According to the information available, the product does not have an active motor brake. The saw blade runs out mechanically after switching off. A strong odour can be caused by carbon brushes, new components or high loads. This is normal for a short time. If the odour persists or smoke occurs, the product should no longer be operated. In this case, we will refer you to our Galaxus Assistant, which provides direct contact options so that you can be helped accordingly.
