If not, the bearings will be worn and the life will be shortened, The methods of maintenance are as follows: oiling once for each shift. It should be noticed that the oil channel must be cleaned immediately if the oil is not be consumed or the loss is slow then 50# motor oil should be added. The oil cup is placed on the upper end of principal axis. Each shift should add 3# lithium base grease once with grease gun on bearing of principal axis base and bearing of milling roller. Disconnect and clean the analyzer once for 6 months and apply 3# lithium base grease. Apply lithium base grease for bearing room.(see lubrication system for details).
