Standard coverage
Main product warranty terms are confirmed in the final quotation or invoice. Wear parts, misuse, impact damage and unauthorized modification are not normally covered.
After-sales
Warranty Policy
Warranty handling is based on the confirmed product model, purchase record, use environment and issue diagnosis.
Diagnosis process
Customers should provide order number, product model, photos, video and a clear issue description so the team can identify the cause.
Commercial fleets
Rental fleets and distributors should keep operating records and maintenance notes to support faster after-sales handling.
