Setup, Compatibility & Care
To begin, ensure you have a compatible Makita 18V LXT lithium-ion battery. Insert the battery until it clicks into place. Before operation, select the appropriate SDS-plus drill or chisel bit and insert it into the one-touch slide chuck until it locks securely. To maintain the tool, keep the ventilation slots clear of dust and debris to prevent overheating. Periodically wipe down the body with a dry cloth and check the chuck for any residual masonry dust. Always store the tool in a cool, dry place and remove the battery when not in use to preserve terminal integrity.
