INTENDED USES
1. These engine generator sets have been designed
primarily for portable use. Receptaclesare provided
inthe control panelon the generatorfor you to plug
inyour loads(portableappliances and tools). These
generators aredesignedwith full powercapabilities.
See unit capabilities for further explanation.
2. These units require large quantities of fresh air for
cooling of boththe engineand thegenerator. Fresh
air is drawn from both the engine end and the gen-
eratorend and isexhausted at the center of the unit.
For safety, long life and adequate performance,
these units should never be run in small compart-
ments without positive fresh air flow.
RESTRICTED USES
1. DO NOT removefrom the cradle assembly. Remov-
al of the generator from the cradle assembly may
causeexcessivevibration and damagetothe engine
generator set.
2. DO NOT install and operate these portable genera-
tors in small compartment. (i.e. generator compart-
ment of vehicles, motor homes, or travel trailers)
These compartmentswill not allow enough free flow
fresh air to reachthe engine generator set for cool-
ingand will allow the unit tooverheatdamaging both
the engine and the generator. Small compartments
will also develop hot spots where there isvery little
air flow and may cause
a fire.
3. DO NOT attempt to operate this unit at 50 cycles.
These unitsare designed and are governed to oper-
ate at 60 Cycles only. Special unitsare available for
50 cycle operation.
UNIT CAPABILITIES
1. Generator Connections - These generators are
equipped with a patented full power feature. This
feature is designed to give the owner full rated
generator output from a SINGLE 120 volt outlet or
a SINGLE 240 volt outlet without the necessity of
having to carefully balance this 120volt load. Con-
ventional generators require splitting the 120 volt
loads and balancing them on two separate power
leads inorder to fully utilize the rated output of the
conventional generator.
Full Powerwindings use extra heavy wire so that
itcan safely carry theentire loadon asingle 120volt
circuit. This eliminates the needtosplit and balance
the 120 volt load to avoid damaging the armature.
The operator using this generator hasthe entire out-
put availablefrom asingle 120volt circuit or asingle
240 volt circuit or acombinationof 1201240 volts cir-
cuits as long as the total load does not exceed the
engine power.

SPECIFICATlONS (continued)
2. Starting Electric Motors - Electric motors require
much morecurrent (amps)to start them than to run
them. Some motors,particularly lowcost split-phase
motors arevery hardto start and require5to 7times
as much current to start them as to run them. Ca-
pacitor motors are easier to start and usuallyrequire
2 to 4 time as much current to start then as to run
them. RepulsionInductionmotorsare the easiest to
start and usually require 11/2 ,to 2% time 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 ap-
proximate current required to start and run various
types of sizes of 120 volt 60 cycle electric motors
under average load conditions.

1 13.0 NOTMADE 26TO52 20TO33
The figures givenabove are for average load such
as a bloweror 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 isconnected
to a light load, or no load such as a power saw, it
will require less starting current. The exact require-
ment will also vary with the brand or design of the
motor.
For 240 volt motor, the "running" current is half
as much as shown for the 120 volt motors of the
same size. Some dual voltage 1201240 volt motors
are difficult to start on 240 volts when driven by en-
ginelgeneratorsand can bestarted moreeasily when
connectedtooperateon 120volts.This isparticularly
true of "capacitor start-induction run" motors.
Sometimesa240 volt motorwhich cannot bestarted
on the 240 volt circuit of a 1201240volt generator can
be started on a 120 volt circuit and then quickly
switchedtothe240 volt circuit after is isstarted.This
can be done inapplications where the motor is man-
ually controlled and is started under "no load" con-
ditions.
A self-excited generator responds differently to
severeoverloading than a transformer connected to
a power line. To illustrate, suppose that a 240 volt
5 H.P. "capacitor start-InductionRun" motor iscon-
nectedto asmall transformerthat would not be able
to supply enough powerto bringthe motor uptoop-
erating speed. It would be very severely overloaded
and probably would burn out in a short time. The
motor might also be damaged. When this motor is
connected to a self-excited4000 watt generator, its
output voltage dropsto practically zero. Thus, there
isvirtually no load on the generator or the engine,
and no harm isdone to it either. Underthese condi-
tions the motor may revolve a few times when it is
first turned on, and then stop.
On the other hand, supposean electric motorthat
requiresjust a littlemore output then the generator
can produceisconnectedto it. Itwill run but will not
reacha high enough speed for the centrifugal switch
to disconnect the starting winding. The generator
output voltage, instead of being 120, may drop to 70
or 80 volts. RUNNING THE GENERATOR UNDER
THESE CONDITIONS MAY RESULT IN BURNING
OUT THE GENERATOR ARMATURE AS WELL AS
THE MOTOR WINDINGS.
Becausethe 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 dif-
ficulty is experienced in starting motors, turn all
other electrical loads off and if possible reducethe
load on the electric motor.
3. Motor Starting Capacity - listed below you will find
the motor starting capability of your engine genera-
tor set.
Trying to start a larger motor or a higher code (ie
J or K) motor may result indamageto boththe gen-
erator and the electric motor, especially 120 volt
motors.

