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. (The filter closer to
the air coupler is the air filter and the other one is the mist filter.)

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.
Reference
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
Disconnect the air hose from the
air coupler.
c
CAUTION
When disconnecting the air hose, be careful not to
allow oil, water or impurities to splash outwards.
3
Remove the filter cup.
While pressing the button on the side of the
filter cup, turn it clockwise, and pull the filter
cup downwards.

any moisture with clean cloth or paper.
