Cutting aluminum extrusion
► Fig.52: 1. Vise 2. Spacer block 3. Guide fence
4. Aluminum extrusion 5. Spacer block
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.
Never attempt to cut thick or
WARNING:
round aluminum extrusions. Thick or round alumi-
num extrusions can be difficult to secure and the work
may loosen during the cutting operation which may
result in loss of control and serious personal injury.
Wood facing
Use screws to attach the wood
WARNING:
facing to the guide fence. The screws should be
installed so that the screw heads are below the
surface of the wood facing so that they will not
interfere with the positioning of the material being
cut. Misalignment of the material being cut can case
unexpected movement during the cutting operation
which may result in a loss of control and serious
personal injury.
Use straight wood of even thick-
CAUTION:
ness for the wood facing.
In order to completely cut through
CAUTION:
workpieces with a height of 107 mm to 120 mm, a
wood facing should be used on the guide fence.
The wood facing will space the workpiece away from
the fence allowing the blade to complete a deeper cut.
When the wood facing is attached, do
NOTICE:
not turn the turn base with the handle lowered.
The blade and/or the wood facing will be damaged.
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 and 6 mm screws.
See the figure concerning the dimensions for a sug-
gested wood facing.

Groove cutting

WARNING:
type of cut by using a wider type blade or dado
blade. Attempting to make a groove cut with a wider
blade or dado blade could lead to unexpected cutting
results and kickback which may result in serious
personal injury.
WARNING:
to the original position when performing other
than groove cutting. Attempting to make cuts with
the stopper arm in the incorrect position could lead to
unexpected cutting results and kickback which may
result in serious personal injury.
For a dado type cut, perform as follows:
1. Adjust the lower limit position of the blade using
the adjusting screw and the stopper arm to limit the cut-
ting depth of the blade. Refer to "Stopper arm" section
described on previously.
2. After adjusting the lower limit position of the blade,
cut parallel grooves across the width of the workpiece
using a slide (push) cut.
► Fig.54: 1. Cut grooves with blade
3.
Remove the workpiece material between the
grooves with a chisel.
Special Max Width Cutting
Capacities Technique
The maximum width cutting capacity of this tool can be
achieved by following the steps below:
For the maximum cutting width of this tool refer to the
SPECIFICATIONS under "Cutting capacities for special
cuttings".
1.
Set the tool at 0° or 45° miter angle and make sure
that the turn base is locked. (Refer to the section titled
"Adjusting the miter angle".)
2.
Remove both right and left upper fences temporar-
ily and set aside.
3.
Cut a platform to the dimensions indicated in the
figure using a 38 mm thick, flat stock material such as
wood, plywood or particle board.
► Fig.55: 1. 0° Miter angle: Over 450 mm 2. 45° Miter
angle: Over 325 mm 3. 38 mm 4. Over
760 mm
WARNING:
platform. Stock that is not flat may move during the
cutting operation which may result in kickback and
serious personal injury.
NOTE: The maximum cutting capacity in height will
be reduced by the same amount as the platform
thickness.
