The band brake wraps around the clutch drum of the STIHL chainsaw and engages when the brake lever is pushed or on kickback. It is an operator safety feature. Manufacturer: EMAS.
The band needs to be replaced if it is worn through, torn, or does not hold the drum: the chain keeps rotating with the brake engaged. It is worth checking the brake before every job.
Before buying, check your saw model: for Chinese saws and their analogues, parts of different generations may differ, so rely on the marking and comparison with the old part.
