List of Maintenance Services
| Service name | Service content | ||
| Purchasing parts | We will reply quickly for quotation and delivery based on the information regarding model name and serial number of the blower. | ||
| Proposing maintenance plans | Based on the results of disassembling, we will indicate the maintenance details with emphasis on “extending equipment life”, “avoiding accident risk” and “minimizing maintenance cost”. | ||
| Maintenance (Overhaul) | Please refer to the Table listed below (standard overhaul inspection content) | ||
| Simple inspection | Please refer to the Table listed below (Simple inspection) | ||
| Emergency services | Each sales branch office will respond to emergency call and dispatch a technician to users’ site in case it is necessary and feasible. | ||
| Dispatch of Supervisor | It is not impossible to provide guidance of working instruction at users’ site in case customers would operate the maintenance by themselves. But we cannot guarantee the outcome if our technician did not work it directly. | ||
