A pivot assembly for mounting an operating member on a base member for pivotal movement about an axis at an optimum axial position comprising: a pivot shaft having an axis, a base member and an operating member having axially opposable first and second inner surfaces respectively, a first mounting apparatus for mounting one of the members at a fixed axial position on the pivot shaft, and a second mounting apparatus for mounting the other member on the pivot shaft for relative rotational movement, and for axial movement to a position where the first and second inner surfaces axially oppose each other with an axial space therebetween, and the other member is at the optimum axial position. The second mounting apparatus includes, a pair of compressible disk springs mounted to be in a biased condition when the other member is at the optimum axial position. The disk springs constantly tend to move the other member in one axial direction away from the optimum position. The second mounting apparatus also includes a stop which prevents movement of the other member relative to the pivot shaft in the one axial direction from the optimum position and maintains the disk springs in the biased condition thereby preventing movement of the other member from the optimum position due to wear induced axial dimensional changes.

A pivot assembly for use in mounting a cutting unit operating member that has a motor driven saw blade, on a base member for pivotal movement about an axis from a non-cutting position to a cutting position placing said blade at an optimum cutting position on said base comprising: a pivot shaft having an axis; a base member having a first inner surface means; a second inner surface means on said cutting unit operating member positionable in axially opposed relation to said first inner surface means; a first mounting means for mounting said base member at a fixed axial position on said pivot shaft; and a second mounting means mounting said cutting unit operating member on said pivot shaft for relative rotational movement only in an axially fixed plane which is normal to said pivot shaft axis at said optimum cutting position, and for axial adjustment of said operating member to locate said saw blade at the optimum position with an axial clearance between said first and second surface means sufficient to provide a clearance permitting said relative rotation when said opposed surfaces are in an unmachined condition of manufacture, said second mounting means including a biasing means interposed between said shaft and cutting unit operating member and adjustable to have an axial length which is variable within a range of short, intermediate and long axial lengths, said biasing means when adjusted to said intermediate axial length, causing said cutting unit operating member saw blade to locate at said optimum cutting position and exert a force tending to move said cutting unit and saw blade in one axial direction away from said optimum cutting position; and a removable cover mountable at a fixed position on said cutting unit operating member and having a stop portion for automatically adjusting said biasing means to said intermediate length when said blade cover is mounted in said fixed position so that axial wear between said pivot shaft and biasing means will manifest as a change in axial length of said biasing means from said intermediate length without axial deviation of said saw blade from said optimum position.
