Function of the riving knife
-
Always use the saw blade that is suitable for the riving knife.
The riving knife is only effective if the body
of the saw blade is thinner than the riving knife and the tooth width is greater than the thickness of the riving
knife.
-
Adjust the riving knife as described in these operating instructions.
Incorrect spacing, position and
alignment can be the reason that the riving knife can not prevent kickback efficiently.
-
Always use the riving knife, with the exception of "plunge cuts".
Mount the riving knife back on after
the plunge cut. The riving knife interferes with plunge cuts and can cause kickback. This section only applies
to hand-held circular saws without a pivoting riving knife (known as MAFELL flip knife). The flip knife retracts
into the machine during a plunge cut.
-
To be effective, the riving knife must be in the kerf.
In short cuts, the riving knife is ineffective for
preventing kickback.
-
Never operate the saw with a bent riving knife.
Even a minor malfunction can slow down the closing of
the guard.
