Using the DeWalt DCH072B rotary hammer is quite straightforward. First, make sure you've got the right drill bit for the job and insert it into the keyless chuck. Then, if you're doing a job where dust is a concern, attach the DWH200D dust shroud and connect it to the DWH161D1 dust extractor to meet OSHA standards. When you start drilling, hold the tool firmly and apply steady pressure. For tasks like mounting struts or installing conduits, it's best to use it with lightweight masonry screw anchors. As for maintenance, after each use, clean the tool to remove dust and debris. Check the chuck regularly to ensure it's working properly. Keep the tool in a dry place, and don't forget that the battery and charger are sold separately, so handle them according to their own maintenance guidelines.
