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.
•Fanlouversonthemachinehelptopreventtheoverheatingofinternal
components.Donotobstructfanlouversorcoverthemwithlabelsor
stickers.

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.
Electrical safety
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.

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
body.
•Preventthepartfromtouchingyourclothing.Mostclothingisinsulativeand
retainsachargeevenwhenyouarewearingawriststrap.
•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‐
