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
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 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
is
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.
15. Bevel cutting procedures (Fig. 18)
CAUTION
Ensure that the clamp lever is securely fixed when
beveling.
