2. Pay attention to handling and installation to avoid damage. I believe everyone knows that aluminum alloy is a soft material, so it may be deformed under strong impact, and its appearance may change under excessive impact. Therefore, attention should be paid to avoid bending when handling and using it.
3. Pay attention to cleaning easily damaged parts regularly. Moving parts, such as screws that need to be moved, need to be checked for damage, and they can be replaced and adjusted in time if they are worn.
