GENERAL CUTTING Fig. T-1 CUTTING CURVES When cutting curves, carefully turn the workpiece so the blade follows without twisting, If the curve is so sharp that you repeatedly back up and cut new kerf, use a narrower blade, or a blade with more set (teeth further apart).
Common causes of blade breakage: 䢇 Poor guide alignment and adjustment. 䢇 Forcing or twisting a wide blade around a short radius. 䢇 Feeding too fast. 䢇 Dull teeth or not enough set. 䢇 Too much blade tension. CHANGING SPEED SETTING (Fig. X) WARNING For longest wear and best cutting results, use the correct blade thickness width, and temper for the type of material you will cut. When sawing small curves and delicate work, use narrow blades.
