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
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.
CAUTION (Fig. 13 and Fig. 14)
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 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.
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.
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
When operating the digital panel, have the motor head
section at the top limit position and the blade stopped.
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
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.
