4. About the thermal protector
This item is not necessary if your compressor is not
equipped with the thermal protector reset switch
shown in Fig. 6.
The thermal protector operates to stop the motor
when a problem such as a motor overload, etc.,
occurs. If the motor should stop during operation,
proceed as follows.
(1) Turn the pressure switch knob to the OFF position
(Fig. 1) and disconnect the plug from the
receptacle.
(2) If the extension cord does not conform to the
specifications given on page 6, replace with an
extension cord such as that shown on page 6. If
the capacity of the power supply is insufficient,
increase the power supply capacity to remove the
cause of a flow of excessive current (over-current).
(3) Wait approximately 5 minutes, then press the
reset switch of the thermal protector (Fig. 6).
(4) Start up. If the motor still stops during operation,
please contact the service center.
