5.5 Base section
5.5.1 Replacing the air and mist filter element and cleaning the cup
An air filter and an oil mist filter are installed in YRM20 to prevent oil, water, and impurities in the air
compressor from entering the machine.
This section describes the procedure for inspecting and cleaning these filters and also for replacing the filter
media (filter elements). Detach the air coupler from the air supply fitting to ensure worker safety.
1
Detach the air coupler of air supply.
1. Rotate the "Air supply/exhaust" switch to
left (EXH) to shut down the air supply.
2. Detach the air coupler from the air supply
fitting.
c
CAUTION
When disconnecting the air coupler from the air supply
fitting, be aware that a loud air exhaust sound occurs.
Also be aware of oil, water, and impurities that may spray
out.
2
Check the inside of the filer cup visually
for oil or water deposits in the filter
cup.
If the window is dirty, follow the procedure of
Step 3 to Step 6 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.

Oil mist filter:
Push down the cup's button, and turn the cup
45-degree counterclockwise. Then pull
downward to detach it.
