Maintenance of roller skates
1. Often remove and wash the inner sleeve of shoes, which can prevent odor and bacteria.
2. Changing the wheels on the left and right sides often makes the wheels of skates more durable.
3. Avoiding sliding on rough roads can prolong the service life of wheels and bearings.
4. Do not replace wheels or bearings individually, which will reduce the stability of sliding.
5. If the bearing has been used for a long time, when the sliding is not smooth or there is a "sand" sound, the bearing can be removed and immersed in the "de-impregnated oil" for about half an hour, the impurities in the bearing will be cleaned out, and then sprayed with engine oil or special bearing oil. This can extend the service life of bearings.
6. When products are not in use, they should be stored in dry and sunless places. This has a certain effect on preventing rust of fittings and aging of products.
