Claim 10:
11. A cover device for a saw blade, 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 to pass through, the longitudinal passage extending through the cover device from the top surface to the bottom surface in a region between the front and rear ends of the cover device,
wherein the rear end of the cover device is configured to be pivotably connected via a pivotable connection defining a pivot axis extending between and through the elongated sidewalls of the cover device to a rear end of a blade guard of the saw blade such that the cover device and the blade guard are turnable in relation to each other so that the saw blade is movable up and down the longitudinal passage such that a portion of the longitudinal passage at the front end of the cover device is proximate to a changing radial distance of each opposing side of the saw blade measured relative to the center of rotation at least during a cutting operation,
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,
wherein the cover device comprises a blade guard receiver that is configured to receive the blade guard,
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 second locking member and a housing which defines an opening,
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.
