A power working machine comprises a working portion, a driving portion, a main body portion, and a blowing portion. The working portion is configured to act on a work object. The driving portion is configured to drive the working portion. The main body portion includes a bottom surface portion, an intake port, and an exhaust port, and is configured to form a storage space for storing the driving portion and an airflow path leading from the intake port to the exhaust port through the storage space. The blowing portion is configured to generate an airflow in the airflow path toward the exhaust port. The intake port is configured to open in a direction having a vertical downward component in a first state in which the power working machine is placed with the bottom surface portion facing a horizontal surface.

A simple configuration is provided to facilitate removal of a battery. An electric working machine comprises an electric working portion and a main body portion. The electric working portion is configured to operate by electric power supplied from a battery. The main body portion includes a battery holding portion having a holding space for inserting the battery in an insertion direction and holding the battery. The battery holding portion includes a plurality of openings including a first opening through which the battery passes when inserted and a second opening provided at a position that is separated from a front end of the battery held in the holding space in the insertion direction.

A hand-guided treatment device has a motor housing which includes a basic housing body that extends at least on a first housing side, and a remaining housing body, which is connected to the basic housing body and, together with the basic housing body, encloses a housing interior. A drive motor in the housing interior is held on the basic housing body. The basic housing body has a tool-holding device for holding a tool driven by the drive motor. The basic housing body forms a rigid motor- and tool-supporting structure which extends at least on the first housing side and on an adjoining second housing side, forming an L shape, wherein the remaining housing body forms a non-rigid remaining housing structure.

Saw systems are provided. A saw system includes a body and one or more interchangeable saw cartridges. The body includes a prime mover and a transmission element. Activation of the prime mover drives the transmission element. Each of the one or more interchangeable saw cartridges includes a saw blade and is interchangeably connectable to the body. The connection of one of the one or more interchangeable saw cartridges to the body causes the saw blade of the one of the one or more interchangeable saw cartridges to be drivable by the transmission element.

An electric working machine may include: a support rod constituted of metal; a tool disposed at a front end of the support rod; a motor configured to drive the tool; a control unit disposed at a rear end of the support rod and configured to control the motor; and a heat transfer structure configured to transfer heat from the control unit to the support rod.

A chainsaw (electric working tool) includes a body case; a cutting part (working implement); and a motor, wherein the motor is mounted in a cooling route in the body case; an intake communicating with the cooling route is opened on the body case; an air filter is housed between the intake and the cooling route; the body case has a filter insertion/extraction hole through which the air filter can be inserted and removed; the intake is opened on the outer surface of the body case; and the filter insertion/extraction hole is arranged at a portion other than that of the intake so that the motor can be efficiently cooled, dust hardly enters the cooling route, and maintenance can be easily performed.

A chainsaw limb gripping attachment system comprising a chainsaw comprising a motor with a handle configured for holding by a user, and a blade configured to extend away from the motor, the blade comprising a guide bar and a plurality of cutting teeth positioned around a periphery of the guide bar and configured to rotate; and a gripper bar comprising a center section removably attached to the guide bar, an upper section extending upwardly from the center section, and a lower section extending downwardly from the center section. The gripper bar comprises a first gripping section on a proximal edge of the upper section, the first gripping section comprising a first plurality of teeth. The gripper bar further comprises a second gripping section disposed on a distal edge of the lower section, the second gripping section comprising a second plurality of teeth.

The invention provides a handheld power tool, which comprises a handle assembly, a power mechanism connected with the handle assembly, and a working mechanism connected with the power mechanism. The power mechanism comprises a main housing, an inner housing, and a motor disposed in the inner housing. The main housing comprises a first air inlet at a side wall thereof, the inner housing comprises an opening.
