STIHL - 1144-200-0319 - Petrol Chainsaw MS 661 C-M 7.3 hp Guide Bar Length 71 cm

Chainsaw | power 5.4 kW 7.3 hp with M-Tronic system for the heaviest forestry work Professional STIHL MS 661 C-M chainsaw is true power among chainsaws, offering high and consistent performance. It combines the latest technology with an optimal power-to-weight ratio of 1.4 kg/kW and is ideal for particularly difficult and demanding forestry applications. Even thick wood can be processed efficiently and quickly with this petrol chainsaw. The saw is powered by a STIHL 2-MIX engine with a power of 5.4 kW (7.3 hp), which ensures consistently high performance thanks to STIHL M-Tronic. The oil pump with adjustable output reliably supplies the cutting set with oil and enables the use of long and very long guide bars. The STIHL MS 661 C-M petrol chainsaw is also used as a chainsaw in STIHL TIMBERSPORTS® competitions. Other features of the STIHL MS 661 C-M chainsaw: The HD2 air filter removes even the finest dust from the air and is easy to clean with STIHL VarioClean. The STIHL anti-vibration system enables comfortable work and protects muscles and joints. Tool-free fuel filler caps save time when filling the saw's tank with fuel. Groove width Chain pitch Device length with claw stop Sound pressure level Sound power level Vibration level left side Vibration level right side ENSURES EASY AND SAFE TENSIONING. The side chain tensioner enables safe, easy and quick tensioning and replacement of the chain. The tensioning screw is accessible from the side through the chain drive cover. RELIABLE OPERATION WITH THE HIGHEST PERFORMANCE. The STIHL M-Tronic system ensures the highest performance of the device immediately after starting. The fully electronic engine control system regulates the ignition timing and fuel delivery taking into account external conditions such as temperature, altitude and fuel quality. Allows precise, needs-based lubrication. The E marking guarantees the delivery of the appropriate amount of oil in all working conditions. Professionals dose precisely. The pump allows oil consumption to be reduced by up to 50%. The new HD2 filter is made of polyethylene and has pores up to 70% finer compared to fleece or polyamide filters, which in practice means filtering the finest contaminant particles. The new filter is also waterproof, does not absorb oil and can be easily cleaned. The round filter cartridge can be removed without tools. The carburetor adjustment system, the compensator, by equalizing pressure, ensures that despite increasing air filter contamination, engine power, exhaust quality and fuel consumption remain almost unchanged for a long time. Therefore, the air filter should only be cleaned after a clear drop in parameters. This allows long periods of maintenance-free operation. Thanks to the tool-free tank closure, the oil and fuel tank can be easily opened and closed with a bayonet closure. The STIHL Ematic system consists of a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and an oil pump with adjustable flow. It guarantees that chain oil reaches where it is needed for lubrication. This allows oil consumption to be reduced by up to 50%. When working in very dusty conditions or using long guide bars, the oil quantity can be easily and quickly increased at any time thanks to the new oil pump system. STIHL chainsaws equipped with a carburetor preheating system are reliable even when it is cold outside: in winter operating mode, heated air flows around the carburetor. This solution effectively prevents carburetor icing. When replacing the cutting set, a practical sprocket cover nut with loss protection is used. The decompression valve makes starting the device easier. Opening the valve during start-up allows part of the compressed mixture to be released from the cylinder. This protects the starting system and requires less force on the starter rope. Only one starting position is required on the multi-function lever. After switching off, thanks to the STOP function, the control lever automatically returns to the working position. This allows the warm machine to be restarted immediately. This 2-stroke engine is designed to require little maintenance and consume fuel even at high power. A mixture of gasoline and engine oil should be used as fuel. The STIHL 2 Mix engine meets the requirements of the strict EU exhaust emission directive, level V. ENSURES MORE COMFORTABLE WORK. When the device's power increases, vibrations are generated that are particularly noticeable in the handle area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and thus to the user's body. Effect: The device sits more comfortably in the hand and work is much less tiring.
