41. GROUNDINGINSTRUCTIONS:Intheeventofamalfunctionorbreakdown,groundingprovidesa
pathofleastresistanceforelectriccurrenttoreducetheriskofelectricshock.Youlatheis
equippedwithanelectriccordhavinganequipmentgroundingconductorandagroundingplug.
Theplugmustbepluggedintoamatchingoutletthatisproperlyinstalledandgroundedin
accordancewithalllocalcodesandordinances.

Donotmodifytheplugprovided–ifitwillnotfittheoutlet,havetheproperoutletinstalledbya
qualifiedelectrician.Improperconnectionoftheequipment‐groundingconductorcanresultina
riskofelectricshock.Theconductorwithinsulationhavinganoutersurfacethatisgreenwithor
withoutyellowstripesistheequipment‐groundingconductor.Ifrepairorreplacementofthe
electriccordorplugisnecessary,donotconnecttheequipment‐groundingconductortoalive
terminal.Checkwithaqualifiedelectricianorservicepersonnelifthegroundinginstructionsare
notcompletelyunderstood,orifindoubtastowhetherthetoolisproperlygrounded.Useonly3‐
wireextensioncordsthathave3‐pronggroundingplugsand3‐polereceptaclesthatacceptthe
tool’splug.Repairorreplacedamagedorworncordimmediately.


Unpacking Yourlatheisshippedfullyassembled.Robustlathesareheavy.Gethelp.Usecarewhen
removingthelathefromthepallet.Usea2x4underthewaystoliftoneendofthelatheata

Location
Thebestlocationisonalevelconcretefloorclosetoapowersourceinanareawithgood
lighting.Provideclearanceonallsidesofthelathe.Othermachinesinyourshopshouldnot
interferewiththeoperationofthelathe.
Lighting Yourshopandtheworkareaaroundthelatheshouldhaveadequatelighting.Amovable
spotlightmaybehelpful.Alightstand‐offmountisincludedontopoftheheadstockforeasy
lightmounting.
Boltingto
Floor
Ifyoudonotplantomoveyourlathe,youmightconsiderboltingittothefloor.Firstmake
sureitislevelandsettledperotherinstructionsinthismanualandthenuseanygoodquality
anchor.Ifyouareboltingtoconcrete,makesuretherearenoexpansionjointsorcracks
betweenthelegs.Ifboltingtoawoodenfloor,itisbesttogetoverthejoists.Settlethelathe
bothbeforeandafterbolting.
Ventilation Yourshopshouldbeadequatelyventilated.Theamountofventilationneededvariesbased
onthesizeoftheshopandtheamountofworkdone.Theuseofdustcollectorsandfilters
willminimizeriskstoyourhealth.Somewoodsaretoxicorwillcauseallergicreactions.
Electrical MostRobustlathesarewiredfor220V.An
isolated220VAC,20ampcircuitisrequired.
Wiringandoutletsshouldadheretolocal
electricalcodes.

Latheswiredfor110(1.5HPonly)shouldbe

 Donotleavethelatheunattendedwithpoweron.Itisrecommendedthatyouunplugthelathe
whenyoutakeanextendedbreakorarefinishedwithyourturningsession.Thisalsogivesyoumaximum
protectionagainstpowersurgesandlightningstrikes.

Yourlatheisequippedwitha3phaseACindustrialgrademotor.Themotorisfancooledandthereisan

VariableFrequencyDriveor“Inverter”
Yourlatheisequippedwithanindustrialgradevariablefrequency
drive(VFD),alsoknownasan“inverter”.Thedrivetakesnormal
householdcurrentandconvertsittoindustrial3phasepower.When
youchangethespindlespeeddialonthependantcontroller,the
drivechangesthefrequencysenttothemotorwhichchangesthe
motorspeed.ThedrivealsocalculatesthespindleRPMandshows
theresultsonitsdisplay.
Thedriveisfactorysetwithparametersthatmostturnerswilllike.
Thedrivemanual,includedwiththelathe,showshowtochangethe

runningproperly,ifatall.Othersettings,suchasrampupandramp
downspeedscanbesettoyourliking.

Itisstronglyrecommendednottochangeanyparameters
untilyouareveryfamiliarwithyourlathe.Ifyouareunhappywith

AdjustingDriveBeltTension 
Thebeltdoesnotneedtobeovertight.Havingthebeltabit
looseisactuallybeneficialsometimes,likewhenyouarecoring,
asthebeltwillslipinsteadofstallingthemotorwhenyougeta
catchoroverloadthesystem.
Toadjustthebelttension,removethecoverplateandloosen
boththeMotorPivotandBeltTensionNuts.Youdon’tneed
anymoretensiononthebeltthanyoucanapplybyhand.Do
notusealeveronthemotororpulleytoincreasetension.
Doingsojustputsneedlessstressonthemotorbearingsand
willleadtotheirprematurefailure.


Thevacuumadaptersimplyslipsintothespindleonthe

SomelubricantontheO‐ringsmakesthisprocesseasierand
