Chain saw for grounds maintenance. Extensive features such a long-life air filter system and STIHL anti-vibration system. Great for cutting firewood, for building and for felling small trees. Up to 20% less fuel consumption and up to 70% fewer emissions compared to STIHL two-stroke engines of the same performance class without 2-MIX technology.

STIHL 2-MIX Engine:
The new 2-MIX engine features an advanced stratified charge system that boosts power, whilst reducing consumption and pollution, significantly lowering unburned hydrocarbons in the exhaust. The result is a cleaner, more fuel efficient engine.
Advanced combustion technology:
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.
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.
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 where by the oscillations from the machines engine are dampened which significantly reduces vibrations at the handles.
Tool free filler caps
Special caps on the fuel and oil tanks are designed for easy opening and locking without the need for tools.
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.
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%.
Side chain tensioner
The tensioning screw is located on the side of the chain saw through the sprocket cover. Chain side tensioning allows the saw chain to be retensioned effortlessly, avoiding any contact with the sharp chain.
Single-lever master control
All important functions such as start, choke, throttle and stop are operated via a single lever.
STIHL Quick Chain Tensioning (B)
After loosening the sprocket cover the chain can be adjusted using a thumb wheel without the need for tools.
STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the users joints and muscles through a spring or rubber element in the starter handle.
