INTENDED USES
These engine generator sets have been designed primarily
for portable use. Both 120, 240 and 120/240 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 between the two power feeds not
to exceed 60 amps on either side. 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
inside or in small compartments (such as pickup truck beds)
which can restrict 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 or the bed of a pickup truck. 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 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.
LUBRICATION
Before starting the engine, fill the crankcase to the proper level
with a good quality oil. The recommended grade of oil and
quantity of oil required is listed in the engine operator's
manual shipped with your unit. 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.
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.
1. This generator set was in good order when shipped.
Inspect the power plant promptly after receiving it. If
damage is noted, notify the transportation company
immediately, request proper procedures for filing a
“concealed damage” claim. Title to the equipment
and responsibility for filing a claim rests with you
when a generator is sent F.O.B. shipping point. Only
you can legally file a claim.
2. Before proceeding with the preparation of your new
engine generator set for operation, take a couple of
minutes to insure that the unit you have received is
the correct model and review the specification pages
in this manual to insure that this unit fits your job
requirements.
3. After removing the engine generator from the carton
locate and remove the shipping strap attached to the
generator shock mount. See attached tag for
removal instructions.
LOW OIL LEVEL SHUTDOWN SYSTEM
This Industrial engine/generator set is equipped with a low oil
pressure shutdown system. This low oil pressure system will
automatically stop the engine when the oil pressure becomes
to low. This feature is designed to reduce costly repairs and
downtime.
CAUTION: EQUIPMENT DAMAGE
Allowing the engine to shutdown repeatedly on
low oil level may cause excessive wear which
can be cumulative.
GASOLINE FUEL
Always use a good grade of unleaded fuel with a minimum of
85 octane. Some fuels, called oxygenated or reformulated
gasoline, are gasoline blended with alcohol or ethers.
Excessive amount of there blends can damage the fuel system
or cause performance problems. If any undesirable operation
symptoms occur, use a gasoline with a lower percentage of
alcohol or ether. DO NOT use gasoline containing
methanol. Always insure that the fuel is clean and free of all
impurities.
Page 360706-175
5210-20
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive
when proper precautions are not taken.
Never use fuel that has been stored for an extended period of
time as the fuel will lose it's volatile properties and you will be
left with only the varnish residue. This varnish like substance
will clog the carburetor or injectors 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 fuel tank and replace with fresh fuel
before attempting to start.
BATTERY INSTALLATION
These engine generator sets are shipped with a battery rack,
and battery cables installed. A battery tie down kit is shipped
loose with each unit.
You will need to purchase and install a battery to operate this
engine generator set. A twelve volt battery, group 26 rated at
500 CCA or larger is recommended for this electric start
engine generator set. Follow the battery manufacturers
recommendations for servicing and charging prior to use.
Connect the battery to the electric start system using the
cables provided.
CAUTION: EQUIPMENT DAMAGE
These electric start engines are NEGATIVE GROUND. Use
extreme caution when connecting the battery. Connect the
NEGATIVE battery terminal to GROUND.
4 WHEEL DOLLY KIT
The WL18000 ships with a 4 wheel dolly kit as standard
equipment. 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.
CAUTION: EQUIPMENT DAMAGE
This is a four wheel dolly kit be sure to chock the
wheels properly before operating the generator. Failure to
properly restrict unit movement will allow the unit to move
causing damage to the unit, drop cords or loads.
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.
2. Fuel level, fill as required with clean fresh fuel.
3. Visually check for loose or broken parts.
STARTING
The throttle control on these generators is preset and
locked to operate at 3600 RPM (nominal) with no load
speed set at 3690 RPM. Only a trained service technician
should be allowed to adjust this speed setting. See
“Operating Speed” section for additional information.
NOTICE: ENGINE
These units may not start if the oil is low. The lubricating oil
level must be at the full mark before the engine will start.
For your safety always connect the positive battery cable to
the “bat+” terminal first. Then connect the negative battery
cable to the “bat-” terminal. Make sure all connections are
clean and tight. Reverse the sequence when disconnecting,
disconnect the negative cable first. These engines produce
enough direct current to keep a battery charged under normal
operating conditions, but were not intended to be used as a
battery charger.
