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.

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.

q
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.
53306-F9-00
w
Remove excess oil remaining in the
nozzle.
Using an air blow gun, 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.
e
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 12 is usually sufficient to remove oil
remaining in the nozzle. However, if oil still remains then
blow air through the nozzle once again.

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.

Lubricate the bevel gear and shaft.
Using the lubrication syringe (KV8-M8870-
00X) and turbine oil (VG32), apply one drop
of oil at each of the bevel gear inner sides
and shaft, and then spread it with your
finger.

c
CAUTION
Do not lubricate the bevel gear section, as foreign
matter may get caught in the gear.
t
Reassemble the FNC nozzle
assembly.
Use the Phillips screwdriver to reassemble
the nozzles onto the nozzle block.
c
CAUTION
The screwdriver bit size may slightly differ between
manufacturers. Use the screwdriver that matches the
recessed pattern on the screw head.
Take care not to lose the small spring inserted in the
spring-action nozzle.

Precautions when replacing the bevel gear shaft (SHAFT_1)
Caution is required when replacing only the bevel gear shaft (SHAFT_1) during maintenance since a nozzle assembly and
SHAFT_1 must be used in the correct combination. There are 3 grades each of nozzle assemblies and SHAFT_1 depending
on the hole inner diameter and shaft outer diameter. They are identified by marks ( , , etc.) as shown below. Always
use the correct combination of a nozzle assembly and SHAFT_1 which have the same mark.
c
CAUTION
If the nozzle assembly and SHAFT_1 combination is incorrect, the nozzles may operate erroneously or vacuum leaks
may occur during component pickup.

1.2.3 Cleaning the FNC lock pin
Inside the spline shaft of each YG100RA FNC head, a lock pin (or locate pin) is used to lock the rotation of the
FNC nozzle assembly when the selected nozzle points downwards. If dust or grime adheres to this lock pin,
component pickup or mount errors tend to occur. Although depending on the operation time, we recommend
cleaning the lock pin at the time when you take apart and clean the FNC nozzle assembly.
1
Clean the FNC lock pin parts.
Wipe the FNC lock pin and spring with a
lint-free cleaning cloth moistened with
alcohol.
53377-F9-00
2
Clean the FNC lock pin insertion
hole.
1. Blow air into the air path of the FNC lock
pin insertion section of the spline shaft.
2. Wipe inside the FNC lock pin insertion
section thoroughly with a lint-free cotton
swab moistened with alcohol.
53379-F9-00
Reference
Use spiral-tip cotton swabs (thickness: 4mm or less) that
are commercially available.
3
Lubricate the FNC lock pin.
Using the lubrication syringe (KV8-M8870-
00X) and turbine oil (VG32), apply one or
two drops of oil to the FNC lock pin and then
spread it with your finger.
4
Reinstall the FNC lock pin and
spring.
