English
(2) Align the main unit angle with the tilt angle (0°) and
miter angle (0°) and hold down their reset buttons for
at least 0.2 seconds.
(3) Turning on the laser marker switch while the digital
display switch is on, lights up the laser marker. (On
the C12FCH, only the laser marker switch.)
CAUTION
When operating the digital panel, have the motor head
section at the top limit position and the blade stopped.
If the figure shown on the miter angle digital display
is different from the positive stop angle (for example,
45.0° → 45.5°, 31.6° → 32.0°) then the positive stop
has probably deviated slightly from its correct
position. If this happens, do as follows.
(1) Move the turntable left and right with the side
handle loosened, and set the turntable to the
correct position.
(2) If the figures on the display and positive stop still
do not match, then return the turntable to the 0°
position. Next move the turntable left and right
with the side handle loosened as shown in Fig.
19. After setting it to the correct position 0°, press
the reset button again.
NOTE
Before starting to cut, align the main unit to the miter
angle 0° and the bevel angle 0° and hold down the
reset buttons for at least 0.2 seconds. If you press the
digital display switch to ON without aligning the main
unit to 0°, then the figures appearing on the digital
display and the main unit angle will not match.
The laser marker will not light up if the digital display
switch is turned off. (only on C12LCH)
Do not use the main unit near equipment that
generates electrical noise such as generators.
Electrical noise might cause faulty readings or
operation on the digital display.
9. Cutting operation
(1) As shown in Fig. 20 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.
(Only Model C12LCH/C12FCH)
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) Once the saw blade reaches maximum speed, slowly
push down the handle while pushing the lock lever
(D) 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.
10. Miter cutting procedures
(1) Loosen the side handle and push the lever for angle
stoppers. Then, adjust the turntable until the indicator
aligns with desired setting on the miter scale (Fig. 21).
(2) Re-tighten the side handle to secure the turntable in
the desired 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.
CAUTION
Never remove the side handle; use of the tool without
it would be hazardous.
To prevent an accident or personal injury always firmly
tighten the miter handle.
11. Bevel cutting procedures (Fig. 22)
(1) Loosen the clamp lever and bevel the saw blade to
the left.
(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
is 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 safety cover to be caught in the cutting groove of
the workpiece and to contact the saw blade.
12. Bevel angle fine adjustment (Fig. 23 and Fig. 24)
(1) Grip the handle on the motor head and position it at
the bevel angle you need. Temporarily tighten the
clamp lever.
CAUTION
If not tightened firmly enough the motor head might
suddenly move or slip, causing injuries. Be sure to
tighten the motor head section enough so it will not
move.
(2) Make fine adjustments to the bevel angle by gripping
the handle and moving the knob (A).
