2.2.4 Parts recommended for periodic replacement

For parts listed in the table below, it may be predicted that the service life of the part is expired or the part

deteriorates even though no trouble is found through the visual check during the periodic inspection.

To maintain the performance of the machine at its optimal operating level, it is recommended to periodically

replace these parts.

Periodic replacement parts

Part No. Part name Q'ty Location used Replacement interval

KHT-M3674-02X

TUBE 25

ø25-suction hose connected from

the left side of the cleaner unit to

the rear of the machine.

Replace periodically every

time the total production

quantity reaches 3 million

boards.

KHU-M3756-01X PUMP 1 Solvent pump

Replace every time the

number of suction unit

operation cycles reaches

1,440 thousand cycles.

Check the operation records

on the [Unit log]-[Cleaner] tab

screen.

KHW-M8582-40X VALVE 1 EA valve

Replace every time the

operation count reaches 20

millions.

CAUTION

The part Nos. given in this manual are the original part Nos. which were assigned to the parts when this manual was

issued. Because these part Nos. may be changed without prior notice, be sure to verify the latest part Nos. before

ordering parts.

Inspection and maintenance

2.3 Adjusting the conveyor belt tension

The boards are moved by conbeyor belt drive. If the conveyor belts are too loose, they may slip on the pulleys

causing unstable board transfer. If the belts are too tight, they may break or wear excessively. The tension of

each belt on the fixed and movable rails should be adjusted evenly. If necessary, adjust the tension as follows:

2.3.1 Board carry-in and carry-out conveyors

Required tools

• Hex wrench (3mm)

• Phillips screwdriver

Change the conveyor width to a

convenient width for maintenance

work.

1. Press the [Width] button to display the

"Conveyor Width" dialog.

2. In the "Target Width" box, enter a width

large enough for maintenance work

(about 200mm) and press [OK].

The conveyor is changed to the width

that was just entered.
