Securing workpiece
WARNING:
It is extremely important to always secure the
•
workpiece properly and tightly with the vise. Failure
to do so can cause the tool to be damaged and/or
the workpiece to be destroyed. PERSONAL
INJURY MAY ALSO RESULT. Also, after a cutting
operation, DO NOT raise the blade until the blade
has come to a complete stop.
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 to secure the workpiece.
Thin material tends to sag. Support workpiece over
its entire length to avoid blade pinch and possible
KICKBACK.
Fig.17
Horizontal vise (Accessory)
Fig.18
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.
CAUTION:
Grip the workpiece only when the projection is at
•
the topmost position. Failure to do so may result in
insufficient 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 PERSONAL 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
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.20
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 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 with the vise. 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 the figure to
prevent deformation 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
•
extrusions. Thick aluminum extrusions may come
loose during operation and round aluminum
extrusions cannot be secured firmly with this tool.
