OPM-140/E
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
CAUTION: EQUIPMENT DAMAGE:
Always start the unit with the circuit breaker open, never
start with the load applied. Always keep the battery
charged, especially during cold weather operation.
1. Check oil level, refill as needed.
2. Turn on the fuel supply.
3. Move the choke to the full “ON” position for starting.
A warm engine will require less choking than a cold
one.
4. Turn the key to the start position. The starter life is
improved by using shorter start cycles. Do not operate
the starter more than 15 seconds during each minute.
Repeat as necessary.
5. When the engine starts, release the key and open the
choke
gradually.
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
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. 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 practice to treat the
fuel before draining.
D. While the engine is warm, drain the oil and refill with
fresh
oil.
E. Remove the spark plug, pour approximately 1/2 oz.
(15cc) of engine oil into the cylinder and crank slowly
to distribute the oil. Replace the spark plug.
E. Clean dirt and chaff from cylinder, cylinder head fins,
blower housing, screen, and muffler areas.
F. Store in a clean and dry area.
