Abstract

A manually guided implement having a drive motor is provided. For a translatory movement of a tool member, the rotational movement of the drive motor must be converted by a gear arrangement, which has a gear wheel that is coupled with a component that glides on the end face of the gear wheel. To significantly reduce frictional losses and also wear of the pertaining components, a constantly effective, reliable lubricant is required. For this reason, at least one cutout is provided in the main body of the gear wheel and/or in the component that can glide on the end face thereof. Such cutouts are open to a glide plane and serve to accommodate a lubricant.
