3.3.2 Riving knives

The correct setting of the riving knife is of great im-
portance for safety. The gap between the riving
knife and the toothed wheel of the saw blade may
not be more than 8 mm in the area of the cutting
height. The sensible gap in practice is around 5
mm. Use of the positively guided Altendorf riving
knife automatically ensures with this gap that the
height adjustment of the riving knife matches the tip
appr. 2 mm below the uppermost tooth (see illustra-
tion).
Adjustment
Before adjusting the riving knife you must check
whether its size and thickness match the saw blade
being used. The series versions of the machine are
supplied with the following riving knives: (range of
diameters and thickness are stamped on the lower
end of the knife in each case)..
250/2,5 for saw blade diameter of 250 mm, with a
body thickness up to maximum 2,5 mm
315/2.8 for saw blade diameter of 300 bis 315 mm,
with a body thickness up to maximum 2.8 mm.
300-350/2.8 for saw blade diameter of 300 to 350
mm, with a body thickness up to maximum 2.8 mm..
400-450/3.2 for saw blade diameter of 400 mm,
with a body thickness up to maximum 3.2 mm.
The thicknesses of the riving knife are selected so
that they match the commercially available saw
blade thicknesses in the relevant diameter range.
