Just my view ,, Been using chainsaws since 1990 ,, This is after less than 4 hours work on a clean filter . ,, It has good power to weight ratio ,, super responsive ,, One of the better chainsaws I have owned

The STIHL MS 500i is the world’s first chainsaw to feature electronically controlled fuel injection, and is a fantastic tool for cutting timber.

The MS 500i is also available in a version with heated handles. If needed, no-maintenance, wear-free heating strips can be added to the front and rear handles.

First ever chainsaw with STIHL Injection Technology. The best power-to-weight ratio on the market, and the simplest operation. Ideally suited for the harvesting and processing of large timber. All thanks to its unique lightweight design and outstanding acceleration. New bumper spikes, HD2 filter, captive nut on the sprocket cover for easy chain change, controlled-delivery oil pump, and tool-free fuel cap for safe and easy filling with fuels and lubricants. Where required, there is also the option of the MS 500i W variant with heated handles, which features no-maintenance, wear-free heating strips on the front and rear handles. These keep your hands warm, your grip strong, and operation safe in winter conditions
