Abstract
The invention is directed to a braking arrangement for a chain saw and includes a brake band and a brake drum which form friction partners with their associated friction surfaces during braking. At least the friction surface of one of the friction partners includes a material which is resistant to conversion to martensitic structure. Particularly suitable materials are those having a cubic face-centered lattice structure, such as, for example, austenitic steel or chrome-nickel steel.
