Before any generator is shipped from the factory, it is fully checked for performance. The generator is loaded to its full capacity, and the voltage, current, and frequency are carefully checked.
The rated output of the generator is based on engineering tests of typical units, and is subject to, and limited by, the temperature, altitude, fuel, and other conditions specified by the manufacturer of applicable engines.
This engine generator set has been designed primarily for portable heavy-duty commercial use. Both 120 volt and 240-volt receptacles are provided in the control panel to plug in your loads (lights, portable tools, and small appliances). These units are dual wound generators, therefore the 120-volt loads must be equally split with 1/2 of the rated capacity available on each of the two 120 volt circuits. This portable unit requires large quantities of fresh air for cooling the engine and generator. For safety, long life, and adequate performance, these units should never be run in small compartments without positive fresh airflow.
DO NOT remove from the cradle assembly. Removal of the generator from the cradle assembly may cause excessive vibration and damage to the engine-generator set.
DO NOT operate and/or store the unit outside during inclement weather without adequate protection from the elements. Failure to do so will damage the unit.
DO NOT install and operate this generator in a small compartment., i.e. generator compartments of vehicles, motor homes, or travel trailers. These compartments will not allow enough free flow of fresh air to reach the engine-generator set for cooling and will cause the unit to overheat, damaging both the engine and generator. Small compartments will also develop hot spots where there is very little airflow and may cause a fire.
PLEASE NOTE There are 3rd party companies making enclosures for generators that have been properly engineered. The use of these 3rd party enclosures is acceptable as long as they have been certified and meet current code.
DO NOT attempt to operate at 50 cycles. These units are designed and governed to operate at 60 cycles only.


WL22000VE: 120 Volt and 240 Volt receptacles are provided for connection to various loads. The following diagram represents this 19,000 watt (rated output) generator. A & B represent the 120-volt output legs of this generator. Up to 9500 watts at 120 volts (79 Amps) can be drawn from the receptacles attached to either A or B output legs. This generator is capable of producing 79 Amps of 240-volt current at C. Check the appliance or tool nameplates for the current and voltage to ensure compatibility. Remember that power taken from C reduces the power available equally at both A and B and vice versa.

WINCO GENERATOR WL22000VE-B Generator User Manual  & troubleshooting 5


Electric motors require much more current (amps) to start them than to run them. Some motors, particularly low-cost split-phase motors, are very hard to start and require 5 to 7 times as much starting current as running current. Capacitor motors are easier to start and usually require 2 to 4 times as much starting current as running current. Repulsion Induction motors are the easiest to start and require only 1 1/2 to 2 1/2 times as much starting as running current. Most fractional horsepower motors (746 Watts or less) take about the same amount of current to run them whether they are Repulsion Induction (RI), Capacitor (Cap), or SplitPhase (SP) type.
If the electric motor is connected to a hard starting load such as an air compressor, it will require more starting current. If it is connected to a light load, or no load such as a power saw, it will require less starting current. The exact requirement will also vary with the brand or design of the motor.
Self-exciting generators respond to severe overloading differently than utility power. When overloaded, the engine is not able to supply enough power to bring the electric motor up to operating speed. The generator responds with a high initial starting current, but the engine speed drops sharply. The overload may stall the engine. If allowed to operate at very low speeds, the electric motor starting winding will burn out in a short time. The generator winding might also be damaged.

Running the generator set under these conditions may result in damage to the generator stator as well as the motor winding.
The heavy surge of current required for starting motors is required for only an instant. The generator will not be damaged if it can bring the motor up to speed in a few seconds of time. If the difficulty is experienced in starting OPM-140/E motors, turn all other electrical loads off and if possible reduce the load on the electric motor.



THIS UNIT HAS BEEN SHIPPED WITH OIL. Failure to maintain the engine oil at the proper level will result in serious engine damage.
When you unpack your engine-generator set be sure to remove all the information sheets and manuals from the carton.

  1. As you receive your unit, it is critical to check it for any damage. If any damage is noted, it is always easiest to refuse the shipment and let WINCO take care of the freight claim. If you sign for the unit, the transfer of the ownership requires that you file the freight claim
  2. Before proceeding with the preparations of your new generator for operation, take a couple of minutes to ensure the unit you have received is the correct model and review the specification pages in this manual to ensure that this unit meets your job requirements.

