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 or enclosed areas 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 5500 watt generator. Receptacles A and B are the
two 120 Volt duplex receptacles. Up to 2750 watts at 120
volts (22.9 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 split-phase motors, are very
hard to start and require 5 to 7 times as much current to
start them as to run them.
start and usually require 2 to 4 times as much current to
start them as to run them.
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
Repulsion-Induction (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.

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 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.
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

UNIT PREPARATION
Before your engine generator was shipped from our factory
it was fully checked for performance. The generator was
load tested to its full capacity, and the voltage and
frequency were carefully checked and adjusted.

OPERATING LOCATION
DANGER: DEATH AND DISABILITY
DO NOT operate or install these units inside any
building or structure. These units produce carbon
monoxide on all three of the operating fuels. Carbon
monoxide can kill or disable a person in a very short
time. In addition, never operate these units in a
location that will allow the carbon monoxide (exhaust)
to seep into a building that is occupied.
The engine-generator models covered in this manual were
designed for portable use. The unit should be stored in a
dry location. During a power outage move the unit outdoors
to a flat dry location such as a driveway, concrete pad or
sidewalk for use. We recommend installing the optional
dolly kit or equivalent for ease of handling.
LUBRICATION
Before starting the engine, fill the crankcase to the proper
level with a good quality oil. When filling the crankcase
with oil use the dipstick, there is some trapped oil in the
engine. The recommended grade of oil and quantity of oil
required is listed in the engine operator's manual. The
necessity of using the correct oil, and keeping the crankcase
full cannot be overemphasized. Engine failures resulting
from inadequate or improper lubricant are considered abuse
and are not covered by the generator or the engine
manufacturer's warranty.
WARNING - Never overfill the crankcase with oil. If the
crankcase is overfilled with oil the excess oil will be push out
through the breather resulting in oil in the carburetor and air
filter.
CAUTION – PERSONAL DANGER
NEVER dispose of a battery in a fire. The battery is capable
of exploding.
DO NOT open or mutilate the battery. Released electrolyte
is known to be harmful to the skin and eyes and to be very
toxic.
These engine generator sets are all NEGATIVE ground. Be
very careful not to connect the battery in reverse polarity, as
this may short circuit the battery charging system on the
engine.
CAUTION – A battery presents a risk of electrical shock and
high short circuit current. The following precautions must be
observed when working with batteries.
1. Remove watches, rings and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the battery
posts to be sure they are free of corrosion.
3. Always connect the battery positive cable first and
then connect the battery negative cable. When
removing the battery cables from the battery reverse
the procedure, disconnect the negative cable first and
then the positive cable.
4. Be sure all connections are tight and coat the
terminals and cable end with dialectic grease.
WARNING – The electrolyte is a diluted sulfuric acid that is
harmful to the skin and eyes. It is electrically conductive
and corrosive. The following precautions must always be
taken.
BATTERY INSTALLATION
If you intend to use the power plant’s electric start system,
(required if you are intending to use either LP or NG Fuel)
you will need to purchase a battery to operate it. Units
equipped with a recoil or rope start will operate satisfactorily
without a battery on gasoline only.
Installation and servicing of batteries must be performed or
supervised only by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized personnel
away from batteries.
When installing or replacing batteries, use the proper group/
size starting battery. The battery should be a Maintenance
Free lead acid design. Deep cycle batteries will
this application.
8199-00
not work for
* Always wear full eye protection and protective
clothing
* Where electrolyte contacts the skin, wash off
immediately with water.
* If electrolyte contacts the eyes, flush thoroughly
and immediately with water and seek immediate
medical attention.
* Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to
use a solution of one pound of bicarbonate of soda
(baking soda) to one gallon of water. The
bicarbonate of soda solution is to be added until
the evidence of reaction, foaming, has ceased.
The resulting liquid is to be flushed with water and
the area dried.
Page 4 60707-117
DANGER – Explosive Fire Risk
* Never smoke when near batteries
* Do not cause a flame or spark in the battery area
* Always discharge static electricity from your body
before touching batteries by first touching a
grounded metal surface.
