e
Check that the oil was removed.
If needed, 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.

Lubricate the bevel gear, shaft and
nozzle sliding section.
Use the lubrication syringe (KV8-M8870-00X)
and turbine oil (VG32) to lubricate at the
following locations.
1. Apply one drop of oil at each of the
bevel gear inner sides and shaft, and
then spread it with your finger.
2. On spring-action nozzles, apply a small
amount of oil at the sliding section and
jog it back and forth several times by
pushing the nozzle tip. Remove the
excess oil and then blow with air.

CAUTION
Do not lubricate the bevel gear section, as foreign
matter may get caught in the gear.
t
Check the nozzle spring-action.
If the spring-action is still poor even after
cleaning, replace the nozzle with a new
one.

Checking for residual oil
Oil blotting paper
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.

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 Reassembling the FNC nozzle assembly.
1
Reassemble the FNC nozzle
assembly.
1. Open the [Unit]-[Head] tab screen and
press the [Head] button to lower the
head to which you are reassembling the
FNC assembly.
2. Rotate the R-axis belt so that the spline
shaft is positioned where the FNC nozzle
assembly can be easily reassembled,
and then set so that the inscribed mark
in the middle of the index holder faces
the front.
3. Hold the FNC nozzle assembly with the
cutout facing towards the front and Type
202F nozzle pointing downwards, and
insert it into the FNC head until the FNC
lock pin inside the index holder is slightly
raised.

2
Insert the bevel gear and shaft.
While slightly pressing the FNC nozzle
assembly up, insert the bevel gear and shaft
into the center hole of the FNC nozzle
assembly from the front, and align the mark
on the bevel gear with the mark on the
index holder.
53319-F8-00
c
CAUTION
Reassemble the nozzle assembly, bevel gear and shaft
in their original combination for each FNC head, without
mixing them with parts for other heads. If this
combination is changed, the bevel gear may not rotate
smoothly or the pickup vacuum level may degrade.
