摘要： A chainsaw having a drive motor. The chainsaw has a fixed part and a movable part. The guide bar is retained on the fixed part in a manner braced between the fixed part and a tensioning element. The movable part is shiftable in a longitudinal direction with respect to the fixed part in order to tension the saw chain with the tensioning element released. The chainsaw has a stop face and a tensioning face. At least one additional contact face that is firmly connected to the fixed part in the longitudinal direction and at least one additional contact face that is firmly connected to the movable part in the longitudinal direction are arranged between the stop face and the tensioning face. All the contact faces lie one after another in the flux of force from the tensioning element to the fixed part.

摘要： A handheld portable cutting apparatus having a cutter unit with a cutter unit longitudinal axis. In a central housing section of the cutting apparatus, a drive connection is arranged between an electric drive motor and the cutter unit, wherein a motor housing having a motor housing longitudinal axis extends from the central housing section. A handle extends from the central housing section in a handle longitudinal axis. The cutter unit includes a guide bar with a saw chain circulating thereon, wherein, in a side view onto the cutting apparatus, the point of intersection (S1) between the handle longitudinal axis and the motor housing longitudinal axis and also the point of intersection (S2) between the handle longitudinal axis and the cutter unit longitudinal axis lie in the central housing section.

摘要： A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around 5 which a chain (210) is rotatable. The guide bar (120) includes first and second side plates (400, 410), a core (420) and a tension indicator (240). The first and second side plates (400, 410) each face other and extend away from a housing (110) to a nose. The core (420) is disposed between the first side plate (400) and the second side plate (410). The tension indicator (240) is provided at the core (420) and is visible at at least one of the first side plate 10 (400) or the second side plate (410). The tension indicator (240) is configured to indicate a chain tension based on a position of the guide bar (120).

摘要： A chain saw unit has a sub-frame defining a plurality of mount locations and a plurality of operating components amongst which are at least: a) a battery operated motor; and b) a battery for operating the motor. The plurality of operating components is each operatively placed and maintained at one of the mount locations such that the sub-frame assembly and operatively placed operating components together make up at least part of a main operating unit to which a chain bar and cutting chain can be operatively assembled. The main operating unit has an exposed surface area. An outer housing assembly overlies the exposed surface area and defines an outermost exposed surface. The plurality of operating components are operatively maintained on the sub-frame assembly independently of the outer housing assembly.

摘要： A chain saw kit having a sub-frame assembly and a plurality of operating components, including at least a battery operated motor and battery. The sub-frame assembly is configured to define mount locations for the operating components so that the sub-frame assembly and operatively placed operating components make up at least a part of a main operating unit to which a chain bar and cutting chain can be assembled. A first outer housing assembly has at least a first outer housing part with a second outer housing assembly having at least a second outer housing part. The parts of the outer housing assemblies are interchangeably usable to allow selection of different overall size, shape, and/or appearance of chain saws based upon a common sub-frame assembly.

摘要： A vegetation cutting device comprises, a housing, and a motor located within the housing. The motor comprises a rotating output shaft for driving a pair of reciprocating blades. The vegetation cutting device also comprises a rotatable front handle being rotatably mounted on the housing and is adapted to rotate with respect to the housing. The rotatable front handle comprises, a first trigger wherein the motor is operable on actuation of the first trigger. A release button is mechanical cooperation with the rotatable front handle for actuating rotation of the front handle. The vegetation cutting device also comprises an interlock mechanism mechanically coupling the release button and the first trigger wherein actuation of the release button prevents actuation of the first trigger and actuation of the first trigger prevents actuation of the release button.
