We apologize for the inconvenience. Usually, the normal process of the manufacturer is to complete the delivery of spare parts within 7 to 15 working days, but during the period may be affected by external force majeure factors such as production and logistics. Unfortunately, since the platform does not participate in specific maintenance, it cannot directly assist you in checking the transportation of spare parts and site maintenance, and it is recommended that you can check the specific spare parts arrival date with the repair station personnel.
