17. 8 Evaluating cutting efficiency Is the blade cutting efficiently The best way to tell is by observing the chips formed by the blade as it cuts If the chip formation is powdery then the feed is much too light or the blade is too dull If the chips formed are curled but straw or blue colored then the feed rate is too high Refer to Figure 12 for If the chips formed are curled but not colored then the blade is sharp enough and cutting at an efficient rate 9 9 Cutting procedure 1 Never start a cut with the blade resting on the work piece 2 Be certain you knock off the sharp corners of any work piece material which might damage the blade See Figure 4 3 Have the motor ON and running at full speed before lowering the blade into the cut 4 Use the hydraulic control valve to feed the blade into the work piece 5 If you use a cutting fluid turn the valve on before beginning the cut 9 10 Using the hydraulic feed control Refer to Figure 15 The hydraulic feed control cylinder is a single action hydraulic cylinder This allows you to lift the arm at any time easily but controls the downward movement of the arm using a valve on the top of the cylinder Hydraulic ee control cylinder Figure 15 Hydraulic feed control When the control valve is turned fully clockwise the cylinder is locked and the saw arm will not move downward You can lock the arm using the valve at any position in its tra
