Solution:
In order to increase the service life of the Massage Gun and improve the performance of the product, Xiaomi Massage Gun adopts the oil storage tank design scheme. Each machine has undergone a 1.5H load aging test in the factory. Lubricating oil is added twice before packaging, and the machine is used before starting to use. A few times, there may be oil leakage, which will not cause any impact on the machine, just wipe the excess oil with a rag.
