IF doors and windows are open! ONLY use
outdoors and far from open windows, doors,
vents, and in an area that will not accumulate
deadly exhaust.
_t The engine exhaust fumes contain carbon
monoxide, which you cannot see or smell.
This poisonous gas, if breathed in sufficient
concentrations, can cause unconsciousness or
even death.
,_Adequate, unobstructed flow of cooling and
ventilating air is critical to correct generator
operation. Do not alter the installation or permit
even partial blockage of ventilation provisions,
as this can seriously affect safe operation
of the generator. The generator MUST be
operated outdoors.
_t This exhaust system must be properly
maintained. Do nothing that might render the
exhaust system unsafe or in noncompliance
with any local codes and/or standards.
_t Always use a battery operated carbon
monoxide alarm indoors, installed according to
the manufacturer's instructions.
Using a generator indoors CAN KiLL YOU iN MINUTES.

2.4.1 GROUNO/NGTHEGENERATORWHENUSEDASA
PORTABLE
This generator has an equipment ground that connects the
generatorframe componentsto the ground terminals on the AC
output receptacles (see NEC 250.34 (A) for explanation).This
allows the generatorto be used as a portablewithout grounding
the frame ofthe generatorasspecifiedin NEC250.34.
SpecialRequirements
There may be Federalor State OccupationalSafety and Health
Administration(OSHA)regulations,localcodes,or ordinancesthat
applyto the intendeduse ofthe generator.
Pleaseconsult a qualified electrician,electrical inspector, or the
local agencyhavingjurisdiction:
* In some areas, generators are requiredto be registeredwith
local utilitycompanies.
* If the generatoris used at a construction site, there may be
additionalregulationswhich must be observed.
2.4.2 CONNECT/NGTHEGENERATORTOABU/LD/NG'$
ELECTRICALSYSTEM
Connectionsfor standby power to a building's electricalsystem
must be made by a qualifiedelectricianand in strict compliance
with all national and local electrical codes and laws. The
connectionmust isolatethegeneratorpowerfrom utility poweror
otheralternativepowersources.
NOTE:
Becausethe generator equipmentground is bondedto the AC
neutralwiresin thegenerator,eithera 3-poletransferswitchor
a 2 poletransferswitchwith a switchingneutralkit is required
to connectthisgenerator to a buildingload.In this application
the generator becomesa separatelyderived system(see NEC
250.20 (D)), and must be grounded in accordance with the
nationalor localelectricalcoderequirements.
,_The National Electrical Code requires that the
frame and external electrically conductive parts
of this generator be properly connected to an
approved earth ground,
Local electrical codes may also require proper grounding of
the unit (Figure8). Forthat purpose, connectinga No. 10 AWG
(AmericanWireGauge)strandedcopperwireto the groundinglug
and to an earth-drivencopperor brass grounding rod (electrode)
provides adequateprotection against electrical shock. However,
local codes may vary widely.Consultwith a localelectricianfor
grounding requirementsin thearea.
Proper groundingof the generatorwill help preventelectrical
shockin theeventof a groundfault conditioninthe generatoror in
connectedelectricaldevices.Propergroundingalsohelpsdissipate
static electricity,which often buildsup in ungroundeddevices.

2.5 DON'TOVERLOADTHEGENERATOR
Overloadinga generatorin excess of its ratedwattage capacity
can result in damageto the generatorandto connectedelectrical
devices.Observethefollowing to preventoverloadingthe unit:
* Addupthetotal wattageofall electricaldevicesto be connected
at one time. This total should NOT be greater than the
generator'swattagecapacity.
* The ratedwattageof lights can betaken from light bulbs. The
ratedwattageof tools, appliancesand motors can usually be
foundon a datalabelor decalaffixedto the device.
* If the appliance,tool or motor does not give wattage,multiply
voltstimes ampereratingto determinewatts (voltsx amps =
watts).
* Some electric motors, such as induction types, require about
threetimes morewatts of powerfor startingthan for running.
This surge of power lasts only a few seconds when starting
such motors.Makesureto allowfor high startingwattagewhen
selectingelectricaldevicesto connectto the generator:
1. Figurethe watts neededto start the largestmotor.
2. Add to that figure the running watts of alt other connected
loads.
TheWattageReferenceGuideis providedto assist in determining
how many itemsthe generatorcan operateatonetime.
NOTE:
All figures are approximate. See data label en appliancefor
wattage requirements.

