4. About the thermal protector
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) Place the knob of the pressure switch in the “OFF”
positon and disconnect the plug from the receptacle
(Fig. 2).
(2) Check for the following possible causes fi rst: lack
of proper ventilation, or an outside-air or room
temperature that is too high.
(3) If the extension cord does not conform to the
specifi cations given on page 7 replace with an
extension cord such as that shown on page 7. If the
capacity of the power supply is insuffi cient, increase
the power supply capacity to remove the cause of a
fl ow of excessive current (over-current).
(4) Wait approximately 30 minutes.
(5) Start up. If the motor still stops during operation,
please contact the service center.
