Claim 0:
1. A cutting and dust or slurry collecting assembly, the assembly comprising:
a circular saw blade having a first side, a second side, a peripheral portion defining a working part of the saw blade, and a center of rotation;
a blade guard extending over a portion of the first side and the second side of the saw blade;
a splash guard operably coupled to the blade guard to act as a barrier between the circular saw blade and a user when the cutting and dust or slurry collecting assembly is in use; and
a cover device elongated in a direction perpendicular to the center of rotation, the cover device comprising:
a front end, a rear end, a top surface, a bottom surface, elongated sidewalls, and a longitudinal passage for the saw blade, the longitudinal passage extending through the cover device from the top surface to the bottom surface in a region extending from a position spaced apart from the rear end of the cover device to the front end of the cover device;
a discharge member disposed proximate the rear end of the cover device, the discharge member including an outlet connectable to a vacuum source; and
a connection member connecting the discharge member with at least one of the longitudinal passage or a cut created rearward of the longitudinal passage,

wherein the blade guard and the cover device are pivotably connected via a pivotable connection defining a pivot axis extending between and through the elongated sidewalls of the cover device such that the cover device and the blade guard are turnable in relation to each other so the saw blade is movable up and down the passage at least during cutting to change a radial distance of a portion of each opposing side of the blade that is proximate to the front end of the cover device measured relative to the center of rotation,
wherein a front arm distance between the pivotable connection of the cover device and the blade guard and the front end of the cover device is less than 2.0 times a radius of the saw blade thereby providing visibility of an edge of the saw blade,
wherein the cover device and the splash guard are alternately removably operably coupled to the blade guard such that the blade guard is engaged to a selected one of the cover device and the splash guard,
wherein the assembly further comprises a blade guard receiver that is configured to receive the blade guard,
wherein the splash guard is operably coupled to the blade guard via the blade guard receiver,
wherein the blade guard comprises a cover for covering at least a portion of a saw blade and a first locking member is disposed on an outer surface of the blade guard,
wherein the blade guard receiver comprises a housing which defines an opening and a second locking member on an inner surface of the housing,
wherein at least part of the blade guard, including the first locking member, is insertable into the opening, and
wherein said first and second locking members are arranged to cooperate with one another to lock the blade guard to the blade guard receiver when the blade guard is inserted into the blade guard receiver.
