Using the Bosch GBH18V-40CN rotary hammer is quite straightforward. First, if you haven't already, attach the auxiliary handle. Then, select the appropriate bit for your job and insert it into the chuck. You can choose between the rotary hammer and hammer-only modes according to your needs. The Vario-Lock feature allows you to adjust the chisel's angle for the best working position. When starting, use the Soft Start function, especially on softer materials like brick or tile. This will give you better control over the drilling or chiseling process. The lock-on / lock-off button is handy. In hammer mode, you can lock it on to keep the tool running continuously. And when locked off, it prevents accidental activation. The LED worklight is useful when working in dark areas, just turn it on to illuminate your workspace. As for the battery, make sure to use a CORE18V® High Power battery (sold separately) for optimal performance. When it comes to maintenance, after each use, clean the tool to remove dust and debris. Check the bits regularly for wear and replace them if necessary. Also, keep the anti-vibration system in good condition by making sure the air cushion in the hammer tube and the dampeners in the handle are intact. Remember, this tool comes with a five-year limited warranty. For more details, visit https://rb-pt.io/PowerToolWarranty or call 1-877-BOSCH99.
