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.

GroundingtheGeneratorinaBuildingStandbyApplicati0n

Generator exhaust contains carbon monoxide. This is

a poison you cannot see or smell.

NEVER use inside a home

or garage, EVENiF doors

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

use. Batterychargingshouldbe done in a dry location.

1. Plugchargerinto "Battery ChargerInput"jack, locatedon the

control panel.Plug wall receptacleend of the batterycharger

into a 120 VoltACwalt outlet.

2. Unplugbatterychargerfrom walt outletand control paneljack

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

retainmoisture.
