CAUTION
After adjusting the table insert for right angle cutting, the
table insert will be cut to some extent if it is used for bevel
angle cutting.
When bevel cutting operation is required, adjust the
table insert for bevel angle cutting.
4. Confi rmation for use of sub fence (Fig. 13)
This slide compound miter saw is equipped with a sub
fence. In the case of direct angle cutting and right bevel
angle cutting, use the sub fence. Then, you can do Left
bevel angle cutting, Right bevel angle cutting and Direct
angle cutting and realize stable cutting of the material
with a wide back face.
WARNING
In the case of left bevel cutting, turn the sub fence
counterclockwise (Fig.
counterclockwise, the main body or saw blade may
contact the sub fence, resulting in an injury.
5. Using an ink line (Adjusting the guard)
(1) Right angle cutting
Loosen the 6 mm knob bolt and contact the tip of the
guard with the workpiece.
Aligning the ink line on the workpiece with the groove of
the guard, the workpiece is cut on the ink line.
(2) Miter cutting and compound cutting (Miter cutting +
bevel cutting)
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 of 45° to the right or more,
please slide the guard to the rear.
The guard and sub-fence will not only make contact and
adversely aff ect cutting accuracy, this could also result in
damage to the guard.
6. Install the side handle (Fig. 1)
Install the side handle that came enclosed with this unit.
7. Position adjustment of laser line (Only Model
C8FSHE / C8FSHE(S))
Ink lining can be easily made on this tool to the laser
marker. A switch lights up the laser marker (Fig. 14).
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 "19. 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. 15). 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).
13). Unless it is turned
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. 16)
○ 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 specifi ed 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 diffi cult 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.
○ 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)
8. Cutting operation
(1) As shown in Fig. 18 the width of the saw blade is the
width of the cut. Therefore, slide the workpiece to the
right (viewed from the operator's position) when length
is desired, or to the left when length
If a laser marker is used, align the laser line with the left
side of the saw blade, and then align the ink line with the
laser line.
(2) After turning on the switch and checking that the saw
blade is rotating at maximum speed, slowly push down
the handle while holding down the lock lever and bring
the saw blade in the vicinity of the material to be cut.
(3) Once the saw blade contacts the workpiece, push the
handle down gradually to cut into the workpiece.
(4) After cutting the workpiece to the desired depth, turn the
power tool OFF and let the saw blade stop completely
before raising the handle from the workpiece to return it
to the full retract position.
CAUTION
○ For maximum dimensions
"SPECIFICATIONS" table.
○ Increased pressure on the handle will not increase the
cutting speed. On the contrary, too much pressure may
result in overload of the motor and/or decreased cutting
effi ciency.
