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 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.
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:
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. Turn on the fuel supply
2. Using the primer bulb, make sure the fuel is pumped up the the
fuel pump on the engine.
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 postion. Thart 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.
