How do I change the lid of the cool box?

To change the cover of the cooler box, please proceed as follows:

Use a screwdriver (preferably with a wide blade) to place between the lid and the edge of the cooler box near the tip of the hinge (see the arrow markings in the picture). If you carefully move the screwdriver a little bit, the hinge lock will come out of the hole on this side and you can remove the cover. The new cover can be mounted in the same way.
