Vertical vise (optional accessory)
Fig.37
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
tightening the screw. If the screw to secure the vise arm
contacts the guide fence, install the screw on the
opposite side of vise arm. Make sure that no part of the
tool contacts 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.38
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 topmost 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)
Fig.39
The holders and the holder assembly can be installed
on either side as a convenient means of supporting
workpieces horizontally. Install them as shown in the
figure. 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.40
CAUTION:
Always support long workpieces level with the top
•
surface 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
•
lowered 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.41
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.42
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
