Abstract: A backpack sprayer has a carrying arrangement, on which a container for spraying agent is arranged. The container has a filling opening which can be closed by way of a lid. The carrying arrangement has a set-down position, in which the carrying arrangement is set down on a planar, horizontal set-down surface. The spraying agent region of the container is the region which is provided for spraying agent and extends as far as a maximum permissible filling height (max). The spraying agent region has a greatest horizontal inner cross-sectional area (A) in the set-down position. In order to allow simple filling of spraying agent and simple cleaning of the container, it is provided that the container can be opened at the filling opening over at least 60% of its greatest inner cross-sectional area (A).

Abstract: A vacuum device has a motor-driven blower wheel with suction side and with pressure side with pressure channel and blow-out opening. An intake pipe at the suction side has an intake opening and a discharge opening at opposed ends. The intake pipe conveys a suction airflow entraining first and second collected materials. Through the discharge opening the first collected material is discharged from the intake pipe. A blower inlet opening is formed in a wall of the intake pipe. Blower inlet opening, blower wheel, and pressure channel are configured such that second collected material passes through blower inlet opening and blower wheel into the pressure channel for discharge through blow-out opening. The blower inlet opening, in longitudinal direction of the intake pipe, is positioned between discharge opening and intake opening at a first spacing to the intake opening and at a second spacing to the discharge opening.

The tank closure (2) includes an outer part (6) and an inner part (8) which are limitedly movable toward one another in the axial direction of the tank stub (1). The inner part (8) does not rotate but is guided axially displaceably in the tank stub (1) and the outer part (6) is rotatable relative to the inner part (8) on the tank stub (1) so as to be fix-tightly screwable thereon. A spring (26) is provided between the outer part (6) and the inner part (8). The spring biases the inner part (8) against the sealing surface (16) on the tank stub (1).

Abstract: A protective shield for a trimmer having a cutting head that is rotatable about an axis of rotation and supports a cutting thread that rotates about an axis of rotation with the cutting head and determines a cutting circle, covers at least partially the cutting circle. The protective cover has a base member and a cutting-to-length blade arranged on the base member so as to be positioned circumferentially relative to a cutting circle of the rotating cutting thread. The cutting-to-length blade has a cutting edge that, relative to the axis of rotation of the rotating cutting thread, is arranged in an axially displaced position displaced in an axial direction relative to the cutting circle. A device for axially deflecting the rotating cutting thread out of the cutting circle to the cutting edge is provided.
