4. PROTECTIVE DEVICE
If internal heat builds up during operation due to
clogging of the airflow orifice, if the machine is
used in a highly heated environment or if an ab-
normality occurs inside the machine, the thermal
protector for preventing burnout may be activat-
ed to stop the motor operation. The buzzer will
sound in this case. In such a case:
1. (Fig.G,K) Turn the power switch off and
disconnect the power plug from the out-
let.
•
For buzzer sounding patterns, see
page 16.
2. (Fig.C,L) Connect the power plug to the
outlet and turn the power switch on to
resume the operation.
•
If the motor has sufficiently cooled down,
the resumed operation may active the pro-
tective device soon after. In other cases,
the operation may not resumed when you
turned the power switch on. In such a
case, wait for about 30 minutes for the mo-
tor to cool down before restarting the ma-
chine.
3. If the protective device was activated
when there were no apparent problems
existing in the operating environment,
stop using the compressor and send it to
your dealer or authorized service facility
for checkups or repairs.
5. ABNORMALITIES DURING
OPERATION
•
If you detect any abnormalities, do not op-
erate the compressor.
If you encounter any of the following abnormal
phenomena, turn off the power switch immedi-
ately, disconnect the power plug from the outlet
and send the machine to your dealer or author-
ized service facility for checkups or repairs.
1. The following problems may occur even
when there are no problems with the
power supply or wiring: (See "PROTEC-
TIVE DEVICE" on page 15.)
•
Turning on the power switch does not start
up the machine.
•
Motor vibration is generated
2. Abnormal sounds are generated during
operation. (See "AUTOMATIC ADJUST-
MENT OF OPERATING POWER" (IN-
VERTER CONTROL) on page 17.)
3. The safety valve instead of the pressure
sensor is activated, allowing the com-
pressed air to blow out.
4. Air leakage happens.
5. Pressure does not increase. (See
page 17)
6. An electrical shock-like pain is felt when
touched the metal part.
7. Other abnormalities than the above that
is recognized during operation.
