Self-Adjusting |

|
The openings of self-adjusting guards are determined by the movement of the
stock. As the operator moves the stock into the danger area, the guard is pushed away,
providing an opening which is only large enough to admit the stock. After the stock is
removed, the guard returns to the rest position. This guard protects the operator by
placing a barrier between the danger area and the operator. The guards may be constructed
of plastic, metal, or other substantial material. Self-adjusting guards offer different
degrees of protection. The figure to the left shows a radial arm saw with a self-adjusting guard. As the blade is pulled across the stock, the guard moves up, staying in contact with the stock. |
