BASIC INFORMATION
INTENDED USES
These engine generator sets have been designed primarily
for portable use. Both 120 and 240 volt AC 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. See unit capabilities for further
explanation.
These portable units require large quantities of fresh air for
cooling of both the engine and the generator. Fresh air is
drawn from both the engine end and the generator end and
is exhausted at the center of the unit. For safety, long life
and adequate performance, these units should never be run
in small compartments without positive fresh air flow.
RESTRICTED USES
DO NOT remove from the cradle assembly. Removal of the
generator from the cradle assembly may cause excessive
vibration and damage to the engine generator set.
DO NOT install and operate these portable generators in a
small compartment., i.e. generator compartment of vehicles,
motor homes or travel trailers. These compartments will not
allow enough free flow fresh air to reach the engine
generator set for cooling and will cause the unit to overheat
damaging both the engine and the generator. Small
compartments will also develop hot spots where there is
very little air flow and may cause a fire.
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 a
typical 4000 watt generator. Receptacles A and B are the
two 120 Volt duplex receptacles. Up to 2000 watts at 120
volts (16.6 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).
CAUTION: EQUIPMENT DAMAGE
CAUTION MUST BE EXERCISED TO PREVENT
OVERLOADING EITHER OF THE GENERATORS
120 VOLT OUTPUT CIRCUITS (A OR B).
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. Any remaining 120 volt loads should be equally divided
between A and B. Failure to split the load will cause
permanent damage to the stator. Although circuit breakers are
provided, damage due to overloading constitutes abuse and
will not be warranted. Refer to the generator nameplate for
your unit's capabilities.
Starting Electric Motors - Electric motors require much more
current (amps) to start them than to run them. Some motors,
particularly low cost
and require 5 to 7 times as much current to start them as to
run them.
require 2 to 4 times as much current to start them as to run
them.
usually 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 of RepulsionInduction (RI), Capacitor (Cap), or 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.
HP AMPS SP CAP RI
The figures given above 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-excited generators respond to severe overloading
differently than the power line. 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.
Capacitor motors are easier to start and usually
Repulsion Induction motors are the easiest to start and

CAUTION: EQUIPMENT DAMAGE
RUNNING THE GENERATOR SET UNDER THESE
CONDITIONS MAY RESULT IN DAMAGING THE
GENERATOR STATOR AS WELL AS THE MOTOR
WINDING.
Because 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.

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 new ENGINE GENERATOR be sure to
remove all the information sheets and manuals from the
carton.
1. This power plant was in good order when shipped.
Inspect the power plant promptly after receiving it. If
damage is noted, notify the transportation company
immediately; request proper procedures for filing a
“concealed damage” claim. Title to the equipment and
responsibility for filing a claim rests with you when a
generator is sent F.O.B. shipping point. Only you can
legally file a claim.
2. Before proceeding with the preparation of your new
engine generator set for operation, take a couple of
minutes to insure that the unit you have received is the
correct model and review the specification pages in this
manual to insure that this unit fits your job
requirements.
UNIT PREPARATION
Before your engine generator was shipped from our factory it
was fully checked for performance. The generator was load
tested to its full capacity, and the voltage and frequency were
carefully checked and adjusted.
Lubrication
The use of a 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.
LOW OIL LEVEL WARNING SYSTEM
Briggs & Stratton powered generators - This engine
generator sets come equipped standard with the Briggs &
Stratton OIL GARD warning system.
This low oil warning system will automatically stop the
engine when the oil level is low. This feature is designed to
reduce costly repairs and downtime.
The OILGARD system uses a float in the engine crankcase
to sense the oil level. If a low oil level condition should occur
during operation, the float will ground out the magneto
impulse, “killing” the engine. To get the engine restarted,
you must add the required amount of oil to the engine
crankcase.
Use of the OILGARD system on applications that are subject
to shock, bumping or severe angles of operation (in excess
of 15 degrees) should be avoided. This is especially true if
an unexpected shutdown would cause a safety hazard or
serious inconvenience for the operator.
Optional Dolly Kit
An optional dolly kit is available for this engine generator
set. The dolly kit comes with instructions and parts list. After
installing the dolly kit, file the instructions and parts list in the
back of this manual for future reference.
Before starting the engine, fill 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 are not covered by the generator or the engine
manufacturer's warranty.
Gasoline Fuel
When using gasoline always use a good grade of unleaded
fuel. Leaded gasoline may be used if unleaded is not
available. Gasoline containing alcohol, such as gasohol is not
recommended. However, if gasoline with alcohol is used, it
must not contain more than 10 percent Ethanol and must be
removed from the engine during storage. DO NOT use
gasoline containing methanol. Always insure 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 it's volatile properties and
you will be left with only the varnish residue. This varnish like
substance will clog the carburetor and will not burn properly.
INITIAL START UP
Use the following checklist to verify the correct preparation
of the engine generator before starting.
Before Starting always Check:
1. Engine oil, fill as required with correct grade and
quantity.
2. Fuel level, fill as required with clean fresh fuel.
3. Visually for loose parts. .
STARTING
The throttle control on these generators is preset and locked
to operate at 3600 RPM (nominal) with no load speed set at
3720 RPM. Only a trained service technician should be
allowed to adjust this speed setting. See “Operating Speed”
section for additional information.
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
MANUAL STARTING - Refer to the engine manual for
additional starting, operating, and stopping instructions.
1. Move the choke control to the choke position.
2. Turn the fuel shut-off valve to the on position.
3. Move the stop switch to the run position.
4. Grasp the starter rope and pull slowly untill resistance
is felt. Then pull the cord rapidly to overcome
compression, prevent kickback and start the engine.
Repeat if necessary with the choke in the run postion.
5. When the engine starts move the choke to the run
position.
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 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
gasoline left over from winter may cause the unit
to vapor lock.
c. DO NOT over-choke the unit.
STOPPING AND STORAGE
1. Depress the stop switch mounted on the front of the
engine housing to stop the engine.
2. Turn off the fuel shut-off 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 an equivalent, will
minimize the formation of gum deposits during
storage. Such an additive may be added to gasoline
in the engine’s 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
refill 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 oil. Replace spark
plug.
e. Clean dirt and chaff from cylinder, cylinder
head fins, blower housing, rotating screen and
muffler areas.
f. Store in a clean and dry area.
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 may vary slightly, the
normal voltage and frequency of the engine-generators
described in this book are approximately as follows, under
varying loads:
__________________________________________________________________________________________________________________
LOAD vs. OUTPUT
Generator Frequency Voltage
Load Speed 120V
Applied* (RPM) (Hz) Recpt.
__________________________________________________________________________________________________________________
None 3750 62.5 116V
Half 3600 60.0 120V
Full 3540 59.0 125V
__________________________________________________________________________________________________________________
*Portion of plant’s rated output current.
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 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.

