Handheld work apparatus with a brake unit

Abstract

A handheld work apparatus includes a tool and a brake unit for the tool. The brake unit includes a brake band and a brake drum. The brake band wraps around the brake drum. The brake unit is configured such that, during braking, a friction surface of the brake band is in contact with a friction surface of the brake drum, with the result that the brake band and the brake drum form friction partners. At least one of the friction surfaces is configured before a first braking operation on a wear layer, the thickness of the wear layer being from 0.5 μm to 3 μm or the thickness of the wear layer being from above 3 μm to 20 μm, and the wear layer containing Fe2O3 and/or FeO.