PREPARATlON INSTRUCTIONS (continued)
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 careful-
ly checked and adjusted.
1. Lubrication - Beforestarting the engine, fill the crank-
case to the proper level with a good quality oil. The
recommended grade of oil and quantity of oil re-
quired is listed in boththe engine operators manual
and in the specifications section (page B1) of this
manual.
The importanceof usingthe correct oil, and keep-
ing the crankcase full cannot be overemphasized.
Engine failures resulting from inadequate or im-
proper lubricant are considered abuse and are not
covered by Energx or the engine manufacturer's
warranty.
2. Gasoline fuel - When using gasoline always use a
good grade of unleaded fuel. Leaded gasoline may
be use if unleadedis not available.Gasolinecontain-
ing alcohol, such as gasohol is not recommended.
Howeverif gasolinewith 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.
FIRE DANGER
Gasoline and its fumes are VERY ex-
plosive when proper precautions are
not taken.
a
Never usegasolinethat has been storedfor an ex-
tended period of time as the fuel will lose it volatile
properties and you will be left with only the varnish
residue.This varnish likesubstancewill clogthe car-
buretor and will not burn properly.The useof a fuel
additive, suchas STA-BIL,or an equivalent, will mini-
mize the formation of fuel gum deposits.If a unit has
beenout of operation for an extendedperiodof time
its best to drain old fuel from the engine and replace
with fresh fuel before attempting to start.
3. Battery Installation and Care - All electric start
enginegeneratorsets are shippedwith a batteryrack
kit for customer installation. This kit consists of a
battery rack, battery tie down, battery cables and in-
struction sheet for installation. After installing the
battery rack, file the instruction sheet inthe back of
this manual for future reference.
If you intendto use the power plant's electric start
system,you will needto purchaseand installa bat-
tery to operateit. Unitsequippedwith a recoilor rope
start will operate satisfactorily without a battery. A
twelve volt battery group U1 rated at 190 CCA or
larger is recommendedfor this electric start engine
generatorset. Followthe battery manufacturers rec-
ommendations for servicing and charging prior to
use. Connect the batteryto the electric start systems
using the cables provided.
These electric start engines are NEGA-
TIVE GROUND. Use extreme caution
when connectingthe batterytoconnect
the NEGATIVE battery terminal to
Foryour safety always connect the positive bat-
tery terminal to the "bat
+ " terminal first. Then con-
nect the negative battery terminal tothe "bat
- " ter-
minal. Make sure all connections are clean and
tight. Reverse the sequence when disconnecting,
disconnect the negative cable first. These engine
produce enough direct current to keep batteries
charged under normal operating conditions, but
they are not intendedto be usedas battery charger.
A PERSONNEL DANGER
Lead acid batteries produce explosive
hydrogen gas when charging. Keep
sparks, flames, and burning cigarettes
. away from the battery. Ventilate the
area when chargingor usingthe battery
inan enclosedspace. Lead acid batter-
iescontain sulfuric acid, which causes
severe burns. If acid contacts eyes, skin
or clothing, flush well with water. For
contact with eyes, get immediate med-
ical attention.
Generators, when installed for standby purposes,
must be run periodically (at least once a month) for
a minimum of 30 minutes to keep the battery
charged. A trickle charger can also be use to keep
the battery fully charged.The trickle chargershould
be a taper charger (usually
2 amps max). With an
taper style charge as the battery reaches is max-
imum chargecapacity, the chargercurrent tapers to
nearzero and maintainsthe batteryin afully charged
condition. Manual type charges with fixed or con-
stant charging rates are not recommended,sincethe
battery will be overcharge, permanently damaging
the battery.
5. Optional Dolly Kit - An optionaldolly kit availablefor
this engine generator set. The dolly kit comes with
instructions and parts list. After installing the dolly
kit,file the instructions and parts list inthe back of
this manual for future reference.

