Page 21: Maintenance
Maintenance Used correctly, the machine is an extremely low-main- tenance and reliable. This section covers the general maintenance items that need attention on a periodic basis. There are three main mechanical items to check: 1. Grinding Heads. 2. Planetary drive system. 3. - Page 22 Spring Steel Heads The below diagrams illustrate the main parts comprising this type of grinding head. Diagram 1 1. Spring steel spring 2. Head plate 3. Cushion ring 4. Head mate Diagram 1. Spring Steel Head Diagram 2 1. Spring steel springs 2.
- Page 23 Grinding Heads Drive System The grinder comes equipped with Dual Drive Technolo- gy™. As the grinding discs are driven by the large mo- tor via an internal belt, and because the belt is sealed inside the machine, there is no maintenance regarding this drive system until a major service (belt and bearing replacement) is due.
