b. Pour storage additive to fuel tank. Start the engine and allow it to run on the
rich additive mixture until the fuel pump loads up and stalls the engine. The
fuel lines and injector pump are now filled with a preservative mixture.
Always follow the Engine Manufacturer’s latest recommendations for
additives and procedures for long term storage.
c. While the engine is warm drain oil and refill with fresh oil.
d. Remove the fuel injector(s), pour approximately 1/2 ounce (15 cc) of engine
oil into (each) cylinder and crank slowly to distribute oil. Replace fuel
injector(s).
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.
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.
1. 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 may vary slightly, the normal voltage
and frequency of the engine-generators described in this book are approxi-
mately as follows, under varying loads:

2. 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.
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 significantly shorten the life of light bulbs
and appliances being used, as well as possibly damaging the engine.
2. 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.
CONNECTING THE LOADS
1. 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.
a. Receptacles have been provided on the control panel to connect the loads
to. The loads should be applied gradually. 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
b. 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. See “Starting Electric Motors” in
Specification Section.
c. These engine generator sets are inherently self regulating based on engine
speed. 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.
d. 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 combination of receptacles or a single receptacle as long as the
receptacle amperage rating is not exceeded. Both the 120 and 240 volt
receptacles can be utilized at the same time. See Specification Section for
proper load separation.
2. Grounding - All stationary units must be grounded. Drive a 3/4 or 1" copper
pipe or rod into the ground close to the engine-generator set. The pipe must
penetrate moist earth. Connect an approved ground clamp, to the pipe. Run
a number 10 Awg wire from clamp to the generator ground lug or the battery
negative terminal. Do not connect to a water pipe or to a ground used by a
radio system.
The engine-generators covered in this manual were designed for portable use.
DO NOT OPERATE INDOORS. The unit should be stored in a warm dry
location. Move the unit outdoors to a flat dry location for use.