BASIC OPERATION
INITIALSTART UP - Usethe following checklist to verify
the correct preparationof your engine generator before
starting.
On All Units Check:
1. Engine oil, fill as required with correct grade and
quantity.
2. Check fuel level and fill as requiredwith clean fresh
fuel.
3. Visually check unit for loose .parts.
4. Battery connections clean and tight on the electric
start units.
5. Proper battery voltage and CCA rating.
6. Battery fully charged.
BASIC OPERATING CONTROLS - Now that you have
completed the initial start up checklist, you are ready
to start and operate your new engine generator set.
Before starting read through the next section which
details whats on the control panel.

STARTING AND STOPPING - The throttle control on
these generatorsispresetand lockedtooperateat 3600
RPM (nominal)with no load speed set at 3690 RPM. On-
ly atrained service technician should be allowed to ad-
just this speed setting. See "Operating Speed" section
for additional information.
1. Manualstarting - Refer to the engine manual for addi-
tional starting,operating, and stopping instructions.
A. Turn on the fuel supply.
B. Move the choke to the full on position. A warm
enginewill require lesschokingthan acold engine.
C. Grasp starter grip and pull slowly until starter
engages, then pullcord rapidly to overcomecom-
pression, prevent kickback and start the engine.
Repeat if necessary.
D. When the engine starts, open the chokegradually.

2. ElectricStarting - If engine iscold and stiff or if bat-
tery isnot fully charged, starting can be madeeasier
byslowly handcrankingtheenginethrough the com-
pression stroke before pushing the starter button.
This permits the starter to gain momentum before
the heavy load of the compression stroke occurs,
minimizing drain on the battery and ensuring start-
ing under such adverse conditions. Keepthe battery
fully charged, especially during cold weather oper-
ation
A. Turn on the fuel supply.
B.Move the choke to the full on position. A warm
engine will require less choking than a cold en-
gine.
C.Depress the starter switch. The best starter life
is provided by using short starting cycles of sev-
eralseconds. Do notoperatethe starter morethan
15 seconds each minute.
D .When the enginestarts,open the chokegradually.
E .The engine should promptlycomeupto operating
speed.
3. Starting Hints
A. Cold weather
1. Be sureto usethe properoil for the temperature
expected.
2 .A warm battery has much more starting capaci-
ty than a cold battery.
3.Use fresh winter grade fuel. Winter gradegaso-
linehas higher volatility to improvestarting. Do
not use gasoline left over from summer.
4. A slightly richerfuel mixturewill usuallyimprove
cold starting.
B. Hot weather
1. Be sure to use the proper oil for the tempera-
ture expected.
2. Use only summer blended gasoline. Using
gasoline left over from winter may cause the
unit tovapor lock, becauseof the highervolatili-
ty of the winter fuel.
3. DO not over choke the unit.
4. Stopping and Storage
A.For gasoline units depress the stop switch.
B.Close the fuel shut-off value. Always shut the
fuel off when ever the engine isstopped to pre-
vent fuel leakage from carburetor.
C. Beforeextended storage (over 30 days) certain
precautions must be take 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 forma-
tion of fuel gum deposits during storage. Such
an additivemay be addedto gasoline in the fuel
tank of the engine, or to gasoline in a storage
container.
1. Remove the remaining fuel from the fuel
tank.

