3.5 Daily Operation of Air Compressor
① Connect the power.
② Check the POWER light and LCD, and verify that:
‑the POWER light is ON, and the monitor display has
appeared.
③ Check the oil level gauge, and verify that:
‑ the oil stays around the upper or lower red lines of the oil
level gauge.
④ Close the petcock and water relief valve.
⑤ Open the cooling water valve.
① Open the discharge stop valve.
② Press the START button.
‑ The compressor switches to full load operation within 15
seconds for the Fixed speed type and within 10 seconds for
the V type.
③ Check the LCD monitor, and verify that:
- the oil pressure is 12 psi (0.08 MPa) or more.
④ Check the LCD for a gradual rise of the discharge air
pressure, and verify that:
‑ the maximum discharge air pressure is less than the rated
pressure.
● When using the air compressor, do not raise the discharge pressure excessively. Operating the air
compressor over the rated pressure can result in main motor overload, shutdown of the airend and/or
damage of parts.
● If the air relief valve has blown or a protective device has shutdown the air compressor, investigate
the cause of and take corrective action. If there are any questions or comments in taking these
actions, contact the local HITACHI distributor/master dealer or representative office.

3.5.1 Preparing the air compressor
3.5.2 Starting the air compressor
Verify that the oil stays between the upper and lower red
lines of the oil level gauge while air compressor is
running. Since the oil comes back to the oil case after the
air compressor stops, the oil level during air compressor
running is lower than during air compressor stopping.
