English BEFORE CUTTING 1. Cutting a groove on the guard Handle Holder (A) Guard Vise Assembly Fence (B) 6mm Knob Bolt Workpiece Fence (A) Holder (A) has a guard (see Fig. 8) into which a groove must be cut. Loosen the 6mm knob bolt to retract the guard slightly. After placing a suitable wooden piece to sit on the fence and the table surfaces, fix it with the vise assembly. After the switch has been turned on and the saw blade has reached maximum speed, slowly lower the handle to cut a groove on the guard (C). CAUTION: Do not cut the groove too quickly; otherwise the guard might become damaged. Fig. 8 2. Positioning the table insert 6mm Machine Screw Workpiece Saw Blade 6mm Machine Screw Table insert Workpiece Saw Blade Table insert Workpiece Saw Blade Table insert 6mm Machine Screw [Right angle cutting] Fig. 9-a [Left bevel angle cutting] Fig. 9-b [Right bevel angle cutting] Fig. 9-c Table inserts are installed on the turntable. When shipping the tool from the factory, the table inserts are so fixed that the saw blade does not contact them. The burr of the bottom surface of the workpiece is remarkably reduced, if the table insert is fixed so that the gap between the side surface of the table insert and the saw blade will be minimum. Before using the tool, eliminate this gap in accordance with the following procedure. (1) Right angle cutting Loosen the three 6mm machine screws, then secure the left side table insert and temporarily tighten the 6mm machine screws of both ends. Then fix a workpiece (about 7-7/8" (200mm) wide) with the vise assembly and cut it off. After aligning the cutting surface with the edge of the table insert, securely tighten the 6mm machine screws of both ends. Remove the workpiece and securely tighten the 6mm center machine screw. Adjust the right hand table insert in the same way. (2) Left and right bevel angle cutting Adjust the table insert in the manner shown in Fig. 9-b and Fig. 9-c following the same procedure for right angle cutting. CAUTION: After adjusting the table insert for right angle cutting, the table insert will be cut to some extent if it is used for bevel angle cutting. When bevel cutting operation is required, adjust the table insert for bevel angle cutting. 3. Checking the saw blade lower limit position Check that the saw blade can be lowered 13/32" to 7/16" (10mm to 11mm) below the table insert as shown in Fig. 10-a. When you replace a saw blade with a new one, adjust the lower limit position so that the saw blade will not cut the turntable or complete cutting cannot be done. To adjust the lower limit position of the saw blade, follow the procedures (1) to (4) indicated below. (Fig. 10-b) Furthermore, when changing the position of a 8mm depth adjustment bolt that serves as a lower limit position stopper of the saw blade, it becomes necessary to shift the position of a 8mm hexagon socket set screw that is in the screw hole for the 8mm depth adjustment bolt that serves as the stopper. 13
