Method:
1. Disassembling the trackball:
Press the bulges on the clamping ring using both hands and turn the ring about 35°
clockwise until it lifts. Take out the ring and the rotary ball. Be careful not to drop the
ball. See the figure below.
2. Cleaning
Clean the two long shafts, the bearing and the rotary ball with a 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.
Turn the ring counterclockwise until the bulges are flush with the top cover and the
ring clicks and locks, meaning the ring is secured. See the figure below.