Before starting the engine, check the oil level. This unit has been shipped with oil. The recommended grade oil and quantity of oil required is listed in the engine operator’s manual and under the service tab in this manual. This unit was shipped with most of the oil removed. The engine normally holds 73.6 ounces (2.3 quarts) of oil. Since there is some trapped in the engine when filling the crankcase the first time, use the dipstick to ensure that you do not overfill the crankcase. The full oil level mark on the dipstick is depicted in the following image.

WINCO GENERATOR WL22000VE-B Generator User Manual  & troubleshooting 6

Oil is added to the engine by removing the oil cap and adding oil at this point. After filling the crankcase to the proper level, be sure you properly tighten the oil fill cap.
NOTE: This engine generator must be on a level surface before you check or add oil to the system. The necessity of using the correct oil and keeping the crankcase full cannot be overemphasized. Engine failures resulting from inadequate or improper lubricant are considered abuse and not covered by the generator or engine manufacturer’s warranty.

Outdoor temperatures determine the proper oil viscosity for the engines. Winco recommends our 5W-30 fully synthetic oil to give you excellent protection in cold temperatures while maintaining excellent performance in warmer weather.

WINCO GENERATOR WL22000VE-B Generator User Manual  & troubleshooting 7

A SAE 30 – Below 40 °F (4 °C) the use of SAE 30 will result in hard starting.
B 10W-30 – Above 80 °F (27 °C) the use of 10W-30 may cause increased oil consumption Check oil levels more frequently.
C Synthetic 5W-30
D 5W-30

This generator is equipped standard with the Briggs & Stratton low oil pressure shutdown system. The low oil shutdown system is designed to prevent severe damage caused by an insufficient amount of oil in the crankcase. However, if the unit is repeatedly allowed to shut down on low oil pressure, progressive damage will be done to the engine, shortening the engine’s life. The engine switch will remain in the “ON” position when the unit is shut down by the low oil pressure system.

Allowing the engine to shut down repeatedly on low oil levels may cause excessive wear which can be cumulative.

When using gasoline, always use fresh, clean, unleaded fuel. The engine is certified to operate on unleaded gasoline with a minimum octane rating of 87 or higher. Gasoline containing no more the 10% ethanol is acceptable.
Do not use unapproved gasoline, such as E15 or E85. Do not mix oil in the gasoline. The use of unapproved fuels will damage the engine components and void the engine warranty.

The use of fuels with the content of ethanol greater than shown above may cause starting and/or performance problems. Always ensure that the fuel is clean and free of all impurities.
Gasoline and its fumes are VERY explosive when proper precautions are not taken.

Never use gasoline that has been stored for an extended period of time as the fuel will lose its volatile properties and you will be left with varnish residue. The varnish-like substance will clog the carburetor and will not burn properly.
The use of fuel additives, such as Sta-Bil, or an equivalent will minimize the formation of fuel gum deposits. If a unit has been out of operation for an extended period of time,it is best to drain the old fuel from the engine and replace with fresh fuel before attempting to start.
See the engine manual for special instruction for operating this unit at over 5000 feet.


This engine generator set is shipped with a bungee cord for installation of the customer-supplied battery in the unit’s battery tray.

If you intend to use the unit’s electric start system, you will need to purchase and install a battery to operate it. A 12 Volt battery, BCI group 26 rated at 500 CCA or larger is recommended for this electric start engine-generator set. Follow the battery manufacturers’ recommendations for servicing and charging prior to use. Connect the battery to the electric start system using the cables provided.

These electric start engines are NEGATIVE GROUND. Use extreme caution when connecting the battery. Connect the NEGATIVE battery terminal to GROUND. For your safety, always connect the positive battery cable to the “bat+” terminal first. Then connect the negative battery cable to the “Bat-” terminal. Make sure all connections are clean and tight. Reverse the sequence when disconnecting, disconnect the negative cable first. These engines produce enough direct current to keep the battery charged under normal operating conditions, but were not intended to be used as a battery charger.

Lead-acid batteries produce explosive hydrogen gas when charging. Keep sparks, flames, and burning cigarettes away from the battery. Ventilate the area when charging or using the battery in an enclosed space. Lead-acid batteries contain sulfuric acid, which causes severe burns. If acid contacts eyes, skin, or clothing, flush well with water. For contact with the eyes, get immediate medical attention.

