Using the Petzl Tibloc Ascender is straightforward. First, make sure the rope you're using is between 8 to 11 mm. Clip the ascender onto the rope and attach a compatible Petzl carabiner (not the SPIRIT). The automatic system will start the braking action when needed. When using it in a hauling system, it acts as a great progress capture device. As for maintenance, keep it clean, especially after use in muddy or icy conditions. The self - cleaning slot helps, but you can also use a soft brush to remove dirt. Store it in a dry place. Always check the ascender for any signs of wear before each use. If there are any issues, don't use it and contact a professional for inspection.
