MS 661 C-M R petrol chainsaw: cutting-edge technology for forestry
The STIHL MS 661 C-M R professional chainsaw is a real powerhouse, offering strong and consistent performance. It combines cutting-edge technology with an optimal power-to-weight ratio of 1.4 kg/kW and is ideally suited to particularly tough and demanding forestry applications. The gas chainsaw can process even hard wood effectively and quickly.
The chainsaw is powered by a 5.4 kW (7.3 hp) STIHL 2-MIX engine, which ensures constant high performance thanks to STIHL M-Tronic. The controlled-delivery oil pump reliably supplies the cutting attachment with oil and facilitates the use of long and very long cutting attachments.
The STIHL MS 661 C-M R gas chainsaw is also used in the STIHL TIMBERSPORTS® series as a competition saw. Other features of the STIHL MS 661 C-M R chainsaw:
- The HD2 air filter removes even the finest dust from the air and is easy to clean with STIHL VarioClean. In a video tutorial, we will demonstrate how to perform the cleaning.
- The STIHL anti-vibration system allows you to work comfortably and is gentle on muscles and joints.
- The loop handle makes sawing easier, as the chainsaw can be held more comfortably when cutting,
while tool-free fuel caps save your time and energy when filling the chainsaw.
