MS 661 C-M gas chainsaw: Professional chainsaw with cutting-edge technology for forestry work

The STIHL MS 661 C-M professional chainsaw is a real powerhouse, offering strong and consistent performance. It combines cutting-edge technology with an optimum power-to-weight ratio of 1.4 kg/kW and is ideal for particularly tough and demanding forestry applications. Even thick wood can be processed effectively and quickly using this gas-driven chainsaw.

The chainsaw is powered by a 5.4 kW (7.3 hp) STIHL 2-MIX engine, which ensures consistently high performance thanks to STIHL M-Tronic. The controlled-delivery oil pump reliably supplies the cutting attachment with oil and enables the use of long and extra-long guide bars.

The STIHL MS 661 C-M gas chainsaw is also used as a competition saw in the STIHL TIMBERSPORTS® series.

Additional features of the STIHL MS 661 C-M:

• The HD2 air filter removes even the finest dust particles from the air and can be easily cleaned using STIHL VarioClean.
• The STIHL anti-vibration system ensures comfortable operation and helps reduce strain on muscles and joints.
• Tool-free fuel caps save time and effort during refuelling.
