OVERLOAD

 

  PROTECTOR

 

 

6. Caution in Use: 

6.1  Please check before use if wire connection is correct & air-piping connection is correct   

& hydraulic oil in tank is enough & kind of hydraulic oil is suitable. 

6.2  When press is normally operated, air supply should not be turned off absolutely. 

6.3  Check the oil tank regularly to see if there still has enough hydraulic oil. If lower than 

mid

 

position of the oil level gauge, please add oil immediately. 

6.4  The hydraulic oil should be changed every year.   

7. Method of Air Drain: (

when you use overload protector at first time or re-supply oil)

 

7.1  At air drain bolt: 

7.1.1  Adjust air regulator to 2 ~ 3 kgf/cm

2

7.1.2  Turn the air drain bolt anti-clockwise around 1/4 ~ 1/2 circle, then pump starts 

  working. 

7.1.3  Wait for around 20 seconds in order to exhaust air completely. 

7.1.4  Turn the air drain bolt clockwise to fasten it, and then pump stops working 

(hydraulic pressure is raising). 

7.1.5  If the pump still working. It means the air didn

t exhaust completely, please   

repeat step 7.1.2 ~ 7.1.4. till air is exhausted completely.   

7.1.6  Adjust air regulator to required pressure.

 

 

                                                                                                                   

 

 

 

                                                                                                                                                                                                   
 
 

7.2 At connector between high-pressure hose and cylinder of the slide: 

7.2.1  Adjust air regulator to 2 ~ 3 kgf/cm

2

7.2.2  Loosen the connector of high-pressure hose from slide, then pump starts working. 

7.2.3  Check the oil is which flowed out of high-pressure hose, till the oil didn

t bubbles 

completely, then fasten the connector. 

7.2.4  After fasten the connector of high-pressure hose, pump stops working (hydraulic 

  pressure is raising). 

7.2.5  Adjust air regulator to required pressure.
