OPM-152/A
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
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. Turn on the fuel supply. Ref “A”. Lever pointing up or
down is on, lever sideways is off.
3. Engage the choke by pulling it out. A warm engine
will require less choking than a cold engine.
4. Turn the engine switch to the “on” position.
5. Operating the starter. Rotate the key
switch briefly to the START position. The
starter life is improved by using shorter
starting cycles with time to cool off
between cranking cycles. 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

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,

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.

6. When the engine starts, release the key switch,
allowing it to return to the “on” position.
7. Gradually push the choke as the engine warms up.
8. 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
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. 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 refill with
fresh
oil.
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.
