STIHL MS 400 C-M petrol chainsaw with chain bar and bar cover The MS 400 C-M features the latest and most innovative engine technology and is the first chainsaw to use a magnesium piston. Excellent power-to-weight ratio of 1.45 kg/kW. Technical data Displacement 67 cc Power 4 kW - 5.4 Hp Weight 5.8 kg Acoustic pressure level 107 dB(A) Acoustic power level 118 dB(A) 3/8" chain pitch Available in the following configurations: 1- Bar length: 45 cm 2- Bar length: 50 cm Features - STIHL M-TRONIC SYSTEM RELIABLE WORKING WITH THE BEST PERFORMANCE. Thanks to STIHL M-Tronic, you can get the best performance from your machine right from the start. The fully electronic engine management system adjusts ignition timing and fuel metering at all operating conditions, taking into account external factors such as temperature, altitude and fuel quality. - STIHL ANTI-VIBRATION SYSTEM MORE PLEASANT WORKING ENVIRONMENT. The power output of the implement generates vibrations that are felt especially in the grip area. The STIHL anti-vibration system's shock absorbers and compensating elements reduce the transmission of engine vibrations to the handle and thus to the user's body. As a result, the device can be held more comfortably and allows less fatigue during work. - EASY-TO-USE COMBINATION LEVER WITH STOP FUNCTION. Only one starting position is required on the combined lever. After switching off, the control lever automatically returns to the operating position thanks to the stop function. If the engine is still warm, it can be restarted directly. - PARTICULARLY ENERGY-EFFICIENT STIHL 2-MIX ENGINE. The STIHL 2-Mix engine not only reduces exhaust emissions, but also fuel consumption and the associated running costs. This 2-stroke engine requires little maintenance and uses fuel efficiently even at high performance. The fuel consists of a mixture of petrol and engine oil. The STIHL 2-Mix engine complies with the strict European Stage V emissions directive. - HD2 filter The new HD2 filter with polyethylene filter material has 70 per cent finer pores than felt and polyamide filters, enabling it to filter out even the finest dust particles. It is also water-repellent and therefore easy to clean. The PET-coated filter core can be fitted and removed in no time at all without tools. - MANUAL DECOMPRESSION EFFORTLESS START-UP. The decompression valve facilitates starting the device. During starting, part of the compressed mixture can be discharged from the cylinder by opening the valve. This protects the starter system and reduces the use of force on the starter rope. - SIDE CHAIN TENSIONING EASY AND SAFE TENSIONING. The side chain tensioner enables simple, fast and safe chain tensioning and replacement. The tensioning screw is operated laterally through the sprocket cover. - Adjustable oil pump Different cutting lengths, types of wood and working techniques require different amounts of oil. The oil pump with adjustable flow rate allows the oil flow rate to be precisely adjusted according to requirements. It is possible to reduce the amount of oil fed in by up to 50%. - AIR FILTER WITH LONG-LIFE PREFILTERING FOR LONGER FILTER LIFE. Prefiltering removes coarse and larger particles from the air stream before they can reach the actual filter. The HD2 filter also keeps fine dust particles away from the engine, thus ensuring a long service life for the engine, longer cleaning intervals and easy servicing of the chain saw. Only if the chain saw is equipped with a prefilter and HD2 filter can one speak of a long-lasting air filter system. In fact, this system allows a considerably longer filter life than conventional air filter systems. - REDUCED MAINTENANCE COMPENSATOR. By means of pressure compensation, a regulating system in the carburettor known as the compensator, it is ensured that despite the increased fouling of the air filter, engine power, exhaust gas quality and fuel consumption remain almost constant over a long period of time. Therefore it is only necessary to clean the air filter when a noticeable decrease in performance is noticed. In this way it is possible to work for a long time without maintenance. - Anti-leakage nuts In the chain sprocket cover assembly the nuts are constantly in the correct position, with no possibility of tilting only a few manoeuvres are required. Each nut can be tightened independently of the others. - STIHL 1-in-4 duct technology 1-in-4 duct technology - high torque over a wide range of engine speeds - electric carburettor heating The carburettor heater, with temperature-dependent switching on and off, prevents the carburettor from freezing during winter use. - Magnesium piston The magnesium piston in combination with the consistent, lightweight construction leads to some real highlights. Excellent power-to-weight ratio. Fast acceleration and high torque. - OIL AND FUEL TANK CAP FOR EASY AND QUICK OPENING AND CLOSING. The oil and fuel tank can be opened and closed in a few easy steps thanks to the tool-free opening and closing bayonet lock. - STIHL EMATIC SYSTEM REDUCED OIL CONSUMPTION. The STIHL Ematic system consists of the STIHL Ematic or Ematic S guide bar, the STIHL Oilomatic chain and an adjustable oil pump. It ensures that the chain oil gets to where it's needed for lubrication. This can reduce oil consumption by up to 50%. If you often work in dusty environments or use longer guide bars, you can easily and quickly increase the oil quantity at any time with the new oil pump system. CZ