SERVICING BATTERIES
Batteries used on these units may over time lose water. This
is especially true if you are using a trickle charger to maintain
your battery. When refilling the battery with water use only
distilled water. Tap water will shorten the service life of the
battery.
Never fill the battery above the fill line. Over filling above the
upper level line may cause the electrolyte to overflow,
resulting in corrosion to the engine or nearby parts.
Immediately wash off any spilled electrolyte following the
procedure above.
BATTERY CHARGING
Units equipped with electric start have a small flywheel
charger built into the engine flywheel assembly for
recharging the starting battery. This flywheel charger
generates a small AC current that passes through a diode
at the end of the charging lead to produce a DC charging
current of about 1 AMP. This circuit is not designed to be
used as a battery charging circuit to recharge dead
batteries.
LOW OIL LEVEL SHUTDOWN SYSTEM
Briggs & Stratton powered generators - Some engine
generator sets come equipped standard with the Briggs &
Stratton OILGARD warning system.
This low oil warning system will automatically stop the
engine before the oil level reaches an operational danger
point. This feature is designed to prevent costly repairs and
downtime.
The OILGARD system uses a float in the engine crankcase
to sense the oil level. If a low oil level condition should
occur during operation, the float will ground out the
magneto impulse, “killing” the engine. In addition, there is
an indicator light mounted on the engine shroud near the
recoil starter. This light will blink on and off to indicate a low
oil level condition when you are attempting to start the unit.
To get the engine started, you must add the required
amount of oil to the engine crankcase.
Use of the OILGARD system on applications that are
subject to shock, bumping or severe angles of operation (in
excess of 15 degrees) should be avoided. This is
especially true if an unexpected shutdown would cause a
safety hazard or serious inconvenience for the operator.
Honda powered generators - These engine generator
sets come equipped standard with the Honda Oil Alert
System.
The Oil Alert system is designed to prevent damage caused
by an insufficient amount of oil in the crankcase. Before the
oil level in the crankcase can fall below a safe limit, the Oil
Alert system will automatically shut down the engine (the
engine switch will remain in the ON position).
GASOLINE FUEL
When using gasoline always use a good grade of unleaded
fuel. Leaded gasoline may be used if unleaded is not
available. Gasoline containing alcohol, such as gasohol is
not recommended. However, if gasoline with alcohol is
used, it must not contain more than 10 percent Ethanol and
must be removed from the engine during storage. DO NOT
use gasoline containing methanol. Always insure that the
fuel is clean and free of all impurities. See your engine
manual for addition gasoline requirement and warnings.
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when
proper precautions are not taken.
Never use gasoline that has been stored for an extended
period of time as the fuel will lose its volatile properties and
you will be left with only the varnish residue. This varnishlike substance will clog the carburetor and will not burn
properly. The use of a fuel additive, such as STA-BIL, or an
equivalent will minimize the formation of fuel gum deposits.
If a unit has been out of operation for an extended period of
time it is best to drain old fuel from the engine and replace
with fresh fuel before attempting to start.
NOTE: For areas of the country where seasonally blended
fuel is used do not keep and use winter blended fuel in the
summer time. This may cause your unit to vapor lock during
the hot summer use.
LP/NG FUEL INSTALLATION
The information in this instruction is offered to assist you in
providing the proper vapor fuel supply for your engine. This
information is only provided to advise you of the engine’s
requirements and the decisions you must make. In no case
should this information be interpreted to conflict with any
local, state or national code. If in doubt, always follow local
codes.
DANGER: FIRE - PERSONAL INJURY -
All fuel lines must be installed by a qualified fuel
supplier.
The fuel source should be as close as possible to the
outdoor operating location. This will reduce the installation
cost of fuel runs. Connect the fuel supply line to the inlet of
the fuel demand regulator on the unit using a locally
approved flexible fuel line (see table for recommended line
size). The pressure supplied to the demand regulator
must be FOUR TO SIX OUNCES or 7 to 11 INCHES W.C.
(water column). The primary regulator at the fuel supply
must be capable of delivering the proper volume of fuel at
this pressure.
Have your local fuel supplier install a protected fuel
connection at the outside operating location. He should also
install a lockable fuel shut off valve at the connection point.