Units have a small flywheel charger built into the engine flywheel assembly for recharging the starting battery. This flywheel charger generates a small AC current that passes through a diode assembly to produce DC charging current of about 1 to 3 Amps. This circuit is not designed to be used as a battery charging circuit to recharge dead batteries.

The lifting eye is shipped loose along with a bag of parts. Install the base of the lifting eye below the middle support. See diagram below.WINCO GENERATOR WL22000VE-B Generator User Manual  & troubleshooting 9

An optional 4-wheel dolly kit is available for this generator.
The dolly kit comes with instructions and a parts list.


The throttle control on these generators is preset and locked to operate at 3600 RPM (nominal) with no load speed set at 3690 RPM. Only a trained service technician should be allowed to adjust this speed setting.
This unit will not start if it is low on oil. The lubricating oil level must be at the full mark before the engine will start and run.
Always start the unit with the circuit breaker open, never start with the load applied. Always keep the battery charged, especially during cold weather operations.

  1. Check oil level, refill as needed.
  2. Turn on the fuel supply.
  3. Move the choke to the full “ON” position for starting.
    A warm engine will require less choking than a cold one.WINCO GENERATOR WL22000VE-B Generator User Manual  & troubleshooting 10
  4. Turn the key to the start position. The starter life is improved by using shorter start cycles. Do not operate the starter for more than 15 seconds during each minute. Repeat as necessary.
  5. When the engine starts, release the key and open the choke gradually.
  6. The engine should promptly come up to operating speed.

Never permit the choke to remain on after the engine has run for a short time. It is not necessary to choke the engine when it is warm. Avoid over-choking.


    A. Use the proper oil for the temperature expected.
    B. Use fresh winter-grade fuel. Winter grade gasoline is blended to improve starting. Do not use summer-grade gasoline.
    A. Use the proper oil for the temperature expected.
    B. Use only summer blended gasoline. Using gasoline leftover from winter may cause the unit to vapor lock.


  1. Move the key to the “OFF” position.
  2. Turn off the fuel supply valve.
  3. Before extended storage (over 30 days) certain precautions must be taken to ensure the fuel doesn’t deteriorate and clog the fuel system.

NOTE: The use of a fuel additive, such as Sta-Bil or equivalent will minimize the formation of gum deposits during storage. The additive may be added to gasoline in the engine’s fuel tank or to gasoline in a storage container.
A. Add the fuel stabilizer to the fuel in the tank and run for 2 minutes to circulate the stabilizer throughout the fuel system.
B. Remove the remaining fuel from the fuel tank, it must be drained into an approved container.
C. Start the engine and allow it to run until all the fuel in the carburetor and the fuel lines has been used up and the engine stops.

NOTE: Running the engine to use up the fuel in the lines and carburetor will still leave a small amount of fuel in the carburetor. It is best-extended storage practice to treat the fuel before draining.
D. While the engine is warm, drain the oil and refill with fresh oil.
E. Remove the spark plug, pour approximately 1/2 oz.
(15cc) of engine oil into the cylinder and crank slowly to distribute the oil. Replace the spark plug.
E. Clean dirt and chaff from the cylinder, cylinder head fins, blower housing, screen, and muffler areas.
F. Store in a clean and dry area.


The engine generator covered in this manual was designed for portable use. Do NOT operate indoors. The unit should be stored in a warm, dry location. Move the unit outdoors to a flat, dry location for use.
Operating any engine-driven generator without proper airflow can result in personal injury or death. DO NOT operate this unit inside a home or garage, near vents or windows, or anywhere carbon monoxide gas could accumulate.

WINCO GENERATOR WL22000VE-B Generator User Manual  & troubleshooting 11

Allow the engine to warm up for two or three minutes before applying any load. This will allow the engine to reach normal operating temperature and oil to circulate throughout the engine. A short warm-up time will permit the engine to work more efficiently when the load is applied and will reduce the wear in the engine, extending its life.
Receptacles have been provided to allow loads to be connected to the generator. The loads should be added one at a time. If a large motor is being started: or multiple motors are being started, they should be started individually and the largest should be started first.


Keep the generator load within in the generator and receptacle nameplate rating. Overloading may cause damage to the generator and/or the loads.

Most electric tools and appliances will have voltage and amperage requirements on their individual nameplates. When in doubt, consult the manufacturer or a local electrician. The nameplate amperage rating for electric motors can be misleading. See “Starting Electric Motors” in the Unit Capabilities.