2.12CHARGINGTHEBATTERY(ELECTRICSTART
UNITSONLY)
Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion.
Such an explosion can shatter the battery and
cause blindness or other serious injury.
Do not permit smoking, open flame, sparks or
any other source of heat around a battery. Wear
protective goggles, rubber apron and rubber
gloves when working around a battery. Battery
electrolyte fluid is an extremely corrosive
sulfuric acid solution that can cause severe
burns. If spill occurs flush area with clear water
immediately.
NOTE:
Thebattery shippedwith the generator has been fully charged.
A battery may 10sesome of its chargewhen not in use for
pr0i0ngedperiodsof time. if the battery is unable to crankthe
engine, plugin the 12V chargerincludedin the accessorybox.
RUNNING THE GENERATOR DOES NOT CHARGE THE BATTERY.
Usebatterychargerplugto keepthe batterychargedandreadyfor

3.7 GENERAL
Thegeneratorshould be started at least once every 30 days and
be allowedto run at least 30 minutes. If this cannot be done and
the unit must be stored for morethan 30 days, use thefollowing
informationas a guideto prepareitfor storage.
NEVER store engine with fuel in tank indoors
or in enclosed, poorly ventilated areas where
fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer
or other gas appliance.
,_Ailow unit to cool entirely before storage.
3.B LONGTERMSTORAGE
It is importantto preventgum depositsfrom forming in essential
fuel systemparts such asthe carburetor,fuel hoseor tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol,ethanolor methanol)can attract moisture,which
leadsto separationandformation of acids during storage.Acidic
gascan damagethefuel systemof an enginewhile in storage.
To avoid engine problems, the fuel system should be emptied
beforestorageof 30 daysor longer,asfollows:
1. Addaqualitygasolinestabilizertothefuelperthemanufacturer's
specifications,and run the unitfor 10-15 minutes.
2. After engine cools down, remove all gasolinefrom the fuel
tank. Use a commerciallyavailable, non-conductivevacuum
siphon.
Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke.
3. Start and run engineuntilenginestopsfrom lackof fuel.
4. After engine cools down, drain oil from engine. Refill with
recommendedgrade.
5. Remove spark plug and pour about 1/2 ounce (15 mt) of
engineoil intothecylinder.Coverspark plugholewith rag.Pull
the recoil starter a coupletimes to lubricatethe piston rings
and cylinder bore.A fogging agent can also be used in the
placeof oil.
ACAUTION!
,_Avoid spray from spark plug hole when
cranking engine.
6. Installandtightenspark plug.Donot connectsparkplugwire.
7. Cleanthe generatorouter surfaces. Check that cooling air
slots andopeningson generatorareopenand unobstructed.
8. Storethe unit in a clean, dry place.
3.9 OTHERSTORAGETiPS
• Do notstoregasolinefrom oneseasonto another.
• Replacethe gasolinecan if it starts to rust. Rustand/ordirt in
the gasolinewill cause problems with the carburetor and fuel
system.
• If possible,storethe unit indoorsandcoverit to giveprotection
from dust anddirt. BESURETOEMPTYTIdEFUELTANK.
• If it is not practicalto empty the fuel tank and the unit is to
be stored for some time, use a commercially availablefuel
stabilizer added to the gasoline to increase the life of the
gasoline.Runthe unitfor 10-15 minutes,turn off thefuelvalve
and allowto run untilenginestopsfrom lack of fuel.
• Coverthe unit with a suitable protective cover that does not
