Its separation cyclone removes large particles of pollutants, so as not to burden the filter, thus doubling the time until the next cleaning. STIHL M-Tronic Fully electronic engine control system regulates ignition timing and fuel supply in each operating mode, taking into account external factors such as temperature, altitude and fuel quality. Ensures excellent engine performance and very good acceleration. No need to adjust the carburetor manually. In addition, the M-Tronic records the settings from the last use so that at each restart you immediately have the full power of the engine. 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. HD2 - New filter New HD2 filter: The new HD2 high density polyethylene filter has 70% thinner pores than nonwoven and polyamide filters, thus capturing even the finest dust. In addition, it repels water and oil and for this reason it is very easy to clean. The replacement filter is removed and installed without tools. Anti-vibration system In the long run, strong vibrations in the handles of machines can cause problems with the perspiration of the 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. Bell cap with safety nuts The nuts are permanently attached to the bell cap. This way the nuts are not lost, they are always properly positioned and do not warp when the lid is installed. Adjustable flow oil pump Allows accurate oil supply depending on operating conditions. The setting on the E indicator guarantees an adequate oil supply under all conditions. However, as professionals adjust the flow more precisely, the pump allows the oil flow to be reduced by up to 50%. Similar image Side 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. 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%. ElastoStart system When pulling the starter rope on internal combustion engines, the compression pressure creates sudden power fluctuations that put strain on the muscles and joints. A shock absorber integrated in the special ElastoStart start handle absorbs and releases force, depending on the compression course. This normalizes the boot process and eliminates jerks. Carburetor preheating system STIHL chainsaws with carburetor preheating can be relied on even during the colder months of the year: With winter setting, preheated suction air passes around the carburetor. This prevents the carburetor from freezing. A simple move is enough to switch between summer and winter mode. 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.
