TESTING POLICY
properly engineered. The use of these 3rd party
enclosures is acceptable as long as they have been
certifi 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.
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 specifi ed by the manufacturer of the applicable
engines.
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 fl ow.
UNIT CAPABILITIES
GENERATOR CONNECTIONS
WL12000HE: 120 volt and 240 volt receptacles
are provided for connection to various loads. The
diagram below represents a 12,000 watt (maximum
output) generator. Receptacles A and B are the two
120 volt duplex receptacles. Up to 6,000 watts at
120 volts (50 Amps) can be taken from the generator
at each of the receptacles. This generator produces
120 and 240 volt, 60 Hz (Hertz), AC (Alternating
Current).
Check the appliance or tool nameplates for the current and voltage to insure compatibility. Remember
that power taken from receptacle C reduces the
power available at both A and B and vice versa.
RESTRICTED USES
DO NOT remove from the cradle assembly. Re-
moval of the generator from the cradle assembly
my 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 fl 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 fl ow
and may cause a fi re.

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 current
to start them as to run them. Capacitor motors are
easier to start and usually require 2 to 4 times as
much current to start them as to run them. Repulsion Induction motors are the easiest to start and
require 1 1/2 to 2 1/2 times as much to start them as
to run them.
Most fractional horsepower motors take about the
same amount of current to run them whether they
are Repulsion Induction (RI), Capacitor (Cap), or
4
60706-224
Split-Phase (SP) type. The chart below shows the
approximate current required to start and run various
types and sizes of 120 volt 60 cycle electric motors
under average load conditions.

The fi gures given above are an average load such
as a blower or fan. 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-exiting 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 DAMAGING
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 diffi culty is
experienced in starting motors, turn all other electrical loads off and if possible reduce the load on the
electric motor.

CAUTION: EQUIPMENT DAMAGE
THIS UNIT HAS BEEN SHIPPED WITHOUT OIL.
Failure to maintain the engine oil at the proper level
will result in serious engine damage.
When you unpack your new engine-generator set be
sure to remove all the information sheets and manuals from the carton.
1. This generator-set was in good order when
shipped. Inspect the generator-set promptly after
receiving it. If any damage is noted, notify the transportation company immediately; request proper procedures for fi ling a “concealed damage” claim. Title
to the equipment and responsibility for fi ling a claim
rests with you when a generator-set is sent F.O.B.
shipping point. Only you can legally fi le a claim.
2. Before proceeding with the preparations of your
new generator-set for operation, take a couple of
minutes to insure the unit you have received is the
correct model and review the specifi cation pages in
this manual to insure that this unit meets your job
requirements.
LUBRICATION
Before starting the engine, fi ll the crankcase to the
proper level with a good quality oil. The recommended grade of oil and quantity of oil required is
listed in the engine operator’s manual. 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 the generator or engine manufacturer’s warranty.
GASOLINE
When using gasoline always use a good grade of
unleaded fuel. This engine is certifi ed to operate on
unleaded gasoline with a pump octane rating of 86
or higher. Gasoline containing no more than 10%
ethanol (E10) or 5% methanol by volume may be
used. In addition methanol must contain co-solvents
and corrosion inhibitors. Use of fuels with content
of ethanol or methanol greater than shown above
may cause starting and/or performance problems.
Always insure that the fuel is clean and free of all
impurities.
12020-00 60706-224

WARNING: FIRE DANGER
WARNING: PERSONAL INJURY
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 it’s volatile
properties and you will be left with only the 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 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.
BATTERY INSTALLATION
You will need to purchase and install a battery to
operate it. All electric start engine generator sets are
shipped with a battery kit for customer installation.
This kit consists of a battery tie down, hardware, and
instruction sheet for installation. After installing the
battery and battery hold down kit, fi le the instruction
sheet in the back of this manual for future reference.
A twelve volt battery, BCI group U1 rated at 300
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 fi rst. 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 fi rst. These engines produce enough
direct current to keep a 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, fl 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, fl ush well with water. For con-
tact with eyes, get immediate medical attention.
BATTERY CHARGING
Units equipped with electric start have a small fl y-
wheel charger built into the engine fl ywheel assem-
bly for recharging the starting battery. This fl ywheel
charger generates a small AC current that passes
through a diode assembly to produce a 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 dolly kit is available for this generator.
The dolly kit comes with instructions and parts list.
After installing the dolly kit, fi le the instructions and
parts list in the back of this manual for future reference.
OIL ALERT SYSTEM
All WINCO Industrial generators are equipped standard with low oil shutdown systems. These engine
generator sets come equipped standard with the
Honda Oil Alert System. The Oil Alert system is designed to prevent damage caused by an insuffi cient
amount of oil in the crankcase. Before the oil level in
the crankcase can fall below a safe limit, the Oil Alert
system will automatically shut down the engine (the
engine switch will remain in the ON position).
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 lu-
bricating oil level must be at the full mark before the
engine will start and run.

