Lightly hit the tip of the point from above and below, and
hit its sides from right and left.
Confirm that rubber pin lock (3) and lock pin (2) are set as

The life of the teeth can be lengthened and the frequency of
their replacement can be reduced by turning them upside
down so that they will wear evenly.
Replace the rubber pin lock and locking pin at the same time
as replacing the teeth. This makes it possible to prevent the
teeth from falling out.
