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 ow.
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 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 ow 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
ow and may cause a re.
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 certied and
meet current code.
DO NOT attempt to operate at 50 cycles. These units are designed and
governed to operate at 60 cycles only.
UNIT CAPABILITIES
GENERATOR CONNECTIONS
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 insure compatibility. Remember that power taken from C
reduces the power available equally at both A and B and vice versa.
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.
CAUTION: EQUIPMENT DAMAGE
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 difculty is experienced
in starting motors, turn all other electrical loads off and if possible
reduce the load on the electric motor.

PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
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 le 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 specication pages in this
manual to ensure that this unit meets your job requirements.
LUBRICATION
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 lling the crankcase the rst time,
use the dipstick to ensure that you do not over ll the crankcase. The
full oil level mark on the dipstick is depicted in the following image.
Oil is added to the engine by removing the oil cap and adding oil at
this point. After lling the crankcase to the proper level, be sure you
properly tighten the oil ll 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.
OIL RECOMMENDATIONS
Outdoor temperatures determine the proper oil viscosity for the
engines. Use the chart to select the best viscosity for the outdoor
temperature range expected.
OIL ALERT SYSTEM
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 insufcient amount of oil in
the crankcase. However, if the unit is repeatedly allowed to shutdown
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 shutdown by the low oil pressure system.
CAUTION: EQUIPMENT DAMAGE
Allowing the engine to shutdown repeatedly on low oil level may cause
excessive wear which can be cumulative.
GASOLINE
When using gasoline, always use fresh, clean, unleaded fuel. The
engine is certied to operate on unleaded gasoline with a minimum
octane rating of 87 or higher. Gasoline containing no more the 10%
ethanol is acceptable.
CAUTION: EQUIPMENT DAMAGE
Do not use unapproved gasolines, such as E15 or E85. Do not mix
oil in the gasoline. Use of unapproved fuels will damage the engine
components and void the engine warranty.
Use of fuels with 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.
WARNING: FIRE DANGER
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.

7REV A OPM-110
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.
See the engine manual for special instruction for operating this unit at
over 5000 feet.
BATTERY INSTALLATION
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.
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 rst. 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 rst.
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.
WARNING: PERSONAL INJURY
Lead acid batteries produce explosive hydrogen gas when charging.
Keep sparks, ames, 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, ush well with water. For
contact with the eyes, get immediate medical attention.
BATTERY CHARGING
Units have a small ywheel charger built into the engine ywheel
assembly for recharging the starting battery. This ywheel 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.
LIFTING EYE INSTALLATION
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.

INITIAL START UP
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.
NOTICE: ENGINE START LOCKOUT
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.
BASIC OPERATION
CAUTION: EQUIPMENT DAMAGE:
Always start the unit with the circuit breaker open, never start with the
load applied. Always keep the battery charged, especially during cold
weather operation.
1. Check oil level, rell 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.
4. Turn the key to the start position. The starter life is improved
by using shorter start cycles. Do not operate the starter 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.
CAUTION: EQUIPMENT DAMAGE
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.
STARTING HINTS
1. COLD WEATHER
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.
2. HOT WEATHER
A. Use the proper oil for the temperature expected.
B. Use only summer blended gasoline. Using gasoline left over from
winter may cause the unit to vapor lock.
STOPPING AND STORING
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 engines 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 carburetor. It is best
extended storage practice to treat the fuel before draining.
D. While the engine is warm, drain the oil and rell 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 cylinder, cylinder head ns, blower
housing, screen, and mufer areas.
F. Store in a clean and dry area.

CONNECTING THE LOADS
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 at, dry location for use.
WARNING: PERSONAL DANGER:
Operating any engine driven generator without proper air ow 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.
APPLYING THE LOADS
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 efciently 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 rst.
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.
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.
GROUNDING
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.
STANDARD PORTABLE GENERATOR
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.
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
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 specically
designed for GFCI and bonded neutral generators is required.
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 qualied electrician and conform to the
National Electric Code and comply with all state and 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.
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 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.

10 REV A
OPM-110
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 xed delay.
If you want to see any specic 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.
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:

Full 3510 58.5 120V 240V
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.

11REV A OPM-110
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 signicantly
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.

run on a CR2032, 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).
= 1-25% = 25-50% = 50-75% = 75-100%
It is good practice to monitor the YourGen Meter when applying load.
This will ensure the generator is balanced.
Balanced Unbalanced
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 9,500 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 insure
compatibility. Remember that power taken from C reduces the power
available equally at both A and B and vice versa.
Change Oil Warning -
After the rst 50 hours, the engine oil should be changed. The YourGen
meter will light up the oil icon ( ) and the word ‘change’ will ash.
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.
Alarms -
The display will start blinking and toggle to the rst parameter that
is out of specication. The panel will remain ashing until the fault
condition returns to within the acceptable range, see following table.

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 sufcient 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.
GENERATOR MAINTENANCE
Any major generator service, including the installation or replacement
of parts, should be performed only by a qualied 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 ns and y wheel. Clean more often if necessary.
Failure to keep these areas clean may cause overheating and
permanent damage to the unit.
2. Periodically clean mufer area to remove all grass, dirt, and
combustible debris to prevent a re.
3. On engine mufers equipped with spark arresters, the spark arrester
must be removed every 50 hours for cleaning and inspection. Replace
if damaged.
