4. Loosen the mounting bolts shown in the figure below, then adjust the lever height until there is a 1.9 mm gap (use a thickness gauge) between the bottom of the mechanical valve and the lever. At this stage, the spring…
1.11.2 Valve Switching Lever Height Adjustment
This adjustment should be performed on the reference head after completing
adjustments to the vertical movement of the nozzle. (Refer to 1.10 “Nozzle Vertical
Movement During Placement” for details.)
The reference head can be identified by its height. All heads are measured with spools
lifted, and the lowest one is referred to as the reference head.
1. Press the EMERGENCY STOP button to take the 200V down to 100V.
WARNING
• Always be sure to cut off the 200V power before carrying
out any work.
• Exercise extreme caution when working on the machine if
the cam is not at its origin (0 deg.). Recoil of the cam
axis can endanger the operator.
2. Set the cam angle to 0°, then activate the place solenoid (Y035 ST9 PLACE SOL
ENGAGED) at station 9 to work the lever.
3. Use the cam handle to rotate the cam to 180°.

4. Loosen the mounting bolts shown in the figure below, then adjust the lever height
until there is a 1.9 mm gap (use a thickness gauge) between the bottom of the
mechanical valve and the lever. At this stage, the spring pusher is pressed down
0.1 mm.
Note: Do not touch the speed regulator.
The blow air pressure is set to 15.0 ± 0.5 kPa (13st: 7.0 ± 0.5 kPa). The user should not
change the setting, as a manometer is required for the adjustment.

1.12 Reverse-theta Mechanism (Station 10)
Point
This mechanism reverses the nozzle rotation which occurred at the station 9 part
placement. The nozzle is returned from that part placement angle by the amount of
rotation which occurred at stations 2 and 8.
1.12.1 Clutch Meshing Check
Perform this check on the low-pressure nozzle.
Note: The low-pressure nozzle refers to the placing head (out of the 16) that receives the weakest
pushing pressure. Use the low-pressure nozzle for meshing checks at stations 2, 8 and 10.
1. Press the EMERGENCY STOP button to take the 200V down to 100V.
WARNING
• Always be sure to cut off the 200V power before carrying
out any work.
• Exercise extreme caution when working on the machine if
the cam is not at its origin (0 deg.). Recoil of the cam
axis can endanger the operator.
2. Set the cam angle to 0 degrees, then turn the station 10 solenoid valve on to work
the cam lever.
3. Set the dial gauge to the bottom of the nozzle shaft brake.
4. Use the cam handle to rotate the cam to 200°.
5. Ensure that the clutches mesh properly and the placing head assembly deflects the
dial gauge by 0.30 ~ 0.35 mm as illustrated below.
