Using the Petzl Croll L Chest Ascender is easy. First, make sure to pair it with either the BASIC ascender or the ASCENSION handled ascender for rope ascents. Attach a TORSE shoulder strap to the upper hole to keep the ascender in position, and note that the lower angled hole helps keep it flat. To open the catch, just pinch it. When using, ensure the rope diameter is between 8 and 13 mm. As for maintenance, after each use, check the ascender for any signs of wear or damage. If the ropes are dirty or frozen, the self - cleaning slot on the toothed cam will help keep it performing well. However, try to keep the ascender clean and dry. Store it in a cool, dry place to prevent the stainless - steel cam from corroding. And always double - check the certification and safety features before each use to ensure a safe ascent.
