3.2 Cleaning 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 6 months.
3.2.1 Removing the standard nozzles
1
Remove the standard nozzles from
the head.
After checking that the emergency stop
button is pressed, remove the standard
nozzles attached to Heads 1, 3 and 5 of the
"F" type machines by hand or all heads
(Heads 1 to 6) of the "S" type machines.

2
Remove the FNC nozzle assemblies
from the head.
By referring to the previous section "1.2.1
Removing the FNC nozzle assembly", remove
all FNC nozzle assemblies from the head.
3.2.2 Cleaning the spline shaft
1
Remove the plug bolts for spline
shaft maintenance.
There are 6 bolts used to plug the cleaning
hole of each spline shaft on the rear side of
the blow valves of the head assembly. Use
the M5 hex wrench to remove all plug bolts
for Heads 1 through 6.

2
Prepare the cleaning tool (KV8-
M8860-00X).
1. Pour IPA (isopropyl alcohol) into the
container of the cleaning tool. (Never
pour other solvent into the container.)
2. Slide the stopper on the nozzle tube of
the cleaning tool so it is positioned 110 to
150mm away from the nozzle tip.
3. Place a paper cup or tray under the
spline shaft to be cleaned. (This prevents
IPA from flowing out downwards.)

Clean the inside of each spline
shaft.
1. Insert the nozzle of the cleaning tool 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

4
Blow air through the standard
spline air path.
Use the air blow gun and IPA to clean the
spline shaft air path of Heads 1, 3 and 5 of
the "F" type machines or all heads of the "S"
type machines.
1. Connect a 4mm diameter air tube
(200mm long) to the air blow gun
(KU4-M8590-00X) via a joint ($US4).
2. Insert the air tube connected to the air
blow gun into the cleaning hole from the
above, and blow air through the spline
shaft while placing cloth under the lower
end of the spline shaft to prevent the
remaining IPA from splattering.
3. Repeat step 3 to clean the inside of the
spline shaft and then blow air through it
again.
4. Next, fit the air tube connected to the air
blow gun to the tip of the nozzle holder,
and blow air through the spline shaft
from the bottom while lightly placing
cloth over the cleaning hole.
5. Repeat the above process a few times
until the IPA flowing out from the spline
shaft is clean.

Blow air through the FNC spline air
path.
Use the air blow gun and IPA to clean the
spline shaft air path of Heads 2, 4 and 6 of
the "F" type machines .
1. As in step 4, connect a 4mm diameter air
tube (200mm long) to the air blow gun
(KU4-M8590-00X) via a joint ($US4).
2. Insert the air tube connected to the air
blow gun into the cleaning hole from the
above, and blow air through the spline
shaft from the top to bottom, while
placing cloth under the lower end of the
spline shaft to prevent the remaining IPA
from splattering.
3. Repeat step 3 to clean the inside of the
spline shaft and then blow air through it
again.
4. Next, place the air tube of the air blow
gun against the air path hole at the tip
of the FNC lock pin. At this point,
removing the joint from the air blow gun
and using the short sir tube originally
attached to the air blow gun would
make it easier to do this work.
5. Blow air through the spline shaft from the
bottom while lightly placing cloth over
the cleaning hole.
6. Repeat the above process a few times
until the IPA flowing out from the spline
shaft is clean.

Reattach the plug bolts into the
cleaning holes.
Use the M5 hex wrench to screw the 6 bolts
back into the cleaning holes to plug them.
