SPREADER
At the back side of the blade there is a
metal plate mounted to the trunnion, called
spreader. The spreader prevents the kerf of
the work-piece from pinching the blade and
causing kick back.

ANTI-KICK BACK PAWLS
The anti-kick pawls are installed onto the
spreader. The anti-kick back pawls are
designed such that they allow the work-
piece to move only forward. During the
cutting operation if the work-piece moves
backward, the anti-kick back pawls will dig
into it and stop it.¸

BLADE GUARD
The clear polycarbonate guard allows the
operator to see the blade cutting the work-
piece during cutting operation. The guard
covers the blade on both sides and lifts up
as the work-piece is fed into the blade and
returns to the table surface when the work-
piece has passed through the blade. It
prevents the wood chips to fly and injure
the operator and it also prevents from
accidental contacts of objects with the
blade.

RIVING KNIFE
The riving knife is a metal plate which
prevents the newly cut work-piece from
pinching at the backside of the blade and
causing kickback. Basically the riving knife
does the same job as the spreader. But the
main difference is that the riving knife is
installed below the blade height while the
spreader is installed higher than the blade.
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 .
