English
○ 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.
○ Be absolutely sure to remove the cut material from the
top of the turntable, and then proceed to the next step.
9. Cutting narrow workpieces (Press cutting) (Fig. 19)
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.
10. Cutting large workpieces (Fig. 20, 21)
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 6 mm fl at head screws
and the 6 mm nuts using the 7 mm holes on the fence
surface (two holes on each side). (Fig. 20)
Refer to "SPECIFICATIONS" for the thickness of the
auxiliary board.
NOTE
When cutting a workpiece exceeding 65 mm in height in
right-angle cutting or 60 mm in left bevel angle cutting or
45 mm in right bevel angle cutting, adjust the lower limit
position so that the base of the motor head will not come
in contact with the workpiece.
To adjust the lower limit position of the saw blade, follow the
procedure (1) shown in Fig. 21.
(1) Lower the motor head, and turn the 6 mm depth
adjustment bolt and make adjustments so that there can
be a clearance of 2 mm to 3 mm between the lower limit
position of the motor head and the top of the workpiece
at the saw blade's lower limit position where the head of
the 6 mm depth adjustment bolt contacts the hinge.
11. Cutting wide workpieces (Slide cutting) (Fig. 22)
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.
12. 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. 23).
(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.
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.
13. Bevel cutting procedures (Fig. 24)
(1) Loosen the clamp lever and bevel the saw blade to the
left or to the right. When tilting the motor head to the right
pull the set pin towards the rear.
NOTE
Loosen the clamp lever, tilt the main unit to the left and
then pull the set pin to enable 48-degree cuts.
Loosen the clamp lever and slant to the left a little at a
time while pushing the set pin into the main unit. At this
time, the set pin will enter one step and fi t into the 30° left
slant and 33.9° left slant setting slots.
With the set pin in the slot as described above, setting
to the 30° left slant position is possible by pushing to the
right side.
Also, with the set pin in the slot as described above,
setting to the 33.9° left slant position is possible by
pushing to the left side.
(2) Adjust the bevel angle to the desired setting
while watching the bevel angle scale and indicator,
then secure the clamp lever.
WARNING
When the workpiece is secured on the left or right side
of the blade, the short cut-off portion will come to rest
on the right or left side of the saw blade. 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.
When stopping the bevel cutting operation halfway, start
cutting after pulling back the motor head to the initial
position.
Starting from halfway, without pulling back, causes the
lower guard to be caught in the cutting groove of the
workpiece and to contact the saw blade.
14. Compound cutting procedures
Compound cutting can be performed by following the
instructions in 13 and 14 above. For maximum dimensions
for compound cutting, refer to "SPECIFICATIONS" table.
CAUTION
Always secure the workpiece with the right or left
hand and cut it by sliding the round portion of the saw
backwards with the left hand.
It is very dangerous to rotate the turntable to the left
during compound cutting because the saw blade may
come into contact with the hand that is securing the
workpiece.
In case of compound cutting (angle + bevel) by
left bevel, turn the sub-fence (optional accessory)
counterclockwise, and engage in the cutting operation.
15. Cutting long materials
When cutting long materials, use an auxiliary platform
which is the same height as the holder (optional
accessory) and base of the special auxiliary equipment.
Capacity: wooden material (W × H × L)
300 mm × 45 mm × 1050 mm, or
180 mm × 25 mm × 1600 mm
16. Installing the holders ... (Optional accessory)
The holders help keep longer workpieces stable and in
place during the cutting operation.
(1) As indicated in Fig. 25, use a steel square for aligning
the upper edge of the holders with the base surface.
Loosen the 6 mm wing nut. Turn a height adjustment bolt
6 mm, and adjust the height of the holder.
(2) After adjustment, fi rmly tighten the wing nut and fasten
the holder with the 6 mm knob bolt (optional accessory). If
the length of Height Adjustment Bolt 6 mm is insuffi cient,
spread a thin plate beneath. Make sure the end of Height
Adjustment Bolt 6 mm does not protrude from the holder.
