Using your Bosch GBH18V - 26NK Rotary Hammer is straightforward. First, insert the appropriate SDS - plus bit into the chuck. Make sure it's locked in place. Then, attach the auxiliary handle for better control. If you're working in a dark area, turn on the LED worklight. Press the trigger gently for slow starts, thanks to the Electronic Precision Control feature. When drilling, keep the tool steady and let the impact energy do the work. Remember, the KickBack Control is there to protect you in case the tool gets stuck. As for maintenance, after each use, clean the tool to remove dust and debris. You can use a dry cloth or a soft brush. Check the chuck regularly to ensure it's in good condition. Also, make sure to use the tool with the right battery and don't overheat it to keep the Electronic Motor and Cell Protection working well. Store the tool in the provided carrying case when not in use. And if you're working in a dusty environment, consider using the optional GDE18V - 16 dust - extraction unit to keep the air clean and protect the tool.
