<p>A table-top saw comprises a base, frame, water pan and a table disposed with the frame for supporting a workpiece to be cut. The saw also includes a guide beam and a carriage operably connected to the guide beam by a fixing mechanism, wherein the carriage is capable of slidable movement along the guide beam. A cutter-motor unit, including a saw and motor, is secured to the carriage whereby the cutter-motor unit is slidable along the guide beam. The fixing mechanism includes a trig block for locking the carriage and the cutter-motor unit at a selected position on the guide beam. The fixing mechanism is movable between a released position wherein a clearance is defined between a lower surface of the guide beam and the trig device to allow for movement along the guide beam, and a locked position wherein the trig device engages the lower surface of the guide beam. The fixing mechanism further includes a rotatable rod that extends through a slot in the trig block and a hole in the carriage, wherein an upper end of the rod includes an eccentric wheel and a lower end of the rod includes a handle that is actuated by an operator to move the fixing mechanism between the released and locked positions.</p> |
