STARTING HINTS
Cold Weather
1. Use the proper oil for the temperature expected.
2. Use fresh winter grade fuel. Winter grade fuel is
blended to improve starting. Do not use old or straight
summer blend fuel.
CAUTION: EQUIPMENT DAMAGE
Never use ether or any other starting aides. Serious en-
gine damage or personal injury may result from ignoring
this simple warning.
Hot Weather
1 Use the proper oil for the temperature expected.
2. Use only summer blended fuel. Using old fuel left over
from winter may cause damage to the engine or
clogging of the fuel fi lters and injection pump.
See Engine Manufacturers instructions.
OPERATING SPEED
The engine-generator must be run at the correct speed in
order to produce the proper electrical voltage and fre-
quency.
CAUTION: EQUIPMENT DAMAGE
The output voltage should be checked to insure 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 genera-
tor 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 ap-
preciable 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 may vary slightly, the
normal voltage and frequency of the engine-generators
described in this book are approximately as follows, under
varying loads:

The speed of the engine was carefully adjusted at the fac-
tory 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. Whenever making any speed adjustments
check the unit with a voltmeter or tachometer and be sure
the speed is correct.
The engine will govern itself at full speed. Intentionally
overriding the governor and operating the generator at
low voltage may damage both the generator and any load
connected to it. Running the engine at excessively high
speeds results in high voltage, which may signifi cantly
shorten the life of light bulbs and appliances being used,
as well as possibly damaging the engine.
Output voltage should be checked periodically to ensure
continued proper operation of the generating plant and ap-
pliances. If the generator is not equipped with a voltmeter,
it can be checked with a portable meter. Frequency can be
checked by using an electric clock with a sweep second
hand. Timed against a wrist watch or a stop watch the
clock should be correct within +/- 2 seconds.
CONNECTING THE LOADS
The engine-generators covered in this manual were de-
signed for portable use. DO NOT OPERATE INDOORS.
The unit should be stored in a warm dry location. Move the
unit outdoors to a fl at dry location for use.
Applying The Load
Allow the engine to warm up for two or three minutes be-
fore applying any load. This will allow the engine to reach
normal operating temperature and oil to circulate through-
out the engine. A short warm-up time will permit the en-
gine 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 con-
nected to the generator. The loads should be added one
at a time. If a large motor is being started or multiple mo-
tors are being started, they should be started individually
and the largest should be started fi rst.
