Followtheserulesbelowtoensuregeneralsafety:

• Observeagoodhousekeepingintheareawherethemachinesareputduring

andafterthemaintenance.

• Whenliftinganyheavyobject:

1. Makesurethatyoucanstandsafelywithoutslipping.

2. Distributetheweightoftheobjectequallybetweenyourfeet.

3. Useaslowliftingforce.Nevermovesuddenlyortwistwhenyouattempt

toliftit.

4. Liftitbystandingorpushingupwithyourlegmuscles;thisactioncould

avoidthestrainfromthemusclesinyourback.Donotattempttoliftany

objectthatweighsmorethan 16kg(35lb)orthatyouthinkistooheavyfor

you.

• Donotperformanyactionthatcauseshazardstothecustomer,orthatmakes

themachineunsafe.

• Beforeyoustartthemachine,makesurethatotherservicerepresentatives

andthecustomerarenotinahazardousposition.

• Placeremovedcoversandotherpartsinasafeplace,keepingthemaway

fromallpersonnel,whileyouareservicingthemachine.

• Keepyourtoolcaseawayfromwalkareassothatotherpeoplewillnottripit

over.

• Donotwearlooseclothingthatcanbetrappedinthemovingpartsofthe

machine.Makesurethatyoursleevesarefastenedorrolledupaboveyour

elbows.Ifyourhairislong,fastenit.

• Inserttheendsofyournecktieorscarfinsideclothingorfastenitwiththe

nonconductiveclip,about8centimeters(3inches)fromtheend.

• Donotwearjewelry,chains,metal‐frameeyeglasses,ormetalfastenersfor

yourclothing.

Attention:Metalobjectsaregoodelectricalconductors.

• Wearsafetyglasseswhenyouarehammering,drilling,soldering,cutting

wire,attachingsprings,usingsolvents,orworkinginanyotherconditions

thatmaybehazardoustoyoureyes.

• Afterservice,reinstallallsafetyshields,guards,labels,andgroundwires.

Replaceanysafetydevicethatiswornordefective.

• Reinstallallcoverscorrectlybeforereturningthemachinetothecustomer.

General safety

Safetyinformation

Observethefollowingruleswhenworkingonelectricalequipments.

• Findtheroomemergencypower‐off(EPO)switch,disconnectingtheswitch

orelectricaloutlet.Ifanelectricalaccidentoccurs,youcanthenoperatethe

switchorunplugthepowercordquickly.

• Donotworkaloneunderhazardousconditionsorneartheequipmentthat

hashazardousvoltages.

• Disconnectallpowerbefore:

– Performingamechanicalinspection

– Workingnearpowersupplies

– Removingorinstallingmainunits

• Beforeyoustarttoworkonthemachine,unplugthepowercord.Ifyou

cannotunplugit,askthecustomertopower‐offthewallboxthatsupplies

powertothemachine,andtolockthewallboxintheoffposition.

• Ifyouneedtoworkonamachinethathasexposedelectricalcircuits,observe

thefollowingprecautions:

– Ensurethatanotherperson,familiarwiththepower‐offcontrols,isnear

you.

Attention:Anotherpersonmustbetheretoswitchoffthepower,if

necessary.

– Useonlyonehandwhenworkingwithpowered‐onelectricalequipment;

keeptheotherhandinyourpocketorbehindyourback.

Attention:Anelectricalshockcanoccuronlywhenthereisacomplete

circuit.Byobservingtheaboverule,youmaypreventacurrentfrom

passingthroughyourbody.

– Whenusingtesters,setthecontrolscorrectlyandusetheapprovedprobe

leadsandaccessoriesforthattester.

– Standonsuitablerubbermats(obtainedlocally,ifnecessary)toinsulate

youfromgroundssuchasmetalfloorstripsandmachineframes.

Observethespecialsafetyprecautionswhenyouworkwithveryhighvoltages;

instructionsfortheseprecautionsareinthesafetysectionsofmaintenance

information.Beextremelycarefulwhenyoumeasurethehighvoltages.

• Regularlyinspectandmaintainyourelectricalhandtoolsforsafeoperational

condition.

• Donotusewornorbrokentoolsandtesters.

• Neverassumethatpowerhasbeendisconnectedfromacircuit.First,checkit

tomakesurethatithasbeenpoweredoff.

Important:

Useonlyapprovedtoolsandtestequipments.Somehandtoolshave

handlescoveredwithasoftmaterialthatdoesnotinsulateyouwhen

workingwithliveelectricalcurrents.

