(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 “13.Groove cutting procedures” on page 19.

*Laser radiation- Do not stare into beam.

*Laser radiation on work table. Do not stare into beam. If your eye is exposed directly to the laser beam, it can be hurt.

*Do not dismantle it.

*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.

*Keep the laser marker lit only during a cutting operation. Prolonged lighting of the laser marker can result in a shortened service life.

*Use of controls or adjustments or performance of procedures other than those specified herein may

result in hazardous radiation exposure.

NOTE

*Perform cutting by overlapping the ink line with the laser line.

*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.

*In outdoor or near-the-window operations, it may become difficult 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.

*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.

Ink lining can be easily made on this tool to the laser marker. A switch lights up the laser marker. (Fig. 20) 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.

(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. 22) 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).
