System Maintenance 17-3
Cleaning the trackball
Tools: Paper, dry cloth or mild soapy water
Method:
1. Disassembling the trackball:
Press the bulges on the clamping ring by both hands and turn the ring about 45°
counterclockwise until it lifts. Take out the ring and the rotary ball. Be careful not to drop the
ball. As shown in figure below.
2. Cleaning
Clean the two long shafts, the bearing and the rotary ball with clean soft dry cloth or paper.
3. Installing the trackball
Put the rotary ball back in the trackball mechanism and put the clamping ring back in (with the
bulge direction of 15 ° deviated from the horizontal line), turn the ring clockwise until the
bulges are flush with the top cover, and the ring clicks and locks, which means the ring is
secured. See figure below.
