Effective after-sales service for organic fertilizer disk granualtor machines should focus on four core areas: rapid response, full-cycle maintenance, technical empowerment, and spare parts guarantee, forming a standardized service closed loop that balances stable equipment operation and customer production efficiency.  The specific implementation is as follows:

1. Full-Process Response System: Establish a 7×24-hour customer service and technical support channel, providing quick online answers to operation and troubleshooting questions.  After-sales engineers will be dispatched from the nearest location, arriving within 24 hours in the province and 48 hours outside the province. Emergency faults will be prioritized to minimize production downtime.

2. Layered Maintenance Services: The fertilizer manchine manufactuer should provide free installation and commissioning + on-site operation training.  On-site inspections will be conducted 1, 3, and 6 months after delivery to check key components such as disc inclination, rotation speed, liner wear, and the spraying system. Customized annual maintenance plans will be provided, including regular replacement of wear parts and parameter calibration to prevent future malfunctions.

3. Dedicated Wear Parts Guarantee:  Maintain sufficient stock of core wear parts such as disc liners, scrapers, bearings, and atomizing nozzles, and establish regional spare parts warehouses for direct shipment. Long-term customers will receive discounts and free delivery of wear parts, ensuring timely replacement.

4. Technical and Training Empowerment: Provide customers with equipment operation, daily maintenance, and simple troubleshooting manuals (text, images, and videos). Regularly organize online/offline technical training to teach staff basic maintenance skills and reduce future reliance on external support. Establish customer files to record equipment operation, maintenance, and fault information, enabling full life-cycle traceability.

5. Value-Added and Extended Warranty Services: After the warranty period, provide flexible extended warranty plans covering on-site repair, parts replacement, and technical upgrades. For older equipment, provide modification and upgrade services to adapt to increased production capacity and process optimization needs, extending equipment lifespan.
