damage or destruction of the equipment and possible
personal injury.
______________________________________________________
1.ELECTRIC SHOCK- The output voltage present in this
equipment can cause a fatal electric shock. This equipment
must be operated by a responsible person.
a.Do not allow anyone to operate the generator
without proper instruction.
b.Guard against electric shock.
c.Avoid contact with live terminals or receptacles.
d.Use extreme care if operating this unit in rain or
snow.
e.Use only three-prong grounded plugs and
extension cords.
f.Be sure the unit is properly grounded to an
external ground rod driven into the earth.
2.FIRE HAZARD- Gasoline and other fuels always present a
hazard of possible explosion and/or fire.
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.
e.Store fuel only in an approved container, and
only in a well-ventilated area.
3.DEADLY EXHAUST GAS - Exhaust fumes from any
gasoline engine contain carbon monoxide, an invisible,
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 tobuild 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.
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.
WINCO PORTABLE SERIES

BASIC INFORMATION
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).
The WINCO High Performance series generators have the
EXTRA Heavy FULL POWER winding to allow the use of all
the power available from the engine at either 120 Volts, 240
Volts or any combination of the 120 or 240 volts. You are
not restricted to splitting up your large 120 Volt loads or
choosing to power them OR a 240 Volt load. There are no
switches or connectors to change. Simply plug in and use
the power without being concerned about overloading the
generator winding as long as the load doesn't exceed the
size of the generator.
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 and vice versa.
Starting Electric Motors
Electric motors require much more current (amps) to start
them than to run them. Some motors, particularly low cost
split-phase motors, are very hard to start and require 5 to 7
times as much current to start them as to run them.
Capacitor motors are easier to start and usually require 2 to 4
times as much current to start them as to run them.
Repulsion Induction motors are the easiest to start and
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.
RUNNING STARTING AMPS
HP AMPS SPCAPRI
1/6 3.2 16 TO 22 6 TO 13 5 TO 8
1/4 4.5 22 TO 32 9 TO 18 7 TO 12
1/3 5.2 26 TO 3510 TO 21 8 TO 17
1/2 7.2 NOT MADE14 TO 2911 TO 18
113.0 NOT MADE26 TO 5220 TO 33
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.
CAUTION: EQUIPMENT DAMAGE
RUNNING THE GENERATOR SET UNDER THESE
CONDITIONS MAY RESULT IN DAMAGING THE
GENERATOR STA TOR 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.
UNPACKING
CAUTION: EQUIPMENT DAMAGE
THIS UNIT HAS BEEN SHIPPED WITHOUT OIL. Failure to
maintain the engine oil at the proper level will result in serious
engine damage.
When you unpack your new ENGINE GENERATOR be sure to
remove all the information sheets and manuals from the
carton.
