compatible with We highly recommend running your generator once a month for the WEN 56310iC and GNC400 Generator 20 to 30 minutes. Plug in a small load in to ensure there is proper Covers (not included). They are available power output.

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 batterybackup 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.
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. The generator shall be connected to a transfer switch that switches all conductors excluding the equipment grounding conductor. The frame of the generator shall be connected to an approved grounding electrode.
