The present disclosure relates to a power tool (1) driven by an internal combustion engine and comprising a housing (9) and having a service access interface (11) for connecting to an internal control unit of the engine during service. The access interface (11) comprises a connector (21) and an access interface cable, connecting the connector (21) to the control unit. The housing comprises an opening (15), and a grommet (13) is provided configured to clamp the access interface cable or the connector (21). The grommet (13) is configured to be moved between an operating position and a service position. In the operating position, the grommet (13) is located in the opening (15), the access interface cable and connector (21) being fully enclosed in the housing (9), and in the service position, the grommet (13) is located in said notch, the access interface cable or connector (21) extending through the opening inside the grommet (13).

A power cutting tool includes at least one cutting strand and at least one guide unit configured to guide the cutting strand. The power cutting tool further includes at least one cutting strand contact guard unit which has at least one cutting strand contact guard element. The at least one cutting strand contact guard element is movably mounted on the guide unit and is configured to at least substantially prevent, in at least one operating position of the cutting strand contact guard element, contact between the cutting strand and a user of the power cutting tool.

A separating device for a machine tool includes at least one cutting strand and at least one guide unit configured to guide the cutting strand. The guide unit forms a closed system together with the cutting strand. The separating device further includes at least one cutting strand tensioning unit that is positioned on the guide unit, and that is configured to compensate for at least one of play and tolerance in the cutting strand.

A hand-held power tool includes an SDS tool receiver and a tool housing. The SDS tool receiver includes at least one vacuuming-off channel and is configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece. The tool housing includes at least one drive unit configured to drive the exchangeable insert tool.

A machine tool separating device, in particular a handheld machine separating device, includes at least one cutting strand and at least one guide unit. The cutting strand, viewed along a direction running at least substantially perpendicular to a cutting plane of the cutting strand, has a maximum dimension less than 4 mm.

A power cutting tool includes at least one cutting strand, and at least one guide unit that is configured to guide the cutting strand. The power cutting tool further includes at least one coding unit which has at least one coding element that is configured to encode at least one coupling interface of the guide unit.

Improved chain saws, components for chain saws, methods of making chain saws and components, and methods of using chain saws and components are disclosed. In some embodiments, a chain saw comprises a saw bar and a plurality of links, wherein a first link has a hook that engages a recess of a second link, thereby coupling the first link and the second link and allowing them to articulate without decoupling. The saw bar may have a rail, and the links may have grooves such that the links straddle and ride over the rail. The rail may have a projection and the grooves of the links may have notches accommodating the projection such that the projection prevents dislocation of the links. The links may have conical or pyramidal cutting teeth. The chain may be bidirectional. Robotic and automated operation of saws and other instruments are also disclosed.

A chainsaw apparatus has a body having a handle formed thereon or attached thereto, a motor, a saw blade coupled to the body so as to be extendable in transverse relationship to the longitudinal axis of the body, and a chain movably positioned on the saw blade. The motor is drivingly connected to the chain so as to cause the chain to move around the saw blade. The saw blade is adjustably coupled to the body so as to be movable between the position transverse to the longitudinal axis of the body to a position aligned with the longitudinal axis of the body. An angle adjustment mechanism is connected to the saw blade into the body. The angle adjustment mechanism is adapted to fix an angular position of the saw blade relative to the body.

Disclosed is a chainsaw capable of making it less likely that vibrations due to driving of an electric motor and a endless movement of a saw chain are transmitted to a worker, thereby enabling the worker to become less likely to be fatigued even in work using the chainsaw. The chainsaw includes an electric motor provided inside a body casing; a guide bar provided in a front portion of the body casing in such a manner as to protrude forwardly; a saw chain provided around an outer periphery of the guide bar in an endlessly movable manner, and configured to be endlessly moved along the outer periphery of the guide bar under driving of the electric motor; a handle section provided with respect to the body casing, and configured to be gripped by a worker; and an anti-vibration member interposed between the body casing and the handle section.

A power tool comprising a body (110) arranged to support a rotatable work tool (120), the body comprising a front handle (130) and a rear handle (140), wherein the front handle is arranged between the rotatable work tool and the rear handle, the power tool comprising a liquid dispensing system (151,152, 153, 155) for adding a controlled amount of liquid to the rotatable work tool, the liquid dispensing system comprising a valve (153) for adjusting a flow of liquid in the liquid dispensing system, wherein the valve comprises a control member (154) arranged on the body adjacent to the front handle such that the control member is operable by a hand gripping the front handle.
