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 cir-
culate 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 5).
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 /4” or 1” copper
pipe or rod into the ground close to the engine-gen-
erator set. The pipe must penetrate moist earth. Con-
nect 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 system.
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
generator 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
temporary 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 comply
with all state and local codes and regulations. Check
with local authorities before proceeding.
1. These engine generator sets are designed for
portable heavy duty commercial use. Receptacles
are provided in the end cover to permit your 120
volt loads to be plugged directly in to. On this size of
generator no provisions have been made for plugging
into an existing building wiring. Because the 120
volt receptacle is a GFCI design, connecting to any
wiring system with a neutral to ground jumper in it will
cause the GFCI to trip. If you desire to connect to
an existing wiring system consult a licensed electri-
cian before wiring.
