Bosch GBH18V-40CK27 18V PROFACTOR 1-5/8 SDS-max Rotary Hammer w/ (2) 12.0 Ah CORE Exclusive Battery

Using the Bosch GBH18V-40CK27 is quite straightforward. First, make sure the battery is fully charged. Insert the battery into the hammer. If you're going to drill, choose the right bit and insert it into the keyless chuck. You can adjust the rpm and bpm settings using the soft start feature, especially when working on softer materials like brick or tile. When chiseling, use the Vario - Lock to set the chisel at the best angle. Hold the auxiliary handle firmly for better control. As for safety, always wear appropriate safety gear like goggles and gloves. Don't use the tool in wet conditions. Avoid overloading the tool; if it starts to bind, stop immediately to prevent kick - back. For maintenance, after each use, clean the tool with a dry cloth. Check the battery regularly and charge it properly. If you're not going to use the tool for a long time, store it in the carrying case in a dry place. The charger should be kept in a well - ventilated area to avoid overheating.
