English Upon lowering the motor section, the lower guard is raised and the saw blade appears. Align the ink line with the saw blade. CAUTION In some arrangements when the turntable is rotated, the guard projects from the fence surface. Loosen the 6 mm knob bolt and push the guard to the retracted position. Never lift the lower guard while the saw blade is rotating. When cutting at an angle to the right or more, please slide the guard to the rear. The guard and sub-fence (A) and sub-fence (B) will not only make contact and adversely affect cutting accuracy, this could also result in damage to the guard. 11. Position adjustment of laser line Ink lining can be easily made on this tool to the laser marker. A switch lights up the laser marker (Fig. 15). Depending upon your cutting choice, the laser line can be aligned with the left side of the cutting width (saw blade) or the ink line on the right side. The laser line is adjusted to the width of the saw blade at the time of factory shipment. Adjust the positions of the saw blade and the laser line taking the following steps to suit the use of your choice. (1) Light up the laser marker and make a groove of about 5 mm deep on the workpiece that is about 20 mm in height and 150 mm in width. Hold the grooved workpiece by vise as it is and do not move it. For grooving work, refer to "24. Groove cutting procedures". (2) Then, turn the adjuster and shift the laser line. (If you turn the adjuster clockwise, the laser line will shift to the right and if you turn it counterclockwise, the laser line will shift to the left.) When you work with the ink line aligned with the left side of the saw blade, align the laser line with the left end of the groove (Fig. 16). When you align it with the right side of the saw blade, align the laser line with the right side of the groove. (3) After adjusting the position of the laser line, draw a right-angle ink line on the workpiece and align the ink line with the laser line. When aligning the ink line, slide the workpiece little by little and secure it by vise at a position where the laser line overlaps with the ink line. Work on the grooving again and check the position of the laser line. If you wish to change the laser line's position, make adjustments again following the steps from (1) to (3). WARNING ⅜ Make sure before plugging the power plug into the receptacle that the main body and the laser marker are turned off. ⅜ Exercise utmost caution in handling a switch trigger for the position adjustment of the laser line, as the power plug is plugged into the receptacle during operation. If the switch trigger is pulled inadvertently, the saw blade can rotate and result in unexpected accidents. ⅜ Do not remove the laser marker to be used for other purposes. CAUTION (Fig. 13 and Fig. 14) ⅜ Laser radiation - Do not stare into beam. ⅜ Laser radiation on work table. Do not stare into beam. If your eye is exposed directly to the laser beam, it can be hurt. ⅜ Do not dismantle it. ⅜ Do not give strong impact to the laser marker (main body of tool); otherwise, the position of a laser line can go out of order, resulting in the damage of the laser marker as well as a shortened service life. ⅜ Keep the laser marker lit only during a cutting operation. Prolonged lighting of the laser marker can result in a shortened service life. ⅜ Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. NOTE ⅜ Perform cutting by overlapping the ink line with the laser line. ⅜ When the ink line and the laser line are overlapped, the strength and weakness of light will change, resulting in a stable cutting operation because you can easily discern the conformity of lines. This ensures the minimum cutting errors. ⅜ In outdoor or near-the-window operations, it may become dificult to observe the laser line due to the sunlight. Under such circumstances, move to a place that is not directly under the sunlight and engage in the operation. ⅜ Do not tug on the cord behind the motor head or hook your finger, wood and the like around it; otherwise, the cord may come off and the laser marker may not be lit up. ⅜ Check and make sure on a periodic basis if the position of the laser line is in order. As regards the checking method, draw a right-angle ink line on the workpiece with the height of about 20 mm and the width of 150 mm, and check that the laser line is in line with the ink line [The deviation between the ink line and the laser line should be less than the ink line width (0.5 mm)]. (Fig. 17) 12. Digital display panel (for C12LSH) (Fig. 18 and Fig. 19) (1) Turning on the digital display switch shows 0° for both miter and bevel angle, regardless of main unit angle. (2) Align the main unit angle with the tilt angle (0°) and miter angle (0°) and hold down their reset buttons for at least 0.2 second. (3) Turning on the laser marker switch while the digital display switch is on, lights up the laser marker. (On the C12RSH, only the laser marker switch.) CAUTION ⅜ When operating the digital panel, have the motor head section at the top limit position and the blade stopped. ⅜ If the figure shown on the miter angle digital display is different from the positive stop angle (for example, 45.0° → 45.5°, 31.6° → 32.0°) then the positive stop has probably deviated slightly from its correct position. If this happens, do as follows. (1)Move the turntable left and right with the side handle loosened, and set the turntable to the correct position. (2)If the figures on the display and positive stop still do not match, then return the turntable to the 0° position. Next move the turntable left and right with the side handle loosened as shown in Fig. 20. After setting it to the correct position 0°, press the reset button again as shown in Fig. 18. NOTE ⅜ Before starting to cut, align the main unit to the miter angle 0° and the bevel angle 0° and hold down the reset buttons for at least 0.2 second. If you press the digital display switch to ON without aligning the main unit to 0°, then the figures appearing on the digital display and the main unit angle will not match. 58