BASIC OPERATION
ELECTRIC STARTING
If the engine is cold and stiff or if the battery is not
fully charged, starting can be made easier by slowly
hand cranking the engine through the compression stroke before pushing the starter switch. This
permits the starter to gain momentum before the
heavy load of the compression stroke occurs. This
minimizes the drain on the battery and improves the
possibility of starting under such adverse conditions.
Always keep the battery charged, especially during
cold weather operation.
1. Turn on the fuel supply.
2. Move the choke to the full “on” position. A warm
engine will require less choking than a cold engine.
3. Engage the engine start switch briefl y to the
START position. The starter life is improved by
using shorter starting cycles with time to cool off
between cranking cycles. Do not operate the starter
more than 15 seconds during each minute. Repeat
if necessary.
4. When the engine starts, open the choke gradually.
5. 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 overchoking.
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 gasoline.
c. A slightly richer fuel mixture will usually improve
cold starting.
2. Hot weather
a. Use the proper oil for the temperature expected.
b. Use only summer blended gasoline. Using gaso line left over from winter may cause the unit to
vapor lock.
STOPPING AND STORAGE
equivalent will minimize the formation of gum deposits during storage. Such an additive may be added
to gasoline in the engines fuel tank or to gasoline in
a storage container.
a. Remove the remaining fuel from the fuel tank.
b. 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.
c. While the engine is warm, drain the oil and refi ll
with fresh oil.
d. Remove the spark plug, pour approximately 1/2
ounce (15 cc) 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
fi ns, blower housing, screen and muffl er areas.
f. Store in a clean and dry area.
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
The output voltage should be checked to insure
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.
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:
1. Move the on/off switch to the “OFF” position.
2. Before extended storage (over 30 days) certain
precautions must be taken care of to ensure the fuel
doesn’t deteriorate and clog the fuel system. Note:
The use of a fuel additive, such as STA-BIL or an

Generator
Load
None 3690 61.5 125V
Half 3600 60.0 120V
Full 3510 58.5 115V
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.
Whenever making any speed adjustments check the
unit with a voltmeter or tachometer and be sure the
speed is correct.
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 signifi cantly shorten the life of appliances being
used.
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. Frequency can be checked by using
an electric clock with a sweep second hand. Timed
against a wrist watch or a stop watch, the clock
should be correct within +/- 2 seconds per minute.

age 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 Unit Capabilities (page
4).
These engine-generator sets are inherently self reg-
ulating 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 amperage rating is not exceeded.
GROUNDING
All units must be grounded. Drive a 3/4 or 1” copper
pipe or rod into the ground close to the engine-generator set. The pipe must penetrate moist earth.
Connect an approved ground clamp, to the pipe.
Run a no. 10 Awg wire from clamp to the generator
ground lug on the receptacle panel. Do not connect
to a water pipe or to a ground used by a radio system. The engine-generator covered in this manual
is designed for portable use. DO NOT OPERATE
THIS GENERATOR INDOORS. The unit should
be stored in a warm dry location. During a power
outage, move the unit outdoors to a fl at dry location
such as a driveway or sidewalk.
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 effi 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 fi rst.
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within 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 volt-
12020-00
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 qualifi 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 240 volt receptacle. A 4-wire receptacle (two
hot, one ground, and one neutral) has been provided
on the control panel for use in temporay 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 (L14-30P). The use of
locking receptacles and locking plugs provides the
convenience of quick disconnect, for moving, while
allowing workers to safely reconnect the power. In
addition they prevent the plug from being accidentally removed by bumping or vibration.
2. If the generator set is be connected to existing
distribution system a fully isolated manual transfer switch must be installed. The transfer switch
prevents damage to the generator and 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 these portable generators. When installing the generator at these sites, a
secondary emergency distribution panel may have
to be installed, such as the Emergency Transfer/Service (ET/S) system available through your WINCO
dealer. 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.
ENGINE CARE
If major engine service or repair is required contact
an authorized engine service center. The manufacturer of these engines has established an excellent
world-wide engine service organization. Engine service is very likely available from a nearby authorized
dealer or distributor. Check the yellow pages of your
local telephone directory under “Engines-Gasoline”
for the closest engine repair center or ask the dealer
from whom you purchased the power plant.
1. Change the oil after the fi rst month or 20 hours
of operation and every 6 months or 100 hours thereafter under normal operating conditions. Change
engine oil every 25 hours of operation if the engine
is operated under heavy load, or in high ambient
temperatures.
a. Remove oil drain plug at base of the engine and
drain the oil with the engine warm.
b. Replace oil drain plug.
c. Remove oil fi ller plug and refi ll with new oil.
Refer to the table in the engine manual for the
proper grade of oil based on your operating tem perature.
d. Replace fi ller plug.
2. Checking the Oil Level: The oil level must always be checked before the engine is started. Take
care to remove any dirt or debris from around the
oil fi ll plug before removing. Be sure the oil level is
maintained. Fill to the “FULL” mark on the dipstick.
3. Dual Element Air Filter: Clean and or replace
foam pre-cleaner and air fi lter every 6 months or 100
hours. Service more often under dusty conditions.
a. Loosen screws and remove cover and air cleaner
assembly from base.
b. Remove foam pre-cleaner by sliding it off the
paper cartridge.
c. Wash foam pre-cleaner in liquid detergent and
water
d. Wrap foam pre-cleaner in cloth and squeeze dry.
e. Saturate foam pre-cleaner in engine oil. Squeeze
to remove excess oil.
f. Clean Air fi lter using compressed air.
g. Install foam pre-cleaner over air fi lter.
h. Re-install the Air Filter assembly. Reassemble
cover and screw down tight.
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.

GENERATOR CARE
Proper care and maintenance of the generator is necessary to ensure a long trouble free life.
1. Exercising The Generator - The generator
should be operated every three to four weeks. It
should be operated for a period of time suffi 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 insure that the
set is operating properly should it be needed in an
emergency.
2. Generator Maintenance - Any major generator
service including the installation or replacement of
parts should be performed only by a qualifi ed electri-
cal service technician. USE ONLY FACTORY AP-
PROVED 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 dam-
aged or cracked receptacles can be both dan gerous 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. This high pressure spray
could contaminate the fuel system and the generator
components.
3. On engine muffl ers equipped with spark arrest-
ers, the spark arrester must be removed every 50
hours for cleaning and inspection. Replace if damaged.
