Review STIHL Chainsaw

The STIHL MS391 and MS391P chainsaws are powerful and efficient tools designed for professional logging and heavy-duty cutting tasks. These saws are part of STIHL's M-Series, which is renowned for its high performance and ease of use.

The MS391 and MS391P chainsaws are equipped with a 3.5 HP (2.6 kW) two-stroke engine that delivers excellent power and torque for demanding cutting applications. The engine features a side-accessible air filter, making it easy to maintain and clean. The saws also come with an advanced intake system, which ensures optimal air flow and efficient combustion.

Both models have a generous 16-inch (45 cm) bar length and a STIHL Quickchain (Q) bucking, which ensures easy chain adjustment and reduces the time spent on maintenance. The saws also come with a STIHL ElastoStart starter handle that reduces the effort required to start the engine.

The MS391 and MS391P chainsaws have a number of features designed to enhance operator comfort and safety. These include a low-vibration handle system, a large fuel tank with a capacity of 20.6 oz (600 ml), and a decompression valve that makes starting the saw easier, especially when the engine is cold. Additionally, the saws come with a chain brake that activates automatically in case of kickback, providing an added layer of safety.

The MS391P model comes with a pre-separator air filtration system, which effectively reduces the amount of emissions and improves the saw's overall performance. This makes it an excellent choice for operators working in sensitive environments or those looking to reduce their carbon footprint.

Both the MS391 and MS391P chainsaws are designed to be durable and long-lasting, with high-quality components and a robust design. They are also easy to maneuver, thanks to their lightweight construction and well-balanced design. Overall, the STIHL MS391 and MS391P chainsaws are powerful, efficient, and versatile tools that are ideal for professional logging and heavy-duty cutting tasks.
