maybebringssome dangers. Therefore,areincludedinthisinstruction
manual safetyrequirements.
·Readthismanualcarefullyandcompletelybefore operating the
splicer.
·Adhere toall safety instructionsand warningscontainedinthis
instruction manual.
·Retain thismanualfor future reference.
WARNING
1．Neveroperate thesplicerin an environmentwhereflammable liquids
orvapors exist.Riskof dangerousfireor explosionmayresult from
the electrical arc insuch an environment.
2．DOnot use the splicernear any hot equipment or in anyplaceof
high temperature.Possibleequipmentfailureor firemayresult.
3．Do nottouch thesplicer,AC powercord andAC plug if your hand
iswet. Possible electric shockmay occur.
4．Do not operate the splicer if watercondensationispresent on
surfaceofsplicer. Possibleelectricshockor equipment failure
mayresult.
5．Thesplicerisprecision adjustedandaligned.Donoe allow the unit
toreceiveastrongshockorimpact.Possibleequipmentfailure may
result. Usecarryingcase totransport andstorethe splicer.The
carryingcaseprotects the splicerfromdamage,moisture,vibration
and shock during storageand transportation.
6．Donotplace the splicer inan unstableor unbalanced position.The
splicer mayshift andlosebalance,causing theunittofall.Possible
personal injuryor equipment damage may result.
7．Keep the splicer freefromsand,dust,lubricantsandother
contaminants.Thepresenceofsuch substancesmay degrade the
splicingperformanceandcause equijpmentfailure or damage.
8．Donotuseanychemicalother thanalcohol tocleantheobjective
lens,V-groove,mirror,LCDmonitor,etc.,ofthesplicer.Otherwise,blur
ring,discoloration,damage or deteriorationmay result.
9．The splicer requiresno lubricatimn.Oilor grease maydegrade the
splicingperformanceanddamagethe splicer.
10．Do notuse compressed gasorcannedair tocleanthesplicer.They
maycontain flammablematerialsthat may igniteduringthe
electrical discharge.
11．Do notstore thesplicerinanyareawhere temperatureandhumidity
are extremely high. Possible equipment failure mayresult.
12．Beforeusingtheshoulderbeltof carryingcase,inspectthebelt
and hook forexcessivewearordamage.Carryingthe casewithadamaged
beltmay causeitto fall andmayresult inpersonalinjuryor
equijpment damage.
13．Do not touchthe electrodeswhenthe splicer is on and power is
supplied totheunit,theelectrodesgenerate highvoltageandhigh
temperaturesthat may causeasevereshockor burn. Turnthesplicer

off,and disconnect theAC powercord,orremove thebatterypackwhen
replacingthe electrodes.(Note:Opening thewindprotector stopsarc
discharge.)
14．Donotdisassemble ormodifythe splicer,ACadapter,batterypack,or
DCadapter.In particular,donorremove orbypass anyelectricalor
mechanicalsafetydevice(e.g.,fuseorsafety switch)incorporated
inthisequipment.Modificationcould causedamagethat may result
inpersonal injury,deathor electricshockorfire.
15．Useonlythe 85-264VAC,47-63Hz/12VDC,14Ah with WY-725.
.Theproper supply voltage source is85-264VAC,47-63Hz,Check theAC Power
sourcebeforeuse.Usingan improperAC powersourcemay causefuming,
electric shockorequipment damage andmay result in personal injury, death
orfire.
16.Use the suppliedACpower cord.Donotplace heavyobjects onthe
ACpower cord.Donotpull,heatup ormodifytheAC powercord. Use
ofanimproper cordor adamaged cordmaycausefuming,electricshock
orequipment damageand may resultinpersonal injury, deathorfire.
17.ConnecttheACpowercord properlytothesplicerandwallsocket.
When inserting theAC plug, make surethereisnodustordirt on
theterminals.Incomplete engagementmay causefuming, electric
shockor equipment damage and may result inpersonal Ijury,death
orfire.
18.The WY-725usesathree-prong(core) ACcordthat containsanearthed
groundsafetymechanism.Thesplicer MUST beGrounded/Earthed. Use
only the supplied three-prong(core)ACpowercord. NEVER usea
two-prong(core) power cord, extension cableorplug.
19.Use only theapproved batterypack with the WY-725. Only the
WY-725-01 batterypackcan be usedastheapprovedbatterypack.
20.Use the specifiedchargercord(WY-725-09) torecharge the battery
pack (WY-725-01).Usingother battery chargersandchargercords may
causefuming orequipmentdamageand resultin personalinjury,death
orfire.
21.The splicerinletis used to disconnect thepowercordintheevent
ofafault. Besure topositionthesplicer sothatthe powercord
can be disconnected easily and quickly.
22.Disconnect theAC or DCpowercord fromthesplicer inletorthe
wall socket(outlet)immediatelyif the splicerortheexternal
battery emitsfumesor bad smell, or becomes noisyor hot.Leaving
theabnormalcondition unattendedwillcauseequipment
failure,electricshockorfireand mayresultinpersonal
injury,death orfire.
23. DisconnecttheAC orDC powercord fromthesplicerinletorthe
wall socket(outlet) ifthe splicer becomesdamaged(e.g., by
dropping).Leaving thesplicerin adamaged statemay cause equipment
failure,electricshockorfireand mayresultinpersonal
injury,death orfire.
24．DisconnecttheAC or DCpowercordfrom the splicerinlet orthe
wall socket(outlet)immediately if liquid(e.g.,water)or foreign
matter (e.g.,screw) enters the splicer. Leaving the splicer in a
damaged statemaycause equipmentfailure,electric shockor fire and
may result in personal injury,death or fire.
25.Cautionshould betakenwhenremoving the fiberprotectionsleeve
fromthetube heaterafterthe heatshrink cycleiscompleted.The
Page3 Page4

tube heater andfiberprotection sleeve arehot and should
not be touched.Possibleburn may result.
26．Replace the electrodes properly.
·Useonly specified electrodes.
·Setthe newelectrodes in the correct position.
·Replace theelectrodes as apair.
Disregard ofthe aboveinstructions maycauseabnormal arcdischargeand
result inequipmentdamageordegradation in splicing performance.
27．The equipmentmust berepaired or adjustedbyaqualified technician
orengineer. Incorrect repairsmay causefire or electric shock.
Shouldany problemarise,pleasecontactyour nearestsalesagency.

5．MaintenanceofSplicing Quality
5．1Cleaning and CheckingbeforeSplicing
Critical cleaning pointsand maintenance checks aredescribed below.
5.1.1 Cleaning V-grooves
If contaminantsin theV-grooves, correctclamping maynot occur,
resultingin highersplice loss.TheV-grooves shouldbe frequently
inspected andperiodically cleaned during normal operation.
（l）Openthe wind protectorand fiberclamps.
（2）Cleanthe bottomoftheV-groove withanalcohol-impregnated
thin cottonswab asshown inFig.5－ l. Remove excessalcohol
from theV-groove with aclean dry swab.