These engine-generator sets are inherently self-regulating based on engine speed. The engine governor will automatically adjust itself to the load. No harm to the generator will result if it is operated with no load connected. Proper utilization of the receptacles located on the control panel is necessary to prevent damage to either the receptacles or the generator. The generator is a limited source of electrical power. Therefore, pay special attention to the receptacle and generator ratings. The nameplate rating can be obtained through a single receptacle as long as the receptacle’s amperage rating is not exceeded. OPM-140/E


Proper grounding of your generator is application dependent. Carefully evaluate your planned use of your generator to understand which grounding you require. If you are not sure what to do, contact a competent professional to assist you. The NFPA 70 250:34-35 are good technical references.
Your WINCO portable generator ships with a bonded neutral. You can safely use this generator without external grounding as long as all loads are powered through the receptacle panel.
Your WINCO portable generator ships with a bonded neutral. When mounted to a vehicle to safely distribute power it is necessary that the generator frame is bonded to the vehicle frame. The generator should only supply equipment that is cord and plug connected through receptacles mounted on the generator or the vehicle.
This WINCO portable generator ships with bonded neutral and overcurrent protection. NFPA 70 refers to this as a “separately derived system.” When connecting it to a building a transfer switch specifically designed for GFCI and bonded neutral generators is required.

Plug your tools such as drills, saws, blowers, sump pumps, and other items to be powered directly into the generator receptacles. Before plugging in all the tools and cord sets, recheck the rating of the generator set. Be sure it can handle the intended load and is compatible with the voltage, phase, and current ratings. ‘Hard wiring’ this unit directly into a temporary construction site electrical system is NOT A SIMPLE DO-IT-YOURSELF JOB. For your safety, all wiring must be done by a qualified electrician and conform to the National Electric Code and comply with all state and local codes and regulations. Check with local authorities before proceeding.
A fully isolated, double pole double throw manual transfer switch must be installed any time a generator is being connected to an existing distribution system.

  1. These engine-generator sets are designed for portable heavy-duty commercial use. Receptacles are provided on the control panel to permit 120 and 120/240 Volt portable appliances and tools to be plugged directly into them. An Anderson connector receptacle has been provided on the control panel for use in temporary power applications requiring 120/240 Volt power. Consult a licensed electrician for wiring the TemPower plug and connecting it as a temporary service.
    To connect these units directly to an un-powered, isolated construction site TemPower panel, have your electrician connect to the control panel using a 120/240 Volt, Anderson plug.
    NOTE: To use the 120/240 Volt L14-30 receptacle to wire into a building, make sure the transfer switch is compatible with GFCI protected generators.
  2. If the generator set is connected to an existing distribution system, a fully isolated manual transfer switch must be installed. The transfer switch must be compatible with GFCI protected generators. WINCO recommends Reliance manual transfer switches. The transfer switch prevents damage to the generator and the other circuit components if mainline power is restored while the generator is connected. Installing a transfer switch also permits the use of normal fusing.
  3. Many homes and construction sites are wired for at least 60 to 100 Amp entrance service, much greater than the capacity of this portable generator. When installing the generator at these sites, a secondary emergency distribution panel may have to be installed. The emergency distribution panel must be installed by a licensed electrician according to all applicable codes. The electrician will move the critical circuits to be powered during the outage to the emergency panel. Keep in mind only a limited amount of amperage is available from the generator set. Some circuit breakers may still have to be turned off to prevent an overload on the generator during the initial start-up. See the nameplate on your generator for the amperage capabilities of your unit.

Failure to properly limit and balance the load applied to the generator will cause the generator to produce low voltage and may damage the engine-generator set. It may also cause severe damage to the loads connected to the generator at that time. Improper loading of the generator set constitutes abuse and will not be covered by warranty.


The WINCO YourGen meter allows you to see useful information about your generator from the front panel by displaying RPMs, Voltage, frequency, load, hours, and maintenance reminders. It also has the ability to display warnings if any parameter gets outside of the normal operating range.WINCO GENERATOR WL22000VE-B Generator User Manual  & troubleshooting 12

Cycle Button (↵ )
During normal operation, the display will toggle through on fixed delay. If you want to see any specific item, you can press the cycle button to move it to that setting. Once the display is selected, the delay before it starts toggling is approximately 5 seconds. This button is also used to reset maintenance reminders.
The meter will display the RPMs of the engine. This number is calculated based upon frequency and is not directly measured from the engine. The engine generator must be run at the correct speed in order to produce the proper electrical voltage and frequency.

