TESTING POLICY
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.
Rated output of 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.
OPM-139 4 REV B
INTRODUCTION
INTENDED USES
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 air flow.
RESTRICTED USES
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 air flow 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.
REV B 5 OPM-139
UNIT CAPABILITIES
CAUTION: EQUIPMENT DAMAGE
Running the generator set under these conditions may result in damage to the generator stator as well as the motor winding.
GENERATOR CONNECTIONS
WL12000HE: 120 Volt and 240 Volt receptacles are provided for connection to various loads. The diagram below represents this 10,800 watt (rated output) generator.
A & B represent the 120 volt output legs of this generator.
Up to 5400 watts at 120 volts (45 Amps) can be drawn from the receptacles attached to either A or B output legs.
This generator is capable of producing 45 Amps of 240 volt current at C. Check the appliance or tool nameplates for the current and voltage to insure compatibility. Remember that power taken from C reduces the power available at equally both A and B and vice versa.
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 difficulty is experienced in starting motors, turn all other electrical loads off and if possible reduce the load on the electric motor.
STARTING ELECTRIC MOTORS
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 take about the same amount of current to run them whether they are Repulsion
Induction (RI), Capacitor (Cap), or Split-Phase (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 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.

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.
OPM-139
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 old fuel from the engine and replace with fresh fuel before attempting to start.
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.
See the engine manual for special instruction for operating this unit at over 5000 feet.
BATTERY INSTALLATION
BATTERY CHARGING
This engine generator set is shipped with a battery tie down kit for customer installation. This kit consists of a battery tie down and hardware for installation of the customer supplied battery on the unit.
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.
OPTIONAL DOLLY KIT
An optional 4-wheel dolly kit is available for this generator.
The dolly kit comes with instructions and parts list.
CAUTION: EQUIPMENT DAMAGE
Be sure to check the wheels properly before operating the generator. Ensure the brake has been applied. Allowing the unit to move will cause damage to the unit, drop cords or loads.
If you intend to use the power plant’s electric start system, you will need to purchase and install a battery to operate it.
WARNING: EQUIPMENT DAMAGE
The battery positive (+) cable is shipped with a plastic protective cap. When starting manually, this protective cap must remain in place to avoid possible damage to the engine electrical system and/or generator end.
A 12 Volt battery, BCI group U1 rated at 275 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.
CAUTION: EQUIPMENT DAMAGE
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 an 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.

OPERATING SPEED
The engine-generator must be run at the correct speed in order to produce the proper electrical voltage and frequency.
CAUTION: EQUIPMENT DAMAGE
SPEED ADJUSTMENTS SHOULD ONLY BE MADE BY
A QUALIFIED SERVICE TECH. Whenever making any speed adjustments, check the unit with a voltmeter and a frequency meter or a tachometer and be sure the voltage and speed are correct.
CAUTION: EQUIPMENT DAMAGE
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.
Lower 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 appliances being used.
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 correct RPM is not maintained. See Load vs. Output chart.
Output voltage should be checked periodically to ensure continued proper operation of the generating plant and appliances. If the generator is not equipped with a voltmeter, it can be checked with a portable meter.
Although individual units and models vary slightly, the normal voltage and frequency of the engine-generator described in this manual are approximately as follows, under varying loads:

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 charged. If the generator is being run continuously on a very light load, it is often advisable to lower the operating speed slightly.

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.
WARNING: PERSONAL DANGER:
Operating any engine driven generator without proper air flow 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.
STANDARD PORTABLE GENERATOR
APPLYING THE LOADS
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.
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.
VEHICLE-MOUNTED GENERATOR
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.
PERMANENTLY INSTALLED
GENERATORS
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within in the generator and receptacle nameplate rating. Overloading may cause damage to the generator and/or the loads.
This WINCO portable generator ships with a 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.
Most electric tools and appliances will have the 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 receptacles amperage rating is not exceeded.
WIRING
Plug your tools such as drills, saws, blowers, sump pump, 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/local codes and regulations. Check with local authorities before proceeding.
WARNING: PERSONAL DANGER
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.
REV B 11
1. These engine-generator sets are designed for portable
heavy duty commercial use. Receptacles are provided on
the control panel to permit 120 and 240 Volt portable
OPM-139
appliances and tools to be plugged directly into them.
Please note that the 3-wire 240 Volt receptacle(s) on
these units are designed to power only 240 Volt tools.
There are two hot leads and a ground wire, but no
neutral connection, in the 3-wire 240Volt receptacle. A
4-wire receptacle (two hot, one ground, and one
neutral) 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 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, 4-wire twist-lock plug (14-60P).
NOTE: Never attempt to use the 240 Volt 3-wire receptacle to wire into a building. This is a GFCI circuit and is designed for 240 Volt output only. It has no neutral connection. If you attempt to draw
120 Volt from this receptacle, the GFCI breaker will trip.
2. If the generator set is connected to an existing
distribution system, a fully isolated manual transfer switch
must be installed. The transfer switch prevents damage to
the generator and the other circuit components if main
line 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.
CAUTION: EQUIPMENT DAMAGE
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.

YOURGEN
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 normal operation range.

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.
RPM -
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.
CAUTION: EQUIPMENT DAMAGE
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 correct RPM is not maintained. See Load vs. Output chart.
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 damaging the engine.
CAUTION: EQUIPMENT DAMAGE
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 continued proper operation of the generating plant and appliances.

120 Volt and 120/240 Volt receptacles are provided for connection to various loads.
The diagram below represents this 10,800 watt (rated output) generator. A & B represent the 120 volt output legs of this generator. Up to 5400 watts at 120 volts (45 Amps) can be drawn from the receptacles attached to either A or B output legs. This generator is capable of producing
45 Amps of 240 volt current at C. Check the appliance or tool nameplates for the current and voltage to insure compatibility. Remember that power taken from C reduces the power available at equally both A and B and vice versa.
The battery has a 10 year lifetime, in the event you need to change the battery, follow these instructions:
The battery is located in the control box near potentially live
AC terminals. To prevent electrocution while changing the battery disable the unit by disconnecting the main battery, spark plug wire and then open the receptacle panel. Locate the backside of the YourGen meter. Gently pry the back plate off using the slot located on top.
Once open, the battery will be located at the top. Using a needle nose plier, carefully pull out the battery.

Change Oil Warning -
After the first 50 hours, the engine oil should be changed.
The YourGen meter will light up the oil icon ( ) and the word ‘change’ will flash. Once the oil has been changed, press and hold the cycle button for approximately 5 seconds until the warning has been removed from the display to reset the warning. The meter will then remind you of oil changes on the appropriate schedule for your generator. It is important to remember that the engine manufacturer recommends changing the oil on a calendar schedule even if the total number of operational hours have not been reached. Certain operating environments may also require more frequent oil changes.

GENERATOR CARE
Proper care and maintenance of the generator is necessary to ensure a long trouble free life.
EXERCISING THE GENERATOR
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 enginegenerator set will also ensure that the set is operating properly should it be needed in an emergency.
GENERATOR MAINTENANCE
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
and destructive to the equipment.
CLEANING
Remove dirt and debris with a cloth or brush. DO NOT use 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 fly wheel. 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.
