The STIHL MS 251 is a powerful and versatile petrol chainsaw. As a top-tier domestic saw, it’s the perfect choice for demanding property maintenance, cutting firewood, and timber construction tasks.
The STIHL MS 251 is an exceptional petrol chainsaw designed for homeowners, landowners, and farmers who require high performance for property maintenance. It’s the optimum choice for a variety of applications, from efficiently cutting firewood to tackling timber construction projects. Its high-torque engine delivers impressive cutting performance while being comfortable and easy to operate.
At the heart of the MS 251 is STIHL’s advanced 2-MIX engine technology. This innovative system significantly reduces environmental impact and running costs, cutting emissions by up to 70% and lowering fuel consumption by up to 20% compared to conventional STIHL 2-stroke engines of the same power output. This means you get a powerful, responsive chainsaw that’s kinder to your wallet and the environment.
STIHL has engineered the MS 251 with the user firmly in mind, incorporating several features to make operation safer, easier, and more comfortable.
Side-Mounted Chain Tensioning: This feature allows for protected, quick, and straightforward chain tensioning and replacement. The tensioning screw is conveniently accessed laterally through the sprocket cover, eliminating the need to touch the sharp chain.
Long-Life Air Filter System: The advanced air filter system features pre-separation routing, which removes larger particles from the airstream before they reach the HD2 filter. This process significantly extends the filter’s service life, reduces maintenance frequency, and ensures the engine is protected from even fine dust for long-term reliability.
Carburettor Compensator: This intelligent control system maintains a consistent engine performance, exhaust quality, and fuel consumption, even as the air filter becomes contaminated. This reduces the need for frequent maintenance, allowing you to work for longer without a drop in performance.
Tool-Free Fuel Caps: Refuelling is made simple with tool-free caps for both the fuel and oil tanks. The bayonet closure allows you to open and secure the tanks in just a few simple steps.
STIHL Ematic System: This system ensures highly efficient lubrication by delivering chain oil precisely where it’s needed, reducing oil consumption by up to 50%. The system comprises a specialised guide bar, saw chain, and a controlled-delivery oil pump.
STIHL Anti-Vibration System: To combat user fatigue, buffer and spring elements significantly reduce the transmission of engine vibrations to the handle area. This makes the MS 251 more comfortable to hold and operate, especially during prolonged use.