Have your fuel supplier permanently install a flexible fuel line
to the demand regulator on the engine generator set.
Page 560707-117
8199-00
INSTALLING THE FUEL LINE
DANGER: PERSONAL INJURY
Units that are intended to be run unattended MUST
have an electric fuel solenoid installed. This solenoid
MUST be wired to AUTOMATICALLY turn off the fuel
whenever the engine stops.
Unit location will determine the size of fuel line that is
required to supply the engine with a constant fuel pressure.
Refer to the tables below for fuel line size, and recommended
tank size. For distances of 100 feet and over, a two regulator
fuel system is recommended. This system consisting of a
primary 10-15# regulator at the tank and a 6 ounce
secondary regulator installed about 10 feet from the
generator. You need to run a 3/4 inch line or larger from the
secondary regulator to the engine-generator set. When a two
(2) regulator fuel system is used, a fuel line size of 3/8 inch is
generally adequate for distances up to 300 feet. The line
size from the table below applies to the distance from the
second regulator to the demand regulator. A positive fuel
shut-off device must be installed in the fuel line close to the
engine generator set. This may be either a lockable manual
shut-off valve available from your local fuel installer, or a 12
volt DC fuel solenoid valve. This optional 12 volt DC valve is
available through your local Winco dealer.
The fuel line used to connect the supply line to the demand
regulator must be a locally approved flexible fuel line.
Products used will vary in different regions depending on
availability and local codes. Consult with your local fuel
supplier to insure complete compliance with ALL codes.
engine is in direct relation to the correctness of the fuel
system. Shown below is a block diagram of a typical L.P.
or N.G. installation.
1. Remove the pipe plug from the demand regulator.
2. Connect the flex fuel line to the demand regulator to
the optional fuel solenoid..
DANGER: PERSONAL INJURY
Do not use galvanized pipe in the fuel line runs. The
galvanized coating will become eroded and flake off,
causing possible obstruction or damage to the
regulator or fuel valve. The obstruction could cause an
inoperative engine or an explosive fuel leak.

DANGER! - FIRE - PERSONAL INJURY -
Be careful when sealing gas joints. Excessive sealing
compound can be drawn into the solenoid, regulator or
carburetor causing an engine malfunction or dangerous
fuel leak.

Remember that whichever fuel delivery system or type of
vapor fuel used, the fuel pressure at the demand regulator
installed on the engine generator must be between 4 and 6
oz. (7-11 inches of water column). Any lower pressure and
the unit will starve for fuel under load. Any higher and the
unit will ‘flood’ when attempting to start.
LP TANK SIZING
FROM LP/NG TO GASOLINE
1. With the engine running turn off the LP/NG fuel
supply.
2. Run the engine until it runs out of fuel.
3. Remove the flexible fuel line from the demand
regulator.
4. Reinstall the plastic plug in the regulator.
5. Check to be sure the gasoline fuel valve is off.
6. Fill the gasoline fuel tank.
7. Turn on the gasoline fuel valve.
8. Start the engine.
Optional Dolly Kit (HPS9000 & HPS6000)
An optional dolly kit is available for these engine generator
sets. The dolly kit comes with instructions and parts list.
After installing the dolly kit, file the instructions and parts list
in the back of this manual for future reference. The
HPS12000HE is shipped standard with a dolly kit.
Once above the minimum acceptable size, the size of L.P.
tank used will generally depend on how long you want the

CHANGING FUEL TYPES
These engine generator sets are designed to run on three
different fuels; gasoline, natural gas or LP vapor. They may
be easily changed from one fuel to another.
FROM GASOLINE TO LP/NG
1. With the engine running turn off the gasoline
fuel valve.
2. Run the engine until it runs out of fuel.
3. Remove the pipe plug from the demand
regulator.
4. Install locally approved flexible fuel line.
5. Connect the LP/NG vapor fuel line.
6. All three unit have two different hose fittings on the
top of the demand requlator. One is for LP and one is
for Natural Gas. Make sure the hose is attached to the
proper fitting.
7. Turn on the vapor fuel.
8. Start the engine.
9 . Apply the load to the generator.
