Abstract: A blade change mechanism configured to attach a blade to a transmission rod of a power tool, the blade change mechanism including a support body, a blade retention structure, and a component. The blade retention structure is coupled to the support body and includes a blade retention component movable to hold the blade in a locked state in response to engagement of the blade with the blade change mechanism on insertion of the blade. The component is movable to vary the blade retention component to hold the blade in the locked state. The component is further movable to vary the blade retention component to an unlocked state in which the blade retention structure is disengaged from the blade. The blade retention structure is held in the unlocked state absent the blade being fully inserted into the blade change mechanism.

Abstract: A heater including a housing, a heater unit, a control interface, and a fan unit. The housing includes a base. The heater unit is supported on the base and includes an ignitor mechanism and a heater element having an external surface configured to emit heat. The control interface is supported on an exterior of the housing and includes an actuator operable by a user. The fan unit is coupled to the base or the heater unit and is positioned to induce an airflow through the heater unit within the heater element to heat the airflow. The fan unit includes a fan shroud having an air outlet to direct the heated airflow radially outward.
