A chainsaw (100) includes a power unit, a bar (120), a chain (122) operably coupled to the bar (120) to rotate around the bar (120) responsive to drive power from the power unit, an oil pump operably coupled to the power unit to deliver oil to the chain (122), and an oil 420 reservoir (400) configured to hold oil for delivery to the chain (122) via the oil pump. The oil reservoir (400) may include a main chamber (410) to receive the oil and an air chamber (420). The air chamber (420) may be formed adjacent to and distinct from the main chamber (410). The air chamber (420) is configured to define a space for an air pocket.

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 which a chain is rotatable. The guide bar (120) includes a first side plate (200) and a second side plate (210) facing each other and extending away from the housing (110) to a nose of the guide bar (120), the first and second side plates (200 and 210) each including an inner sidewall (224 and 222) facing inwardly toward each other. Each of the inner sidewalls (224 and 222) includes a recessed portion (230) at which material of the inner sidewalls (224 and 222) has been removed.

A chainsaw includes a housing including a handle housing portion, a motor housing portion, and a drive housing portion. The handle housing portion has a cavity extending along a longitudinal axis defining a first axis. A motor includes an output shaft having a longitudinal axis that defines a second axis. The chainsaw also includes a driven gear coupled to the output shaft, a sprocket coupled to the driven gear such that rotation of the driven gear rotates the sprocket, and a guide bar extending from the drive housing portion and having a longitudinal axis that defines a third axis of the chainsaw. The first and second axes define an included angle less than 75 degrees, the second and third axes define a second included angle between 110 degrees and 130 degrees, and the first and third axes define an external angle between 150 degrees and 170 degrees.

A chainsaw, a lubrication system for a chainsaw, and a lubricant for a chainsaw are provided. The chainsaw includes a lubrication system and guide bar extending from a housing. The lubrication system includes a reservoir at which a lubricant is contained. The reservoir is releasably attachable to a machine drive device. The machine drive device includes a body at which a pump apparatus is positioned. The machine drive device forms an inlet opening in fluid communication with the reservoir. The machine drive device forms an outlet opening at which a conduit is fluidly coupled to receive the lubricant. The conduit forms a conduit outlet through which the lubricant is provided to the guide bar.
