The STIHL MS 261 is a versatile professional chainsaw built for demanding work, from cutting firewood to thinning and felling. Its redesigned cylinder and ergonomic housing provide an impressive power-to-weight ratio, giving you strong cutting performance in a well-balanced saw.
Redesigned bumper spikes help provide better control while cutting, and the STIHL anti-vibration system helps reduce fatigue when there’s a full day of work ahead. Designed to spend more time cutting and less time on maintenance, the MS 261 features a pre-separation air filtration system that doubles the time between filter cleanings.
A decompression valve and STIHL ElastoStart™ help make starting easier, while the side-access chain tensioner makes chain adjustments more convenient. Toolless fuel and oil caps simplify refueling and adding bar and chain oil. With low exhaust emissions, high fuel efficiency, and professional-grade performance, the MS 261 is a dependable saw built for the variety of work professionals take on every day.
