Makesureanyuseoffireisprohibitedintheshopandinstallafireextinguisherorotherfirecontrol
devicenearthemachinewhencuttingtitanium,magnesium,oranyothermaterialthatproduces
flammablechips.Neverleavethemachineunattendedwhencuttingflammablematerials.
Neveradjustthewirebrushorremovechipswhilethesawbladeisstillrunning.Itisextremely
dangerousifhandsorclothingarecaughtbytherunningblade.
Nevertouchtherunningsawbladewithglovesornot.Itisdangerousifyourhands,clothingor
glovesarecaughtbytherunningblade.
Stopthesawbladebeforeyoucleanthemachine.Itisdangerousifhandsorclothingarecaughtby
therunningblade.
Neverstartthesawbladeunlesstheworkpiecehasbeenclampedfirmly.Iftheworkpieceisnot
securelyclamped,itwillbeforcedoutoftheviseduringcutting.
Takepreventivemeasureswhencuttingthinorshortpiecesfromtheworktokeepthemfrom
falling.Itisdangerousifthecutpiecesfall.
Userollertablesatthefrontandrearsidesofthemachinewhencuttinglongwork.Itisdangerousif
theworkpiecefallsoffthemachine.
