INTRODUCTION
INTENDED USES
This engine generator set has been designed primarily for portable
heavy duty commercial use. Both 120 volt, NEMA 5-20R has been
provided in the control panel to plug in your loads (lights, portable tools,
and small appliances).
This portable unit requires large quantities of fresh air for cooling the
engine and generator. For safety, long life and adequate performance,
these units should never be run in small compartments without positive
fresh air ow.
RESTRICTED USES
DO NOT remove from the cradle assembly. Removal of the generator
from the cradle assembly may cause excessive vibration and damage
to the engine-generator set.
DO NOT install and operate this generator in a small compartment.,
i.e. generator compartments of vehicles, motor homes or travel
trailers. These compartments will not allow enough free ow of fresh
air to reach the engine generator set for cooling and will cause the
unit to overheat, damaging both the engine and generator. Small
compartments will also develop hot spots where there is very little air
ow and may cause a re.
PLEASE NOTE There are 3rd party companies making enclosures for
generators that have been properly engineered. The use of these 3rd
party enclosures is acceptable as long as they have been certied and
meet current code.
DO NOT attempt to operate at 50 cycles. These units are designed and
governed to operate at 60 cycles only.
UNIT CAPABILITIES
GENERATOR CONNECTIONS
DP3000/T: Rated at 3,000 starting Watts and 2,500 continuous Watts.
Generator full output can be drawn from the 120 Volt GFCI NEMA 5-20
receptacles, mounted on the end of the generator.
STARTING ELECTRIC MOTORS
Electric motors require much more current (amps) to start than to run.
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.
PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
THIS UNIT HAS BEEN SHIPPED WITH OIL. Failure to maintain the
engine oil at the proper level will result in serious engine damage.
When you unpack your engine-generator set be sure to remove all the
information sheets and manuals from the carton.
1. As you receive your unit, it is critical to check it for any damage. If
any damage is noted, it is always easiest to refuse the shipment and
let WINCO take care of the freight claim. If you sign for the unit, the
transfer of the ownership requires that you le the freight claim
2. Before proceeding with the preparations of your new generator
for operation, take a couple of minutes to ensure the unit you have
received is the correct model and review the specication pages in this
manual to ensure that this unit meets your job requirements.
LUBRICATION
Before starting the engine, check that the crankcase has the proper
level of a good quality oil. The recommended grade oil and quantity
of oil required is listed in the engine operator’s manual and in the Oil
Recommendations section of this manual. The engine normally holds
19.5 ounces (0.61 quarts) of oil. Use the dipstick to ensure that you
Most fractional horsepower motors take about the same amount
of current to run them whether they are Repulsion Induction (RI),
Capacitor (Cap), or Split-Phase (SP) type.
If the electric motor is connected to a hard starting load such as an air
compressor, it will require more starting current. If it is connected to a
light load, or no load such as a power saw, it will require less starting
current. The exact requirement will also vary with the brand or design
of the motor.
Self-exciting generators respond to severe overloading differently than
utility power. When overloaded, the engine is not able to supply enough
power to bring the electric motor up to operating speed. The generator
responds with high initial starting current, but the engine speed drops
sharply. The overload may stall the engine. If allowed to operate at very
low speeds, the electric motor starting winding will burn out in a short
time. The generator winding might also be damaged.
CAUTION: EQUIPMENT DAMAGE
Running the generator set under these conditions may result in
damage to the generator stator as well as the motor winding.
The heavy surge of current required for starting motors is required for
only an instant. The generator will not be damaged if it can bring the
motor up to speed in a few seconds of time. If difculty is experienced
in starting motors, turn all other electrical loads off and if possible
reduce the load on the electric motor.

5REV B OPM-116
have the correct amount of oil. The full oil level mark on the dipstick is
depicted in the following image.
If needed, oil is added to the engine by removing the oil cap and adding
oil at this point. After lling the crankcase to the proper level, be sure
you properly tighten the oil ll cap.
NOTE: This engine generator must be on a level surface before you
check or add oil to the system.
