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 above a workpiece support surface , comprising: removing a throat plate from a throat plate opening in the workpiece support surface ; 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 , characterized in further comprising: removing a reaction plug from an actuator housing ; removing a first actuator from the actuator housing ; installing a second actuator in the actuator housing ; and causing the second actuator to move the second latch from a first latch position whereat the drop arm assembly cannot be moved from the first drop arm assembly position to the second drop arm assembly position, to a second latch position whereat the drop arm assembly can be moved from the first drop arm assembly position to the second drop arm assembly position, by installing the reaction plug in the actuator housing . removing a throat plate from a throat plate opening in the workpiece support surface ; 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 , characterized in further comprising: removing a reaction plug from an actuator housing ; removing a first actuator from the actuator housing ; installing a second actuator in the actuator housing ; and causing the second actuator to move the second latch from a first latch position whereat the drop arm assembly cannot be moved from the first drop arm assembly position to the second drop arm assembly position, to a second latch position whereat the drop arm assembly can be moved from the first drop arm assembly position to the second drop arm assembly position, by installing the reaction plug in the actuator housing . removing a reaction plug from an actuator housing ; removing a first actuator from the actuator housing ; installing a second actuator in the actuator housing ; and causing the second actuator to move the second latch from a first latch position whereat the drop arm assembly cannot be moved from the first drop arm assembly position to the second drop arm assembly position, to a second latch position whereat the drop arm assembly can be moved from the first drop arm assembly position to the second drop arm assembly position, by installing the reaction plug in the actuator housing . <EOS>
