41. 3 3 Laser marker Use the laser marker for aligning with the ink line on the workpiece D Cutting position can be properly adjusted by aligning the positioning ink line with the laser line There is no need to make a long ink line on the workpiece 2 There is no need to lower the motor head to align with the marker ink line because the laser marker makes a laser line on the workpiece In addition cutting position can be easily adjusted because the operator can hold the workpiece with both hands to move 3 Cutting position can be easily adjusted because the laser line can be aligned with an optionally angled ink line 4 Even the workpieces such as crown moldings and base boards that have decorative surfaces and are difficult to be made an ink line can be cut just by aligning the laser line with the ink line on the fence side The laser line is adjusted to the width of the saw blade at the time of factory shipment Depending upon the user s 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 Adjust the position of the laser line according to 8 4 Position Adjustment of Laser Line on page 23 Workpiece rw moulding base board etc m tob ur WENN Laser line NS PISS cA 2 502 2 N Laser line Fig 4 b Fig 4 c 4 Miter and bevel angle fine adjustment The Model C 12LSH and C 12RSH are easily and finel
