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
This engine generator set has been designed primarily for
portable heavy duty commercial use.
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 operate generator where it could get wet or have
pooling water near it. This generator is NOT weatherproof.
Failing to keep generator in a dry area may cause an
electrical shock, resulting in injury or death.
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 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 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 engineered and meet
applicable 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
CAUTION: EQUIPMENT DAMAGE
Check phase rotation. Improper phase rotation can result
in equipment damage.
W6010KE: All models use wye (star) dedicated generator
ends that cannot be reconnected. All nameplate ratings
for amps and KVA are at a 0.8 PF. Some loads operate at
1.0 PF which will reduce the number of amps available but
not the available KW. See page 4 of this manual for 1.0 PF
amperage capabilities.
Each generator provides loads from three winding groups
of equal capacity. It is essential that care is taken to properly
balance the load between the winding groups.
When the load is connected between any line and
the neutral (example A), the load is concentrated on
one winding group with an amperage rating equal to
specification at 1.0 PF. You can create a balanced load by
dispersing your L-N loads between each leg.
When the load is connected between any Line to Line
(example B), the load is concentrated on two of the three
winding groups with an amperage rating equal to the
specification at 1.0 PF. You can create a balanced load by
offsetting connections.
A three phase load connected to all legs (example C), the
load is evenly split between all three winding groups. the
load can be at 0.8 or 1.0 PF.
You may run multiple connections types at the same time as
long as they do not exceed the machine’s nameplate rating.
Each connection type will reduce the amperage available
on each winding group.
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. The
following chart shows the approximate current required to
start and run various types and sizes of 120 Volt 60 cycle
electric motors under average load conditions.
STARTING AMPS
HP Running
Amps
Split Phase
Motor
Capacitor

1/6 3.2 16 to 22 6 to 13 5 to 8
1/4 4.5 22 to 32 9 to 18 7 to 12
1/3 5.2 26 to 35 10 to 21 8 to 17
1/2 7.2 Not Made 14 to 29 11 to 18
113 Not Made 26 to 52 20 to 33
The figures given in the previous chart are for 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-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 may 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.
Motor starting capacity - 2HP code ‘G’ capacitor start
engine.
Trying to start a larger motor or higher code motor, i.e. ‘J’
or ‘K’, may result in damage to both the generator and the
electric motor, especially 120 Volt motors.
LOAD TYPES
This generator is designed and rated for general
commercial use. The running watts rating assumes a
variable load. If your application has a fixed load that does
not vary, an additional derate of 20% from the running
watts is recommended to ensure the longest useful life of
the engine and generator end.

7OPM-133/F
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.
DIESEL FUEL
Always use a good grade of # 2 diesel fuel. For cold
weather, blended #1 fuel may be used. Fuel cetane number
should be 45 or higher and the fuel MUST be low sulfur
or ultra low sulfur fuel. See engine operators manual for
additional fuel recommendations including Bio-Diesel fuel.
Never use gasoline or gasohol. Always ensure that the fuel
is clean and free of all impurities. Always be sure to keep the
strainer in place when filling the fuel tank.
WARNING: FIRE DANGER
Diesel fuel is flammable and can be ignited, causing or
enlarging fires when proper precautions are not taken.
Never use fuel that has been stored for an extended period
of time. Fuel will lose its volatile properties and you will
be left with a ‘gum’ or varnish residue. This varnish-like
substance will clog the filters, fuel lines, and injectors. Old,
contaminated, stale fuel will not burn properly. The use of
a diesel fuel additive, 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.
PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
Always check oil level prior to use. 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.
LUBRICATION
CAUTION: EQUIPMENT DAMAGE
Failure to maintain the engine oil at the proper level will
result in serious engine damage.
Before starting the engine, verify the crankcase is filled 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 oil in it. The engine normally
holds 1.3 quarts (41.6 oz.) of oil. Use the dipstick to ensure
that you have the proper oil level in 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.

BATTERY INSTALLATION
This engine generator set is shipped with a battery tie down
for customer installation.
A customer supplied 12 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.
Installation and servicing of batteries must be performed or
supervised only by personnel knowledgeable of batteries
and the required precautions. Keep unauthorized personnel
away from batteries.
When installing or replacing batteries, use proper group/
size starting battery. The battery should be a maintenance
free lead acidic design. Deep cycle batteries will NOT work
for this application.
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.
CAUTION
Do NOT open or mutilate the battery. Released electrolyte
is known to be harmful to the skin and eyes and to be very
toxic. A battery presents a risk of electrical shock and high
short circuit current. The following precautions must be
observed when working with batteries:
1. Remove watches, rings and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the battery
posts to be sure they are free of corrosion.
4. Always connect the battery positive first and then
connect the battery negative cable. When removing
the battery cables from the battery reverse the
procedure, disconnect the negative cable first and
then the positive cable.
5. Be sure all connections are tight and coat the
terminals and cable end with dialectic grease.
DANGER: EXPLOSIVE FIRE RISK
Never smoke when near batteries. Do not cause a flame or
spark in the battery area. Always discharge static electricity
from your body before touching batteries by first touching
a ground metal surface.
WARNING
The electrolyte is diluted sulfuric acid that is harmful to the
skin and eyes. It is electrically conductive and corrosive.
The following precautions must be always be taken.
1. Always wear full eye protection and protective
clothing.
2. Where electrolyte contacts skin, wash off immediately
with water.
3. If electrolyte contacts the eyes, flush thoroughly and
immediately with water and seek immediate medical
attention.
4. Spilled electrolyte is to be washed down with an acid
neutralizing agent. A common practice is to use a
solution of one pound of bicarbonate of soda (baking
soda) to one gallon of water. The bicarbonate of soda
solution is to be added until the evidence of reaction,
foaming, has ceased. The resulting liquid is to be
flushed water and the area dried.
SERVICING BATTERIES
Batteries used on these units may over time lose water.
This is especially true if you are using a trickle charger to
maintain your battery. When refilling the battery with water
use only distilled water. Tap water will shorten the service
life of the battery.
Never fill the battery above the fill line. Overfilling above
the upper level line may cause the electrolyte to overflow,
resulting in corrosion to the engine or nearby parts.
Immediately wash off any spilled electrolyte following the
procedure above.
Note: always make sure that a new battery is fully charged
before installing it on a generator set.
All connections must be clean and tight. Check the
electrolyte (fluid) in the battery periodically to be sure it is
above the plates. Never allow the battery to remain in a
discharged condition.
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.

