Post maintenance of newly installed garage door profiles can be divided into the following steps:
Step 1: Spray lubricating oil about the third year.
Step 2: Check the wearing parts such as roller wire rope in about the fifth year, and replace them if they are worn, rusted or damaged.
Step 3: Check whether the bearing in the steel wheel bracket is worn about the 7th year.
Step 4: Check the wear and balance of the balance system about the 8th year.
These accessories include: whether the garage door spring is broken and rusted, whether the steel wheel bracket is deformed, whether the steel wire rope is rusted, and whether the pipe inside the spring is deformed.
The so-called balance refers to whether a whole set of springs is kept level. If they are not kept level, it will lead to various difficulties and miscellaneous diseases. More than 80% of garage doors are caused by this problem.
