The Stihl MS 382 is powered by a 72.2cc two-stroke engine that produces about 3.8–3.9 kW (around 5.3 HP), providing high cutting speed and strong torque for demanding cutting tasks.
It supports guide bars from about 20 to 25 inches, allowing the chainsaw to handle heavy logs and medium-to-large tree felling efficiently. The machine weighs about 6.2 kg (without bar and chain), offering a good balance between power and handling for professional use.
The chainsaw is equipped with several advanced features such as the STIHL QuickStop chain brake, which stops the chain immediately for safety, and a side-mounted chain tensioner that makes chain adjustments easier and safer. It also includes a decompression valve and ElastoStart system that reduce effort when starting the engine.
