Description STIHL MS 400‑1 Petrol Chainsaw – Professional Forestry and Heavy-Duty Performance The STIHL MS 400‑1 petrol chainsaw is a professional-grade tool designed for forestry, commercial land clearing, and demanding cutting tasks. Combining a powerful engine with lightweight construction, it delivers exceptional performance, versatility, and user comfort. Compact 64 cc 2‑MIX Engine Powered by a 64 cc 2‑MIX engine producing 3.9 kW (5.2 hp), the MS 400‑1 provides robust cutting performance while reducing fuel consumption and emissions by up to 20% compared to non-2‑MIX models. Durable, Long-Term Design The chainsaw features an HD2 long-life filter with pre-separation for reliable air intake and a decompression valve for easier pull starts. Its compensator carburettor maintains smooth engine performance even when the air filter begins to clog. Precision and Control Despite its power, the MS 400‑1 remains manageable with a 6.0 kg powerhead. The anti-vibration system reduces fatigue, and the soft-grip handle ensures comfort during long sessions. Side-mounted chain tensioning and captive sprocket nuts make bar and chain adjustments quick and safe. Efficient Lubrication Equipped with a variable oil pump compatible with Ematic guide bars and chains, this chainsaw delivers precise lubrication while reducing oil use. Tool-free fuel and oil caps and transparent tanks make refueling and oil checks fast and simple. Heavy-Duty Cutting Capability The MS 400‑1 supports 16–20″ guide bars, making it ideal for professional forestry operations. Wide metal bumper spikes provide stability and protect the chassis during tough cutting jobs.
