a. Add the fuel stabilizer to the fuel in the tank
and run the unit 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 the carburetor. It is best for extended storage
to treat the fuel before draining.
d. While the engine is warm, drain the oil and
refi ll with fresh oil.
e. Clean dirt and chaff from cylinder, cylinder
head
fi ns, blower housing, screen and
muffl er 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 volt-
age 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 con-
nected 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 equip-
ment 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-gen-
erator described in this manual are approximately as
follows, under varying loads:

The speed of the engine was carefully adjusted at
the factory so that the generator produces the proper
voltage and frequency. For normal usage, the speed
setting should not be changed. If the generator is
being run continuously on a very light load, it is often
advisable to lower the operating speed slightly.
CAUTION: EQUIPMENT DAMAGE
SPEED ADJUSTMENTS SHOULD ONLY BE
MADE BY A QUALIFIED SERVICE TECH. When-
ever making any speed adjustments, check the
unit with a voltmeter and a frequency meter or
tachometer and be sure the voltage and speed
are correct.
Lower voltage may damage both the generator and
any load connected to it. Running the engine at ex-
cessively high speeds results in high voltage, which
may signifi cantly shorten the life of appliances being
used.
Output voltage should be checked periodically to
ensure continued proper operation of the generat-
ing plant and appliances. If the generator is not
equipped with a voltmeter, it can be checked with a
portable meter.
CONNECTING THE LOADS
Allow the engine to warm up for two or three minutes
before applying any load. This will allow the engine
to reach normal operating temperature and oil to cir-
culate throughout the engine. A short warm-up time
will permit the engine to work more effi ciently when
the load is applied and will reduce the wear in the
engine, extending its life.
Receptacles have been provided to allow loads to
be connected to the generator. The loads should
be added one at a time. If a large motor is being
started; or multiple motors are being started, they
should be started individually and the largest should
be started fi rst.
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within the generator and
receptacle nameplate rating. Overloading may cause
damage to the generator and/or the loads .
