CAUTION:
Always confi rm that the motor head (see Fig. 1) does not contact
the vise assembly when it is lowered for cutting. If there is any
danger that it may do so, loosen the 6 mm wing bolt (B) and move
the vise assembly to a position where it will not contact the saw
blade.
3. Cutting Operation
(1) As shown in Fig. 22 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 ⓐ is
desired.
(Only Model C10FCH2)
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, push the handle down
carefully until the saw blade approaches the workpiece.
(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.

WARNING:
∗ 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.
∗ When you cut the workpiece, avoid any cutoff thinner than
the clearance between the cutting edge and the saw blade.
Otherwise, the cut-off material can enter the clearance between
the cutting edge and the saw blade and scatter around you,
resulting in an injury.
CAUTION:
∗ 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 effi ciency.
∗ If the handle is pressed down with excessive or lateral force, the
saw blade may vibrate during the cutting operation and cause
unwanted cutting marks on the workpiece, thus reducing the
quality of the cut. Accordingly, press the handle down gently
and carefully.
4. 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. 23).
(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 fi rmly tighten the
miter handle.
5. Bevel cutting procedures
(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 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.
6. Compound cutting procedures
Compound cutting can be performed by following the instructions in 4
and 5 above. For maximum dimensions for compound cutting, refer to
"SPECIFICATIONS" table on page 6.
CAUTION:
Always secure the workpiece with the right hand side for compound
cutting. Never rotate the table to the right for compound cutting,
because the saw blade might then contact the clamp or vise that
secures the workpiece, and cause personal injury or damage.
7. Crown molding cutting procedures
Fig. 25 shows two common crown molding types having angles of (θ) 38°
and 45°.
