MITRE CUTTING:
The circular saw is especially suitable for cutting mitres in
flat frame members (see Sketch). The mitre fence, against
which the wood is held, must first be set to the re9uired
angle.
If many mitre cuts are to be made, a deflector should be fitted.
RABBETING ON THE CIRCULAR-SAW:
For rabbeting, the ripping fence should be fitted with an
extension to its bearing surface (Sketch A).
A slow feed must be employed, since the saw dust cannot be
thrown out over the top of the component. Sketch l O shows
the operations involved in rabbeting on the circular saw.
GROOVING ON THE CIRCULAR SAW:
��,......_st
cu-t ---,
The circular saw can be used as a wobble saw if the saw
blade is canted on the spindle by means of the two wobble
saw washers.
FITTING THE CIRCULAR SAW BLADE WITH WOBBLE
ATTACHMENTS:
1. Remove the table insert M 6.20-01 by unscrewing the
two countersunk screws DIN 63 M 4 x 12 (Photo KS 8
andKS9).
2. Remove the saw arm and the circular saw cover plate
(see "Fitting and removing circular-saw blade").
3. The saw blade and the backing washer on the spindle
are removed.

4. The two wobble-saw washers are placed on the
spindle in place of the backing washer.

5. Fit the saw blade, the clamping washer, the
spherical washer, and the hexagon nut, which
should be tightened up only hand-tight
(Sketch 11 A)
6. Now adjust the relative positions of the two
tapered wobble-saw washers until the saw blade
is at the desired angle.
The left-hand ii lustration
in Sketch 11 shows the
blade set to the minimum
angle for wobble-saw work,
while the right-hand
i I lustration shows it at the
maximum angle. If the

is utilised a groove width
