Do not apply strong force or shock to the camera unit and lighting unit during cleaning. Optical axis adjustment might

become unreliable.

CAUTION

If trouble occurs with the lighting unit, then contact YAMAHA sales representative. Disassembly and cleaning of the

lighting unit by the user will void the warranty.

5.3 Cleaning and lubricating the W-axis

Every six months, cleaning and lubrication of the ball screw, guide, and hex spline of W axis are necessary. For

lubrication locations, see "Chapter 5 Lubrication points and schedule". For lubrication of the dual stage W2

axis (U axis), see "4.8 Dual stage only: Cleaning and lubrication of U axis (W2 axis)" in this chapter.

Change the conveyor width to its

maximum width.

1. Press the [Conveyor Width] button on the

[Unit] – [Conveyor] screen to display the

“Conveyor Width” screen.

2. Enter the maximum value of the

conveyor width in the “Changed

conveyor width”, press [OK]. The

conveyor is changed to the width that

was just entered.

54318-L2-00

TIP

The maximum value of the conveyor width is 460 mm

for the single lane and dual stage speciﬁcations. In

case of the dual lane speciﬁcation, the maximum value

of the conveyor width in one side lane is 382 mm. Enter

382 mm on lane 1.

(For dual stage specification only)

Move the stage 2 up.

1. Push the [Stage 2] - [Pushup] button to
