The STIHL MS 500i is designed and built exclusively for forestry personnel and tree service professionals who need a saw that can move efficiently through demanding work. As the first chainsaw on the worldwide market with electronically controlled fuel injection, it combines rapid acceleration with an exceptional power-to-weight ratio, helping operators stay productive when felling, bucking, and delimbing. Lightweight and responsive, it delivers the kind of handling that helps make long days in the woods more efficient.
At the heart of the MS 500i is a unique fuel injection system with sensor-controlled fuel metering that helps deliver optimum performance across operating conditions. An ES Light guide bar reduces weight at the cutting end of the saw for enhanced maneuverability, while the HD2 air filter allows for longer run times between cleanings. The result is a professional chainsaw that balances cutting performance, responsiveness, and efficiency in a package built for serious forestry work.

Note: STIHL recommends use of fuel with no more than 10% Ethanol content. Using fuel with greater than 10% Ethanol content may cause damage to your equipment and may void your STIHL warranty.
