3.2 Cleaning and lubricating 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 6 months.
3.2.1 Cleaning the inside of the spline shaft
1
Remove the nozzles from all heads.
After making sure that the emergency stop
button is pressed, remove all nozzles.
On standard heads and YG100RB precision
heads (roller lock clamp heads): Remove
the nozzles by hand.
On YG100RA FNC heads: Remove the FNC
nozzle assemblies by referring to section
1.2.1, "Removing FNC nozzle assembly"
earlier in this chapter.
2
Disconnect the air tube from each
spline shaft.
As shown in the photo, disconnect the air
tube inserted into the fitting at the top of
each spline shaft.

3
Prepare the cleaning kit (KV8-
M8860-00X).
1. Pour IPA (isopropyl alcohol) into the
container of the cleaning kit. (Never pour
other solvent into the container.)
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 paper cup or tray under the
spline shaft to be cleaned. (This prevents
IPA from flowing out downwards in step
4.)

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 tube into the fitting at the
top of the spline shaft to be cleaned.
2. Open the [Unit]-[Head] tab 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.

6
Repeat the above procedure.
Disconnect the air tube and repeat step 4
and then step 5.
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.
7
Reconnect the air tube to each
spline shaft and reattach all
nozzles.

3.2.2 Lubricating the slide section and checking the negative pressure
After cleaning the spline shafts, lubricate the buffing parts (slide sections) and check the negative pressure
levels (vacuum levels).
1
Lubricate the following parts.
Lubricating oil has been cleaned away by
IPA cleaning, so lubricate the following
parts.
Prepare the oil syringe applicator (KV8-
M8870-00X) filled with turbine oil (VG32).
1. Standard heads and YG100RB precision
heads: Apply one drop of oil at the
elongate holes at the joint between the
nozzle holder and the spline shaft. (2
locations for each spline shaft) After
applying the oil, move the nozzle holder
up and down several times.
2. FNC heads: Pull down the FNC index
holder, and you will see two small cams
on the FNC spline shaft. Apply one drop
of oil at each cam and then move it up
and down by hand several times.
53368-F9-00
2
Remove excess oil.
Using the air blow gun, blow air for about 5
seconds from the bottom of the spline shaft.
Then open the [Unit]-[Head] tab screen and
press the [Blow] button to blow air through
the spline shaft.
NOTE
A thin coat of oil is enough to lubricate the slide section.
3
Check that the oil was removed.
Blow air through the spline shaft again while
using commercially-available oil blotting
paper, and check for residual oil in the spline
shaft.

4
Install the FNC nozzle assemblies.
Reassemble all FNC nozzle assemblies
(YG100RA) by referring to section 1.2.4,
"Reassembling the FNC nozzle assembly" in
this chapter.

Checking for residual oil

Oil will appear after blowing air (first
time) for about 5 seconds from the
nozzle tip.
Repeat the air blow for about 5
seconds each from the nozzle tip
and from the attachment side.
This task is finished when oil no
longer appears.
