4.4 Cleaning the inside of the spline shaft
Although depending on the air supply conditions and operating time, dust or grime adheres to the air path of
the spline shaft and may cause component pickup or mounting errors. The inside of the spline shaft should be
cleaned once every 3 months.

CAUTION
If spline shaft movement becomes unstable or abnormal noise is emitted from a spline shaft, then contact our sales
representative for assistance. Disassembly and cleaning of the spline shaft by the user will void the warranty.
4.4.1 Cleaning the inside of the spline shaft
1
Remove the nozzles from all heads.
With the nozzle station
1. Press the [Nozzle Change] button on the
[Unit] - [Head] screen.
2. Select "ALL" from the "Head Number" and
select "Store Nozzle" from the "Nozzle
Type" on the "Nozzle Change" screen.
3. Press the [OK] button to store all nozzles
in the nozzle station.
n
NOTE
If the machine is not equipped with a nozzle station,
remove all nozzles manually after opening the machine
safety cover. In case of the FNC nozzle, remove the

Prepare the cleaning kit (KV8-
M8860-00X).
1. Pour IPA (isopropyl alcohol) into the
container of the cleaning kit.
2. Slide the stopper on the nozzle tube of
the cleaning kit so it is positioned 185 to
200mm away from the nozzle tip.
3. Place a container or a cloth under the
head to be cleaned to receive IPA.

Clean the inside of each spline
shaft.
1. Insert the nozzle of the cleaning kit into
the spline shaft until the stopper on the
nozzle tube makes contact with the top
of the spline shaft.
2. Pour alcohol (IPA) into the spline shaft air
path to clean away dust and grime.

Blow air into the spline air path.
1. Insert the air hose into the fitting at the
top of the spline shaft to be cleaned.
2. Open the [Unit]-[Head] screen on the
operation display.
3. Press the [Blow] button on the operation
display to blow air into the spline air path
while placing cloth under the lower end
of the spline shaft.

CAUTION
Make sure to wear safety goggles as the exhaust
blowing air might strike face.
7
Repeat the above procedure.
Disconnect the air hose and repeat step 5
and then step 6.
When the IPA flowing out from the spline
shaft becomes clean, blow air through the
spline air path as the last cleaning step. Use
the same procedure to clean all other
heads.
8
Reconnect the air hoses back to
their original positions.
Return the nozzle to its original head if nozzle
was removed manually.

4.4.2 Checking the negative pressure
After cleaning the spline shafts, check the negative pressure.
1
After cleaning, check the vacuum
levels.
1. Leave nozzles detached from the heads.
2. Press the [Vacuum] button in the [Unit]
– [Head] screen to generate a negative
pressure, and read the value displayed in
“Maximum Value” of the screen.
Check the value is the standard value or
less in the open state as shown below.

2
Reattach the nozzles.
Return the ANC nozzles to the nozzle station,
and attach the FNC nozzles back to the
heads by referring to "2.2.4 Reassembling
the FNC nozzle assembly".

NOTE
The vacuum level in the spline shaft air path might sometimes differ slightly depending on the air source and operating
conditions. Use the above standard value for reference during maintenance.
Checking the vacuum level
Step 1
[Vacuum] button
Read "Max" values.
