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
on the bottom of drain separator.
1. Open the drain valve slowly, and check that water
in the tank is drained from drain pipe.
2. After water is drained and the air is discharged in
the tank, tighten the drain valve firmly.
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.
Note: If the specification of air tank differs from the
contents of this operation manual, follow the
manufacturer's operation manual.

Air Tank Air Pressure - Check

1. Check the air pressure gauge to see if the air pres-
sure in the air tank conforms to the standard.
2. Open the air pressure gauge valve.
3. Check air pressure in the air tank with air pressure
gauge.
Specified value:
For air direct starting: 2.94 MPa {30 kgf/cm
psi]
For air motor: 0.98 MPa {10 kgf/cm
4. Close the air pressure gauge valve.
Note: If the specification of air tank differs from the
contents of this operation manual, follow the
manufacturer's operation manual.
