Using the Einhell TC - DH 43 Demolition Hammer is easy. First, make sure you've chosen the right chisel for the job - the pointed one is great for breaking hard materials, while the flat one is better for scraping or removing larger areas. Attach the chisel to the hammer using the SDS - Hex tool adapter. Adjust the additional handle to a comfortable position that suits your working angle. Plug it in using the three - metre power cable and you're ready to start. When using the hammer, hold it firmly with both hands and apply steady pressure. Don't try to force it too hard, as the 43 - joule impact strength will do most of the work. As for safety, always wear safety goggles and ear protection. Make sure the area you're working in is clear of people and obstacles. After use, unplug the hammer and store it in the provided transport and storage case. To keep it in good condition, clean the chisels regularly and check the power cable for any signs of damage. If you notice any issues, don't use the hammer and get it checked by a professional.
