NOTE:
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
1-1/2" (38mm) and the width of 3-1/2" (89mm), 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 (0.5mm)]. (Fig. 20)
Ink lining can be easily made on this tool to the laser marker. A
switch lights up the laser marker. (Fig. 17)
Turning on the laser marker switch while the digital display swich
is on, light up the laser marker. (On the C12FDH, only the laser
marker switch.)
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 3/16"
(5mm) deep on the workpiece that is about 1-1/2" (38mm) in
height and 3-1/2"(89mm) in width. Hold the grooved workpiece
by vise as it is and do not move it. (Fig. 18)
(2) Then insert a 4mm hex. bar wrench in the 12 diameter hole on
the side of the gear case, turn the hex. socket set screw to move
the laser line. (If you turn the Hex. socket screw clockwise, the
laser line will shift to the right and if you turn it counterclockwise,
Turn
the laser line will shift to the left.) When you work with the ink
12 diameter
line aligned with the left side of the saw blade, align the laser
hole
line with the left end of the groove. (Fig. 19) 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
Laser line
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).
