We generally recommend the use of two-piece scoring saw
blades, which are brought to the required blade thickness by
placing spacers between them. The kerf of the scoring saw
blade should be approx. 0.1 mm wider than that of the main
saw blade, i.e. 0.05 mm to each side.
Caution:
Only Ø 125 mm scoring saw blades may be used.
Important:
If a saw blade with a diameter > 350 mm is used,
the scoring saw blade must be removed and the
safety catch
at the sawdust flap must be swivelled to the right.