INITIAL START UP
Use the following checklist to verify the correct preparation
of the engine generator before starting.
Before Starting always Check:
1. Engine oil, fill as required with correct grade and
quantity. Use the dipstick.
2. Fuel level, fill as required with clean fresh fuel.
3. If you are using LP or NG besure the fuel is turned
on and all connection are tight.
3. Visually for loose parts.
STARTING
The throttle control on these generators is preset and locked
to operate at 3600 RPM (nominal) with no load speed set at
3750 RPM. Only a trained service technician should be
allowed to adjust this speed setting. See “Operating Speed”
section for additional information.
NOTICE: ENGINE START LOCKOUT
This unit will not start if it is low on oil. The lubricating oil
level must be at the full mark before the engine will start.
MANUAL STARTING - Refer to the engine manual for
additional starting, operating, and stopping instructions.
NOTICE: TRI-FUEL STARTING
Tri-Fuel generators operating on vapor fuel, (either LP or
NG) must be started using the electric start system
provided. You cannot hand crank the unit fast enough to
develop the proper vacuum to make the vapor fuel system
work. WHEN USING VAPOR FUEL NEVER USE THE
CHOKE. Use of the choke will prevent the air and fuel
from properly mixing.
Page 760707-117
8199-00
1. Turn on the fuel supply.
2. Move the choke to the full "on" position. A warm
engine will require less choking than a cold engine.
3. Grasp starter grip and pull slowly until starter engages,
then pull cord rapidly to overcome compression,
prevent kickback and start the engine. Repeat if
necessary.
4. When the engine starts, open the choke gradually.
5. The engine should promptly come up to operating
speed.
Electric Starting - If the engine is cold and stiff or if the
battery is not fully charged, starting can be made easier by
slowly hand cranking the engine through the compression
stroke before pushing the starter switch. This permits the
starter to gain momentum before the heavy load of the
compression stroke occurs. This minimizes the drain on the
battery and improves the possibility of starting under such
adverse conditions. Always keep the battery charged, but
especially during cold weather operation.
1. Turn on the fuel supply.
2. Move the choke to the full "on" position (for gasoline
only). A warm engine will require less choking than a
cold engine.
3. Engage the engine start switch briefly to the START
position. The starter life is improved by using shorter
starting cycles with time to cool off between cranking
cycles. Do not operate the starter more than 15
seconds during each minute. Repeat if necessary.
4. When the engine starts, open the choke gradually.
5. The engine should promptly come up to operating
speed.
CAUTION: EQUIPMENT DAMAGE
Never permit the choke to remain on after the engine has
run for a short time. It is not necessary to choke the
engine when it is warm. Avoid over-choking.
STARTING HINTS
NOTE: For areas of the country where seasonally blended
fuel is used do not keep and use winter blended fuel in the
summer time. This may cause your unit to vapor lock during
the hot summer use.
1. Cold weather
a. Use the proper oil for the temperature expected.
b. Use fresh winter grade fuel. Winter grade
gasoline is blended to improve starting. Do not
use summer gasoline.
c. A slightly richer fuel mixture will usually improve
cold starting.
2. Hot weather
a. Use the proper oil for the temperature expected.
b. Use only summer blended gasoline. Using
gasoline left over from winter may cause the unit
to vapor lock.
c. DO NOT over-choke the unit.
STOPPING AND STORAGE
1. Remove the load.
2. Turn off key the on engine to ‘ground out’ the spark
and shut the unit down.
3. Before extended storage (over 30 days) certain
precautions must be taken to ensure the fuel
doesn’t deteriorate and clog the fuel system. Note:
The use of a fuel additive, such as STA-BIL, or an
equivalent, will minimize the formation of gum
deposits during storage. Such an additive may be
added to gasoline in the engine’s fuel tank or to
gasoline in a storage container.
a. Remove the remaining fuel from the fuel tank.
b. Start the engine and allow it to run until all
the fuel in the carburetor and the fuel lines has
been used up and the engine stops.
c. While the engine is warm, drain the oil and
refill with fresh oil.
d. Remove the spark plug, pour approximately
1/2 ounce (15 cc) of engine oil into the cylinder
and crank slowly to distribute oil. Replace spark
plug.
