The Stihl MS 660 first appeared in 2002 when Stihl re-branded their products. It is actually the old Stihl 066 and it is still made today.

The ElastoStart shock absorber handle of this Stihl power tool ensures the user’s safety. In case the filter starts to clog, the IntelliCarb Compensating Carburetor of this Stihl chainsaw takes care of maintaining the RPM level. The Anti-Vibration System of the Stihl MS 660 helps in reducing the operator’s fatigue. With the inboard chain brake of this Stihl power tool, removing the chain sprocket is convenient.
