8Finishing edges (Fig. 15)To trim edges or make dimensional adjustments, run theblade lightly along the cut edges.Metal cuttingAlways use a suitable coolant (cutting oil) when cuttingmetal. Failure to do so will cause significant blade wear.The underside of the workpiece can be greased insteadof using a coolant.Dust extraction (Fig. 16)Clean cutting operations can be performed by connectingthis tool to a Makita vacuum cleaner. Insert the hose ofthe vacuum cleaner into the hole at the rear of the tool.Lower the dust cover before operation.CAUTION:Dust extraction cannot be performed when making bevelcuts.Rip fence set (optional accessory)CAUTION:Always be sure that the tool is switched off andunplugged before installing or removing accessories.1) Straight cuts (Fig. 17 & 18)When repeatedly cutting widths of 160 mm or less,use of the rip fence will assure fast, clean, straightcuts. To install, insert the rip fence into the rectangu-lar hole on the side of the tool base with the fenceguide facing down. Slide the rip fence to the desiredcutting width position, then tighten the bolt to secureit.2) Circular cuts (Fig. 19 & 20)When cutting circles or arcs of 170 mm or less inradius, install the rip fence as follows.Insert the rip fence into the rectangular hole on theside of the tool base with the fence guide facing up.Insert the circular guide pin through either of the twoholes on the fence guide. Screw the threaded knobonto the pin to secure the pin. Now slide the ripfence to the desired cutting radius, and tighten thebolt to secure it in place. Then move the tool base allthe way forward.NOTE:Always use blades No. B-17, B-18, B-26 or B-27when cutting circles or arcs.Anti-splintering device (optional accessory)(Fig. 21)For splinter-free cuts, the anti-splintering device can beused. To install the anti-splintering device, move the toolbase all the way forward and insert it between the twoprotrusions of the tool base.CAUTION:The anti-splintering device cannot be used when makingbevel cuts.MAINTENANCECAUTION:Always be sure that the tool is switched off andunplugged before carrying out any work on the tool.To maintain product safety and reliability, repairs, mainte-nance or adjustment should be carried out by a MakitaAuthorized Service Center.
