Problems solved by technology

Another disadvantage of this type of safety device is that the shaping device must have teeth
Additionally, if spare blades and brake members are not on hand, the user must go to storage to obtain replacements
Therefore, this type of security system can be expensive and inconvenient

Abstract

A method of resetting a drop arm assembly in a power tool assembly from a first drop arm assembly position whereat a portion of a shaping device mounted on the drop arm assembly does not extend abovea workpiece support surface, includes removing a throat plate from a throat plate opening, moving at least a portion of a blade wrench downwardly through the throat plate opening, operably coupling the blade wrench with an arbor shaft of a drop arm assembly, releasing a first latch from engagement with a drop arm frame of the drop arm assembly after removing the throat plate, pulling the coupled blade wrench in an upwardly direction to a second drop arm assembly position whereat the portion of the shaping device extends above a workpiece support surface, and latching the drop arm assembly at the second drop arm assembly position with a second latch.

Description

[0001] This application claims U.S. Provisional Application (Serial No. 62 / 132,004) filed March 12, 2015, entitled "TABLE SAW WITH DROPPING BLADE" and filed March 12, 2015, entitled "SYSTEM AND METHODFOR CONTROL OF A DROP ARM IN A TABLE SAW" (Serial No. 62 / 131,977), the disclosures of each of which are incorporated herein by reference in their entirety. technical field [0002] The present disclosure relates to power tools, and more particularly to power tools having bare forming devices. Background technique [0003] Many power tools have been produced to assist in forming a workpiece into a desired shape. A table saw is one such power tool. A wide variety of table saws are available for a variety of purposes. Some table saws, such as cabinet table saws, are heavy and relatively immobile. Other table saws (sometimes called job site table saws) are relatively light. Therefore, the work site table saw is portable so that the worker can position the table saw at the work s...
