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.
Whenever 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 significantly 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 circu-
late 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 volt-
age and amperage requirements on their individual
nameplates. When in doubt, consult the manufac-
turer or a local electrician. The nameplate amperage
rating for electric motors can be misleading. See a
further explanation under “Starting Electric Motors”
in Unit Capabilities (page 4).
These engine-generator sets are inherently self reg-
ulating 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. 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.
GROUNDING
All units must be grounded. Drive a 3/4” or 1” copper
pipe or rod into the ground close to the engine-gen-
erator set. The pipe must penetrate moist earth.
Connect an approved ground clamp to the pipe.
Run a no. 10 Awg wire from clamp to the generator
ground lug on the receptacle panel. Do not connect
to a water pipe or to a ground used by a radio sys-
tem. The engine-generators covered in this manual
were designed primarily for portable use.
WARNING: PERSONAL DANGER
DO NOT OPERATE THIS GENERATOR INDOORS.
The unit should be stored in a warm dry location.
During a power outage, move the unit outdoors to a
flat dry location such as a driveway or sidewalk .
WIRING
Plug your tools such as drills, saws, blowers, sump
pump and other items to be powered directly into
the generator receptacles. Before plugging in all the
tools and cord sets, recheck the rating of the genera-
tor set. Be sure it can handle the intended load and
is compatible with the voltage, phase, and current
ratings. ‘Hard Wiring’ this unit directly into a tem-
porary construction site electrical system is NOT A
SIMPLE DO-IT-YOURSELF JOB. For your safety,
all wiring must be done by a qualified electrician and
conform to the National Electric Code and com-
ply with all state and local codes and regulations.
Check with local authorities before proceeding.
