Stihl's MS 201 C-M chain saw is the latest development in technology for arborists and forestry professionals. The STIHL M-Tronic™ technology provides easier starting with a cold/warm start recognition system that calculates the exact fuel dosage without the need for a choke position in the Master Control Lever™. There are no manual adjustments required for the fuel dosage as it is electronically calculated, while taking into account external conditions. The STIHL M-Tronic™ technology ensures fast and responsive acceleration event from a cold start and it remembers your previous settings indefinitely and restores them when you restart the chain saw.
