STIHL MS 400 C-M Petrol Chainsaw

Professional Power, Precision, and Innovation

The STIHL MS 400 C-M Petrol Chainsaw is a groundbreaking tool built for forestry and arborist professionals who demand exceptional performance and durability. Designed with cutting-edge engineering, it is the world’s first chainsaw to feature a magnesium piston, offering increased displacement, higher torque, and a class-leading power-to-weight ratio. With a 66.8cc engine, this professional-grade chainsaw delivers 4.0kW of power, providing 14% more displacement and torque compared to the STIHL MS 362 C-M.

Exceptional Power-to-Weight Ratio

The magnesium piston design not only increases displacement but also reduces overall weight, creating an impressive power-to-weight ratio of 1.45 kg/kW. This ensures high efficiency and effortless handling during prolonged use. The chainsaw’s lightweight construction supports excellent balance, making it ideal for demanding forestry work such as felling, de-limbing, and cutting timber. With a powerhead weight of just 5.8kg, the MS 400 C-M offers exceptional control and comfort, even during intensive operation.

Reliable Honda GXV160 Engine

At its heart lies the STIHL 2-MIX engine, delivering powerful acceleration, reduced fuel consumption, and lower emissions. This high-performance engine provides a smooth, consistent power output while meeting strict EU Stage V emission standards. Its four-channel technology ensures efficient combustion, significantly improving fuel economy and enhancing cutting performance.

Intelligent STIHL M-Tronic 3.0 System

The advanced STIHL M-Tronic 3.0 system ensures optimal engine performance under all working conditions. This fully electronic engine management system automatically regulates ignition timing and fuel metering, adapting to temperature, altitude, and fuel quality. The re-calibration process is quick and simple, ensuring maximum reliability and consistent power delivery with every use.

Advanced Filtration and Long Service Life

The HD2 filter provides superior filtration, protecting the engine from fine dust and debris. Its PET material construction offers up to 70% finer pores than standard filters, improving air quality and extending service life. Combined with pre-separation routing, coarse particles are removed before reaching the filter, increasing efficiency and reducing maintenance frequency. This design ensures the chainsaw remains dependable and powerful for extended periods.

Built for Durability and Comfort

The cast magnesium construction gives the MS 400 C-M superior strength and heat resistance, ensuring long-lasting durability under demanding conditions. STIHL’s anti-vibration system minimises fatigue by reducing handle vibrations, allowing longer working periods with less strain. The ElastoStart system and decompression valve make starting effortless, reducing pull resistance and extending starter life.

User-Focused Design for Professionals

This chainsaw includes practical innovations that enhance productivity and ease of use. The blade brake clutch system allows the user to stop the chain without shutting off the engine, improving workflow efficiency. The tool-free fuel caps enable quick refilling, while the side-mounted chain tensioner allows safe, convenient chain adjustments. The fan-assisted cooling system ensures consistent airflow, maintaining engine temperature during heavy workloads.

Efficiency and Environmental Responsibility

The controlled-delivery oil pump reduces oil consumption by up to 50%, allowing precise lubrication depending on workload and wood type. The STIHL Ematic system directs oil exactly where needed, improving performance while lowering waste. Together, these innovations reduce operational costs and environmental impact.
