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.

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.

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.

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.

Detach the ﬁlter cup.
