With 3/8″ Picco Super, full chisel tooth saw chain and M-Tronic as standard. The fuel supply is electronically controlled and automatically adapts to operating and ambient conditions, ensuring engine optimal performance. The memory function allows you to quickly pick up where you left off after a break in work and there is no need to adjust the settings by hand. Additional practical features include the long-life air filter system with easy-clean HD2 filter, professional STIHL anti-vibration system, controlled-delivery oil pump, captive nut on the sprocket cover and one piece engine cover with three quick-release fasteners.
This air filter keeps even the finest dust away from the engine, ensuring a particularly long service life. Thanks to special material, the filter can be washed clean, for example with STIHL Variocleanand warm water.
The long-life air filter system has a service life up to five times longer than the previous model. The newly developed HD2 filter is made from a water- and oil-repellent polyethylene filter material. It has up to 70 per cent finer pores than fleece and it is easy to clean. The PET-coated round filter cartridge with quick-release lock enables the filter to be fitted and removed in next to no time.
A pre-separation air filtration system
The innovative long-life air filter system greatly extends the service life of the filter. Air routing removes larger particles of dirt, meaning the actual filter has less to do. So the saw can be used for longer without having to clean the filter.
The decompression valve is part of the easy start-system. The valve should be pressed before starting in order to reduce the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic, meaning that it must be pressed manually before starting, but then closes automatically.
For a cold start, the STIHL M-Tronic only needs one start position on the combi-lever. After starting, you can immediately power up to full speed. The amount of fuel required is precisely calculated by the system and supplied as needed. Otherwise, start in position I as usual.
Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result: lower consumption and high torque across a broad rpm range.
Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system whereby the oscillations from the machine’s engine are dampened which significantly reduces vibrations at the handles.
This controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn’t need to be cleaned until an appreciable drop in power occurs.
Bar nuts held captive in the sprocket cover will not get lost when changing over the cutting attachment.
The exact chain oil output can be adjusted manually for varying conditions, allowing for a reduction of up to 50%.
All important functions such as start, choke, throttle and stop are operated via a single lever.
The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption up to 50%.
