1.2 Nozzle cleaning
The following describes how to clean and lubricate the Type 30X Group nozzles. Also, clean and lubricate the
Type31X Group nozzles in the same manner.
1.2.1 Cleaning and lubricating the nozzle buffing area
e
1
Remove the nozzle from the head.
1. Press the emergency stop button and then open the machine safety cover.
2. Remove nozzles from the head. If the machine is equipped with the nozzle station, press the [Nozzle
Stn Shutter] button to open the nozzle station shutter and remove nozzles.
2
Clean the slide section.
Apply IPA (isoprophyl alcohol) or 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 sufficient air to remove IPA or
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 buffing action (spring
action).
Push the nozzle tip several times to repeat
the buffing action and spread turbine oil.
Use a lint-free cleaning cloth to wipe away
excess oil from around the nozzle.
53302-L4-20
5
Remove excess oil remaining in the
nozzle.
Air blow with the aIr blow tool for
approximately 5 seconds from the nozzle tip
side, and approximately 5 seconds from the
nozzle mounting side. 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 was removed.
Blow air through the nozzle again while
placing commercially-available oil blotting
paper over the opposite end of the nozzle,
and check for residual oil in the nozzle.
53303-L4-10
n
NOTE
Performing step 5 is usually sufficient to remove oil
remaining in the nozzle. However, if oil still remains then
blow air through the nozzle once again.
7
Return the nozzle to its original
position.
After verifying again that the nozzle is free of
oil, return the nozzle back to the head.
n
NOTE
When the nozzle is removed from the nozzle station,
return it back to the original stored position.

Step 6
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.

1.2.2 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 of 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.

1
Remove nozzles.
1. Press the emergency stop button and
then open the machine safety cover.
2. Remove nozzles from the head. If the
machine is equipped with the nozzle
station, press the [Nozzle Stn Shutter]
button to open the nozzle station shutter
and remove nozzles.
2
Clean the slide section.
If dust is found 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.
53361-L4-00
n
NOTE
When cleaning a nozzle with an O-ring such as Type
304A or Type 307A nozzle using an ultrasonic cleaner,
remove an O-ring and clean a nozzle itself only.
4
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.

Clean the nozzle tip.
Push the nozzle tip vertically against the
adhesive surface of the nozzle tip cleaning
tape several times to remove dirt.

CAUTION
If turning or tilting a nozzle while pushing it against the
tape, the adhesive surface may stick to the nozzle.
6
Lubricate the slide section.
See"1.2.1 Cleaning and lubricating the
nozzle buffing area" in this chapter to
lubricate the nozzle buffing area.
7
Return nozzles to the head.
Return the removed nozzles to the head.

NOTE
If removed nozzles from the nozzle station, return them
to the nozzle storage positions.
