INTRODUCTION
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.
INTENDED USES
The EC18000VE engine generator set has been designed
primarily for heavy duty commercial use. A 240 volt
receptacle is provided in the control panel to plug in your
loads. The EC22000VE is hard-wire connectible only. 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.
These units require 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 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.
UNIT CAPABILITIES
GENERATOR CONNECTIONS
The diagram below represents this 15,000 watt (rated
output) generator. A & B represent the 120 volt output legs
of this generator. Up to 7500 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
62.5 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.
Check the appliance or tool nameplates for the current
and voltage to ensure compatibility. Remember the power
utilized from C reduces the power available from both A
and B and vice versa. The EC22000 utilizes the same format
with A and B being 9500 Watts and C being 19,000 Watts.
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 difficulty is experienced in starting
motors, turn all other electrical loads off and if possible
reduce the load on the electric motor.

6
60706-231/H
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.
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.
FUEL SUPPLY
The EC units provide flexibility in where they get gasoline
from. Whether you are using our optional fuel tank, or
supplying your own, there are some important factors to
consider. The fuel pump on the unit is only capable of about
30” of lift in ideal circumstances. Tank size, tank location,
hose size, hose routing, and hot spots all play a role in a
successful fuel tank installation. Preferred fuel installations
use 1/4” hose that run straight to the engine with no drops
or twists from an adequately (15 gallons) sized fuel tank.
1. The fuel lift from the bottom of the tank to the fuel
outlet on the generator must not exceed 30”. If a
greater lift is required, it may be necessary to provide
an additional electric fuel pump to ensure the engine
get a sufficient flow of fuel.
2. EPA regulations require the installation of a carbon
canister on the tank vent line. This is to prevent the
escape of fuel vapors in to the atmosphere.
3. You need to have a primer bulb in the fuel line to prime
the fuel from the tank to the fuel pump. The vacuum
fuel pump on the engine will not draw the fuel up from
the tank until the line has been properly primed.
4. In all cases the minimum fuel line size must be 1/4” or
larger line. And the fuel line must be certified for use
with unleaded gasoline.
LUBRICATION
Before starting the engine, fill the crankcase to the proper
level with a good quality 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 78 - 80 oz (2.4 - 2.5 qts) 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 over
PREPARING THE UNIT
UNPACKING
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 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.
VENTILATION
These engine generator sets use large amounts of fresh
air for cooling. When designing plans for your installation,
special attention must be paid to the flow of hot air from
both the engine and the generator. Both the engine and
the generator must be supplied with a constant flow of
fresh air from the outside to ensure they don’t overheat.
Some provision must be made to remove the hot air out the
enclosure. Ambient temperature around the unit should
not exceed 104°F. Engine or generator failures resulting
from inadequate ventilation are considered abuse and
not covered by the generator or engine manufacturer’s
warranty.
The engine exhaust from this engine must be vented to the
outside. When venting hot exhaust through any type of
flammable wall be sure to use exhaust thimbles to prevent
fires.
WARNING:
Failure to properly vent out the exhaust out of an
enclosure can and will kill you. Carbon monoxide is both
invisible and orderless, it can build up very rapidly in any
enclosure not properly vented.
GASOLINE
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.
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.

760706-231/H
fill 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 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.
OIL RECOMMENDATIONS
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.
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 insufficient 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.
BATTERY INSTALLATION
You will need to connect this unit to a battery to operate
it. Cables have not been provided as length are going to
vary depending on your installation. These engines are
all negative ground. The positive battery cable must be
connected to the open large terminal on the start solenoid
(This terminal may have a small 16 GA. wire on it for the
charging circuit). The negative cable should be attached
to a good ground on the engine. This is usually one of the
starter mounting studs.
A twelve volt battery, rated at 300 CCA or larger is
recommended for this electric start generator set. Follow
the battery manufacturer’s recommendations for servicing
and charging prior to use.
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 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.
WARNING: PERSONAL INJURY
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.
BATTERY CHARGING
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.

8
60706-231/H
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 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 cylinder, cylinder head fins,
blower housing, screen, and muffler 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 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.
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,
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. Turn on the fuel supply
2. Using the primer bulb, make sure the fuel is pumped
up the the fuel pump on the engine.
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 postion. Thart 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.

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.
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.
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.
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.

10
60706-231/H
CONNECTING THE LOADS
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 the time. Improper loading of the generator
set constitutes abuse and will not be covered by warranty.
A 60 Amp receptacle (NEMA 14-60) has been provided
to allow the connection of loads to the generator on the
EC18000VE. This receptacle is a 4-wire, full load receptacle
protected by a 60 Amp breaker mounted in the control box
on top of the generator.
With the EC22000VE, the load wiring must be wired
directly in the 80 Amp breaker mounted in the control box
on top of the generator. When wiring directly to the circuit
breaker in the box, be sure to connect a neutral wire and
ground wire to the appropriate locations in the control box.
Your individual loads must be protected by individual circuit
breakers mounted in some type of distribution panel. This
location will also be where you will install your neutral
to ground bond. You must wire four separate wires from
the generator (2-hot, 1- neutral, and 1-ground) to the
distribution panel.
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 shot 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.
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. The generator is a limited source of electrical
power, therefore, pay special attention to the receptacle
and generator ratings.
GROUNDING
All units must be grounded. Different installations will
require different grounding requirements. Depending
on your installation, ensure that the ground meets your
governing codes.
WIRING
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.
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.

properly.
d. Before you install the new oil filter, lightly lubri-
cate the oil filter gasket with fresh clean oil.
e. Install the oil filter by hand until the gasket
contacts the oil filter adapter, then tighten the oil
filter 1/2 to 3/4 turns.
f. Replace oil drain plug.
g. Remove oil filler plug and refill with new oil.
Refer to the table on page 5 for the proper
grade of oil based on your operating
temperature.
NOTE: This engine requires 78 to 80 ounces of oil
if it is completely drained. Use caution when refilling
the engine as some residual oil may have remained
in the engine. Always use the dipstick when filling
the engine with oil to prevent overfilling.
h. Replace filler plug.
I. Start the engine and warm it up.
J. After warming up the engine, recheck the oil
level and refill as necessary to bring it to the
proper level. See page 5 for proper oil level.
2. Checking the Oil Level: The oil level must al-
ways be checked before the engine is started. Take
care to remove any dirt or debris from around the
oil fill 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 filter annually or every 100
hours. Service more often under dusty conditions.

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 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
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.
H. Install the air filter and secure the retainer and nut.
I. Install and secure the cover.
SPARK PLUG
Replace annually or every 300 hours of operation. Always
replace with the same spark plug that came in the engine
and check gap before installing. Spark plug gap is 0.030”.
Poor spark will also occur if spark plug wire does not fit
firmly on spark plug. If this happens, reform the terminal to
fit firmly on spark plug tip.
CARBON CANISTER
Designed to collect, store, and dispose of fuel vapors
created in the fuel tank/fuel system. The canister should last
the life of the unit as long as it stays dry.