10
OPM-133/F
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. This engine will not start without a battery. The
fuel shut-off solenoid requires 12V DC to operate.
BASIC OPERATION
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. Check oil level, refill as needed.
2. Make sure the fuel solenoid valve lever is in the down
position. This lever should never be put in the up position.
The lever is located under the key switch as pictured.
3. Turn key to 1st position (Ref A).
4. Turn key to the 2nd position - starting (Ref B).
A
B
5. Return key to 1st position when engine is running (Ref A).
NOTE: While the engine is running, all warning lights
should be off except the OK light.
STARTING HINTS
1. COLD WEATHER
Use the proper oil for the temperature expected.
CAUTION: EQUIPMENT DAMAGE
Never use ether or any other starting aides. Serious engine
damage or personal injury may result from ignoring this
simple warning.
2. HOT WEATHER
Use the proper oil for the temperature expected.
STOPPING
1. Move the key to the “OFF” position.
2. Make sure the fuel solenoid valve lever is in the down
position. The lever is located under the key switch as
pictured. The generator will not shutdown if this lever is
in the up position.
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: 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.
A. While the engine is warm, drain the oil and refill with
fresh oil.
B. Clean dirt and chaff from cylinder, cylinder head fins,
blower housing, screen, and muffler areas.
C. 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 flat, dry location for use.
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.
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 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.
CAUTION: EQUIPMENT DAMAGE
Diesel engines should never be run for an extended period
of time with a very light load or no load on them, it may
do permanent damage to the engine if run under these
conditions.
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 specifically 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 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.

12
OPM-133/F
CAUTION: EQUIPMENT DAMAGE
Check phase rotation. Improper phase rotation can result
in equipment damage.
1. These engine-generator sets are designed for portable
heavy duty commercial use. On 208/230V machines,
receptacles are provided on the control panel to permit
both L-N and L-L connections. Each of the three L-N
receptacles is connected to one leg allowing for an
evenly balanced loads. The full power plug is capable of
three phase power.
The 480V machines are not equipped with any L-N plugs
and come with a full power receptacle.
Each generator ships with a compatible full power plug.
Consult a licensed electrician for wiring the TemPower
plug and connecting it as temporary service.
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.

ENGINE CARE
MAINTENANCE SCHEDULE
* If engine use is infrequent; every year
** If engine use is infrequent; every 2 years
If you are using oil of a quality lower than the
recommended one then you will have to replace it every
150 hours
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.
CHANGING THE OIL
Change the oil after the first 50 hours of operation and
yearly or 250 hours thereafter under normal operating
conditions.
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.
A. Change oil while the engine is still warm, the oil will
flow more freely.
B. Remove the oil drain bolt at base of the engine and
drain the oil into an approved container.

C. Replace oil drain plug.
D. Remove oil fill cap.
E. Fill to correct level with oil. Reinstall cap.
F. Remove the oil filter and dispose of it properly.
NOTE: This engine requires 41.6 oz. (1.3 qts) 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 oil filter and filter 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.
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 plug before removing. Be sure the oil level is
maintained. Fill to the “FULL” mark on the dipstick.
AIR FILTER
Clean the filtering element with air blast. Air must be blown
from inside to outside the cartridge at a distance of at least
6 inches from the paper. Lightly and repeatedly tap the
element on a hard surface to eliminate all excess dirt.
WARNING: EQUIPMENT DAMAGE
Never start or run the engine with the air filter removed.
A. Remove the cover.

B. Remove the wing nut.
C. Remove the filter element.
D. Check the rubber seal is undamaged.
E. To loosen debris, gently tap the air filter on a hard
surface. If the air filter is excessively dirty replace with a
new filter. You can use pressurized air (not to exceed
30 psi) to clean the filter. Always blow the compressed
air from inside to the outside.
F. Clean the dirt from the inside of the air cleaner body
and cover. Reinstall the filter in housing. Tighten the
wing nut securely.
G. Install and secure the cover.
H. Remove and clean the pre-filter if clogged.
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.
