187. Cutting aluminum extrusion12345001844When securing aluminum extrusions, use spacerblocks or pieces of scrap as shown in the figure toprevent deformation of the aluminum. Use a cuttinglubricant when cutting the aluminum extrusion toprevent build-up of the aluminum material on theblade.CAUTION:• Never attempt to cut thick or round aluminumextrusions. Thick aluminum extrusions may comeloose during operation and round aluminumextrusions cannot be secured firmly with this tool.8. Wood facingUse of wood facing helps to assure splinter-freecuts in workpieces. Attach a wood facing to theguide fence using the holes in the guide fence.See the figure concerning the dimensions for asuggested wood facing.Over 15mm (5/8") Over 420mm (16-1/2")1 150mm-60mm(2"-2-3/8")27mm (1-1/16")85mm(3-3/8")70mm(2-3/4")85mm(3-3/8")70mm(2-3/4")002206CAUTION:• Use straight wood of even thickness as the woodfacing.• Use screws to attach the wood facing to the guidefence. The screws should be installed so that thescrew heads are below the surface of the woodfacing.• When the wood facing is attached, do not turn theturn base with the handle lowered. The bladeand/or the wood facing will be damaged.9. Cutting repetitive lengths123001846When cutting several pieces of stock to the samelength, ranging from 220 mm (8-5/8") to 385 mm(15-1/8"), use of the set plate (optional accessory)will facilitate more efficient operation. Install the setplate on the holder (optional accessory) as shownin the figure.Align the cutting line on your workpiece with eitherthe left or right side of the groove in the kerf board,and while holding the workpiece from moving,move the set plate flush against the end of theworkpiece. Then secure the set plate with the screw.When the set plate is not used, loosen the screwand turn the set plate out of the way.NOTE:• Use of the holder-rod assembly (optionalaccessory) allows cutting repetitive lengths up to2,200 mm (7.2ft) approximately.10. Groove cutting1001563A dado type cut can be made by proceeding asfollows:Adjust the lower limit position of the blade using theadjusting screw and the stopper arm to limit thecutting depth of the blade. Refer to "Stopper arm"section described on previously.After adjusting the lower limit position of the blade,cut parallel grooves across the width of theworkpiece using a slide (push) cut as shown in thefigure. Then remove the workpiece materialbetween the grooves with a chisel. Do not attemptto perform this type of cut using wide (thick) bladesor with a dado blade. Possible loss of control andinjury may result.1. Cut grooves withblade1. Set plate2. Holder3. Screw1. Vise2. Spacer block3. Guide fence4. Aluminumextrusion5. Spacer block1. Holes
