Compared to industry standards and previous models, the MS 391 stands out with its superior power-to-weight ratio of 1.9 kg/kW, offering excellent manoeuvrability without compromising performance. Its sophisticated combustion system ensures lower fuel consumption and consistent torque over a broad rev range, making it more economical and environmentally friendly than many competitors. Enhancements such as the Ematic chain lubrication system reduce oil usage by up to 50%, representing a significant improvement in operational efficiency.

Key Technical Advantages:

The STIHL MS 391 excels in technology and performance through several innovative features. The semi-automatic decompression valve simplifies starting by reducing compression pressure, which reduces effort when pulling the starter rope. Its advanced four-channel combustion technology optimises the fuel-air mixture, resulting in efficient combustion and high torque output.

A comprehensive anti-vibration system minimises fatigue and protects operators against long-term vibration-related injuries, ensuring greater comfort during prolonged use. The pre-separation air filtration system significantly extends filter life by removing larger particles before they reach the main filter, maintaining engine performance for longer periods. Additionally, the compensator maintains the correct fuel-air ratio regardless of filter clogging, stabilising engine power and reducing maintenance frequency.

Further user-friendly features include a single-lever master control that consolidates start, choke, throttle, and stop functions into one simple operation, enhancing ease of use. The side-chain tensioner allows quick adjustments away from the sharp chain, increasing safety. The variable-displacement oil pump gives precise, demand-based oil delivery with the possibility to adjust output depending on cutting requirements. Tool-free filler caps simplify refuelling and oiling without needing additional tools.

For those requiring reliable and high-performing garden machinery, the STIHL MS 391 petrol chainsaw delivers outstanding power, reduced emissions, and user-focused design enhancements, making it a premium choice in agricultural and landscaping petrol chainsaws.
