Warranty Policy
All units we sold are provided with a warranty period of no less than one (1) year since the unit installation date. The specific warranty period is different according to specific contracts based on different closing prices. All products serial numbers and other information is saved into our computer management system.



During the warranty period, if distributors/users claim that parts is damaged due to product quality defects, the damaged parts must be returned to our authorized Spare Parts Center, our engineers will check and analyze the damaging reasons, if the parts damage is due to quality defect, we’ll send the original parts to the distributor/user for replacement free of charge. If the parts damage is due to un-proper operation and/or traffic accidents, the distributor/user need to pay for the parts costs.

Malicious behavior to cheat for original parts will be put into the company’s black-name list.
