Mainentance: Mat: The top surface of the mat can be cleaned using a roller textile cleaner. Bearing: Oil in the bearing will last for 3-4 years or more. Running the bearing without oil will do no harm due to the choice of materials and type of construction. Oil should be added if the top reservoir (with ruby ball ) is totally dry. The oil level will be below the ruby ball as, when the subplatter is lowered onto the shaft, the bearing surface increases the level of oil above the ruby ball. When the subplatter is removed you can see the level of oil inside its sliding ring ( brown colour). If it is above the sliding ring in the subplatter, there is plenty of oil. If excess oil is added it will run into the appropriate extra reservoir. Belts: Periodically remove the platter and remove the belts. Clean belts and running surfaces of the motor pulleys and the subplatter with a soft cloth soaked in alcohol (every 8-12 months). For best performance replace belts every three years. VTA Guage: The sign 'B' in the top left corner of the clock indicates that the battery should be replaced. Remove the battery cap by turning it counterclockwise with a coin and remove old battery replacing with a new battery with the + side facing up. Secure the battery cap. Immediately after the battery has been set, a meaningless display or 'E' will appear. This is quite normal so merely continue to set up 'origin' again.
