If you connect a vacuum cleaner to your saw, more effi-
cient and cleaner operations can be performed.
To install the blade cover when using in the table saw
mode (bench mode), turn the turn base to 0° miter angle
(see the section titled "Adjusting miter angle") and place
the blade cover on the turn table so that the blade cover
is centered over the slit for the blade entrance in the turn
table and then lock the handle in the lowest position by
fully pushing in the stopper pin as shown in the figure.
(Fig. 33)
NOTE:
• To attach the dust bag to the front dust nozzle in the
table saw mode (bench mode), first remove the cap
from the front dust nozzle and then attach the dust bag
to the dust nozzle.
• When not in use of dust bag, always replace the cap to
the front dust nozzle. Failure to do so result in dust
scattering from the nozzle.
• When using the tool in the table saw mode (bench
mode), make sure that the blade cover is installed on
the turn table.
Securing workpiece
Whenever possible, secure the workpiece with the
optional vise. If you must use your hand to hold the work-
piece, then it must be done firmly and securely so as not
to lose control of the workpiece. Your hand and arm must
be kept well away from the blade area (100 mm mini-
mum). Squeeze the workpiece firmly against the guide
fence with your fingers held over the top of the guide
fence. The workpiece must also rest steadily on the turn
base.
WARNING:
• Never use your hand to hold the workpiece that
requires your hand to be any closer than 100 mm from
the blade area. In this case, always use the optional
vise to secure the workpiece. After any cutting opera-
tion, raise the blade gently. Never raise the blade until it
has come to a complete stop. Serious injury may result.
CAUTION:
• When cutting long workpieces, use supports that are
as high as the top surface level of the turn base. Do not
rely solely on the vertical vise and/or horizontal vise
(both optional) to secure the workpiece. (Fig. 34)
Thin material tends to sag. Support workpiece over its
entire length to avoid blade pinch and possible KICK-
BACK.
Vertical vise (optional accessory) (Fig. 35)
The vertical vise can be installed in two positions on
either the left or right side of the guide fence or the holder
assembly (optional accessory). Insert the vise rod into
the hole in the guide fence or the holder assembly and
tighten the screw to secure the vise rod.
Position the vise arm according to the thickness and
shape of the workpiece and secure the vise arm by tight-
ening the screw. If the screw to secure the vise arm con-
tacts the guide fence, install the screw on the opposite
side of vise arm. Make sure that no part of the tool con-
tacts the vise when lowering the handle all the way. If
some part contacts the vise, re-position the vise.
Press the workpiece flat against the guide fence and the
turn base. Position the workpiece at the desired cutting
position and secure it firmly by tightening the vise knob.
CAUTION:
• The workpiece must be secured firmly against the turn
base and guide fence.
Horizontal vise (optional accessory) (Fig. 36)
The horizontal vise can be installed on either the left or
right side of the base. When performing 15° or greater
miter cuts, install the horizontal vise on the side opposite
the direction in which the turn base is to be turned. By
turning the vise knob counterclockwise, the screw is
released and the vise shaft can be moved rapidly in and
out. By turning the vise knob clockwise, the screw
remains secured. To grip the workpiece, turn the vise
knob gently clockwise until the projection reaches its top-
most position, then fasten securely. If the vise knob is
forced in or pulled out while being turned clockwise, the
projection may stop at an angle. In this case, turn the
vise knob back counterclockwise until the screw is
released, before turning again gently clockwise.
The maximum width of the workpiece which can be
secured by the horizontal vise is 130 mm.
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. 37)
When cutting long workpieces, use the holder-rod
assembly (optional accessory). It consists of two holder
assemblies and two rods 12. (Fig. 38)
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.
