Periodic maintenance items

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.

53323-L1-00

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.

53324-L1-00

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.

NOTE

A thin coat of oil is enough to lubricate the slide section.

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.

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.

Periodic maintenance items

Lubricate the bevel gear and shaft.

Using the lubrication syringe for nozzle

padding part and turbine oil (VG32), apply

one drop of oil at the inner side of bevel

gear and shaft respectively, and then

spread it with your finger.

53326-L1-10

53327-L1-10

CAUTION

Do not lubricate the bevel gear section, as foreign

matter may get caught in the gear.

Reassemble the FNC nozzle

assembly.

Use the Phillips screwdriver to reassemble

the nozzles onto the nozzle block.

CAUTION

Attach the nozzle where it was removed.

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.

CAUTION

If the nozzle assembly and SHAFT_1 combination is incorrect, the nozzles may operate erroneously or vacuum leaks

may occur during component pickup.

2.2.3 Cleaning the FNC locate pin

Inside the spline shaft of each FNC head, a locate 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 locate pin,

component pickup or mount errors tend to occur. Although depending on the operation time, we recommend

cleaning the locate pin at the time when you take apart and clean the FNC nozzle assembly.

Clean the FNC locate pin parts.

Wipe the dirt on the FNC locate pin and

spring with a cleaning cloth moistened with

alcohol.

53329-L1-10

Clean the FNC locate pin insertion

hole.

1. Blow air into the air path of the FNC

locate pin insertion section of the spline

shaft with the air blow tool (option).

2. Wipe inside the FNC locate pin insertion

section thoroughly with a spiral-tip cotton

swab moistened with alcohol.

3. After cleaning, check it is completely

clean.

53330-L1-00

NOTE

Wipe and clean to the end of the FNC locate pin

insertion section.

NOTE

Use spiral-tip cotton swabs (thickness: 4mm or less) that

are commercially available.

Lubricate the FNC locate pin.

Using the lubrication syringe for nozzle

padding part and turbine oil (VG32), apply

one to two drops of oil on the FNC locate

pin, and then spread them with your finger.

Reinstall the FNC locate pin and

spring.
