251. Cutting aluminum extrusionWhen securing aluminum extrusions, use spacer blocksor pieces of scrap as shown in the figure to preventdeformation of the aluminum. Use a cutting lubricantwhen cutting the aluminum extrusion to prevent build-upof the aluminum material on the blade.CAUTION:• Never attempt to cut thick or round aluminum extrusions.Thick aluminum extrusions may come loose duringoperation and round aluminum extrusions cannot besecured firmly with this tool.2. Groove cuttingA dado type cut can be made by proceeding as follows:Adjust the lower limit position of the blade using theadjusting screw and the stopper arm to limit the cuttingdepth of the blade. Refer to “Stopper arm” sectiondescribed on previously.After adjusting the lower limit position of the blade, cutparallel grooves across the width of the workpiece usinga slide (push) cut as shown in the figure. Then removethe workpiece material between the grooves with achisel. Do not attempt to perform this type of cut usingwide (thick) blades or with a dado blade. Possible loss ofcontrol and injury may result.CAUTION:• Be sure to return the stopper arm to the original positionwhen performing other than groove cutting.Carrying toolMake sure that the tool is unplugged. Secure the blade at 0°bevel angle and the turn base at right miter angle fully.Secure the slide poles after pulling the carriage toward youfully. Lower the handle fully and lock it in the lowered positionby pushing in the stopper pin.1. Guide fence2. Vise3. Spacer block4. Aluminum extrusion5. Spacer block123450015611.
