Holders and holder assembly (optional
accessories)
The holders and the holder assembly can be installed on
either side as a convenient means of supporting work-
pieces horizontally. Install them as shown in the figure.
Then tighten the screws firmly to secure the holders and
the holder assembly. (Fig. 40)
When cutting long workpieces, use the holder-rod
assembly (optional accessory). It consists of two holder
assemblies and two rods 12. (Fig. 41)
CAUTION:
• Always support long workpieces level with the top sur-
face of the turn base for accurate cuts and to prevent
dangerous loss of control of the tool.
OPERATION
CAUTION:
• Before use, be sure to release the handle from the low-
ered position by pulling the stopper pin.
• Make sure the blade is not contacting the workpiece,
etc. before the switch is turned on.
CUTTING AS MITER SAW
WARNING:
• When using the tool in the miter saw mode, secure the
top table at the topmost position so that the saw blade
never protrudes from the top surface of the top table.
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.
1. Press cutting (Fig. 42)
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 (Fig. 43)
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 work-
piece 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.
• (Only for European countries) always set the sub-fence
outside when performing left bevel cuts.
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°
006366
When performing compound cutting, refer to "Press cut- ting", "Miter cutting" and "Bevel cut" explanations.
5. Cutting aluminum extrusion (Fig. 44)
When securing aluminum extrusions, use spacer blocks
or pieces of scrap as shown in the figure to prevent defor-
mation of the aluminum. Use a cutting lubricant when
cutting the aluminum extrusion to prevent build-up 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).
