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
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 difficult 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 38 mm and the width of 89
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. 14).

9. Cutting operation
(1) As shown in Fig. 15 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
desired.

(Only Model C10FCH2)
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) Once the saw blade reaches maximum speed, slowly
push down the handle 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.
