Using the DeWalt DCH273H1 Rotary Hammer is a breeze. First, make sure the battery is fully charged. Insert the battery into the hammer and you're ready to go. Use the rotating dial to select the mode you need - drill, hammer drill, or chip. When drilling in concrete, hold the hammer firmly and let the 2.1 joules of impact energy do the work. If you're using it for a long time, the SHOCKS Active Vibration Control System will help reduce the vibration you feel. When using it with the DWH303DH On Board Extractor, it meets OSHA Table 1 standards, so you can work safely. As for maintenance, keep the tool clean after each use. Wipe it down with a dry cloth. Check the battery regularly. The 3-LED fuel gauge on the battery makes it easy to see the charge status. Store the tool in the hard case when not in use to protect it from damage. The battery has a non - marring over - molded rubber base, which also helps protect finished surfaces. Just follow these simple steps, and your DeWalt DCH273H1 will serve you well for a long time.
