An device for manually unlocking a holding mechanism to which a load is applied is disclosed. The device has an operating element which is to be operated manually for unlocking the holding mechanism via an operating force that increases as the load increases, a conversion mechanism which includes a force transfer element coupled to the operating element, and a trigger coupled to the force transfer element. In order to unlock the holding mechanism the trigger is movable by the operating force transferred by the force transfer element to the trigger from a locked position in which the trigger is operatively decoupled from an unlocking component into an unlocked position in which the trigger is in contact with the unlocking component and unlocks said holding mechanism. The conversion mechanism includes an elastically deformable force limiter via which the force transfer element is coupled to the trigger.

A dust collection system for a circular saw having a saw housing and a motor configured to rotationally drive a saw blade includes a dust collecting member and a guide mechanism. The dust collecting member includes a body having a first end in which a dust collection opening is defined and a second end operably connectable to an airflow generation device. The guide mechanism is configured to support the dust collecting member on the saw housing such that the dust collection opening remains adjacent to an outer edge of the saw blade in response to one of the dust collecting member and the guide mechanism contacting the workpiece to move the dust collecting member.