Manycustomershaverubberfloormatsneartheirmachinesthatcontain

smallconductivefiberstodecreaseelectrostaticdischarges.Donotusesuch

kindofmattoprotectyourselffromelectricalshock.

• Alwayslookcarefullyforpossiblehazardsinyourworkarea.Examplesof

thesehazardsaremoistfloors,nongroundedpowerextensioncables,power

surges,andmissingsafetygrounds.

• Donottouchliveelectricalcircuitswiththereflectivesurfaceofaplastic

dentalmirror.Thesurfaceisconductive;suchtouchingcancause

personal

injuryandmachinedamage.

• Donotservicethefollowingpartswiththepoweronwhentheyareremoved

fromtheirnormaloperatingplacesinamachine:

– Powersupplyunits

– Pumps

– Blowersandfans

– Motorgenerators

andsimilarunits.(Thispracticeensurescorrectgroundingoftheunits.)

• Ifanelectricalaccidentoccurs:

– Caution:donotbecomeavictimyourself.

– Switchoffthepower.

– Sendthevictimtogetmedicalaid.

Safetyinformation

Thepurposeofthisinspectionguideistoassistyouinidentifyingpotential

unsafeconditions.Aseachmachinewasdesignedandbuilt,requiredsafety

itemswereinstalledtoprotectusersandservicepersonnelfrominjury.This

guideaddressesonlythoseitems.Youshouldusegoodjudgmenttoidentify

potentialsafetyhazardsaccordingtotheattachmentofnon‐Lenovofeaturesor

optionsnotcoveredbythisinspectionguide.

Ifanyunsafeconditionsarepresent,youmustdeterminehowseriousthe

apparenthazardcouldbeandwhetheryoucancontinuewithoutfirstcorrecting

theproblem.

Considertheseconditionsandthesafetyhazardstheypresent:

• Electricalhazards,especiallyprimarypower(primaryvoltageontheframe

cancauseseriousorfatalelectricalshock)

• Explosivehazards,suchasadamagedCRTfaceorabulgingcapacitor

• Mechanicalhazards,suchaslooseormissinghardware

Todeterminewhetherthereareanypotentialunsafeconditions,usethe

followingchecklistatthebeginningofeveryservicetask.Beginthecheckswith

thepoweroff,andthepowercorddisconnected.

Checklist:

1. Checkexteriorcoversfordamage(loose,broken,orsharpedges).

2. Turnoffthecomputer.Disconnectthepowercord.

3. Checkthepowercordfor:

a. Athird‐wiregroundconnectoringoodcondition.Useametertomeasure

third‐wiregroundcontinuityfor0.1ohmorlessbetweentheexternal

groundpinandtheframeground.

b. Thepowercordshouldbethetypespecifiedinthepartslist.

c. Insulationmustnotbefrayedorworn.

4. Checkforcrackedorbulgingbatteries.

5. Removethecover.

6. Checkforanyobviousnon‐Lenovoalterations.Usegoodjudgmentastothe

safetyofanynon‐Lenovoalterations.

7. Checkinsidetheunitforanyobviousunsafeconditions,suchasmetalfilings,

contamination,waterorotherliquids,orsignsoffireorsmokedamage.

8. Checkforworn,frayed,orpinchedcables.

9. Checkthatthepower‐supplycoverfasteners(screwsorrivets)havenotbeen

removedortamperedwith.

Anycomputerpartcontainingtransistorsorintegratedcircuits(ICs)shouldbe

consideredsensitivetoelectrostaticdischarge(ESD).ESDdamagecanoccur

whenthereisadifferenceinchargebetweenobjects.ProtectagainstESDdamage

byequalizingthechargesothatthemachine,thepart,theworkmat,andthe

personhandlingthepartareallatthesamecharge.

WhenhandlingESD‐sensitiveparts:

• Keepthepartsinprotectivepackagesuntiltheyareinsertedintotheproduct.

• Avoidcontactwithotherpeople.

• Wearagroundedwriststrapagainstyourskintoeliminatestaticonyour

• Usetheblacksideofagroundedworkmattoprovideastatic‐freework

surface.ThematisespeciallyusefulwhenhandlingESD‐sensitivedevices.

• Selectagroundingsystem,suchasthoselistedbelow,toprovideprotection

thatmeetsthespecificservicerequirement.

– AttachtheESDgroundcliptoanyframeground,groundbraid,orgreen‐

wireground.

– Whenworkingonadouble‐insulatedorbattery‐operatedsystem,usean

ESDcommongroundorreferencepoint.Youcanusecoaxorconnector‐

outsideshellsonthesesystems.

– Usetheroundgroundprongoftheacplugonac‐operatedcomputers.
