General note:
Setup and adjustment work may only be carried out after the

7.1 Saw blade selection

The sawblade has to meet the technical specification.
Choose a suitable sawblade, according to the cutting operation
and according to the material to be cut.
For a high rip cut:
- use a wide sawblade, coarse teethed
(e.g. 20mm, 3 T/")
For a narrow curved cut:
- use a narrow sawblade
(e.g. 3mm, 14 T/").

Pitch:
The pitch should not be smaller than necessary, as the feed speed
is reduced if there are too many teeth working on the workpiece
simultaneously, which causes the saw blade to wear more quickly.
Ideally, 3 to 12 teeth should be in action at the same time (Fig 27).
The following table shows recommended saw blade pitch in
relation to workpiece thickness (Fig 28).
Tooth Shape:
The tooth shape effects the chip capacity and the feed rate. The
following table shows common tooth shapes (Fig 29):
