196. Cutting aluminum extrusion (Fig. 43 & 44)When 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 the blade.CAUTION:• Never attempt to cut thick or round aluminumextrusions. Thick aluminum extrusions may comeloose during operation and round aluminum extrusionscannot be secured firmly with this tool.7. Wood facingUse of wood facing helps to assure splinter-free cuts inworkpieces. Attach a wood facing to the guide fenceusing the holes in the guide fence and 6 mm screws.See the figure concerning the dimensions for asuggested wood facing. (Fig. 45)CAUTION:• Use straight wood of even thickness as the woodfacing.• When cutting workpieces from 115 mm to 120 mmhigh, use a wood facing to prevent a portion of theworkpiece near the guide fence from being left uncut.Example:When cutting workpieces 120 mm high, use a woodfacing with the following thickness.006476CAUTION:• Use screws to attach the wood facing to the guidefence. The screws should be installed so that the screwheads are below the surface of the wood facing.• When the wood facing is attached, do not turn the turnbase with the handle lowered. The blade and/or thewood facing will be damaged.8. Groove cutting (Fig. 46)A 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 previously.After adjusting the lower limit position of the blade, cutparallel grooves across the width of the workpieceusing a slide (push) cut as shown in the figure. Thenremove the workpiece material between the grooveswith a chisel. Do not attempt to perform this type of cutusing wide (thick) blades or with a dado blade. Possibleloss of control and injury may result.CAUTION:• Be sure to return the stopper arm to the originalposition when performing other than groove cutting.Carrying tool (Fig. 1)Make sure that the tool is unplugged. Secure the blade at0° bevel angle and the turn base at right miter angle fully.Secure the slide poles after pulling the carriage towardyou fully. Lower the handle fully and lock it in the loweredposition by pushing in the stopper pin.Carry the tool by holding both sides of the tool base asshown in the figure. If you remove the holders, dust bag,etc., you can carry the tool more easily. (Fig. 47)CAUTION:• Always secure all moving portions before carrying thetool.• Stopper pin is for carrying and storage purposes onlyand not for any cutting operations.MAINTENANCECAUTION:• Always be sure that the tool is switched off andunplugged before attempting to perform inspection ormaintenance.WARNING:• Always be sure that the blade is sharp and clean for thebest and safest performance.Adjusting the cutting angleThis tool is carefully adjusted and aligned at the factory,but rough handling may have affected the alignment. Ifyour tool is not aligned properly, perform the following:1. Miter angle (Fig. 48)Push the carriage toward the guide fence and tightenthe knob to secure the carriage.Loosen the grip which secures the turn base. Turn theturn base so that the pointer points to 0° on the miterscale. Then turn the turn base slightly clockwise andcounterclockwise to seat the turn base in the 0° miternotch. (Leave as it is if the pointer does not point to 0°.)Loosen the hex bolts securing the guide fence usingthe socket wrench.Lower the handle fully and lock it in the loweredposition by pushing in the stopper pin. Square the sideof the blade with the face of the guide fence using atriangular rule, try-square, etc. Then securely tightenthe hex bolts on the guide fence in the order from theright side. (Fig. 49)Make sure that the pointer points to 0° on the miterscale. If the pointer does not point to 0°, loosen thescrew which secures the pointer and adjust the pointerso that it will point to 0°. (Fig. 50)2. Bevel angle(1) 0° bevel angle (Fig. 51)Push the carriage toward the guide fence andtighten the knob to secure the carriage. Lower thehandle fully and lock it in the lowered position bypushing in the stopper pin. Loosen the lever at therear of the tool. Make sure that the arm is locked.Turn the hex bolt on the left side of the arm two orthree revolutions counterclockwise. Turn the hexbolt on the right side of the arm two or threerevolutions counterclockwise to tilt the blade to theleft. (Fig. 52)Carefully square the side of the blade with the topsurface of the turn base using the triangular rule,try-square, etc. by turning the hex bolt on the rightside of the arm clockwise. Turn the hex bolt on theleft side of the arm clockwise as far as it will go.Then tighten the lever securely.
