Abstract:
1. A table saw, comprising: a latch hold mechanism; a swing arm pivotable about a pivot axis along a swing arm path between a first swing arm position and a second swing arm position so as to move a shaping member away from a work piece support surface; a latch movable between a first latch position whereat the swing arm is maintained at the first swing arm position and a second latch position whereat the swing arm is not maintained at the first swing arm position; an actuating device configured to transfer a force to the swing arm when the swing arm is maintained at the first swing arm position resulting in a bias on the latch in a direction toward the second latch position; at least one swing path guide extending adjacent to the swing arm path; at least one swing path tracker positioned to be in opposition to the at least one swing path guide along the pivot axis at a location radially outwardly of a bearing assembly supporting the swing arm such that a twist torque on the swing arm is opposed by the swing path guide; and a control system configured to control the actuating device to transfer a force to the swing arm when the swing arm is maintained at the first swing arm position sufficient to move the latch from the first latch position to the second latch position.
