Clean the two long shafts, the bearing and the rotary ball with clean soft dry cloth or paper.
3. Installing the trackball:
Put the trackball back in the trackball mechanism and align the clamping ring with the top cover
notches. Press the bulges on the ring with both hands and turn the washer 35° counterclockwise
until the washer clicks and locks. As the bulges are flush with the top cover, the ring is secured.
