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.
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.
53304-L6-00
5
Remove excess oil remaining in the
nozzle.
Using an air blow tool, blow air for about 5
seconds from the nozzle tip, and for about 5
seconds from the nozzle attachment 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.

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 agai.
7
Reinstall the nozzle.
After checking one more time no oil
remaining in the nozzle, return the nozzle to
the head.
n
NOTE
If removed nozzles from the nozzle station, return them
to the nozzle storage positions.

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.

1.1.2 Checking the nozzle leaf springs
If nozzle leaf springs cannot hold a nozzle securely, this adversely affects pickup, recognition and mounting
operations. Periodically check the leaf springs for nozzle holding status.
n
Nozzle leaf spring inspection points
Check the following points by removing the nozzle and reattaching it to the nozzle holder.
• The nozzle leaf spring has enough gripping force.
• There is no gap between the leaf springs and the nozzle.
• The nozzle leaf spring is not deformed.
• The nozzle detaching/attaching part of the leaf spring is not worn out.
• Mounting screw should be tightened.
Checking the leaf spring condition
Screw should
be tightened.
Leaf spring should not be
warped or deformed.
There should be
no gap.
Leaf spring should
not be frayed.

NOTE
IIf any problem is found during the check work shown above, replace the leaf springs referring to chapter 4, "2.
Replacing nozzle leaf springs".
As a rule, be sure to replace a pair of parts even when only the leaf spring on one side deteriorates.
n
NOTE
Return the nozzles to the head where the nozzles were removed.
If removed nozzles from the nozzle station, return them to the nozzle storage positions.

Periodic maintenance items
1.1.3 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 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.

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.

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.
