The new MS 251 is ideal for a variety of applications, from cutting firewood to timber construction. This high torque engine is easy to start and comfortable to use, with a high cutting performance. Emissions are cut by 70% and fuel consumption is up to 20% lower compared to a STIHL 2-stroke engine of the same power output without 2-MIX technology.
FEATURES
Reduced-emission engine technology
2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regulart 2-stroke engines and significantly reduced exhaust emissions.
Anti-vibration system
Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.
Pre-separation air filtration system
STIHL long-life air-filtration systems with pre-seperation achieve preceptibly longer filter life compared with convential filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-seperator duct.
Compensator
This controller in the carburator prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburator 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.
Side chain tensioner
The tensioning screw can be found on the side of the chainsaw through the sprocket cover. This removes the need for contact with the sharp saw chain.
Ematic chain lubrication System
The Ematic chain lubrication 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 convential methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.
Tool free filler caps
Special catches on the fuel and oil tanks for easy opening and locking without the need for tools.
