OPM-129/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.
BASIC OPERATION
RECOIL 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 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. Depress the toggle switch located on
the receptacle panel, to RUN.
3. To start a cold engine, move
the choke rod to the CLOSED
position.
4. Operate the starter. 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.
5. 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.
6. 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.
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 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.
3. Engage the choke by pulling it out.
A warm engine will require less
choke than a cold engine.
4. Depress the toggle switch located on
the
receptacle panel, to RUN. Press the START button
to turn the engine over. As soon as the engine is
running, the Start button should be released.
5. Gradually push the choke as the engine warms up.
6. 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, simply turn the engine toggle switch to
STOP.
