The following describes the cleaning and lubrication procedure of W-axis of YSM20R single-lane type as
example. As to YSM20WR Single-lane type (for transferring heavy board), the W-axis cleaning and lubrication
procedures are the same, though the mounting position of hexagon spline shaft and the height of guide flame
deffer from the normal type.
