HD2 filter The new HD2 filter with polyethylene filter material has 70 per cent finer pores than felt and polyamide filters, thanks to which it can filter out even the finest dust. In addition, it is oil water-repellent and thus easy to clean. In no time at all, the PET-coated filter core can be fitted and removed without tools. STIHL 2-MIX engine The STIHL 2-MIX engine is powerful and economical at the same time. The separation of exhaust and inert gas minimises unburned particle emissions, increasing performance and saving on fuel consumption. STIHL M-Tronic (M) Fully electronic fuel metering and ignition point adjustment. STIHL M-Tronic (M) ensures optimum engine performance, constant engine speed and optimum acceleration behaviour in every operating state. Manual adjustment of the carburettor is dispensed with. Single-lever control All functions such as starting, running and stopping can be controlled with one hand. Compensator Allows a constant fuel-air mixture even in the event of increased dirt in the air filter. ElastoStart Thanks to the unique STIHL ElastoStart starting handle, in combination with the manual fuel pump and decompression valve, kickback when starting is significantly reduced. Adjustable flow 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%. Vibration-damping system Precisely positioned vibration-damping zones reduce the transmission of vibrations from the motor and chain to the handle and handle. Ematic chain lubrication system Depending on the type of bar and type of wood, the STIHL Ematic system reduces chain oil consumption by up to 50%. It consists of the Ematic bar, Oilomatic chain and an oil pump with adjustable, reduced flow rate. This ensures that the lubricant reaches exactly where it is needed in a targeted manner and with little loss. Tool-free tank cap Special caps for the fuel tank and oil tank for easy opening and closing. Side chain tensioner The chain is tensioned laterally through the sprocket. Any contact between the operator's hand and the sharp chain is thus avoided. Decompression valve The decompression system automatically opens the inlet valve. This absorbs pressure peaks and reduces the amount of force required on the starter rope. ORIGINAL PART NUMBER: 1144 200 0371 1144-200-0371 11442000371 CZ
