STIHL MS 661 C-M Picco petrol chainsaw, without guide bar and chain

The STIHL MS 661 C-M Picco is a professional 2-MIX chainsaw with M-Tronic, configured for use on compatible LOGOSOL and other chainsaw mills. Felling and cross-cutting require a suitable cutting attachment. Guide bar and chain are not included. A 3/8″ P (Picco) drive sprocket is fitted, and the sprocket cover uses separate removable nuts for sawmill mounting. Supplied with a combination wrench and Estonian instruction manual. Equipment includes an adjustable oil pump, HD2 filter, tool-free tank caps, stainless-steel muffler, quick-release engine cover, anti-vibration system, decompression valve and ElastoStart. For ripping, choose compatible 3/8″ P guide bars with 1.3 mm gauge, 32–63 cm long, and PMX chains sharpened to 10°. Example: a 45 cm LOG bar and a 1.3 mm PMX chain with 66 drive links. Conversion to 3/8″ RAPID requires a different sprocket: a 3/8″ Z7 spur sprocket, code 11226402002, or a 3/8″ Z7 rim sprocket kit, code 11220071000. After conversion, select compatible 3/8″ bars with 1.6 mm gauge and RM, RS or RD chains of the correct length. Example: a 50 cm ES Light bar with a 1.6 mm RAPID HEXA RH chain with 72 drive links. Selection and conversion must follow the saw and sawmill manuals.
