Warranty Period: Typically 1 year, calculated from the date of acceptance. During this period, the manufacturer provides free repair or replacement of parts for malfunctions caused by manufacturing quality issues (vulnerable parts such as bearings and seals may be subject to separate agreements). The specific duration is subject to the purchase contract or the manufacturer's after-sales policy.
Design Service Life: Under normal maintenance and use conditions, the design service life of the main structure is typically 10-15 years. The actual service life depends heavily on the manufacturing materials, workmanship, and routine maintenance.
