The STIHL MS 391 Petrol Chainsaw is a powerful, high-torque all-round petrol chainsaw built for demanding work in agriculture, estate maintenance, timber construction and serious firewood processing. Designed for users who need strong cutting performance with excellent durability, the MS 391 is a dependable choice for heavy-duty ground work and regular saw use.
Powered by a 64.1cc STIHL 2-MIX engine, the STIHL MS 391 delivers a strong 3.3kW output with excellent torque across a wide rev range, making it ideal for cutting larger timber, processing firewood and general farm or land management work. It also offers improved efficiency, with lower fuel consumption and reduced emissions compared to older non-2-MIX models. :contentReference[oaicite:0]{index=0}
If you need a STIHL petrol chainsaw with real cutting authority, straightforward handling and strong long-term reliability, the MS 391 is a serious workhorse.
Key Features
- Powerful 64.1cc STIHL 2-MIX engine
- 3.3kW power output for demanding cutting tasks
- Ideal for firewood, timber construction and agricultural use
- Manual decompression valve for easier starting
- Side-mounted chain tensioning for fast adjustment
- Controlled-delivery oil pump for reduced oil consumption
- STIHL Ematic system for efficient chain lubrication
- Long-life air filter system for extended service intervals
- Tool-free fuel and oil caps for quick refuelling
- STIHL anti-vibration system for greater comfort
Built for Heavy-Duty Cutting
The STIHL MS 391 is designed for users who regularly tackle bigger, tougher cutting jobs. Its strong torque characteristics make it especially effective for harvesting firewood, processing larger logs, timber work and general estate or agricultural cutting duties.
It is a great option for professionals and serious landowners who want a saw with more authority than mid-range domestic machines, while still offering practical everyday usability.
Efficient Power with Lower Running Costs
The STIHL 2-MIX engine helps the MS 391 deliver excellent performance while reducing fuel use and emissions. STIHL’s four-channel technology improves combustion efficiency, while the compensator carburettor system helps maintain consistent engine performance even as the air filter becomes dirty over time. :contentReference[oaicite:1]{index=1}
This helps reduce maintenance interruptions and supports dependable day-to-day performance in tough working environments.
Easy Starting & Operator Comfort
The integrated manual decompression valve reduces the effort needed to start the saw, making it easier and more comfortable to get going. Once running, the STIHL anti-vibration system helps reduce fatigue by limiting vibration transfer into the handles during cutting. :contentReference[oaicite:2]{index=2}
This makes the MS 391 a more comfortable saw to use during longer cutting sessions, particularly when processing substantial volumes of timber or firewood.
Smarter Oil Management
The controlled-delivery oil pump and STIHL Ematic system help reduce unnecessary chain oil use while still ensuring the cutting attachment receives the lubrication it needs. This can help reduce running costs and improve efficiency, especially during regular use. :contentReference[oaicite:3]{index=3}