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.
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 approximately as follows, under
varying loads:
__________________________________________________________________________________________________________________
Generator Frequency Voltage
Load Speed 120V
Applied* (RPM) (Hz) Recpt.
__________________________________________________________________________________________________________________
None 3750 62.5 129V
Half 3600 60.0 120V
Full 3540 59.0 115V
__________________________________________________________________________________________________________________
*Portion of plant’s rated output current.
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
LOAD vs. OUTPUT
8199-00
Page 8 60707-117
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.
Lower 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 appliances being used.
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 per
minute.
CONNECTING THE LOADS
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.
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.
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.
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 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
Unit Capabilities (page 3).
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.
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.
WIRING
‘Hard Wiring’ this unit directly into a temporary construction
site electrical system or into a home as a back up 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.
These generators come equipped with a 4 wire 120/240 volt
receptacle designed to power both 120 and 240 volt loads.
There are 2 hots, a neutral, and a ground wire connection in
the 4 wire 120/240 volt receptacle (L14-30R). This
receptacle is protected by a double pole circuit breaker rated
for generator output. Below is a table of the matching plugs
for each of the models, note the 12 kW has two 4-wire plugs.

AND 14-60P 60 AMP 300137
CAUTION: EQUIPMENT DAMAGE
Caution must be used when loading the generator,
overloading either of the 120 volt sides will cause the
breaker to trip, disconnecting all the loads
TEMPORARY SITE'S ELECTRICAL SYSTEM
To connect these units directly to an un-powered, isolated
construction site TemPower panel, have your electrician
connect to the control panel using a 120/240 volt, four wire
twist-lock plug (L14-30P). The use of locking receptacles
and locking plugs provides the convenience of quick
disconnect, for moving, while allowing non electrical workers
to safely reconnect the power. In addition they prevent the
plug from being accidentally removed by bumping or
vibration.
EXISTING ELECTRICAL SYSTEM (Home Standby)
WARNING: PERSONAL DANGER
NATIONAL ELECTRIC CODE REQUIRES a fully isolated,
double pole double throw manual transfer switch be
installed any time a generator is being connected to an
existing distribution system.
NEVER BACK FEED A DRYER OR RANGE 240 VOLT
RECEPTACLE
If the generator set is connected to existing (electrical)
wiring circuits it is permitted only through a fully isolated
manual transfer switch. The transfer switch prevents
damage to the generator and other circuit components if
main line power is restored while the generator is
connected. Installing a transfer switch also permits the use
of normal fusing.
Page 960707-117
8199-00
Many homes and construction sites are wired for at least 60
to 100 Amp entrance service, much greater than the capacity
of these portable generators. When installing the generator
at these sites, a secondary emergency distribution panel may
have to be installed, such as the Emergency Transfer/Service
(ET/S) system available through your Winco dealer. The
emergency distribution panel must be installed by a licensed
electrician according to all applicable codes. The electrician
will move the critical circuits to be powered during the outage
to the emergency panel. Keep in mind only a limited amount
of amperage is available from the generator set. Some circuit
breakers may still have to be turned off to prevent an
overload on the generator during the initial start up. See the
nameplate on your generator for the amperage capabilities of
your unit.
CAUTION: EQUIPMENT DAMAGE
Failure to properly limit and balance the load applied to
the generator will cause the generator to produce low
voltage and may damage the engine generator set. It
may also cause severe damage to the loads connected
to the generator at that time. Improper loading of the
generator set constitutes abuse and will not be covered
by warranty.
Grounding
NOTE - These generators sets are shipped with the ground
bonded to neutral. For an isolated ground system remove the
neutral to ground bond in the receptacle panel. Be sure to
reinstall before using the generator as a stand alone unit.
All 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 No. 10 Awg wire from clamp
to the generator ground lug on the “end cover”. Do not
connect to a water pipe or to a ground used by a radio
system.
ENGINE CARE
If major engine service or repair is required contact an
authorized engine service center. The manufacturer of these
engines has established an excellent world-wide engine
service organization. Engine service is very likely available
from a nearby authorized dealer or distributor. Check the
yellow pages of your local telephone directory under
“Engines-Gasoline” for the closest engine repair center or ask
the dealer from whom you purchased the power plant.
