Periodic maintenance items

5.4.2 Cleaning the air and mist filters and cups

An air filter and an oil mist filter are installed at the air supply fitting of the machine to prevent oil, water, and

impurities in the air compressor from entering the machine. This section describes the procedure for inspecting

and cleaning these filters and also for replacing the filter media (filter elements).

Detach the air coupler from the

machine.

To ensure worker safety, detach the air

coupler from the air supply fitting on the

machine.

CAUTION

When disconnecting the air coupler from the air supply

ﬁtting, be aware that a loud air exhaust sound occurs.

Also be aware of oil, water, and impurities that may

spray out.

Check the inside of the filer cup.

Visually check for oil or water deposits in the

filter cup. If the window is dirty, follow the

steps below to clean the filter cup.

TIP

The drain cock at the bottom of the ﬁlter cup is an

auto-drain type. It automatically drains the oil or water

when deposited in the cup. We recommend

connecting a hose to this drain cock.

Detach the filter cup.

While pressing the cup's button, turn the cup

to the left and then pull downward to

detach it. The detached cup has a double

construction. Only the transparent inner cup

requires cleaning.

Clean the inside of the filter cup.

1. Lightly clean the filter cup with water.

2. Pour water-diluted neutral detergent into

the filter cup and clean the inside while

shaking it.

3. Air blow the filter cup and wipe away

any moisture with clean cloth or paper.

53388-N9-00

Check the filter media status.

Rotate the media to detach it, and check it

for soiling and clogging. If soiled, replace it

with a new media indicated in the

Consumable Parts List.

Attach the media and cup.

Attach the media and cup by reversing the

removal procedure given above.

Reconnect the air coupler to the air

coupler.

After connecting the air coupler, check that

no air is leaking.

6. 2-year maintenance

This section describes 2-year maintenance items.

6.1 RS head

6.1.1 Clean/lubricate scissors gear

This section describes cleaning and lubricating the rotating axis (N-axis) in the rotary unit and the gears in the

rotating axis (R-axis) of each head all housed in the RS head

Prepare for work.

1. Remove all items sensitive to magnetic fields such as wristwatches and magnetic ID cards.

2. Press the emergency stop button and then open the machine safety cover.

3. Use the CLAMP ON/OFF switch to lower the feeder exchange carriage and detach it.

4. Move the head unit to a convenient position for maintenance work.

Clean the scissors gear.

While turning the scissors gear (R-axis), wipe

away the dirt and grime from the gears (2

scissors gears and the gear in front of them)

with a lint-free cloth.

Apply grease.

1. Apply the specified grease (LG2) by

hand or with a lint-free cloth to the

scissors gears of the N-axis and R-axis.

2. Turn the R-axis gear manually so that the

grease spreads into the entire gear.

Wipe off excess grease.

Wipe off excess grease with a lint-free cloth.

6.1.2 Cleaning

lubricating upper part of the nozzle shafts

The procedure for cleaning and lubricating the upper part of RS head nozzle shafts is described below. The

dedicated oil (KMB-M3855-00X) is required to lubricate the upper part of nozzle shafts.

Prepare for work.

1. Remove all items sensitive to magnetic fields such as wristwatches and magnetic ID cards.

2. (With nozzle station) Store all nozzles to nozzle station.

3. Press the emergency stop button and then open the machine safety cover.

4. Use the CLAMP ON/OFF switch to lower the feeder exchange carriage and detach it.

5. Move the head unit to a position where easy to perform the task.

NOTE

If the machine is not equipped with nozzle station, see "How to lower RS head/nozzle shafts" to lower Z-axis manually

before detaching nozzles.

Clean the upper part of the shaft.

1. Use your finger to press down the nozzle

shaft spring of the head to be cleaned.

2. Wipe away dirt or grime from the upper

part of the nozzle shaft using a cotton

swab.

53393-N9-00

Apply grease.

Using a cotton swab dampened with the

specified oil (oil for upper part of shaft),

apply a thin uniform coat in approximately

a 10 mm range on the upper part of the

shaft.

NOTE

If the spring of the head to be lubricated is in a position

where difﬁcult to lower, then turn the rotary unit by

referring to "How to lower RS head/nozzle shafts"

described earlier. The rotary unit can also be turned by

turning the R-axis gear by hand.

Clean and lubricate the other shafts

in the same way.

Clean and lubricate the other shafts using

the procedure in Steps 2 and 3.
