Horizontal vise (optional accessory) (Fig. 18)
The horizontal vise can be installed on either the left or
right side of the base. When performing 30° or greater
miter cuts, install the horizontal vise on the side opposite
the direction in which the turn table 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.
CAUTION:
• Grip the workpiece only when the projection is at the
topmost position. Failure to do so may result in insuffi-
cient securing of the workpiece. This could cause the
workpiece to be thrown, cause damage to the blade or
cause the loss of control, which can result in PER-
SONAL INJURY.
Holders and holder assembly (optional accessories)
(Fig. 19)
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
Fig. 19
.
Then tighten the screws firmly to secure the holders and
the holder assembly.
When cutting long workpieces, use the holder-rod
assembly (optional accessory). It consists of two holder
assemblies and two rods 12.
(Fig. 20)
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 turning the handle latch to the
released position.
• Make sure the blade is not contacting the workpiece,
etc. before the switch is turned on.
• 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. 21)
Secure the workpiece. 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. Cutting aluminum extrusion (Fig. 22)
When securing aluminum extrusions, use spacer blocks
or pieces of scrap as shown in
Fig. 22
to prevent defor-
mation of the aluminum. Use a cutting lubricant 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.
4. Wood facing (Fig. 23, 24 & 25)
Use of wood facing helps to assure splinter-free cuts in
workpieces. Attach a wood facing to the guide fence
using the holes in the guide fence.
See
Fig. 24
concerning the dimensions for a suggested
wood facing.
After changing the miter angle, cut the wood facing at
that selected angle. If there is a gap between the blade,
the wood facing and the workpiece, move the wood fac-
ing slightly in the direction of the arrow and cut it again.
CAUTION:
• Use straight wood of even thickness as the wood fac-
ing.
• Use screws to attach the wood facing to the guide
fence. The screws should be installed so that the screw
heads are below the surface of the wood facing.
• When the wood facing is attached, do not turn the turn
base with the handle lowered. The blade and/or the
wood facing will be damaged.
NOTE:
• When the wood facing is attached, the maximum cut-
ting capacities in width will be reduced by thickness of
the wood facing.
5. Cutting repetitive lengths (Fig. 26)
When cutting several pieces of stock to the same length,
ranging from 300 mm to 400 mm, use of the set plate
(optional accessory) will facilitate more efficient opera-
tion. Install the set plate on the holder (optional acces-
sory) as shown in
Fig. 26
.
Align the cutting line on your workpiece with either the
left or right side of the groove in the kerf board, and while
holding the workpiece from moving, move the set plate
flush against the end of the workpiece. Then secure the
set plate with the screw. When the set plate is not used,
loosen the screw and turn the set plate out of the way.
NOTE:
• Use of the holder-rod assembly (optional accessory)
allows cutting repetitive lengths up to 2,200 mm (7.2 ft.)
approximately.
