Abstract: A backpack power tool has drive motor and blower mounted on a backpack frame. The bottom plate of the backpack frame has a passage for working air sucked in by the blower. Ribs on the bottom side of the bottom plate have end faces forming a contact surface for leaves aspirated in blower operation against the bottom plate. The bottom plate has intake openings positioned between the end faces of the ribs in the contact surface and fluidically connected to the passage. Working air is sucked in through the intake openings and the passage. The bottom plate has an intake surface that is the sum of surfaces of all intake openings and of all end faces of ribs with a width of less than 10 mm positioned between the intake openings. The intake surface amounts to at least 50% of the surface of the bottom side of the bottom plate.

Abstract: A manually guided blower having a housing in which is disposed a drive motor that rotatingly drives an impeller. The impeller draws in an air stream via an intake opening and conveys the air stream through a discharge opening of the housing. The blower has at least one attachment that can be detachably connected to the housing in the region of one of the openings. The blower has at least one switch that is actuated when the attachment is secured to the opening, whereby the drive motor is in a ready-to-operate state only when the switch is actuated.

Abstract: The invention is directed to a cutter blade support for a pair of knives of a hedge trimmer. The cutter blade support includes first and second bars conjointly defining a space therebetween. First and second cutter blades are arranged in the space and define respective sets of apertures formed therein. The first bar has openings formed therein and a plurality of threaded bolts are held in the second bar. The threaded bolts extend through the respective sets of apertures and have respective end portions extending through the openings in the first bar. Attachment nuts are disposed on the first bar and threadably engage corresponding ones of the end portions. The threaded bolts are pressed into the second bar so as to be tightly held therein and so as to be nonrotatable with respect thereto.
