Air tank - Drain water

There are 2 places for draining water in the air tank:
drain valve on the top of air tank, and drain handle

3. Loosen the drain handle on the bottom of drain
separator. Check that water in the drain separator
is discharged from the drain pipe.
4. Close the drain handle after draining water firmly.

Air tank air pressure - Check

Check the air pressure gauge to see if the air pressure
in the air tank conforms to the standard.
1. Open the air pressure gauge valve.
2. Check air pressure in the air tank with air pressure
gauge.
Specified value: 2.94 MPa {30 kgf/cm
3. Close the air pressure gauge valve.

Air cleaner - Check
