Introduction

This guide focusses on the Black&Decker GS720; the series number can be found on the sticker on the side of the product, next to the logo.

When the hedge trimmer is used extensively or in a wrong way, the blade can become blunt which makes the product useless. Replacing the blade without care can be dangerous, especially when handling sharp blades. This guide could also be used on how to remove the blade in case of maintenance.
