5. Repositioning riving knife (Fig. 51)
The position of riving knife (Fig. 51-A) should be
changed as follows.
(1) Loosen the clamping nut and hold the lower blade
guard A using its lug by hand. (Fig. 51-B)
(2) While holding the lower blade guard A, pull the
riving knife so that it turns and pivot it to the posi-
tion in the direction of arrow. (Fig. 51-C)
(3) With the riving knife held in that position, return
the lower blade guard A to the original position
and tighten the clamping nut securely. (Fig. 51-D
& E)
6. Installing or removing the sub fences R and L
(Fig. 52)
CAUTION:
• When cutting a workpiece over 20 mm thick, make sure
that the sub fences R and L are securely installed with
a screw.
Removal of the sub fences R and L are convenient for
cutting wide and thin workpiece.
When cutting a workpiece up to 20 mm thick and more
than 180 mm wide, remove the sub fences R and L by
removing the screw shown in the figure.
When cutting a workpiece over 20 mm thick, install the
sub fences R and L securely with a screw.
Refer to the table below for the relation between the size
of workpiece and use/unuse of sub fences R and L.
(Fig. 53)
Workpiece size (H x W)
1 68 mm x 155 mm
2 20 mm x 210 mm
OPERATION
CAUTION:
• Before use, be sure to release the handle from the low-
ered position by pulling the stopper pin and turning it to
the angle of 90°.
• Make sure the blade is not contacting the workpiece,
etc. before the switch is turned on.
CUTTING AS MITER SAW
WARNING:
• Make sure that the lower blade guard C is installed
before using in miter saw mode.
CAUTION:
• Do not apply excessive pressure on the handle when
cutting. Too much force may result in overload of the
motor and/or decreased cutting efficiency. Push down
handle with only as much force as is necessary for
smooth cutting and without significant decrease in
blade speed.
• Gently press down the handle to perform the cut. If the
handle is pressed down with force or if lateral force is
applied, the blade will vibrate and leave a mark (saw
mark) in the workpiece and the precision of the cut will
be impaired.

Use/Unuse of subfence
With sub fences
Without sub fences
1. Press cutting
Secure the workpiece against guide fence and turn
table. Switch on the tool without the blade making any
contact and wait until the blade attains full speed
before lowering. Then gently lower the handle to the
fully lowered position to cut the workpiece. When the
cut is completed, switch off the tool and WAIT UNTIL
THE BLADE HAS COME TO A COMPLETE STOP
before returning the blade to its fully elevated position.
2. Miter cutting
Refer to the previously covered "Adjusting the miter
angle".
3. Bevel cut
Loosen the lever and tilt the saw blade to set the bevel
angle (Refer to the previously covered "Adjusting the
bevel angle"). Be sure to retighten the lever firmly to
secure the selected bevel angle safely. Secure the
workpiece against guide fence and turn table. Switch
on the tool without the blade making any contact and
wait until the blade attains full speed. Then gently
lower the handle to the fully lowered position while
applying pressure in parallel with the blade. When the
cut is completed, switch off the tool and WAIT UNTIL
THE BLADE HAS COME TO A COMPLETE STOP
before returning the blade to its fully elevated position.
CAUTION:
• Always be sure that the blade will move down to bevel
direction during a bevel cut. Keep hands out of path of
saw blade.
• During a bevel cut, it may create a condition whereby
the piece cut off will come to rest against the side of the
blade. If the blade is raised while the blade is still rotat-
ing, this piece may be caught by the blade, causing
fragments to be scattered which is dangerous. The
blade should be raised ONLY after the blade has come
to a complete stop.
• When pressing the handle down, apply pressure paral-
lel to the blade. If the pressure is not parallel to the
blade during a cut, the angle of the blade might be
shifted and the precision of the cut will be impaired.
4. Compound cutting
Compound cutting is the process in which a bevel
angle is made at the same time in which a miter angle
is being cut on a workpiece. Compound cutting can be
performed at angle shown in the table.
Bevel angle
45°
When performing compound cutting, refer to "Press
cutting", "Miter cutting" and "Bevel cut" explanations.
5. Cutting aluminum extrusion (Fig. 56)
When securing aluminum extrusions, use spacer
blocks or pieces of scrap as shown in the figure to pre-
vent deformation of the aluminum. Use a cutting lubri-
cant when cutting the aluminum extrusion to prevent
buildup of the aluminum material on the blade.
CAUTION:
• Never attempt to cut thick or round aluminum extru-
sions. Thick aluminum extrusions may come loose dur-
ing operation and round aluminum extrusions cannot
be secured firmly with this tool.
• Never cut aluminum in the table saw mode (bench
mode).
Miter angle
Left and Right 0 – 45°
