The work apparatus comprises reduced wear, in particular with respect to a liquid medium.
Claims20
A hand-held work apparatus for processing a material, comprising:
- a tool which, in an operating state of the work apparatus, is configured for cutting, separating, and/or grinding the material;
- a drive unit which is coupled to the tool via a drive means in order to drive the tool;
- a boom which extends in a longitudinal direction between the drive unit and the tool and is configured to rotatably support the tool about a rotation axis by means of a tool bearing unit;
- wherein a cover housing part is arranged on the boom, which extends along the longitudinal direction and comprises a housing end edge,
- wherein a drainage structure with at least one drainage structure section is arranged on the cover housing part, which drainage structure section is formed, originating from the housing end edge, in a raised manner in order to delimit a flow surface on the cover housing part for a flowing medium in the longitudinal direction.
