The trackballs used for the Colour Grade, Mouse and DCP/Pixi Regions
are reasonably robust. They do not normally require much in the way of
maintenance. Over a period of time however, the trackballs can become
polluted from the general dirt and grease from the operators hands. On
each trackball, the rotation of the ball is transmitted to two shaft
encoders. Each of these encoders has a foam-plastic ring where it
touches the ball. If these foam rings start to degrade, they will need
replacement. It is fairly obvious how the encoders are removed and
replaced. The movement from the master ring, where fitted, is through a
plastic-edged wheel. If the edge ring is decayed, it will need
replacement. Again, it is fairly obvious how the ring is removed and
replaced.
The trackballs can be dismantled for cleaning purposes if necessary. Be
careful however as there are a lot of small parts such as ball bearings
that can fall out and get lost. Also note the shims that are in the
trackball casing. All these must be replaced during re-assembly or the
trackball will be hard to move.

The Panel Covers occasionally need cleaning to remove the general grease and grime from the surfaces. The best method for this is to use mild detergent and lukewarm water. Work this into the cover with a soft brush then wash off with water and allow the covers to dry thoroughly. Do not use any cleaning solvents as they can permanently damage the panel coating.
