2.2.2 Cleaning and lubricating the Y-axis guide
1
Prepare for the cleaning and greasing.
e
1. Press the emergency stop button to open the machine safety cover.
2.
Place a square cloth under the head unit
.
2
Clean the guide.
1. Grasp the carrying handle and move the
head unit backward.
2. Using a paper cloth (clean room type)
which produces no lint, wipe the old
grease and soiling from the entire guide.
3. Move the head unit to the opposite side,
then clean the opposite-side guide.

3
Inject the grease.
Using a grease gun (bend type), inject the
prescribed grease (NSL) at the 4 grease
nipples (2 each nipples for the left and right)
for the Y-axis guide.

4
Spread the grease.
Grasp the carrying handle and move the
head unit front and rear several times
manually to spread the grease.
n
NOTE
The grease injected through the nipple oozes to the
guide when moving the axis.
5
Wipe off the excess grease.
Wipe off the excess grease from both ends
of the guide.
6
Inject the grease again.
Repeat Steps 3 to 5 twice again.
After that, visually check that the grease is
applied to the entire guide.
7
Perform a warm-up.
1. Remove the square cloth.
2. Close the machine safety cover and
cancel the emergency stop.
3. Press the [Warm Up] button on the
"Setup" screen to open the "Warm Up"
screen. Perform the warm-up operation
for approx. 8 minutes.

8
Check the grease condition.
1. After stopping the warm-up, press the
emergency stop button to open the
machine safety cover.
2. Wipe off grease which has collected on
the guide end faces.
c
CAUTION
Repeat Steps 7 and 8 until grease accumulations no
longer occur. Beginning production with grease
accumulations present could cause the grease to splatter.

2.3 Conveyor
2.3.1 Checking the conveyor sensor condition and operation
This machine uses a transmission type fiber sensor as the conveyor sensor.
As the conveyor width changes, the distance between the light emitting and light receiving sensors also
changes. Accordingly, the light receiving status of the sensor may change.
Therefore, a conveyor sensor tuning function is provided on this machine that stores the sensor light receiving
status after the conveyor rail width has been changed and automatically rewrites the sensor threshold value.
By changing the conveyor rail width periodically, you can check that the conveyor sensors and conveyor sensor
tuning operate correctly.

1
Prepare for work.
Check that there is no board on the
conveyor and that there is no push-up pin in
the conveyor movement range.
2
Change the conveyor width.
1. Open the [Unit] - [Conveyor] screen.
2. Press the [Width] button.
3. Enter the desired conveyor width and
press the [OK] button. The conveyor
width is changed to the specified width.

3
Check that no error occurs.
When no error message appears after the
conveyor width has been changed, the
conveyor sensors operate correctly. So, no
further check is needed.
If an error occurred, perform "Conveyor sensor tuning" from Step 4.
Step2
[Width] button Enter desired conveyor width.

Perform the conveyor sensor
tuning.
1. If an error occurred, press the [Sensor
Tune] button on the right of the [Unit] -
[Conveyor] tab screen.
2. If pressing the [OK] button on the
confirmation screen, the threshold value
is calculated as the current sensor status
is no board.
54302-KMG-00
5
Check the sensor status.
Change the conveyor width again and
check that no error message appears.
6
Check the portion around the
sensor.
If the error message still appears, the light
receiving status around the sensor may be
poor, the sensor (amplifier) may be
malfunction, or the fiber may be broken.
First, remove contaminant or dust from the
sensor, then perform the conveyor sensor
tuning again.
