Quiet, low-vibration operation

The STIHL anti-vibration system significantly reduces vibrations transmitted to your hands and arms, making the fsa400 more comfortable to use for extended periods. It’s also quiet enough for work in noise-sensitive areas such as residential sites or near public facilities.
