  STIHL Anti-vibration system

  The STIHL anti-vibration system is available in a one-point version for smaller models and in an especially effective four-point version for larger machines starting with the STIHL. It reduces handle vibration for easy and comfortable operation.

  Multi-function control handle

  Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.