The necessity of using the correct oil and keeping the crankcase full
cannot be overemphasized. Engine failures resulting from inadequate
or improper lubricant are considered abuse and not covered by the
generator or engine manufacturer’s warranty.
OIL RECOMMENDATIONS
Outdoor temperatures determine the proper oil viscosity for the
engines. Use the chart to select the best viscosity for the outdoor
temperature range expected.
OIL ALERT SYSTEM
This generator is equipped with a low oil shutdown system. This
Honda engine uses an oat switch mounted inside the engine. If the
oil level drops below a certain point the low oil module on the engine
will shut it down. This low oil warning system will automatically stop the
engine before the oil level reaches critical danger point. This feature is
designed to prevent costly repairs and downtime.
CAUTION: EQUIPMENT DAMAGE
Allowing the engine to shutdown repeatedly on low oil level may cause
excessive wear which can be cumulative.
GASOLINE
When using gasoline, always use fresh, clean, unleaded fuel. The
engine is certied to operate on unleaded gasoline with a minimum
octane rating of 87 or higher. Gasoline containing no more the 10%
ethanol is acceptable.
CAUTION: EQUIPMENT DAMAGE
Do not use unapproved gasolines, such as E15 or E85. Do not mix
oil in the gasoline. Use of unapproved fuels will damage the engine
components and void the engine warranty.
Use of fuels with content of ethanol greater than shown above may
cause starting and/or performance problems. Always ensure that the
fuel is clean and free of all impurities.
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when proper precautions
are not taken.
Never use gasoline that has been stored for an extended period of
time as the fuel will lose its volatile properties and you will be left with
varnish residue. The varnish like substance will clog the carburetor and
will not burn properly.
The use of fuel additives, such as Sta-Bil, or an equivalent will minimize
the formation of fuel gum deposits. If a unit has been out of operation
for an extended period of time, it is best to drain old fuel from the
engine and replace with fresh fuel before attempting to start.
See the engine manual for special instruction for operating this unit at
over 5000 feet.
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
1. Check oil level, rell as needed.
2. Move the fuel valve and fuel cap vent to the ON position.
3. To Start a cold engine, move the choke rod to the CLOSED
position.
To restart a warm engine, leave the choke lever in the open
position.

6REV B
OPM-116
4. Turn the engine switch to the ON position.
5. Operate the starter. This engine is recoil start only. Pull the
starter grip lightly until you feel resistance, then pull briskly
in the direction of the arrow as shown below. Return the
starter grip gently.
Note: Do not allow the starter grip to snap back against the engine.
Return it gently to prevent damage to the starter.
6. If the choke rod has been moved to the CLOSED position to
start the engine, gradually move it to the OPEN position as the
engine warms up.
7. The engine should promptly come up to operating speed.
CAUTION: EQUIPMENT DAMAGE
Never permit the choke to remain on after the engine has run for a
short time. It is not necessary to choke the engine when it is warm.
Avoid over-choking.
STARTING HINTS
1. COLD WEATHER
A. Use the proper oil for the temperature expected.
B. Use fresh winter grade fuel. Winter grade gasoline is blended to
improve starting. Do not use summer grade gasoline.
2. HOT WEATHER
A. Use the proper oil for the temperature expected.
B. Use only summer blended gasoline. Using gasoline left over from
winter may cause the unit to vapor lock.
STOPPING AND STORING
To stop the engine in an emergency, simply turn the engine switch to
OFF position. Under normal conditions, use the following procedure.
1. Allow the generator to run under no load for at least 2 minute to
cool. Turn the engine switch to the OFF position.
2. Turn the fuel valve lever to the OFF position.
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. If you choose to 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 rell with fresh oil.
E. Clean dirt and chaff from cylinder, cylinder head ns, blower
housing, screen, and mufer areas.
F. Store in a clean and dry area.
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.

7REV B OPM-116
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:
LOAD vs. OUTPUT
Generator
Load
Speed
(RPM)
Frequency
(Hz)
Voltage
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 charged. If the generator is
being run continuously on a very light load, it is often advisable to lower
the operating speed slightly.
