The Bosch AKE 40 S makes replacing and tensioning your saw chain very easy. It's equipped with an SDS system that allows you to do this with only one hand and without any tools. On top of that, this 1,800-watt electric chainsaw with its 40cm blade is equipped with Quick Stop, a rapid-reaction kick-back brake. Including its chain, the Bosch AKE 40 S only weighs 4.1 kilograms, so using it for a prolonged time shouldn't be a problem. The steel tines provide sturdiness and stability, and the robust construction makes for optimum durability.
