MOTION PICTURE PROJECTION 691 Note: Refill the grease cups with Transverter grease only, as other kinds of grease will be likely to injure the highly polished steel balls and surfaces of the bearings. Troubles and Remedies If the brushes are not replaced as explained above, the commutator may become blackened and require attention either by the application of a stone, or, in severe cases, it may require the removal of the armature so as to turn the commutator in a lathe. Should the bearings become dry or an improper lubricant be used, it may cause the destruction of a bearing and require its replacement. In case it is necessary to have any repair parts or supplies, order these direct from the factory, giving the serial number on the name plate of the machine.
