DONGHAI SM 750/750 A
CHINESE MANUAL Type I.
Several years ago a man named Clay Jones had a motorcycle club in Shanghai and had a site about the Donghai. Unfortunately, Clay is no longer with us and the site has disappeared. After a lot of searching I found it in an internet archive. There I managed to download as much information as possible, including a manual from 1977. I have edited the photos as much as possible and hope that the order is correct. Its a Type I.

And here is a partsmanual about the Type II.
The Donghai 750 three-wheeled motorcycle is a new product developed in recent years. It has been put into mass production and is provided for social use. In order for users and related personnel to be better familiar with the general structure and structure of the motorcycle, Assembly status, and also for the user's need to equip spare parts in the future, this catalog is specially compiled.

l. This catalog is compiled based on the production drawings and relevant technical documents of the wood factory in March 1973. Due to the continuous improvement of products, if the products shipped from the factory in the future may differ from this catalog, the product drawings and technical documents of the wood factory shall prevail.

2. When this catalog is laid out on the same drawing, symmetrical or identical parts only represent one; the others are omitted, but the quantity indicated in the quantity column in the table is the total quantity used in this drawing.

3. The numbers on the drawings, if there are ????, they are component numbers.

4. Use this in the figure number column in the table. Those with numbers such as "National Standard", "Ministry Standard", "Enterprise Standard", etc. are all accurate and are not produced or supplied by our factory. For major collaborative parts, please indicate the name of the collaborating factory in each column below the form to facilitate user contact.

5. When users and relevant personnel refer to this catalog, if they know the shape of another component, they can first find the component on the drawing, and then use the serial number on the drawing to find the drawing of the component in the corresponding table. number and name. Users can write only the drawing number but not the name when writing to purchase, but do not write only the name but not the drawing number.

6. Due to the tight compilation time and lack of experience in this catalog, it is inevitable that there will be some errors. We hope that users and relevant personnel will correct them in future practice.
