STIHL MS 291 450mm (18") 2.8kW 55.5cc Yard Boss 2-Stroke Petrol Chainsaw

Description:

Powerful, robust chainsaw for all-round use, with up to 20% less fuel consumption and up to 50% fewer emissions compared to STIHL two-stroke engines of the same performance class without 2-MIX technology. Easy to maintain and service. Long-life air filter system with air routing, one piece engine cover. Great for cutting firewood. Environmentally-friendly and economical 2-MIX engine.

Features:

• 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.
• 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.
• Anti-vibration system
  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.
• Compensator 
  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.
• Single-lever master control
  All important functions such as start, choke, throttle and stop are operated via a single lever.
• STIHL Ematic-System 
  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%.
• HD2-Filter 
  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.