Position the throttle lever for the desired engine speed.
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 signi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.
CONNECTING THE LOADS
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 efciently when the load is
applied and will reduce the wear in the engine, extending its life.
Receptacles have been provided to allow loads to be connected to the
generator. The loads should be added one at a time. If a large motor
is being started: or multiple motors are being started, they should be
started individually and the largest should be started rst.
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within in the generator and receptacle
nameplate rating. Overloading may cause damage to the generator
and/or the loads.
Most electric tools and appliances will have the voltage and amperage
requirements on their individual nameplates. When in doubt, consult
the manufacturer or a local electrician. The nameplate amperage rating
for electric motors can be misleading. See “Starting Electric Motors” in
the Unit Capabilities.
These engine-generator sets are inherently self regulating based on
engine speed. The engine governor will automatically adjust itself to
the load. No harm to the generator will result if it is operated with no
load connected. Proper utilization of the receptacles located on the
control panel is necessary to prevent damage to either the receptacles
or the generator. The generator is a limited source of electrical power,
therefore, pay special attention to the receptacle and generator ratings.
The nameplate rating can be obtained through a single receptacle as
long as the receptacles amperage rating is not exceeded.
GROUNDING
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 the 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-generators covered in this manual were
designed primarily for portable use. If you are connecting into a building
wiring system that is already grounded using the 14-30 4 wire plug, you
do not have to ground the unit.
WARNING: PERSONAL DANGER
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 at, dry location such as a driveway or sidewalk.

8REV B
OPM-116
WIRING
Plug your tools such as drills, saws, blowers, sump pump, and
other items to be powered directly into the generator receptacles.
Before plugging in all the tools and cord sets, recheck the rating
of the generator set. Be sure it can handle the intended load and
is compatible with the voltage, phase, and current ratings. ‘Hard
wiring’ this unit directly into a temporary construction site electrical
system is NOT A SIMPLE DO-IT-YOURSELF JOB. For your safety,
all wiring must be done by a qualied electrician and conform to the
National Electric Code and comply with all state and local codes and
regulations. Check with local authorities before proceeding.
WARNING: PERSONAL DANGER
A fully isolated, double pole double throw manual transfer switch must
be installed any time a generator is being connected to an existing
distribution system.
1. These engine-generator sets are designed for portable heavy duty
commercial use. Receptacles are provided on the control panel to
permit 120 Volt portable appliances and tools to be plugged directly
into them. On this size generator, no provisions have been made
for plugging into an existing building wiring. Because of the 120V
receptacle is a GFCI design, connecting to any wiring system with a
neutral to ground jumper in it will cause the GFCI to trip. Consult a
licensed electrician for wiring and connecting it as temporary service.
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 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. See following table.
CHECKING THE OIL LEVEL
The oil level must always be checked before the engine is started.
Refer to page 5 of this manual for instructions on checking the oil level.
Take care to remove any dirt or debris from around the oil plug before
removing. Be sure the oil level is maintained.
CHANGING THE OIL
Refer to the Maintenance Schedule Chart for required oil change
intervals.
1. Start the engine and warm it
up, stop the engine and remove the
spark plug wire to prevent it from
accidentally being started.
2. Allow the used oil to drain
completely, then reinstall the oil drain
plug and a new washer, and
tighten the oil drain plug securely.

9REV B OPM-116
Dispose of used motor oil in a manner that is compatible with the
environment. Do not throw it in the trash, pour it in the ground, or pour
it down a drain.
3. With the engine in a level position, ll with the recommended oil
to the upper limit mark on the dipstick.
The Oil Alert system will automatically stop the engine before the
oil level falls below the safe limit.
CAUTION: EQUIPMENT DAMAGE:
Running the engine with a low oil level can cause engine damage. This
type of damage is not covered under warranty.
4. Install the oil ller cap/dipstick and tighten securely.
NOTE: This engine requires 19.5 ounces (0.61 quarts) of oil if it is
completely drained. Use caution when relling the engine as some
residual oil may have remained in the engine. Always use the dipstick
when lling the engine with oil to prevent overlling.
