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.

1. Cleaning the intake filter

Remove the intake filter (Refer to Fig. 1.) every 50
hours or once a week and clean the inside of the
intake filter and the filter element with compressed air.
(Fig. 7)
Use a phillips screwdriver to disassemble intake filter
models EC6B, EC6C and EC12.  Use an allen wrench to
disassemble model EC16.