The output voltage should be checked to ensure the generator is working properly prior to connecting a load to the generator. Failure to do so could result in damage to equipment plugged into the unit and possible injury to the individual.
Operating Speed
All engines have a tendency to slow down when a load is applied. When the electrical load is connected to the generator, the engine is more heavily loaded, and as a result, the speed drops slightly. This slight decrease in speed, together with the voltage drop within the generator itself, results in a slightly lower voltage when the generator is loaded to its full capacity than when running no load. The slight variation in speed also affects the frequency of the output current. This frequency variation has no appreciable effect in the operation of motors, lights, and most appliances. However, electronic equipment and clocks will be affected if the correct RPM is not maintained. See Load vs. Output chart.
Although individual units and models vary slightly, the normal voltage and frequency of the engine-generator described in this manual are approximate as follows, under varying loads:

120V Receipt 240V Receipt
None 3690 62. 120V 240V
Half 3600 60.0 120V 240V
Full 3510 59. 120V 240V

The speed of the engine was carefully adjusted at the factory so that the generator produces the proper voltage and frequency. For normal usage, the speed setting should not be changed. If the generator is being run continuously on a very light load, it is often advisable to lower the operating speed slightly. The engine will govern itself at full speed. Intentionally overriding the governor and operating the generator at low voltage may damage both the generator and any load connected to it. Running the engine at excessively high speeds results in high voltage, which may significantly shorten the life of light bulbs and appliances being used, as well as possibly damage the engine.
SPEED ADJUSTMENTS SHOULD ONLY BE MADE BY A QUALIFIED SERVICE TECH. Whenever making any speed adjustments, check the YourGen meter and be sure the voltage and speed are correct.

Output voltage should be checked periodically to ensure the continued proper operation of the generating plant and appliances. Hz
This is the measured frequency of the generator set. See the table in the RPM section above for an explanation of voltage and frequency ranges under load.
V1 – Output voltage of Line 1 (L1 on panel) to neutral. See the Load vs. Output table for an explanation of voltage and frequency ranges under load.
V2 – Output voltage of Line 2 (L2 on panel) to neutral. See the Load vs. Output table for an explanation of voltage and frequency ranges under load.The V1-V2 Output voltage of Line 1 (L1) and Line 2 (L2). See the Load vs. Output table for an explanation of voltage and frequency ranges under load.
This displays the total running hours of the generator set. When the generator is turned off, the hours will remain displayed. The display is run on a CR2032, a ten-year battery. Once the unit is running, the battery connected to the unit will then supply the power to the YourGen meter. Load Bars – These bars indicate how much load is being used on Line 1 (L1) and Line 2 (L2).

Proper care and maintenance of the generator is necessary to ensure a long trouble-free life.


The generator should be operated every three to four weeks. It should be operated for a period of time sufficient to warm the unit up and to dry out any moisture that has accumulated in the windings. If left, this moisture can cause corrosion in the winding. Frequent operation of the engine generator set will also ensure that the set is operating properly should it be needed in an emergency.

Any major generator service, including the installation or replacement of parts, should be performed only by a qualified electrical service technician. USE ONLY FACTORY-APPROVED REPAIR PARTS. A. Bearing – The bearing used in these generators is a heavy-duty, double-sealed ball bearing. They require no maintenance or lubrication. B. Receptacles – Quality receptacles have been utilized. If a receptacle should become cracked or otherwise damaged, replace it. Using damaged or cracked receptacles can be both dangerous to the operator

Remove dirt and debris with a cloth or brush. DO NOT use a high-pressure spray to clean either the engine or the generator. The high-pressure spray could contaminate the fuel system and the generator components.

  1. Keep the air inlet screen on both the engine and generator free of any dirt or debris to ensure proper cooling. At least yearly, remove the blower housing on the engine and clean the chaff and dirt out of the engine cooling fins and flywheel. Clean more often if necessary. Failure to keep these areas clean may cause overheating and permanent damage to the unit.
  2. Periodically clean muffler area to remove all grass, dirt, and combustible debris to prevent a fire.
  3. On engine mufflers equipped with spark arresters, the spark arrester must be removed every 50 hours for cleaning and inspection. Replace if damaged.
