Maintenance of the trolley case:
1. The vertical tour box should be placed upright without any pressure on it.
2. The freight sticker on the tour box should be removed as soon as possible.
3. When not in use, cover the tour box with a plastic bag to avoid dust. If the accumulated dust enters the surface fibers, it will be difficult to sort it out in the future.
4. The cleaning method depends on the raw materials. If the boxes of ABS and PC raw materials are soiled, they can be wiped with a damp cloth dipped in a neutral detergent, and the dirt will be removed soon. However, EVA is not applicable. The EVA box surface can be brushed off with a brush first. If the stain is enlarged, it can also be cleaned quietly with a spot of scouring oil. The wheels at the bottom of the box should always be lubricated with oil.
5. The wheels at the bottom of the box should be kept smooth, and it is necessary to add lubricating oil to the axle when storing after use to prevent rust.
