Oil level is higher than the upper red line before staring
and between the two red lines after starting. This is nor-
mal because some oil in the oil separator tank is pres-
sure-fed to oil cooler and oil piping to lower oil level.
Control oil level, therefore, during operation.
①Make sure that oil level is higher than the upper red
line.
②Make sure again during operation that oil level is
between the two red lines, because it lowers after
starting.
● Do not operate the machine with the pressure excess of its rated pressure. Excessive pressure gives
overload to the motor and may damage some parts or even cause SHUTDOWN of the compressor.
● Investigate the cause and take necessary measures when the Relief Valve functions or the compres-
sor stops by other safety device. Ask your dealer or your nearest Hitachi regional office if there is any
question.
● When the
SCREW stops and restarts frequently, repeats load-and-unload operation in a short peri-
od, or the ambient temperature and humidity are high, open the valve at the oil drain port to check
whether condensate has been collected in the oil separator tank. If you do not observe this instruc-
tion, the air end (rotors, bearings, etc.) and the components rust internally to cause a failure and/or
the oil deteriorates. For more information,
see p. 19.
CAUTION
For safety, the machine cannot be operated for 5 seconds
after turning the power on even if the START button is
pressed. If the START button is pressed within the period
between 5 and 15 seconds after the power-on, the
STANDBY light blinks for up to 10 seconds for prepara-
tion and then the compressor is started.
