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

case of direct angle cutting and right bevel angle cutting,

use the sub fence (B). Then, you can realize stable

cutting of the material with a wide back face. When left

angle cutting, loosen the 6 mm wing bolt, then slide the

sub fence (B) outward, as shown in Fig. 13.

6. 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 (A) and sub-fence (B) will not

only make contact and adversely aﬀ ect cutting accuracy,

this could also result in damage to the guard.

7. 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. 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).

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 is desired.

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 lever (A) 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 for cutting, refer to

“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.

○ Conﬁ rm that the trigger switch is turned OFF and the

power plug has been removed from the receptacle

whenever the tool is not in use.

○ Always turn the power oﬀ and let the saw blade stop

completely before raising the handle from the workpiece.

If the handle is raised while the saw blade is still rotating,

the cut-oﬀ piece may become jammed against the saw

blade causing fragments to scatter about dangerously.

○ Every time one cutting of deep-cutting operation is

ﬁ nished, turn the switch oﬀ , and check that the saw

blade has stopped. Then raise the handle, and return it

to the full retract position.
