During my studies at the Hochschule Hannover - University of Applied Sciences and Arts I developed a concept chainsaw with interchangeable parts.

The ES 171 is a left-handed chainsaw and thus opens up a new market. It is also flexible in use by its interchangeable components. Through the quick chain release, the chain can be stretched off simple and convenient by the Rollomatic-Stretch-System.