BASIC OPERATION (continued)
2.Start the engine and allow it to run until all the
fuel inthe carburetor and the fuel lines has been
used up and the engine stops.
3. Whilethe engine iswarm drainoil and refillwith
fresh oil.
4. Remove the spark plug, pour approximately '/2
ounce (15cc) of engine oil into the cylinder and
crank slowly to distribute oil. Replace spark
plug.
5.Cleandirt and chaff from cylinder, cylinder head
fins, blower housing, rotating screen and muf-
fler areas.
6.Store in a clean and dry area.
OPERATINGSPEED -Theengine-generatormust be run
at the correct speed inorderto producethe properelec-
trical voltage and frequency.
The output voltage should be checked
to insurethe generatorisworking prop-
A
erly prior to connecting a load to the
generator. Failuretodo so could result
in damage to equipment plugged into
the unit and possible injuryto the indi-
vidual.
1. All engines have a tendency to slow down when a
load is applied.The governoron theengine isdesigned
to holdthe speed nearlyconstant.When the electrical
load connected to the generator is increased, 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 ina slightly lowervoltage when the gen-
erator is loaded to its full capacity than when run-
ning no load. The slight variation inspeed also affects
the frequency of the output current. This frequency
variation has no appreciableeffect inthe operation of
motors, lights and most appliances. However, elec-
tronic equipment and clockswill 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-generatorsdescribed inthis book are approx-
imately as follows, under varying loads:
LOAD vs. OUTPUT
Generator Frequency Generator voltage
Load Speed (Hz) 120V 240V
Applied* (RPM) Recpt. Recpt.
None 3690 61.5 129V 258V
Half 3600 60.0 120V 240V
Full 3510 58.5 115V 230V
speed setting shouldnot be changed. If the generator
is being run continuously on a very light load, it is
often advisable to lower the operating speed slight-
ly. Whenever making any speed adjustments check
the unit with a voltmeter or tachometer and be sure
the speed is neither too high or low.
Unlessthe engine isequipped with the automatic
conserver assembly the engine must be run at the
specified speed at all times. Lowervoltage may dam-
age both the generator and any load connecting to
it. Running the engine at excessively high speeds
results in high voltage, which may significantly
shorten the life of appliances being used.
3.Output voltage should be checked periodically toen-
sure continued proper operation of the generating
plant and appliances. If the generator is not equip-
ped with a voltmeter, it can be checked with a por-
table 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
+ 1 - 2 seconds.
CONNECTING THE LOADS
1 .ApplyingThe Load - Allow the engineto warm up for
two or three minutes before applying any load. This
will allow the engineto reach normaloperatingtemp-
erature 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.
A. Receptacles have been provided on the control
panel to connect the loads to. The loads should
be applied gradually. 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.
Keepthe generator load within the gen-
erator and receptaclenameplaterating.
Overloadingmay cause damage to the
9. Most electric tools and appliances will have the
voltage and amperage requirements on their in-
dividual nameplates. When in doubt consult the
manufactureror a localelectrician.The nameplate
amperage rating for electric motors can be mis.
leading,see Starting Electric Motors insection B.
C. These engine generator sets are inherently self
regulating based on engine speed. The engine
governorwill automaticallyadjust itself tothe load.
No harm tothe generator will result if it is run with
no load connected.

2. The speed of the engine was carefully adjusted at
the factory so that the generator produces the prop-
er voltage and frequency. For normal usage, the

BASIC OPERATlON (continued)
D. Proper utilization of the receptacles located on
the control panel is necessary to prevent dam-
age to either the receptacles or the generator.
The generator is a limited source of electrical
power, therefore pay special attention to the
receptacleand generator ratings.The nameplate
rating can be obtained through a combinationof
receptaclesor a single receptacle as long as the
receptacleamperage rating,isnotexceeded. Both
the 120 and 240 volt receptacles can be utilized
at the same time. See section B for proper load
separation.
2. Grounding - All units must be grounded.
A. Drive a 314 or 1" copper pipe or rod into the
ground close to the engine-generator set. The
pipe must penetrate moist earth.Connect an ap-
proved ground clamp, to the pipe. Run a no. 10
Awg wire from clamp to!the generator ground lug
or the battery negativeterminal. Do not connect
to a water pipe or to a ground used by a radio
system.
B. The OILGARD system uses a float in the engine
crankcase to sensethe oil level. If a low oil level
condition shouldoccur during operation,the float
will ground out the magnetoimpulse,"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 conditionwhen you are attempting
to start the unit. To get the engine started, you
must add the requiredamountof oiltothe engine
crankcase.
C.Use of the OILGARD system on applications that
are subject to shock, bumping or severe angles
of operation (inexcess of
15 degrees)should be
avoided. This isespecially true if an unexpected
shutdown would cause asafety hazardor serious
inconvenience for the operator. To disable the
OILGARD, removethe wire attached to the sen-
sor unit mounted on the engine crankcase. The
wire should be insulated with a connector or
tape.
LOW OIL LEVEL SHUTDOWN SYSTEM
1. BRIGGS & STRATTON Powered Generators - These
enginegenerator sets come equipped standard with
the Briggs
& Stratton OILGARD warning system.
A. This low oil warning system will automatically
stop the engine well before the oil level reaches
an operational danger point. This feature is de-
signed to prevent costly repairs and downtime.
