
Thismanualhasimportantsafety
information.Readthroughitcarefully
beforeoperatingthismachinetoprevent
personalinjuryormachinedamage.Learn
theoperation,limitationandthespecific
potentialhazardspeculiartothisband
saw.

Donotoperatethismachineunlessitis
completelyassembled.

Makesurethepowerswitchisoffbefore
plugginginpowercord.

Disconnectthepowercordbeforemaking
adjustment,maintenanceorblade
changes.

Keepallguardsandshieldsinplacebefore
installingorstartingupthemachine.

Wearproperapparelduringoperation
andwhenservicingthemachine.
Keepunauthorizedpersonnelaway.

Donotreachoverorstandonanypartof
themachine.

Neverholdthematerialbyhandfor
cutting.Alwaysusetheviseandmake
surethematerialisclampedsecurely
beforecutting.

Itisdangeroustooperatethemachine
whenthefloorisslippery.Keepthefloor
cleananddry.Checkforice,moisture,or
greasebeforeentering.

Donotusethemachinetocutexplosive
materialorhighpressurevesselsasitwill
generategreatamountofheatduringthe
sawingprocessandmayignitean
explosion.

Keeptheworkenvironmentsafe.Donot
usebandsawinadamporwetlocation.

Neveroperatewhileundertheinfluence
ofdrugs,alcoholormedication.

Allusersmustreaditbeforeperformingany
activityonthemachine,suchasreplacing
thesawbandordoingregularmaintenance.
Somepersonalprotectiveequipmentis
requiredforthesafeuseofthemachine,e.g.
protectiongoggles.
Keepbladeprotectioncoverandwheel
coversinplaceandinworkingorder.
Userecommendedaccessories.Improper
accessoriesmaybehazardous.
Keepyourworkareawellilluminatedat
minimum500lumen.
Keepyourworkareaclean.Clutteredand
slipperyfloorsinviteaccidents.
Removeadjustingkeys,wrenchesorany
loosepartsoritemsfromthemachine
beforeturningonpower.
Checkfordamagedparts.Beforecontinuing
usingthemachine,thedamagedpartshould
becheckedandreplaced.
Movingpartsshouldbekeptinproper
alignmentandconnectionwiththemachine.
Checkforbreakage,mountingandanyother
conditionsthatmayaffectitsoperation.Any
damagedpartorguardshouldbeproperly
repairedorreplaced.
Whenaworkpieceistoolongorheavy,
makesureitissupportedwitharollertable
(recommended).
Alwaysremembertoswitchoffthemachine
whentheworkiscompleted.
Useasharpsawbladeandkeepthemachine
initsbestandsafestperformanceby
followingaperiodicalmaintenanceschedule.
Donotforcethebandsawbeyondits
intendeduse.Itissafertooperatewiththe

5. Bladeguardcover(left&right)

Theprotectiondevicesshouldalwaysbemountedonthemachinewheneverthemachineis
running.
Donotremoveanyofthesesafeguarddevicesunderanycircumstancesexceptwhenservicing
themachine.Evenskilledservicetechniciansshouldstilltakecautionswhenperformingrepairs

SafetyRelatedSwitches
Toprotecttheoperator,thefollowingsafetyrelatedswitchesonthemachineareactuatedwhenthe
machineisinoperation.

WheelmotiondetectorThisisaproximitysensorusedtodetectthemotion
ofthedrivewheel.Oncethesawbladeisbrokenor
assoonasitstartsslipping,thesensorwilldetect
andstopthedrivewheelandthemachine.
PowerswitchLocatedonthecoverofelectricalcabinet,thepower
switchcontrolsthemainpowerofthemachine.Up
toyourcompany’sinternalrules,thispowerswitch
canbelockedwithapadlockoraluggagelockto
protecttheoperatorandthemachine.
EmergencystopbuttonLocatedonthecontrolpanel,thebuttonwhen
pressedwillstopthemachinecompletely.
ViseclampswitchThisswitchassuresfirmclampingoftheworkpiece.If
theworkpieceisnotclampedproperly,thesaw
bladeisnotallowedtorun.
Wheelcoverinterlockswitches
(CEmodelonly)
Locatedonthetwowheelhousings,theseswitches
areusedtoassurethatthemachinewillstop
wheneverthewheelcoversareopen.Thisdeviceis
toprotectusersfrombeingcutbytherunningsaw
blades.

Amongallthesesafetyswitches,someofthemareusedtoprotecttheusersandsomeofthemare
usedtopreventdamagetosawblades,theworkpieceandthemachineitself,etc.Wehavetaken
everyprecautiontopreventinjuryordamageandtoprovidesafeandeconomicaloperationofthe
machine.


EMERGENCYSTOP
Designedtobeeasilyaccessible,theemergencystopbuttonislocatedontheleftbottomcorneron
thecontrolpanelandismadeinredcolorandrubbermaterial.ForCEmodels,supplementary
emergencystopbuttonmaybeavailableatotherarea(s)ofthemachinedependingonmachinetype.
PleaserefertoIllustration:EmergencyStop.
Whenyoupressthebutton,themachinewillimmediatelycometoafullstoptoavoidinjuryor
damagewhenanaccidentoccurs.Thebuttonwillbelockedwhenyoupressit.Tounlockit,pullit
upward.
Youshouldpressitimmediatelywithoutanyhesitationwhenobserving:
Anemergencysituationthatwouldcauseanyinjuryordamage
Anabnormalsituationorproblemsuchasfire,smoke,abnormalnoiseandetc.

ThisbandsawmachineisdesignedbyCosen’sR&Dengineerstoprovideyouthefollowingfeatures
andadvantages:
Safety
Thismachineisdesignedtofullyprotecttheoperatorfromitsmovingpartsduringcutting
operation.
Themachineandeachcompomenthaspassedstricttesting(CouncilDirectiveonthe
approximationofthelawsoftheMemberStatesrelatingtoMachinery).
Themachinewillshutoffautomaticallywhenthesawbladeisbroken,protectingboththe
operatorandthemachine.
Convenience&High‐Performance
Themachineisdesignedinthewaythattheoperationandadjustmentcanbeeasily
performed.
Themachinewillstopautomaticallywhenoutofstock.
Dualvalvesystemisdesignedtoachieveoptimalcuttingperformancewiththesimple
settingoffeedrateandperspectivecuttingpressurefordifferentmaterial.
Durability
Theintendedlife‐spanofthemachineiscountedbasedonregulardailyoperation.Itis
calculatedwiththelifeexpectancyof10yearsundernormaloperatingconditionandexact
attentiontothemaintenanceschedule.
8hours×5days×52weeks×10years＝20,800hours
