Abstract: 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.

Abstract: A handle assembly can include a handle extending from a work portion of the power tool. The handle can include a handle member configured to be engaged by a user when operating the power tool and at least one elongated member extending between the work portion of the power tool and the handle member. A multi-position interface can be spaced apart from the handle member and define a plurality of engagement interfaces. An engagement element can be configured to move relative to the multi-position interface and be selectively engageable with the plurality of engagement interfaces. A user engageable interface can be configured to selectively move the engagement element into and out of engagement with the plurality of engagement interfaces. The handle assembly can be angularly repositionable between a plurality of angular orientations when the engagement element is not disposed within any of the plurality of engagement interfaces.
