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.

Required tools
• Neutral detergent
• Air blow tool (option)
• Cleaning rag
• Replacement air filter (KHW-M8501-10X ELEMENT)
• Replacement mist filter (KHW-M8501-20X MANTLE)

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.
Turn the filter cup in the allow direction
shown in the figure with pressing the button
on the filter cup, then pull it out downward.

any moisture with clean cloth or paper.

Reattach the filter cup.
1. Adjust the button on the cup to the
position where the filter has been
removed. Push the cup upward.
