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.20
Horizontal vise (optional accessory)
Fig.21
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.
Vertical vise (optional accessory)
Fig.22
Fig.23
The vertical vise can be installed in the position on either
the left or right side of the guide fence. Insert the vise rod
into the hole in the guide fence 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 with the vise during all
operations.
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.24
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.25
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.
