8. Install the side handle (Fig. 1)
Install the side handle that came enclosed with this unit.
9. Position adjustment of laser line (Only Model C8FSHE)
Ink lining can be easily made on this tool to the laser marker. A switch lights
up the laser marker (Fig. 11).
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 "21. 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. 12). 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. 13)
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 dificult 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 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. 14)
10. 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
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 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 efficiency.
Confirm 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 finished, turn the switch
off, and check that the saw blade has stopped. Then raise the handle, and
return it to the full retract position.
Be absolutely sure to remove the cut material from the top of the turntable,
and then proceed to the next step.
11. Cutting narrow workpieces (Press cutting)
Slide the hinge down to holder (A), then tighten the slide securing knob (Fig.
2). Lower the handle to cut the workpiece. Using the power tool this way will
permit cutting of workpieces of up to 65 mm square.
12. Cutting large workpieces
There may be case when a complete cutting cannot be done depending on
the height of workpiece. In this case, mount an auxiliary board with the 6mm
flat head screws and the 6mm nuts using the 7mm holes on the fence surface
(two holes on each side). (Fig. 16)
Refer to "SPECIFICATIONS" for the thickness of the auxiliary board.
13. Cutting wide workpieces (Slide cutting)
Loosen the slide securing knob (Fig. 2), grip the handle and slide the saw
blade forward. Then press down on the handle and slide the saw blade back
to cut the workpiece. This facilitates cutting of workpieces of up to 312 mm
in width.
WARNING
Never put your hand on the side handle during the cutting operation because
the saw blade comes close to the side handle when the motor head is lowered.
14. Miter cutting procedures
(1) Loosen the side handle and pull up the lever for angle stoppers. Then, adjust
the turntable until the indicator aligns with desired setting on the miter scale
(Fig. 17).
(2) Re-tighten the side handle to secure the turntable in the desired position.
(3) The miter scale indicates both the cutting angle on the angle scale and the
gradient on the grade scale.
(4) The gradient, which is the ratio of the height to the base of the triangular
section to be removed, may be used for setting the miter scale instead of
the cutting angle, if desired.
(5) Therefore, to cut a workpiece at a grade of 2/10, set the indicator to position.
NOTE
Positive stops are provided at the right and left of the 0° center setting, at
15°, 22.5°, 31.6° and 45° settings.
Check that the miter scale and the tip of the indicator are properly aligned.
Operation of the saw with the miter scale and indicator out of alignment, or
with the side handle not properly tightened, will result in poor cutting
precision.
