e
1
Detach nozzles.
1. Press the emergency stop button and open
the machine safety cover.
2. Detach nozzle from the head.
When the nozzle station is equipped.
2. Store the nozzles and detach the whole
nozzle holder.
3. Open the nozzle station shutter and detach
nozzles.
2
Clean the slide section.
Apply absolute ethanol to the slide section.
Push the nozzle tip several times to repeat the
buffing action (spring action) to clean the slide
section. After cleaning, blow the air to remove
absolute ethanol.
3
Lubricate the slide section.
Using a precision screwdriver or similar tool
with a pointed tip, apply a small amount of
turbine oil (just enough so that it sinks in) to the
slide section.
4
Check the nozzle spring action.
1. Press on the nozzle tip several times to
spread turbine oil with a plate or similar.
2. Wipe away excess oil from around the
nozzle using lint-free cloth.
5
Remove excess oil remaining in the
nozzle.
1. Air blow with the air blow tool for about 5
seconds from the nozzle tip side, and about
5 seconds from the nozzle mounting side.
2. Repeat this process a few times to remove
excess turbine oil remaining in the nozzle.
n
NOTE
A thin coat of oil is enough to lubricate the slide section.
6
Check that the oil is removed.
Use a commercial oil-blotting paper to check
the residual oil inside nozzle if necessary.
n
NOTE
Performing step 5 is usually sufficient to remove oil
remaining in the nozzle. However, if oil still remains, blow
air through the nozzle once again.
7
Return nozzles to original positions.
1. Check again that no oil remains in the
nozzle.
2. Return the nozzle to the original head.
When the nozzle was removed from nozzle
holder, store it its original place and return
to nozzle station.

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.

2. Detach nozzles from the head.
When the nozzle station is equipped.
2. Store the nozzles and detach the whole

2
Blow air through the nozzle.
1. Detach the spring and nozzle tip as shown
at right and air blow the nozzle from the
nozzle mounting side.
2. Attach the nozzle tip and air blow the
nozzle from the nozzle mounting side.

NOTE
IIf the nozzle air path is excessively dirty, perform Step 3
and 4 below.
3
Clean the nozzle hole.
1. Pass a nozzle cleaning wire through the
nozzle hole.
2. Clean the nozzle by moving it as shown at
right.
4
Remove the nozzle cleaning wire, and
air-blow the nozzle interior with the air
blow tool as described in Step 2.
n
NOTE
When the dirt is not removed well, repeat Step 3 and 4
above.
5
Return detached nozzles to the head.
When detached nozzles from the nozzle
holder, store them to the original position and
then return to the nozzle station.

1.2.3 Cleaning the nozzle tip
A little dirt at the nozzle tip can be cleaned with the "Nozzle tip cleaning tape" that comes with the machine. If
cleaning the nozzle with an ultrasonic cleaner (option) and then cleaning with the nozzle tip cleaning tape, the
nozzle tip can be cleaned effectively.
The following describes the cleaning procedure for the spring-action nozzle tip with an ultrasonic cleaner and
the nozzle tip cleaning tape.
c
CAUTION
When cleaning the nozzle tip, use YAMAHA recommended cleaning tape (TAPE,CLEANER: KGT-M8895-00X) only.
If using other tape, the adhesive surface may adhere to the nozzle and may cause the mounting failure.
n
NOTE
See the Service Information that comes with the tape for how to use the cleaning tape.

Remove nozzles.
1. Press the emergency stop button and then
open the machine safety cover.
2. Remove nozzles from the head.
When the nozzle station is equipped.
2. Store the nozzles and detach the whole
nozzle holder.
3. Open the nozzle station shutter and detach
nozzles.
2
Clean the slide section.
If dust is in the slide section, remove it with an
air blow tool (option), etc.
3
Clean nozzles with an ultrasonic
cleaner.
1. Put nozzles into a container (such as beaker)
in an ultrasonic cleaner.
2. Pour IPA in a container until nozzles are
dipped.
3. Pour water in an ultrasonic cleaner.
4. Clean nozzles with an ultrasonic cleaner for
about 10 minutes.
c
CAUTION
DO NOT pour ethanol directly into the ultrasonic cleaner. It
must be poured in a beaker or similar container.
n
NOTE
When cleaning a nozzle with an O-ring such as
Type 8110R or Type 8011H nozzle using an
ultrasonic cleaner, remove an O-ring and clean a
nozzle itself only.

Blow nozzles.
1. Take nozzles out from an ultrasonic cleaner.
2. Blow entire nozzle to remove IPA. Intensively
blow the slide section and the air path.
