Based on many years of service experience, we find that the problem of "warranty" has always been a big problem to our customers. Because customers are always worried about the maintenance unit after service, but just the general small maintenance department can not give customers a guaranteed warranty commitment.
In order to solve customers'worries, we make the following warranty commitments to customers:
1. Provide 12-month warranty service for all the gear reducers repaired (except as otherwise agreed in advance).
2. Within the warranty period, our company is responsible for free maintenance (except man-made failure) in case of original failure or re-damage of original parts.
3. There is no warranty if the machine is dismantled by itself or repaired by other units during the warranty period.
