(1) You must guard miter saws with an upper hood that completely encloses the upper half of the blade.

(2) You must provide a method to protect employees from contacting the blade underneath the table while in its recommended carrying position.

(3) You must guard the lower blade:

(a) By making sure the teeth are guarded at least three-quarters of an inch beyond the root of the teeth, toward the center of the blade, except for a maximum forty-five degree exposure of quadrant C when in the full retract position. See Illustration 480-1, Miter Saw Guarding.
