(2) The screw holder can be raised or lowered according

to the height of the workpiece by loosening the 6 mm

wing bolt (B). After the adjustment, firmly tighten the

6 mm wing bolt (B) and fix the screw holder.

(3) Turn the upper knob and securely fix the workpiece

in position.

WARNING

⅜ Always firmly clamp or vise to secure the workpiece

to the fence; otherwise the workpiece might be thrust

from the table and cause bodily harm.

CAUTION

⅜ Always confirm that the motor head does not contact

the vise assembly when it is lowered for cutting. If

there is any danger that it may do so, loosen the 6

mm wing bolt and move the vise assembly to a

position where it will not contact the saw blade.

5. Confirmation for use of sub fence (Fig. 11)

This power tool is equipped with a sub fence. In the

case of direct angle cutting use the sub fence. Then,

you can realize stable cutting of the material with a

wide back face. In the case of left bavel cutting, raise

the sub fence up as illustrated in Fig. 11 and then turn

it counterclockwise.

WARNING

⅜ In the case of left bevel cutting, turn the sub fence

counterclockwise (Fig. 8). Unless it is turned

counterclockwise, the main body or saw blade may

contact the sub fence, resulting in an injury.

6. Using an ink line

Upon lowering the motor section, the lower guard is

raised and the saw blade appears.

Align the ink line with the saw blade.

CAUTION

Never lift the lower guard while the saw blade is

rotating.

The sub fence will not only make contact and

adversely affect cutting accuracy, this could also result

in damage to the guard.

7. Position adjustment of laser line (Only Model

C12LCH/C12FCH)

Ink lining can be easily made on this tool to the laser

marker. A switch lights up the laser marker (Fig. 12).

Turning on the laser marker switch while the digital

display switch is on, light up the laser marker. (On

the C12FCH, 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 5

mm deep on the workpiece that is about 38 mm in height

and 89 mm in width. Hold the grooved workpiece by vise

as it is and do not move it.

(2) Then insert a 4 mm 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, 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. 13). 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 (Fig. 15 and Fig. 16)

⅜ Make sure before plugging the power plug into the

receptacle that the main body and the laser marker

are turned off.

⅜ 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.

⅜ Do not remove the laser marker to be used for other

purposes.

CAUTION

⅜ Laser radiation - Do not stare into beam.

⅜ Laser radiation on work table. Do not stare into beam.

If your eye is exposed directly to the laser beam, it

can be hurt.

⅜ Do not dismantle it.

⅜ 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.

⅜ Keep the laser marker lit only during a cutting

operation. Prolonged lighting of the laser marker can

result in a shortened service life.

⅜ Use of controls or adjustments or performance of

procedures other than those specified herein may

result in hazardous radiation exposure.

NOTE

⅜ Perform cutting by overlapping the ink line with the

laser line.

⅜ 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.

⅜ 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.

⅜ 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.

⅜ 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).

8. Digital display panel (for C12LCH and C12LC) (Fig. 17

and Fig. 18)

(1) Turning on the digital display switch shows 0° for both

miter and bevel angle, regardless of main unit angle.
