The user of a power-driven bench saw must ensure that -
- the saw blade to be effectively guarded below the table; and
- the part of the saw blade above the table to be covered by a substantial guard that shall cover the saw at all times to at least the depth of the teeth and that shall automatically adjust itself to the thickness of and remain in contact with the material being cut: provided that where such a guard is impracticable, the top of the saw shall be covered by a strong manually-adjustable guard that shall be adjusted to extend downwards to a point as near as practicable to the cutting point of the saw: provided further that in the case of a breakdown saw, the guard shall effectively cover the top of the saw blade.