5 . After warming up the engine, recheck the oil level and rell as
necessary to bring it to the proper level.
AIR FILTER
Check maintenance schedule for recommended service period. Service
more often under dusty conditions.
WARNING: EQUIPMENT DAMAGE
Never start or run the engine with the air lter removed. This will allow
dirt to enter the engine, causing rapid engine wear. This type of
damage is not covered under warranty.
1. Remove the wing nut from the air
cleaner cover and remove the
cover.
2. Remove the wing nut from the air
lter and remove the lter.
3. Remove the foam lter from the
paper lter.
4. Inspect both air lter elements and
replace them if they are damaged.
Always replace the paper air lter
element at scheduled intervals.
5. Clean the air lter elements if they
are to be reused.
Paper air lter element: Tap the lter element several times on a
hard surface to remove dirt, or blow compressed air [not
exceeding 30 psi through the lter element from the inside. Never
try to brush off dirt; brushing will force dirt into the bers.
Foam air lter element: Clean in warm soapy water, rinse, and
allow to dry thoroughly. Or clean in nonammable solvent and
allow to dry. Dip the lter element in clean engine oil, then
squeeze out all excess oil. The engine will smoke when started if
too much oil is left in the foam.
6. Wipe dirt from the inside of the air cleaner case and cover, using
a moist rag. Be careful to prevent dirt from entering the air duct
that leads to the carburetor.
7. Place the foam air lter element over the paper element, and
reinstall the assembled air lter. Be sure the gasket is in place
beneath the air lter. Tighten the air lter wing nut securely.
8. Install the air cleaner cover, and tighten the wing nut securely.
SEDIMENT CUP
DANGER: PERSONAL INJURY
Gasoline is highly ammable and explosive, and you can be burned or
seriously injured when handling fuel.
1. Remove the fuel valve to the OFF position, then remove the fuel
sediment cup and O-Ring.
2. Wash the sediment cup in non-ammable solvent, and dry
thoroughly.
3. Place the O-Ring in the fuel valve and install the sediment cup.
Tighten the sediment cup securely.
4. Move the fuel valve to the ON position, and check for leaks.
Replace the O-Ring if there is any leakage.
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 t rmly on spark plug. If this happens, reform the
terminal to t rmly 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.

10 REV B
OPM-116
GENERATOR CARE
Proper care and maintenance of the generator is necessary to ensure a
long trouble free life.
EXERCISING THE GENERATOR
The generator should be operated every three to four weeks. It should
be operated for a period of time sufcient to warm the unit up and to
dry out any moisture that has accumulated in the windings. If left, this
moisture can cause corrosion in the winding. Frequent operation of the
engine-generator set will also ensure that the set is operating properly
should it be needed in an emergency.
GENERATOR MAINTENANCE
Any major generator service, including the installation or replacement
of parts, should be performed only by a qualied electrical service
technician. USE ONLY FACTORY APPROVED REPAIR PARTS.
A. Bearing - The bearing used in these generators is a heavy duty,
double sealed ball bearing. They require no maintenance or
lubrication.
B. Receptacles - Quality receptacles have been utilized. If a
receptacle should become cracked or otherwise damaged,
replace it. Using damaged or cracked receptacles can be both
dangerous to the operator and destructive to the equipment.
CLEANING
Remove dirt and debris with a cloth or brush. DO NOT use high
pressure spray to clean either the engine or the generator. The high
pressure spray could contaminate the fuel system and the generator
components.
1. Keep the air inlet screen on both the engine and generator free of
any dirt or debris to ensure proper cooling. At least yearly, remove
the blower housing on the engine and clean the chaff and dirt out of
the engine cooling ns and y wheel. Clean more often if necessary.
Failure to keep these areas clean may cause overheating and
permanent damage to the unit.
2. Periodically clean mufer area to remove all grass, dirt, and
combustible debris to prevent a re.
3. On engine mufers equipped with spark arresters, the spark arrester
must be removed every 50 hours for cleaning and inspection. Replace
if damaged.
