Anti-Vibration System

Intense vibration at the handles of power tools can lead to long-term affects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machines engine are dampened to reduce vibration at the handles.

Water Supply

Water is supplied to the cutting wheel through the standard water connection with sprinkler system to suppress the dust produced during cutting. It is supplied to the machine in such a way so as to not interfere with your work
