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.

c.

DO NOT over-choke the unit.

STOPPING AND STORAGE

1.

Turn key to stop position.

2.

Close the fuel shut-off valve. Always shut the
fuel off whenever the engine is stopped to prevent
fuel leakage from carburetor.

3.

Before extended storage (over 30 days) certain
precautions must be taken to ensure the fuel
doesn’t deteriorate and clog the fuel system.

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
refill with fresh oil.

d.

Remove the spark plug, pour approximately
1/2 ounce (15 cc) of engine oil into the
cylinder and crank slowly to distribute oil.
Replace spark plug.

e.

Clean dirt and chaff from cylinder,
cylinder head fins, blower housing, rotating
screen and muffler areas.

f.

Store in a clean and dry area.

Note: The use of a fuel additive, such as STA-BIL, or an
equivalent, will minimize the formation of gum deposits during
storage. Such an additive may be added to gasoline in the
engine’s fuel tank or to gasoline in a storage container.

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 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. Because these generators are
externally regulated the voltage is going to remain at a
constant level (about 120/240). The slight variation in speed
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 may vary slightly, the normal voltage
and frequency of the WL18000 are approximately as follows,
under varying loads:

*Portion of plant’s rated output current.

The speed of the engine was carefully adjusted at the factory
so that the generator produces the proper frequency. For
normal usage, the speed setting should not be changed.
Whenever making any speed adjustments check the unit with
frequency meter or tach and be sure the speed is correct.

Output voltage should be checked periodically to ensure
continued proper operation of the generating plant and
appliances. 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 per minute.

CONNECTING THE LOADS

Applying The Load

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 circulate throughout the
engine. A short warm-up time will permit the engine to work
more efficiently 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 first.

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 .

Most electric tools and appliances will have the voltage and
amperage requirements on their individual nameplates.
When in doubt consult the manufacturer or a local electrician.
The nameplate amperage rating for electric motors can be
misleading. Motors require a much higher amperage to get
them running, generally 5 to 7 times the running amperage.

These engine generator sets are externally regulated by an
automatic voltage regulator. The engine governor will
automatically adjust itself to the load. No harm to the
generator will result if it is operated with no load connected.

Proper utilization of the receptacles located on the control
panel is necessary to prevent damage to either the
receptacles or the generator. The generator is a limited
source of electrical power, therefore pay special attention to
the receptacle and generator ratings. The nameplate rating
can be obtained through a single receptacle as long as the
receptacle amperage rating is not exceeded.
