Position Adjustment Of Laser Line (Only Model C 10Fsh) - Hitachi C 10FSB Technical Data And Service Manual

8-4. Position Adjustment of Laser Line (Only Model C 10FSH)

The laser line is adjusted to the width of the saw blade at the
time of factory shipment. Depending upon the cutting choice,
align the laser line with the left side of the cutting width (saw
blade) or the right side according to the following procedure.
First, make a right-angle ink line on the workpiece that is about
20 mm (25/32") in height and 150 mm (5-29/32") in width.
To cut the right side of the ink line with the saw blade as shown
in Fig. 31, align the left side of the saw blade with the ink line
on the workpiece and make a groove of about 5 mm deep on
the workpiece to the middle. Hold the grooved workpiece by
the vise as it is and do not move it. (For grooving work, refer to
the Instruction Manual "Groove cutting procedures".)
Light up the laser marker. Turn the adjuster to align the laser
line with the ink line. (Turning the adjuster clockwise will shift
the laser line position to the right and turning counterclockwise
will shift to the left.) (Fig. 32)
Thus the cutting position matches the laser line position. Align
the ink line on the workpiece 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
(Fig. 33). Work on the grooving again and check the position
of 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.
WARNING:
Make sure before plugging the power plug into the receptacle
that the main body and the laser marker are turned off.
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.
Do not remove the laser marker to be used for other purposes.
