A surgical stapling apparatus having an end effector capable of performing a surgical procedure. The surgical stapling apparatus may include a driving pawl that interfaces with a manually actuatable handle. The driving pawl may have a pawl body with a driving tooth thereon that is configured to interact with an actuation shaft such that, as the manually actuatable handle is actuated, the driving tooth interacts with the actuation shaft to cause the actuation shaft to apply the actuation motions to an elongated body operably coupled to the end effector. When the end effector experiences a firing load that exceeds a predetermined magnitude of firing load, the driving tooth moves relative to the pawl body to disengage from the actuation shaft to prevent further transfer of the actuation motions to the elongated body even though the manually actuatable handle continues to be actuated.
