> **Please note:** CEMOTO currently publishes a **single shared owner manual covering the D-series** (D02 and D03). It is listed on the store as separate D02 and D03 entries, and both files cover the same D-series content: safety and prevention, assembly, start and run, display, fault display, settings, maintenance, troubleshooting and warranty.

The D-series manual is an illustrated 28-page document. Because the pages are image-based, the text below summarizes its contents so you can search it.

## Reading the manual on an image-based PDF

The D-series PDF is a scanned/illustrated document, so text search and copy-paste do not work reliably. Two practical options:

1. **Use this documentation center**, which reproduces the text content in searchable form.
2. **Use the assembly and technical videos** — see [Technical Guides](https://help.cemotoride.com/link/336).
