English
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.
9. 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. 15).
(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.
10. Bevel cutting procedures (Fig. 16)
(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.

11. Compound cutting procedures
Compound cutting can be performed by following the
instructions in 9 and 10 above. For maximum
dimensions for compound cutting, refer to
"SPECIFICATIONS" table.
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.
12. Installing the holders (Optional accessory)
The holders help keep longer workpieces stable and
in place during the cutting operation.
(1) As indicated in Fig. 17, 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, firmly 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 insufficient, spread a thin plate beneath. Make
sure the end of Height Adjustment Bolt 6 mm does
not protrude from the holder.
13. Stopper for precision cutting (Stopper and holder are
optional accessory)
The stopper facilitates continuous precision cutting
in lengths of 280 mm to 450 mm.
To install the stopper, attach it to the holder with the
6 mm wing bolt as shown in Fig. 18.
14. Confirmation for use Crown molding vise, Crown
molding Stopper (L) and (R) (Optional accessory)
(1) Crown molding Stopper (L) and (R) (optional
accessories) allow easier cuts of crown molding
without tilting the saw blade. Install them in the base
both-sides side to be shown in Fig. 19. After inserting
tighten the 6 mm knob bolts to secure the Crown
molding Stoppers.
(2) The crown molding vise (B) (Optional accessory) can
be mounted on either the left fence (Fence (B)) or the
right fence (Fence (A)). It can unite with the slope of
the crown molding and vice can be pressed down.
Then turn the upper knob, as necessary, to securely
attach the crown molding in position. To raise or lower
the vise assembly, first loosen the 6 mm wing bolt.
After adjusting the height, firmly tighten the 6 mm
wing bolt; then turn the upper knob, as necessary, to
securely attach the crown molding in position (See
Fig 20).
Position crown molding with its WALL CONTACT
EDGE against the guide fence and its CEILING
CONTACT EDGE against the Crown molding Stoppers
as shown in Fig. 20. Adjust the Crown molding
Stoppers according to the size of the crown molding.
Tighten the 6 mm wing bolt to secure the Crown
molding Stoppers.
WARNING
Always firmly clamp or vise to secure the crown
molding to the fence; otherwise the crown molding
might be thrust from the table and cause bodily harm.
Do not bevel cutting. The main body or saw blade
may contact the sub fence, resulting in an injury.
