Figure-25 Riving knife
The riving knife is installed when doing non-
through cuts using a standard table saw
blade and for the cutting operations when
the blade does not cut all the way through
thickness of the work-piece.
Height Difference:
The riving knife should be installed with
1mm to 5mm height difference with the
blade height. It is recommended to keep
3mm to 8mm distance between the blade
(from the carbide tip) and the riving knife.
WORK-PIECE INSPECTION
Before cutting the work-piece, make sure to
inspect it for nails, staples, small pieces of
stone or metal and any other foreign object
which is dangerous to come in contact with
the blade.
If the wood contains any of these objects
and it comes in contact with the blade, the
object might fly and hit the operator or
damage the blade. For a safe cutting
operation, always inspect your work-piece
carefully before cutting and wear eye
protection.
Some woods with excessive twisting or
wrapping are un-stable while cutting. This
situation can be dangerous, because during
operation the work-piece can move un-
expectedly which can either damage the
blade or hurt the operator.
If the wood is slightly cupped, make sure
the cupped face of the wood is held against
the table or the fence. If the bowed side of
the work-piece is held against the table or
the fence, there will be a great possibility
that the work-piece move unexpectedly
while cutting, and cause kickback or injury
to the operator.
Some stock with large knots can damage
the blade and wet stock will give a poor
result.
WARNING
DO NOT use the riving knife with dado
blades. If used, the riving knife will be
higher than the dado blade and the work-
piece will hit the riving knife.
WARNING
The information above is just a guideline
for you to understand how to cut a work-
piece with slight cupping. If you are not
sure and do not have any experience in
cutting cupped stock, do not cut it.
Failure to follow these instructions might
bring personal injuries to the operator or
serious damage to the blade.
