Push theworkpiece steadily forward; completethe cut as a single movement. Do notdraw the workpiece back, as thiscould cause the sawblade to run off itswheels.Support long and wide workpieceswith helping roller stands.Operating hints:Work only with a sharp and flawlesssawblade.Near the cutting area use a push stickto feed.Use a feeding template to safely guidesmall and narrow workpieces.Use a suitable wedge to prevent roundtimber from turning under thepressure of the cut.Bring the upper blade guide to adistance of approx 5mm to theworkpiece.For the authorized use of themachine observe the appendix A“safe operation“(on the last pages of this operatingmanual)A.1: Performing high cutsA.2.: Performing diagonal cutsA.3.: Tenon cuttingA.4.: Cutting of wedgesA.5.: Curved cutsA.6.: Arc cutsA.7.: Cutting with templateA.8.: Circular cuttingA8.1 Set up without workpieceA8.2 Placing the workpieceA8.3 Machining7.
