Using this DeWalt dust extractor is easy. First, attach the hose to the dust extractor telescope. Then, connect the dust extractor to your SDS rotary hammer. When you start using the hammer, the dust extractor will start collecting the dust. Make sure the connection between the hose and the tools is tight to ensure efficient dust collection. When not in use, store the dust extractor in a dry place. Regularly clean the dust container to keep it working well. Also, check the hose for any blockages or damages and replace it if necessary.