1. Change the oil after the first five hours of operation
and every 50 hours thereafter under normal
operating conditions. Change engine oil every 25
hours of operation if the engine is operated under
heavy load, or in high ambient temperatures.
a. Remove oil drain plug at base of the engine
and drain the oil with the engine warm.
b. Replace oil drain plug.
c. Remove oil filler plug and refill with new oil.
Refer to the table in the engine manual for the
proper grade of oil based on your operating
temperature.
d. Replace filler plug.
2. Checking the Oil Level: The oil level must always be
checked before the engine is started. Take care to
remove any dirt or debris from around the oil fill plug
before removing. Be sure the oil level is maintained.
to the “FULL” mark on the dipstick, DO NOT OVER
FILL
3. Cartridge Air Cleaner - Remove and clean cartridge
yearly or after every 25 hours, whichever occurs first.
Service more often if necessary. Clean by tapping
gently on flat surface. If very dirty, replace the cartridge
using only original equipment parts available at any
engine service center.
Do not use petroleum solvents, such as kerosene, to
attempt to clean the cartridge. They may cause
deterioration of the cartridge. DO NOT OIL
CARTRIDGE, DO NOT USE PRESSURIZED AIR TO
CLEAN OR DRY CARTRIDGE.
4. Dual Element Air Cleaner - Clean and re-oil foam pre-
cleaner at three month intervals or every 25 hours,
whichever occurs first. Service more often under dusty
conditions.
a. Remove knob and cover.
b. Remove foam pre-cleaner by sliding it off the
paper cartridge.
c. Wash foam pre-cleaner in kerosene or liquid
detergent and water
d. Wrap foam pre-cleaner in cloth and squeeze dry.
e. Saturate foam pre-cleaner in engine oil.
Squeeze to remove excess oil.
f. Install foam pre-cleaner over paper cartridge.
Reassemble cover and screw down tight.
Replace the cartridge included with Dual Element Air
Cleaner yearly or every 100 hours. Service more often
if necessary.
5. Spark Plug - Clean and reset gap to the proper gap
every 100 hours of operation. Do not blast clean spark
plug. Clean by scraping or wire brushing and washing
with a commercial solvent. Poor spark will occur if
terminal does not fit firmly on spark plug. If this
happensreform the terminal to fit firmly on spark plug
tip.
GENERATOR CARE
Proper care and maintenance of the generator is necessary
to insure a long trouble free life.
1.Exercising The Generator - The generator should be
operated every three to four weeks. It should be
operated for a period of time sufficient to warm the
unit up and to dry out any moisture that has
accumulated in the windings. If left, this moisture can
cause corrosion in the winding. Frequent operation of
the engine generator set will also insure that the set is
operating properly should it be needed in an
emergency.
8199-00
Page 10 60707-117
2.Generator Maintenance - Any major generator
service including the installation or replacement of
parts should be performed only by a qualified
electrical service technician. USE ONLY FACTORY
APPROVED REPAIR PARTS.
a. Bearing - The bearing used in these generators is
a heavy duty double sealed ball bearing. They
require no maintenance or lubrication.
b. Receptacles - Quality receptacles have been utilized.
If a receptacle should become cracked or otherwise
damaged, replace it. Using damaged or cracked
receptacles can be both dangerous to the operator
and destructive to the equipment.
CLEANING
Remove dirt and debris with a cloth or brush. DO NOT use
high pressure spray to clean either the engine or the
generator. This high pressure spray could contaminate the
fuel system and the generator components.
1. Keep the air inlet screen on both the engine and
generator free of any dirt or debris to insure proper
cooling. At least yearly remove the blower housing on
the engine and clean the chaff and dirt out of the engine
cooling fins and flywheel. Clean more often if
necessary. Failure to keep these areas clean may
cause overheating and permanent damage to the unit.
2. Periodically clean muffler area to remove all grass, dirt
and combustible debris to prevent a fire.
3. On engine mufflers equipped with spark arresters, the
spark arrester must be removed every 50 hours for
cleaning and inspection. Replace if damaged.
