CA 2482119

The present invention relates to a sawing direction positioning system for a bench saw comprising a fight-emitting unit for emitting a planar light beam installed at a protection plate of said bench saw, said light-emitting unit being connected with a power supply via a lead and positioned to emit forward and downward said planar light beam so that said planar light beam coincides exactly with the central plane of a circular saw blade mounted on said bench saw. The projection line of the planar light beam on a wood to be sawed is a very fine straight line which marks the sawing direction for the circular saw blade. During sawing, the projection line of the planar light beam always projects on the wood to be sawed and is not obstructed by the sawdust. The operator may have a good visual field and push the wood to be sawed forwardly along the right straight line to ensure that the sawing direction is correct or keeps in line with the drawn straight line, thereby preventing the kerf from offsetting and reducing the rejected products.