BASIC OPERATION
CONNECTING THE LOADS
Applying The Load
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 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 Unit Capabilities
(page 2).
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
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 “end cover”. Do not
connect to a water pipe or to a ground used by a radio system.
The engine-generators covered in this manual were designed
for portable use. DO NOT INSTALL OR OPERATE THIS
GENERATOR INDOORS. The unit should be stored in a
warm dry location. During a power outage, move the unit
outdoors to a flat dry location such as a driveway or sidewalk.
Many homes today are wired for at least 60 to 100 Amp
entrance service, much greater than the capacity of these
portable generators. Do not attempt to power a home with this
portable generator. This generator set is suitable for powering
individual appliances or emergency lighting.
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 first five hours of operation
and every 50 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 filler plug and refill with new oil.
Refer to the table in the engine manual for the
proper grade of oil based on your operating
temperature.
d. Replace filler 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 fill plug before
removing. Be sure the oil level is maintained. Fill to the
“FULL” mark on the dipstick.
3. Cartridge Air Cleaner - Remove and clean cartridge
yearly or after every 25 hours, whichever occurs first.
Service more often if necessary. Clean by tapping gently on
flat surface. If very dirty, replace the cartridge using only
original equipment parts available at any engine service
center.
Do not use petroleum solvents, such as kerosene, to
attempt to clean the cartridge. They may cause
deterioration of the cartridge. DO NOT OIL CARTRIDGE,
DO NOT USE PRESSURIZED AIR TO CLEAN OR DRY
CARTRIDGE.
4. Dual Element Air Cleaner - Clean and re-oil foam
pre-cleaner at three month intervals or every 25 hours,
whichever occurs first. 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. Install foam pre-cleaner over paper cartridge.

OPERATOR CARE AND MAINTENANCE
5. Spark Plug - Clean and reset gap at .030" every 100
hours of operation. Do not blast clean spark plug. Clean by
scraping or wire brushing and washing with a commercial
solvent. Poor spark will occur if terminal does not fit firmly on
spark plug. If this happens reform the terminal to fit firmly on
spark plug tip.
GENERATOR CARE
Proper care and maintenance of the generator is
necessary to insure 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 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 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 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. This 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 insure 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
flywheel. 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.

Limited Warranty
WINCO warrants to the original purchaser that the alternator is free from defects in workmanship and material for a period of
two years*, provided it is installed, operated and maintained in accordance with WINCO written instructions.
*NOTE: Units used for rental, demonstrations, commercial or prime power applications such as construction or
utility, are warranted for 90 days. Units that are resold are not covered under this warranty. Any further warranty,
whether expressed or implied, rests solely with the reseller.
WINCO’s sole liability, and Purchaser’s sole remedy for a failure under this warranty, shall be limited to the repair of the
product. At WINCO’s option, material found to be defective in material or workmanship under normal use and service will be
repaired or replaced. This warranty does not include circuit breakers, receptacles or ENGINES. Engines are covered
exclusively by the warranties of their respective manufacturers.
THERE IS NO OTHER EXPRESS WARRANTY.
To the extent permitted by law, any and all warranties are limited to 24 months from date of purchase. The user shall
determine the suitability of the product for its intended use prior to placing the unit in service. The user shall assume all risks
and liability in connection with determining the suitability of the unit for its particular use. Neither the manufacturer nor the
seller shall be liable for any injury, loss or damage arising out of improper use or operation of this unit. In no event is WINCO
liable for incidental or consequential damages.
Some states do not allow limitation on the duration of implied warranty and some states do not allow the exclusion or limitation
of incidental or consequential damages, so the above limitations may not apply in every instance. This warranty gives you
specific legal rights which may vary state to state.
WINCO reserves the right to change or improve its products without incurring any obligations to make such changes or
improvements on products previously purchased.
WINCO does not warrant products which have been subjected to misuse, negligence, modified or altered in any way or have
been involved in an accident.
For warranty service, return the product, transportation charges prepaid, to your nearest WINCO Authorized Service Center or
to WINCO at Le Center Minnesota. When requesting warranty service, evidence of original purchase date must be presented.
