WARNINGIn the case of left bevel cutting, remove the sub fence.Supposing it is not able to remove it, it will contactthe blade or some part of the tool, causing in seriousinjury to operator.

6. Using an ink lineUpon lowering the motor section, the lower guard israised and the saw blade appears.Align the ink line with the saw blade.

CAUTIONNever lift the lower guard while the saw blade isrotating.The sub fence will not only make contact andadversely affect cutting accuracy, this could also resultin damage to the guard.

7. Position adjustment of laser line (Only Model C10FCH)Ink lining can be easily made on this tool to the lasermarker. A switch lights up the laser marker (Fig. 8).Depending upon your cutting choice, the laser linecan 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 bladeat the time of factory shipment. Adjust the positionsof the saw blade and the laser line taking the followingsteps to suit the use of your choice.

Fig. 8

(1) Light up the laser marker and make a groove of about 5mm deep on the workpiece that is about 38 mm in heightand 89 mm in width. Hold the grooved workpiece by viseas it is and do not move it.

(2) Then insert a 4 mm hex. bar wrench in the 12 diameterhole on the side of the gear case, turn the hex. socketset screw to move the laser line. (If you turn the Hex.socket screw clockwise, the laser line will shift to theright and if you turn it counterclockwise, the laser linewill shift to the left.) When you work with the ink linealigned with the left side of the saw blade, align thelaser line with the left end of the groove (Fig. 9). Whenyou align it with the right side of the saw blade, alignthe laser line with the right side of the groove.

Fig. 9

(3) After adjusting the position of the laser line, draw aright-angle ink line on the workpiece and align theink line with the laser line. When aligning the ink line,slide the workpiece little by little and secure it by viseat a position where the laser line overlaps with theink line. Work on the grooving again and check theposition of the laser line. If you wish to change thelaser line’s position, make adjustments againfollowing the steps from (1) to (3).

WARNING (Fig. 10 and Fig. 11)� Make sure before plugging the power plug into the

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, itcan 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 linecan go out of order, resulting in the damage of thelaser marker as well as a shortened service life.

� Keep the laser marker lit only during a cuttingoperation. Prolonged lighting of the laser marker canresult in a shortened service life.

� Use of controls or adjustments or performance ofprocedures other than those specified herein mayresult in hazardous radiation exposure.

NOTE

� Perform cutting by overlapping the ink line with thelaser 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 youcan easily discern the conformity of lines. This ensuresthe minimum cutting errors.

� In outdoor or near-the-window operations, it maybecome difficult to observe the laser line due to thesunlight. Under such circumstances, move to a placethat is not directly under the sunlight and engage inthe operation.

� Do not tug on the cord behind the motor head or hookyour finger, wood and the like around it; otherwise,the cord may come off and the laser marker may notbe lit up.

� Check and make sure on a periodic basis if the positionof the laser line is in order. As regards the checkingmethod, draw a right-angle ink line on the workpiecewith the height of about 38 mm and the width of 89mm, and check that the laser line is in line with theink line [The deviation between the ink line and thelaser line should be less than the ink line width (0.5mm)] (Fig. 12).

Fig. 12

8. Cutting operation(1) As shown in Fig. 13 the width of the saw blade is the

width of the cut. Therefore, slide the workpiece to theright (viewed from the operator’s position) whenlength is desired, or to the left when length isdesired.

Fig. 13

(Only Model C10FCH)If a laser marker is used, align the laser line with theleft side of the saw blade, and then align the ink linewith the laser line.

(2) Once the saw blade reaches maximum speed, slowlypush down the handle and bring the saw blade in thevicinity of the material to be cut.

(3) Once the saw blade contacts the workpiece, push thehandle down gradually to cut into the workpiece.

(4) After cutting the workpiece to the desired depth, turnthe power tool OFF and let the saw blade stopcompletely before raising the handle from theworkpiece 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 pressuremay result in overload of the motor and/or decreasedcutting efficiency.

� Confirm that the trigger switch is turned OFF and thepower plug has been removed from the receptaclewhenever the tool is not in use.

� Always turn the power off and let the saw blade stopcompletely before raising the handle from theworkpiece. If the handle is raised while the saw bladeis still rotating, the cut-off piece may become jammedagainst the saw blade causing fragments to scatterabout dangerously.

� Every time one cutting of deep-cutting operation isfinished, turn the switch off, and check that the sawblade has stopped. Then raise the handle, and returnit to the full retract position.

� Be absolutely sure to remove the cut material fromthe top of the turntable, and then proceed to the nextstep.