WARNING: PERSONAL INJURY
Lead acid batteries produce explosive hydrogen gas
when charging. Keep sparks, flames, and burning
cigarettes away from the battery. Ventilate the area
when charging or using the battery in an enclosed
space. Lead acid batteries contain sulfuric acid, which
causes severe burns. If acid contacts eyes, skin or
clothing, flush well with water. For contact with eyes,
get immediate medical attention.
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 assembly to produce a
DC charging current of about 1 to 3 AMP. This circuit is not
designed to be used as a battery charging circuit to recharge
dead batteries.
ELECTRIC STARTING
1. Turn on the fuel supply.
2. Pull the choke to the full "on" position. 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 5 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
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.
5210-20
Page 4 60706-175
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. Turn key to stop position.
2. Close the fuel shut-off valve. Always shut the
fuel off whenever the engine is stopped to prevent
fuel leakage from carburetor.
3. Before extended storage (over 30 days) certain
precautions must be taken to ensure the fuel
doesn’t deteriorate and clog the fuel system.
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.
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.
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. Because these generators are
externally regulated the voltage is going to remain at a
constant level (about 120/240). The slight variation in speed
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 may vary slightly, the normal voltage
and frequency of the WL18000 are approximately as follows,
under varying loads:
__________________________________________________________________________________________________________________
LOAD vs. OUTPUT
Generator Frequency Voltage
Load Speed 120V
Applied* (RPM) (HZ) Recpt.
__________________________________________________________________________________________________________________
None 3690 61.5 120V
Half 3600 60.0 120V
Full 3510 58.5 120V
__________________________________________________________________________________________________________________
*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 frequency. For
normal usage, the speed setting should not be changed.
Whenever making any speed adjustments check the unit with
frequency meter or tach and be sure the speed is correct.
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.
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. Motors require a much higher amperage to get
them running, generally 5 to 7 times the running amperage.
These engine generator sets are externally regulated by an
automatic voltage regulator. 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.
Page 560706-175
5210-20
Grounding
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 “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
for portable use. DO NOT OPERATE INDOORS. The unit
should be stored in a warm dry location. Move the unit
outdoors to a flat dry location for use.
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.
WARNING: PERSONAL DANGER
A fully isolated, double pole double throw manual
transfer switch must be installed any time a generator is
being connected to an existing distribution system.
1. These engine generator sets are designed for portable
heavy duty commercial use. Receptacles are provided on
the control panel to permit 120 and 240 volt portable
appliances and tools to be plugged directly into them.
Please note that the 3 wire 240 volt receptacle(s) on these
units are designed to power only 240 volt tools. Thereare
2 hots and a ground wire, but no neutral connection, in the
3 wire 240 volt receptacle. A 4 wire receptacle (2 hot, 1
ground, and 1 neutral) has been provided on the control
panel for use in temporary power applications requiring
120/240 volt power. Consult a licensed electrician for
wiring the TemPower plug and connecting it as temporary
service.
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 plug (Nema 14-60P), the matching receptacle is
installed on the control panel.
2. If the generator set is be connected to existing
distribution system a fully isolated manual transfer switch
must be installed. 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.
3. Many homes and construction sites are wired for at
least 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. 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.
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 worldwide
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.
Change the oil
After the first fifty hours of operation the oil should be
changed. For oil change intervals and a complete
maintenance schedule consult the engine manual you
received with your generator. Change engine oil more often
if the engine is operated under heavy load, or in high
ambient temperatures. Generators should be considered
heavy use when determining oil change intervals
a. Remove oil drain plug at base of the engine and
drain the oil with the engine warm.
b. Replace oil drain plug.
c. Change the oil filter.
d. Remove oil filler plug and refill with new oil.
e. Replace filler plug.
Refer to the table in the engine manual for the
proper grade of oil based on your operating
temperature.
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.
5210-20
Page 6 60706-175
Cartridge Air Cleaner
Remove and clean cartridge yearly or after every 400 hours,
whichever occurs first. Service more often if necessary.
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.
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.
Spark Plug
Clean and reset gap at .020" 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
happens reform 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.
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 (15 to 20 minutes). 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.
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 REPLACEMENT 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.
