odorless and deadly gas that must be mixed with fresh air.
a. Operate only in well ventilated areas.
b. Never operate indoors.
c. Never operate the unit in such a way as to allow
exhaust gases to seep back into closed rooms (i.e.
through windows, walls or floors).
4.NOISE HAZARD - Excessive noise is not only tiring, but
continual exposure can lead to loss of hearing.
a. Use hearing protection equipment when working
around this equipment for long periods of time.
b. Keep your neighbors in mind when permanently
installing this equipment.
5.CLEANLINESS- Keep the generator and surrounding
area clean.
a. Remove all grease, ice, snow or materials that create
slippery conditions around the unit.
b. Remove any rags or other material that could create
potential fire hazards.
c. Carefully wipe up any gas or oil spills before starting
the unit.
d. Never allow leaves or other flammable material to
build up around the engine exhaust area.
6.SERVICING EQUIPMENT- All service, including the
installation or replacement of service parts, should be
performed only by a qualified technician.
a. Use only factory approved repair parts.
b. Do not work on this equipment when fatigued.
c. Never remove the protective guards, cover, or
receptacle panels while the engine is running.
d. Use extreme caution when working on electrical
components. High output voltages from this
equipment can cause serious injury or death.
e. Always avoid hot mufflers, exhaust manifolds, and
engine parts. They all can cause severe burns
instantly.
f. Installing a home-standby generator is not a “do-it-
yourself” project. Consult a qualified, licensed
electrician or contractor. The installation must comply
with all national, state, and local codes.
a. Do not refuel when the engine is running or hot. Allow
the engine to cool at least two minutes before refueling.
b. Keep fuel containers out of reach of children.
c. Do not smoke or use open flame near the generator set
or fuel tank.
d. Keep a fire extinguisher nearby and know its proper
use. Fire extinguishers rated ABC by NFPA are
appropriate.

BASIC INFORMATION
INTENDED USES
These engine generator sets have been designed primarily
for portable use. Both 120 and 240 volt AC receptacles are
provided in the 'control panel' to plug in your loads (lights,
portable tools, and small appliances). These units are dual
wound generators, therefore the 120 Volt loads must be
equally split with 1/2 of the rated capacity available on each
of the two 120 Volt circuits. See unit capabilities for further
explanation.
These portable units require large quantities of fresh air for
cooling of both the engine and the generator. Fresh air is
drawn from both the engine end and the generator end and
is exhausted at the center of the unit. For safety, long life
and adequate performance, these units should never be run
in small compartments without positive fresh air flow.
RESTRICTED USES
DO NOT remove from the cradle assembly. Removal of the
generator from the cradle assembly may cause excessive
vibration and damage to the engine generator set.
DO NOT install and operate these portable generators in a
small compartment., i.e. generator compartment of vehicles,
motor homes or travel trailers. These compartments will not
allow enough free flow fresh air to reach the engine
generator set for cooling and will cause the unit to overheat
damaging both the engine and the generator. Small
compartments will also develop hot spots where there is
very little air flow and may cause a fire.
DO NOT attempt to operate at 50 cycles. These units are
designed and governed to operate at 60 Cycles only.
UNIT CAPABILITIES
Generator Connections - The diagram below represents a
typical 4000 watt generator. Receptacles A and B are the
two 120 Volt duplex receptacles. Up to 2000 watts at 120
volts (16.6 Amps) can be taken from the generator at each
of the receptacles. This generator produces 120 and 240
volt, 60 Hz (Hertz), AC (Alternating Current).
CAUTION: EQUIPMENT DAMAGE
CAUTION MUST BE EXERCISED TO PREVENT
OVERLOADING EITHER OF THE GENERATORS
120 VOLT OUTPUT CIRCUITS (A OR B).
Check the appliance or tool nameplates for the current and
voltage to insure compatibility. Remember that power taken
from receptacle C reduces the power available at both A and
B. Any remaining 120 volt loads should be equally divided
between A and B. Failure to split the load will cause
permanent damage to the stator. Although circuit breakers are
provided, damage due to overloading constitutes abuse and
will not be warranted. Refer to the generator nameplate for
your unit's capabilities.
Starting Electric Motors - Electric motors require much more
current (amps) to start them than to run them. Some motors,
particularly low cost
and require 5 to 7 times as much current to start them as to
run them.
require 2 to 4 times as much current to start them as to run
them.
usually require 1 1/2 to 2 1/2 times as much to start them as to
run them.
Most fractional horsepower motors take about the same
amount of current to run them whether they are of RepulsionInduction (RI), Capacitor (Cap), or Split-Phase (SP) type. The
chart below shows the approximate current required to start
and run various types and sizes of 120 volt 60 cycle electric
motors under average load conditions.
HP AMPS SP CAP RI
The figures given above are for an average load such as a
blower or fan. If the electric motor is connected to a hard
starting load such as an air compressor, it will require more
starting current. If it is connected to a light load, or no load
such as a power saw, it will require less starting current. The
exact requirement will also vary with the brand or design of the
motor.
Self-excited generators respond to severe overloading
differently than the power line. When overloaded, the engine
is not able to supply enough power to bring the electric motor
up to operating speed. The generator responds with high initial
starting current, but the engine speed drops sharply. The
overload may stall the engine. If allowed to operate at very low
speeds, the electric motor starting winding will burn out in a
short time. The generator winding might also be damaged.
Capacitor motors are easier to start and usually
Repulsion Induction motors are the easiest to start and

CAUTION: EQUIPMENT DAMAGE
RUNNING THE GENERATOR SET UNDER THESE
CONDITIONS MAY RESULT IN DAMAGING THE
GENERATOR STATOR AS WELL AS THE MOTOR
WINDING.
Because the heavy surge of current required for starting
motors is required for only an instant, the generator will not be
damaged if it can bring the motor up to speed in a few
seconds of time. If difficulty is experienced in starting motors,
turn all other electrical loads off and if possible reduce the load
on the electric motor.
