OPM-151/A
INITIAL START UP
WARNING: PERSONAL INJURY
Improper maintenance, or failure to fix any problems
during operation, could cause equipment damage and
possible serious injury. Always inspect unit prior to
operation.
DANGER: DEADLY EXHAUST GAS
Exhaust fumes from any gasoline engine contain
carbon monoxide, an invisible, odorless and deadly gas
that must be mixed with fresh air. Never run an engine
in an enclosed space or near windows or vents.
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
The throttle is electronically controlled on this generator set.
During most operating conditions, it will run at a fixed 3600
RPM.
Always keep the battery charged, especially during cold
weather operation.
1. Check oil level, refill as needed.
2. Turn on the fuel supply. Ref “A”. Lever pointing up or
down is on, lever sideways is off.
3. Turn the engine switch to the “on” position.
4. Operate the starter. Rotate the key switch briefly
to the START position. Do not operate the starter
more than 5 seconds and wait at least 10 seconds
before operating the starter again. Repeat cycle if
necessary.

For your safety always connect the positive battery
cable to the “bat+” terminal
fi
rst. Then connect the
negative battery cable to the “bat-” terminal. Make
sure all connections are clean and tight. Reverse
the sequence when disconnecting, disconnect the
negative cable
fi
rst. These engines produce enough
direct current to keep a battery charged under nor-
mal 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,
fl
ames, and
burning cigarettes away from the battery. Ventilate
the area when charging or using the battery in an
enclosed space. Lead acid batteries contain sulfuric
acid, which causes severe burns. If acid contacts
eyes, skin or clothing,
fl
ush well with water. For con-
tact with eyes, get immediate medical attention.
BATTERY CHARGING
Units equipped with electric start have a small
fl
y-
wheel charger built into the engine
fl
ywheel assem-
bly for recharging the starting battery. This
fl
ywheel
charger generates a small AC current that passes
through a diode assembly to produce a DC charg-
ing current of about 1 to 3 AMPS. This circuit is not
designed to be used as a battery charging circuit to
recharge dead batteries.
OPTIONAL DOLLY KIT
An optional dolly kit is available for this generator.
The dolly kit comes with instructions and parts list.
After installing the dolly kit,
fi
le the instructions and
parts list in the back of this manual for future refer-
ence.
OIL ALERT SYSTEM
This WINCO Industrial generator is equipped with a
low oil shutdown system. This Honda engine uses
an
fl
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 a 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.
INITIAL START UP
The throttle control on these generators is preset
and locked to operate at 3600 RPM (nominal) with
no load speed set at 3690 RPM. Only a trained
service technician should be allowed to adjust this
speed setting.
NOTICE: ENGINE START LOCKOUT
This unit
will not start
if it is low on oil. The lu-
bricating oil level must be at the
full
mark before the
engine will start and run.
BASIC OPERATION
ELECTRIC STARTING
If the engine is cold and stiff or if the battery is not
fully charged, starting can be made easier by slowly
hand cranking the engine through the compres-
sion 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, re
fi
ll as needed
2. Turn on the fuel supply. Ref “A” Lever pointing
up is on, lever pointing down is off.

Some engine applications use a remote-mounted throttle control
rather than the engine-mounted throttle lever shown here. Refer to
the instructions provided by the equipment manufacturer.
Turn the engine switch to
the ON position.
Operate the starter.
Turn the engine switch to the START
position, and hold it there until the
engine starts.
If the engine fails to start within 5
seconds, release the engine switch,
and wait at least 10 seconds before
operating the starter again.
Using the electric starter for more than
5 seconds at a time will overheat the
starter motor and can damage it.
When the engine starts, release the
engine switch, allowing it to return
to the ON position.
Move the throttle lever away from the MIN. position, about 1/3
of the way toward the MAX. position.
Warm up the engine for 2 or 3 minutes.
If the choke knob was pulled to the CLOSED position to start the
engine, gradually push it to the OPEN position as the engine
warms up.
To stop the engine in an emergency, simply turn the engine switch
to the OFF position. Under normal conditions, use the following
procedure. Refer to the instructions provided by the equipment
manufacturer.
Move the throttle lever to the MIN. position.
Some engine applications use a remote-mounted throttle
control rather than the engine-mounted throttle lever shown
here.
Turn the engine switch to the OFF position.
If the fuel tank is equipped with a valve, turn the fuel valve to the
CLOSED or OFF position.

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.
C. This is an electronically controlled engine and will
automatically choke the engine in cold weather.
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.
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,
under varying loads:
