IMPORTANT: 1. Use a notched "push-stick" (Fig. 33
and see drawing in Fig. 41) to feed the
wood through the blade and hold it
down at the same time, thereby
keeping your hands at a safe distance
from the blade.
2. Before switching on the motor for
ripping, make sure the riving knife and
anti-kickback fingers are correctly
positioned for safe operation.
3. After the ripping operation has been
completed, you may find that sawdust
has collected in the arm tracks and on
the yoke assembly's bearings - to
clean, follow the instructions on page
11.
(i) Set the machine in the bevel cross-cut position as
above,
(ii) Then rotate the yoke assembly into the rip position as
described for ripping above.
(iii) Using the rip lock locate the yoke assembly on the
arm for the correct ripping width.
(iv) Angle the anti-kickback fingers so that they will be
flat on the material being cut (Fig. 34) and lower the
riving knife.
(v) Then proceed with the cut as for ripping.
The compound mitre cut is a combination of a bevel and a
mitre cut.
(i) Set the machine in the bevel position.
(ii) Release the arm clamp handle and the mitre latch.
(iii) Swing the arm into the required mitre position then
relock the arm clamp handle.
(iv) • Draw the saw across the material as for mitre cuts.
Note: You may find it advisable to clamp the material to the
fence to hold it firmly while cutting.
By tilting the motor with the blade rotating in the work, you
can produce many shapes not possible with conventional
sawing systems. In Fig. 36, a shallow concave profile is
being cut. Having tilted the blade and rotated the motor
yoke beneath the arm, the material is fed through as for
ripping. By changing the angle combinations, an infinite
variety of widths and pitches of channel can be made.
The optional Powershop Handbook gives further
examples of how this feature of your machine can be
utilised.
By releasing the bevel clamp and disengaging the bevel
latch with an appropriately shaped piece of wood, the
rotating blade can then be tilted through an arc to cut a
shallow hollow in the surface of a piece of wood clamped
to the table. The blade is then returned to the 0° upright
position and the elevating handle wound down half a turn
before tilting the rotating blade again and repeating this
procedure until the required depth has been reached.
It is necessary to hold both the blade guard and the other
end of the motor while cutting progresses to avoid undue
flexing and pressure being placed on the blade guard and
its mounting.
