9Installing or removing trimmer bit (Fig. 4)CAUTION:• Do not tighten the collet nut without inserting a bit, orthe collet cone will break.• Use only the wrenches provided with the tool.Insert the bit all the way into the collet cone and tightenthe collet nut securely with the two wrenches.To remove the bit, follow the installation procedure inreverse.Installing trimmer shoe(after it has been removed from the tool) (Fig. 5)NOTE:• The trimmer shoe is factory installed on the tool.Use the bolts, wing nuts, spring washers and flat wash-ers to install the trimmer shoe as shown in Fig. 5.OPERATIONTurn the tool on without the bit making any contact withthe workpiece and wait until the bit attains full speed.Then move the tool over the workpiece surface, keepingthe tool base and trimmer shoe flush with the sides of theworkpiece. (Fig. 6)(Note)• This tool can be used as a conventional trimmer whenyou remove the trimmer shoe.When doing edge cutting, the workpiece surface shouldbe on the left side of the bit in the feed direction. (Fig. 7)NOTE:• Moving the tool forward too fast may cause a poor qual-ity of cut, or damage to the bit or motor. Moving the toolforward too slowly may burn and mar the cut. Theproper feed rate will depend on the bit size, the kind ofworkpiece and depth of cut. Before beginning the cuton the actual workpiece, it is advisable to make a sam-ple cut on a piece of scrap lumber. This will showexactly how the cut will look as well as enable you tocheck dimensions.• When using the trimmer shoe, the straight guide or thetrimmer guide, be sure to keep it on the right side in thefeed direction. This will help to keep it flush with theside of the workpiece. (Fig. 8)CAUTION:• Since excessive cutting may cause overload of themotor or difficulty in controlling the tool, the depth of cutshould not be more than 3 mm at a pass when cuttinggrooves. When you wish to cut grooves more than3 mm deep, make several passes with progressivelydeeper bit settings.Templet guideThe templet guide provides a sleeve through which the bit passes, allowing use of the trimmer with templet patterns.(Fig. 9)Remove the tool base from the tool. Loosen the wing bolts and secure the tool base horizontally. Loosen the twoscrews on the tool base. (Fig. 10)Place the templet guide on the tool base. There are four convex portions on the templet guide. Secure two of the fourconvex portions using the two screws. Install the tool base on the tool. (Fig. 11)Secure the templet to the workpiece. Place the tool on the templet and move the tool with the templet guide slidingalong the side of the templet. (Fig. 12)NOTE:• The workpiece will be cut a slightly different size from the templet. Allow for the distance (X) between the router bitand the outside of the templet guide. The distance (X) can be calculated by using the following equation:Straight guide (Accessory) (Fig. 13, 14, 15 & 16)Attach the guide plate to the straight guide with the boltand the wing nut.Circular workCircular work may be accomplished if you assemble thestraight guide and guide plate as shown in Fig. 17 or 18.Min. and max. radius of circles to be cut (distancebetween the center of circle and the center of bit) are asfollows:Min.: 70 mmMax.: 221 mmFig. 17 for cutting circles between 70 mm and 121 mm inradius.Fig. 18 for cutting circles between 121 mm and 221 mmin radius.Note:• Circles between 172 mm and 186 mm in radius cannotbe cut using this guide.Align the center hole in the straight guide with the centerof the circle to be cut. Drive a nail less than 6 mm indiameter into the center hole to secure the straight guide.Pivot the tool around the nail in clockwise direction.(Fig. 19)Distance (X) = outside diameter of the templet guide – router bit diameter2
