MS 181 C-BE PM3 New, lightweight STIHL chainsaw with 2.0 Hp petrol engine, with ErgoStart system and chain accelerator 1) No fuel, blade and chain 2) Coefficient K according to Directive 2006/42 / EC = 2.5 dB (A) 3) Coefficient K according to Directive 2006/42 / EC = 2m / s β Cubic capacity cm³ 31,8 Power kW / HP 1,5 / 2 Weight kg 1) 4,6 Sound pressure level dB (A) 2) 100 Sound power level dB (A) 2) 112 Left / right vibrations m / s² 3) 3,5 / 3 Power to weight ratio kg / kW 3,1 Step / chain type 3/8 "P Standard Long-lasting air filtration system The air filtration system long with a separation cyclone ensures substantially longer filter life. the separation cyclone having removes large dirt particles, in order not to burden the filter, thus doubling the time until the next cleaning. anti-vibration long run, strong vibrations on the handles of machines can cause problems in the perspiration of fingers and hands To prevent this problem, STIHL has developed a high quality anti-vibration system. In machines with anti-vibration system, the transmission to the handles of the oscillations produced by the motor and the component is significantly reduced. Pressure compensator The STIHL pressure compensator, a regulator built into the carburetor, ensures that engine performance, exhaust quality and fuel consumption remain almost constant over an extended period of time, despite progressive air pollution. Ematic Chain Lubrication System The STIHL Ematic-System consists of an Ematic blade, an Oilomatic chain and an adjustable or reduced flow oil pump. The special construction of the blade and the chain ensures that every drop of oil reaches where it really needs lubrication. Thus oil consumption can be reduced by up to 50%. Multi-function lever The basic functions of the machine, such as cold and hot start, operation and stop, are controlled by a single lever. This makes handling extremely easy and safe, as the operator does not have to move his right hand away from the handle. Perfect combustion Four overflow chambers swirl the fuel-air mixture before ignition. In this way the fuel burns perfectly and the engine efficiency is significantly increased. The result: Lower fuel consumption and higher torque over a wide range of speeds. Quickstop chain brake The QuickStop chain brake provides extra safety when operating the chainsaw. The chain brake is activated via the front hand guard and immobilizes the chain in fractions of a second. The Quickstop chain brake is activated automatically in the event of a possible kick. Lateral chain tensioner With the side tensioner, the chain is stretched from the side, through the bell cap. This avoids the contact of the hands with the sharp chain and the support nails of the chainsaw. Tank cap that opens without tools Special secured plugs for the fuel tank and the oil tank. In machines with such plugs, the tank and the oil tank open and close quickly, with minimal force and without tools. ErgoStart System Easier to start than ever. In the new ErgoStart system, there is an additional coil spring between the starter pulley and the crankshaft, which compresses against the compression pressure exerted on the piston. When the spring force exceeds the compression pressure, the crankshaft will start to rotate, starting the engine. The machine starts smoothly and comfortably, without annoying fluctuations in the required power.
