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

replace these parts.

Inspection and maintenance

2.3 Adjusting the conveyor belt tension

The conveyor moves by belt drive to load boards ready for printing and to unload the finished boards. 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:

Items to be prepared

• Hex wrench (5mm)

Press the emergency stop button.

Loosen the tension adjusting bolt.

The tension adjusting bolt is located on the right side of the conveyor and linked to the idler on the belt

side. Loosen the bolt (but do not remove it) using hex wrenches (5mm).

Adjust the belt tension.

Slide the tension adjusting bolt towards the outer or inner side of the machine to adjust the tension.

Inspection and maintenance

2.4 Inspecting and cleaning the air/mist filters

Air/mist filters are used to prevent oil, mist and other impurities in the air compressor from penetrating into the

machine. These filters should be inspected and cleaned periodically as instructed below.

CAUTION

The air coupler should be disconnected to safely perform the work. When disconnecting it, be careful not to allow oil,

water, or impurities to splash outward. Also take care since a large air exhaust sound is produced when disconnecting

the air coupler.

Required tools

• Neutral detergent

• Air blow tool (option)

• Cleaning rag

• Replacement air filter (KG7-M8501-40X FILTER ELEMENT)

• Replacement mist filter (KV8-M8502-40X MIST FILTER ELEMENT)

CAUTION

When performing air blow, wear dust-proof goggles and mask to protect your face from blown dust, etc.

Cleaning the filter cup

Check the inside of the filer cup.

Check for oil or water deposits in the filter

cup through the window. 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.

Remove the filter cup.

While pressing the button on the side of the

filter cup, turn it clockwise, and pull the filter

cup downwards. The cup you have removed

has a double structure. The inner transparent

cup should be cleaned.

53204-N3-00

Clean the inside of the filter cup.

1. Lightly clean the filter cup with water.

2. Then, 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.

Reattach the filter cup.

1. Align the button on the side of the cup

with the attach/detach position and

push the cup upwards.

2. Turn the cup counterclockwise until you

hear a click.

NOTE

Leave the ﬁlter cup removed to clean the air ﬁlter as

explained in the next procedure.
