5.3 Cleaning and lubricating W-axis
Cleaning and lubricating the ball screw, guide, and hexagon spline of W-axis and U-axis (for YSM20R dual-
stage type) are required once a year. See "Chapter 5 Lubrication points" for details about lubrication points.
Note that the lubrication procedure differs among YSM20R Dual-stage type, YSM20R/YSM20WR Single-lane
type, and YSM20WR Dual-lane type. The following describes each lubrication procedure.
5.3.1 YSM20R Dual-stage: Cleaning and lubricating W/U axes
The following describes the cleaning and lubrication procedure of W-axis and U-axis of YSM20R dual-stage type.
1

TIP
The push-up units of both stage 1 and 2 can be moved
by reading the board data.
2
Change the conveyor width to the
minimum width.
1. Press the [Width] button on the [Unit]
- [Conveyor] screen to display the
"Conveyor Width" screen.
2. Enter the minimum conveyor width "50
mm" in the "Target Width" box and press
the [OK] button. The conveyor width is
changed to the specified width.
3
Raise the push-up unit.
1. Press the [Push Up] button to display the

is over 380 mm, the [Push Up] button on the upstream is
grayed out. If raising the push-up unit of downstream,
that of upstream is also raised.
n
NOTE
It is convenient to access to the U-axis guide and ball
