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 3720 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 lu-
bricating oil level must be at the full mark before the
engine will start and run.
BASIC OPERATION
Manual starting - Refer to the engine manual for ad-
ditional starting, operating, and stopping instructions.
1. Pull the choke rod out to the choke position.
2. Move the on/off lever to the on position.
3. Pull the starter grip lightly until resistance is felt,
then pull briskly.
NOTICE:
Do not allow the starter grip to snap back against
the engine. Return it gently to prevent damage to the
starter.
4. If the choke rod was pulled to the CLOSED posi-
tion to start the engine, push it to the OPEN posi-
tion as soon as the engine warms up enough to run
smoothly.
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-chok-
ing.
STARTING HINTS
1. Cold weather
a. Use the proper oil for the temperature expect-
ed.
b. Use fresh winter grade fuel. Winter grade
gasoline is blended to improve starting. Do not
use summer gasoline.
c. A slightly richer fuel mixture will usually improve
cold starting.
2. Hot weather
a. Use the proper oil for the temperature expect-
ed.
b. Use only summer blended gasoline. Using
gasoline left over from winter may cause the
unit to vapor lock.
STOPPING AND STORAGE
1. Move the on/off lever to the off position.
2. Before extended storage (over 30 days) certain
precautions must be taken care of to ensure the fuel
doesn’t deteriorate and clog the fuel system. Note:
The use of a fuel additive, such as STA-BIL or an
equivalent will minimize the formation of gum depos-
its during storage. Such an additive may be added
to gasoline in the engines fuel tank or to gasoline in
a storage container.
a. Remove the remaining fuel from the fuel tank.
b. 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.
c. While the engine is warm, drain the oil and
refi ll with fresh oil.
d. Remove the spark plug, pour approximately
1/2 ounce (15 cc) of engine oil into the cylind-
er and crank slowly to distribute the oil. Re-
place the spark plug.
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 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 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:
