Description

STIHL MS 251 – COMPACT AND POWERFUL

The STIHL MS 251 is a compact yet powerful petrol chainsaw designed for demanding homeowners and landowners who need high performance for property maintenance, firewood cutting, and light forestry work. Combining excellent cutting power with fuel efficiency and low emissions, this model is a versatile workhorse built to handle a wide range of outdoor tasks with ease.

At the heart of the MS 251 is STIHL’s advanced 45.6cc 2-MIX engine, which delivers 2.2 kW (3.0 hp) of power while significantly reducing fuel consumption and exhaust emissions compared to traditional 2-stroke engines. This makes it not only efficient but also more environmentally friendly—ideal for users who want performance without compromise.

Designed for user comfort and control, the chainsaw features STIHL’s anti-vibration system, which reduces handle vibrations for a smoother operating experience and less fatigue during extended use. Starting the MS 251 is quick and reliable thanks to a simplified starting process and a side-mounted chain tensioner that allows for easy, safe adjustments without removing the sprocket cover.

Another highlight of the MS 251 is its pre-separation air filtration system, which ensures longer run times between filter cleanings by removing larger dust particles before they reach the air filter. This helps prolong engine life and ensures consistent performance even in dusty or challenging environments.

Weighing just 4.8 kg (excluding fuel, bar, and chain), the MS 251 offers an ideal power-to-weight ratio. It’s compatible with guide bars from 16” to 18″, giving you flexibility depending on your cutting needs—whether you’re pruning limbs, felling small trees, or splitting logs for firewood.

With its durable construction, advanced engine technology, and ergonomic design, the STIHL MS 251 is a reliable, high-performance tool for anyone serious about outdoor property care.
