Preparation (structural engineer) → countersignature (electronic control, domestic sale/export market support)
1.
→ approval (development leader)
2.
For products of any development level, the process must be started to output the maintenance manual
3.
The preparation purpose of the Manual is to guide the market maintenance after the new product is launched,
and the using objects are pre-sales and after-sales maintenance outlets.
Pre-sales disposal of defective products by the agent: Including product packaging, appearance, structure,
performance fault
Consumer after-sales service maintenance: Mostly product appearance, structure, performance fault
4.
The mobility of market service outlets and personnel is higher, and even the maintenance personnel have never
contacted the products in the earlier stage and completely rely on the Manual in the process, so the accuracy and
completeness of the information must be ensured.
5.
When the PLM process of the Maintenance Manual is started, please attach the following decryption annexes, as
shown at right:
Manual PDF documents (Daily Maintenance Manual + Quick Start Manual, or Operating Instruction)
Exploded view PDF documents + Exploded view source file (source file format: dwg or svg)
