Description STIHL MS 251 Petrol Chainsaw – Powerful, Efficient & Easy to Use The STIHL MS 251 petrol chainsaw is a high-performance, all-round model designed for demanding garden work and light forestry tasks. Perfect for cutting firewood, felling small trees, and general maintenance, it delivers professional-level power in a compact and easy-handling design. Efficient 2-MIX Engine Driven by a 45.6 cc STIHL 2-MIX engine, the MS 251 produces impressive torque while reducing emissions by up to 70% and fuel use by 20% compared to traditional two-stroke engines. This makes it both powerful and environmentally responsible. Comfortable Handling & Control Weighing just 4.8 kg (without bar and chain), the MS 251 offers an excellent power-to-weight balance. The anti-vibration system and soft-grip handle minimise operator fatigue, allowing you to work longer with greater precision and comfort. Smart, User-Friendly Features A single-lever master control combines choke, start, throttle, and stop functions for effortless operation. Transparent fuel and oil tanks allow for quick level checks, while side-mounted chain tensioning ensures safe and simple chain adjustments using a tool. Durable & Low-Maintenance Design The long-life air filter system with pre-separation and a compensator carburettor maintains consistent engine performance as the filter collects debris. Tool-free filler caps make refuelling and oiling quick, clean, and convenient. Versatile Cutting Performance Compatible with 35 cm (14″), 40 cm (16″), and 45 cm (18″) guide bars, the MS 251 is equipped with a narrow-kerf 3/8″ P Picco Micro 3 (PM3) chain for fast, clean cuts — ideal for a wide range of wood-cutting applications.
