If the ratchet of your Xiaomi screwdriver isn't functioning properly, it could be due to several reasons. Here are steps you can take to troubleshoot the issue:
1. Check the ratchet mechanism for any debris or foreign objects that may be obstructing its movement. Clean the mechanism thoroughly with a brush or compressed air to remove any dirt or debris.
2. Check the screwdriver for any visible signs of damage, such as cracks or worn-out parts. If you notice any damage, it may be necessary to replace the affected components;
3. Applying a small amount of lubricant to the ratchet mechanism can sometimes help improve its functionality. Be sure to use a lubricant that is safe for use with tools and machinery;
4. Check if any screws on the screwdriver are loose, especially those that hold the ratchet mechanism in place. Tighten any loose screws to ensure that the ratchet operates correctly;
5. Sometimes, the issue may be with the screws themselves rather than the screwdriver. Try using the screwdriver with different screws to see if the problem persists.
If the above methods can’t solve the problem, please contact our local official service center or your seller for further assistance. They will help you in this regard.
