An implement comprising a first handle, on which are disposed control elements for the implement. A versatile use of an implement to which is secured a first handle can be provided if the first handle is secured to a tubular section of the implement via a clamp, whereby a handle is detachably mounted on the clamp and the clamp is mounted on the tubular section.

Implement

A portable handheld work apparatus has a housing () which has at least one intake opening (). A drive motor () is mounted in the housing () and this drive motor drives a fan wheel (). The fan wheel () inducts a cooling airflow () into the housing () through the intake opening (). The cooling airflow () is moved to the drive motor () by the fan wheel (). A driven drive element rotating about the rotational axis () is provided. To prevent a wrapping of long-fibrous material onto the rotating drive element, it is provided that the drive element is surrounded at least partially by a wrap protector () fixed to the housing. The wrap protector has a radially outwardly directed flange () referred to the rotational axis (). The flange () is at a distance (a) to an adjacent, rotatably driven component.

Portable handheld work apparatus

A manually guided suction apparatus for suctioning up material via a suction air stream, comprising a suction fan having a fan housing surrounding a fan wheel and provided with an intake opening. A centrifugal separator is disposed upstream of the intake opening and produces a curved path of the suction air stream. The centrifugal separator has a curved peripheral wall in which is disposed a removal opening for material that is to be sucked up. The intake opening is disposed approximately in a central portion of the centrifugal separator.

Manually guided suction apparatus

A manually guided suction apparatus for suctioning up material via a suction air stream, comprising a suction fan having a fan housing surrounding a fan wheel and provided with an intake opening. A removal opening for sucked up material is disposed upstream of the intake opening in an intake channel that guides the suction air stream toward the suction fan. The removal opening empties into a collection bag, and the suction air stream in the intake channel is guided past the removal opening. An endless tube folded up to form a supply portion is stored in a storage chamber. A container portion of the endless tube forms the collection bag. A weight support for the collection bag prevents the supply portion from being pulled out of the storage chamber.

An implement comprising a first handle, on which are disposed control elements for the implement, and a second handle. The first handle is adjustable between a first operating position for a two-handed operation in which the implement is adapted to be guided by both the first handle and the second handle, and a second operating position for one-handed operation in which the implement is adapted to be guided by the first handle.

Implement having adjustable handle

A blower apparatus has a blower housing having a blower intake. A motor-driven blower is arranged in the blower housing and takes in air in a flow direction through the blower intake into the blower housing. A device for mechanical clearing of the blower intake is arranged at the blower intake. The mechanical clearing device is driven in rotation during operation of the blower apparatus.

Blower apparatus

A vacuum arrangement has a vacuum pipe having a vacuum opening facing a ground surface and adapted to pick up from the ground surface a material to be collected. The vacuum pipe conveys the material to be collected into a collecting container connected to the vacuum pipe. The vacuum pipe has a working area located within the area of the vacuum opening. At least one blower nozzle having a blower air exit is arranged such that a blower air flow exiting from the blower air exit is directed onto the ground surface into the working area. The blower air exit and the vacuum opening are positioned at a spacing relative to one another.

Vacuum arrangement for a ground area

An apparatus comprising a blower fan, a motor for driving the blower fan, a blower tube for conveying an air stream from the blower fan, and a potential compensation device that is electrically connected with the motor. The potential compensation device includes a charge compensation element having a free end that projects in an exposed manner into the air stream.
