2‐Safety

1. Duringanyworkonnon‐horizontalcomponents,themachinemustalwaysbesecuredwiththe
suppliedsafetychain.

2. Themagneticdrillingmachinemayonlybeusedonaflatandcleanfoundation.

3. Ifthemachineortheleadshowsignsofdamage,themagneticdrillingmachinemustbeswitched
offimmediately.

4. Wearingsafetyglasses,hearingprotectionandprotectiveclothingisnecessary.

5. Donotwearanylooseclothingorjewellerythatmaygetentangledinthemovingpartsofthe
magneticdrillingmachine.

6. UseonlyaccessoriesorpartsthatarerecommendedbyRotec.

7. Duringdrilloperations,theholecuttermustbecooledandlubricatedwithgoodqualitycuttingor
lubricationoil.

8. Themotormustbeswitchedoffwhentighteningthemachinewiththesafetychain.

9. Whenchangingaholecutter,themagneticdrillingmachinemustbedisconnectedfrompower

drillingbuttheywillalsolengthenthelifespanofyourtools.Oneoftheadvantagesof
theuseofholecuttersisthatcoolingandlubricationagentscanbesuppliedfromthe

6‐TheMagneticDrillingMachine

TheMagneticbase
Materialofminimum10mmthicknessisrequiredforthemagnettoworkthebest.

Theattachmentforcegeneratedbythemagnetdependsonvariousfactors.
‐Thicknessofthematerialthemagnetisplacedon
‐Paintorcoatingofthematerialthemagnetisplacedon.
‐Metalchips,oilorotherdirtunderthemagnet.

IftheLEDindicator(seechapter4‐3‐2)lightsupGREEN,themagnetisgeneratingsufficientattachment
force.IftheLEDindicatorlightsupRED,themagnetmaynotgeneratingsufficientattachmentforce.

Wewouldliketopointoutthatthisisonlyanindicationandnotacertainlythatthemagnetwillnot
releasefromthematerial.Rotecacceptsnoliabilityensuringfromthemagnetindicatornotfunctioning
orfunctioningpoorly.

Makesurethatthemagnetattachestightlytotheworkpiecebeforeturningonthemotorunitofthe
magneticdrillingmachine.Rotecmagnetshave2coils;makesurethatbothcoilsareincontactwiththe
material.Donotconnectanyothermachinestotheelectricaloutletthemagneticdrillingmachineis
pluggedinto,asitmayresultinthelossofmagneticforce.Alwaysusethesafetychainincluded.Drilling

Drilling
Nowthatyouhavereadtheexplanatoryinformationandsafetyrecommendationsabove,youarereadyto
actuallystartdrilling.Followthese10stepsforbestdrillingresult:

1Usethetipofthepilotpintodeterminethecenteroftheholetobedrilled.

2Turnthemagnetonandverifythatthedrillisintherightpositionandthatthemachineis  
pushedtightagainsttheworkpiece.`

3Ifyourmachineisequippedwithaautocoolantsystem,putopenthevalvetoreleasetheoil.
Ifyourmachinedoesnothaveaautocoolantsystem,filltheholesofthespindlewithoil.

4Turnthemotoronatthehighestsettingandallowittorunatfullspeed.

5Turnthearmstostartdrilling.Applyonlyaslightpressurewhentheholecuttertouchthe  
metal.Donotpushtheholecutterwithforceintothemetal.

6Applyaregularpressurewhiledrilling.Thedrillingperformancedoesnotimprovebyputting 
morepressureonthetool.Toomuchpressurewilloverloadthemotorandyourholecutter  
willbewornsooner.Letthecutterdothejobandgiveittimetocutthemetal!!!

7Adjusttheoilsupplywhennecessary,ifyourdrilldoesnothaveaautocoolantsystem,stop  
drillingregularly,refilltheholesofthespindleandcontinuedrilling.

8Applylesspressurewhenthedrillcutsthroughthematerial.

9Turnthearmstoputthemotorinhighestpositionandturnoffthemotorunit.

10Removetheburr,metalchipsandcleanthecutterandsurfacewithoutgettinginjuries.   
Caution:Themetalpiecedrilledoutcanbesharpandveryhot!!




!!!IMPORTANT!!!
Whenusingyourmagneticdrillingmachinenon‐horizontalorupside‐downbeaware
thatnooil,drillingcompoundormetalchipscanfallintothemotorunit.
Rotecacceptsnoresponsibilityfordamagedonetoyourmachine
bysuchactionundercoverageofthewarranty.




5‐Maintenance

Justaseverymagneticdrillingmachinewithmovingparts,yourRotecmagneticdrillingmachinealsoneeds
regularmaintenanceservice.Afewrecommendationsfollow:

‐ Cleanalldirt,dust,metalchipsandburrsofyourmagneticdrillingmachine

‐ Regularlycheckthecarbonbrushesforwear

‐ Replaceanydefectivepartsimmediately.Thispreventsproperlyfunctionpartsfrombeingdamaged.

‐ Adjustyourguideregularlyandmakesureitiscleanandgreased.Thispreventsanymovementfrom
beingcreatedandthespindle,triangularguide(steady)andguidepartsfromexcessivewearor
damage.Theguidecanbeadjustedbylooseningthesettingnut(#7onsparepartdrawing)with
includedwrench8,tighteningthesettingscrews(#5onsparepartdrawing)withincludedAllenkey
2.5andtighteningthesettingnut(#7)againwithincludedwrench8.Theadjustmentisdonewell
whenthemotorunitcanbeturnedtoeverypossiblepositionwithoutfallingdownbyitsownweight.

‐ Checkthegreaseinthegearboxregularlyandreplaceitifnecessary.Werecommendyoutostore
yourmachineonitssideregularlysothatthegearboxgreasecanrunbacktowherethegearsare.
Thisisveryimportantwhenyouhaveusedyourmachinenon‐horizontalorupsidedown.
Repair,modificationandinspectionofRotecMagneticdrillingmachinesmustbedonebya Rotec
authorizeddealer.ThepartslistwillbehelpfulifpresentedwiththemachinetotheRotecdealerfor
servicewhenrequestingrepairorothermaintenance.
Rotecmachinesareconstantlybeingimprovedandmodifiedtoincorporatethelatest technological
advancements.Accordingly,someparts(iepartnumbersand/ordesign)maybe changedwithoutprior
notice.Also,duetoRotec'scontinuingprogramofresearchand development,thespecificationsof
machinesaresubjecttochangewithoutpriornotice.
