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:

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.
c
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.
n
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
1
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.
2
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.
