A garden and/or forestry system has a hand-held gardening and/or forestry processing apparatus, and an assistance device, which is formed separately from the gardening and/or forestry processing apparatus and which is designed to support a user in operation of the gardening and/or forestry processing apparatus. The assistance device has a user interface, by which the assistance device is controllable by user inputs. The hand-held gardening and/or forestry processing apparatus has a user-actuable operator control element for user inputs to the user interface.

Garden and/or forestry system

A system assists during execution of a sequence of cuttings in a tree, wherein, during a cutting sequence, a first cut in the tree is followed by a second cut in the tree At least a part of an ideal course of the second cut depends on at least a part of a course of the first cut. An identification device identifies at least the part of the course of the first cut in the tree. A precalculation device precalculates at least the part of the ideal course of the second cut in the tree based on the identified part of the course of the first cut. An output device outputs cutting information for executing the second cut based on the precalculated part of the ideal course of the second cut.

A method obtains a pollution condition of at least one component of a gardening and/or forestry apparatus. The method includes the steps of: obtaining at least one pollution parameter which describes at least one source of pollution prevalent during an operation of the gardening and/or forestry apparatus; obtaining the pollution condition of the component based on the obtained pollution parameter; and outputting and/or transmitting information based on the obtained pollution condition.

A power saw system has a power saw with housing; guide bar; and saw chain driven about the guide bar by an electric drive motor. A battery is arranged outside of the housing. A power cable is connected with its first end through an electrical connection to the battery and with the second end to the drive motor to supply the drive motor with power. An elastic securing element is connected by a fastening element to the housing. A connecting device connects by a mechanical connection the securing element to an operator of the power saw. The connecting device has an overload protection separating the mechanical connection between securing element and operator when a maximum pulling force is surpassed. Securing element and power cable form a cable assembly. A pull-out force for separating the electrical connection is smaller than the maximum pulling force.

Power saw system and cable assembly for a power saw

The invention relates to a work device with a guide rail () on which a chain () is driven in a circulating manner. The work device has a clamping device () for the chain (). The clamping device () has a clamping element () which acts on en the guide rail () in the direction () of the longitudinal central axis () of the guide rail (). The clamping device () has a rotatably mounted adjusting element () which is connected to the clamping element () via a threaded connection (). A rotation of the adjusting element () about its rotational axis () causes a movement of the clamping element () in the direction () of the longitudinal central axis () of the guide rail (). The outer circumference of the adjusting element () has a threaded portion () with at least one turn (), said threaded portion being provided for engaging with at least one threaded portion () of the clamping element (). The adjusting element () has an actuating contour () so that a user can rotate the adjusting element (), said actuating contour comprising at least one depression. The largest spacing (b) between the threaded portion () of the adjusting element () and the rotational axis () is at least as large as the largest spacing (a) between the actuating contour () and the rotational axis ().

Work device

A handheld work apparatus has a drive motor which drives a tool of the work apparatus. A lubricating arrangement is provided for the tool. The lubricating arrangement includes a lubricant piece that is solid at 20&#xb0; C. The work apparatus has a melting chamber into which the lubricant piece projects and which is connected to the tool via at least one lubricant channel. The melting chamber is delimited at least partially by a heat conducting element which is heated during operation of the work apparatus.
