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.
