Please find the list of potential problems below and follow the steps to remediate the issue. If you encounter a problem not listed below or the issue persists after following the steps as outlined, please do not hesitate to contact us.

 

I. Head Will Not Close

1. Ensure that the air supply is on and check the air regulator (part 13AR1) to see if the air gauge reads 100 PSI (~ 7 kgf/cm^2). Do not allow the air pressure to exceed 100 PSI. Check for loose connections and replace any air tubes that may be punctured. If any air tubes are punctured, the noise caused by leaking air will be apparent and easy to locate.

 

2. Locate the pair of control relays (part 12CR1) within the timer control panel (part12TCP1). You will need to open the timer control panel by removing the screw in the front. Monitor the lights on the control relays. They should light up as each red (close) button is pressed.

 

a. If the light on one of the control relays is not lit, check the button sensor (part 12BS1) located under the red (close) button. Replace the button sensor if it is no longer function properly. If the button sensor is working properly, then the unlit control relay may require replacement.

 

3. Locate the small solenoid valve (parts 13SVS1) towards the bottom left side of the press. Remove the right air tube of the small solenoid valve. The air tube should be connecting the small solenoid valve to the closing cylinder (part 12CCS251). Allow air to flow through to the solenoid valve by pushing the two red (close) buttons. There should be a strong blast of air coming from the solenoid valve.

 

a. If air is not coming from the solenoid valve there may be a clog in the air regulator (part 13AR1), solenoid valve (parts 13SVS1) or air tubes connecting these parts. Check to see if air can flow freely through these parts. If a certain part is not emitting air, remove all attached air tubes and clean any residue that may be preventing air flow.

 

4. Locate the limit switch (part 13LS1) next to the pressing cylinder (part 13PCL61) towards the back of the press. Ensure that the handle of the limit switch is not depressed when the head is in its open position. If the limit switch is depressed, readjust its position so that the handle of the limit switch is only slightly touching the pressing cylinder when the head is in its open position.

 

5. If the problem persists, please contact us directly for more details.

 

II. Head Will Not Close Completely

1. If the machine head is unable to close at all, please refer to the previous section for guidance.

 

2. Ensure that the air supply is on and check the air regulator (part 13AR1) to see if the air gauge reads 100 PSI (~ 7 kgf/cm^2). Do not allow the air pressure to exceed 100 PSI. Locate the pressure regulator (part 13PR1) behind the front panel of the press. Ensure that the pressure set to approximately 60 PSI (~ 4 kgf/cm^2).

 

3. The press head may be unbalanced where one end of the head may be lower than the other. To rebalance the press head, find the two hex socket screws located in between the head springs. The head springs can be found on top of the press head, two on either side of the arm, used to hold the press head and arm together. Tighten the hex socket screws until the press head separates from the pressing arm by approximately ½". This will enable the press head to rebalance once the head is in the closed position. Loosen the hex socket screws if necessary.

 

Please note that the following step is considered a significant adjustment and may cause damage to the press if the modifications are not done properly.

 

4. Locate the buffer rod (part 11BR1) towards the back of the press. The buffer rod connects the handle of the shock absorber (part 13SA851) to the bottom of the pressing arm (part 11PA1). Carefully detach the buffer rod and the bearings from shock absorber and pressing arm. Loosen the bearings at the top and bottom part of the buffer rod so that the entire rod is longer compared to its original length. Do not allow the bearings to sit on the outer threads of the rod as the bearings may detach from the rod during operation. Place the buffer rod back to its original position - it should be in between the shock absorber and pressing arm.

 

III. Head Closes Too Slowly

1. Ensure that the air supply is on and check the air regulator (part 13AR1) to see if the air gauge reads 100 PSI (~ 7 kgf/cm^2). Do not allow the air pressure to exceed 100 PSI. Locate the pressure regulator (part 13PR1) behind the front panel of the press. Ensure that the pressure set to approximately 60 PSI (~ 4 kgf/cm^2).

 

2. Check for loose connections and replace any air tubes that may be punctured. If any air tubes are punctured, the noise caused by leaking air will be apparent and easy to locate.

 

3. Air flow may be restricted to the pressing cylinder. Locate the small solenoid valve (parts 13SVS1) towards the bottom left side of the press. Remove the right air tube of the small solenoid valve. The air tube should be connecting the small solenoid valve to the closing cylinder (part 12CCS251). Allow air to flow through to the solenoid valve by pushing the two red (close) buttons. There should be a strong blast of air coming from the solenoid valve.a. If air is not coming from the solenoid valve or air flow is weak there may be a clog in the air regulator (part 13AR1), solenoid valve (parts 13SVS1) or air tubes connecting these parts. Check to see if air can flow freely through these parts. If a certain part is not emitting air, remove all attached air tubes and clean any residue that may be preventing air flow.

IV. Head Closes Too Quickly or Slams when Closing

1. Ensure that the shock absorber has adequate levels of oil. To refill the oil, loosen the pipe plug located on top (center) of the shock absorber (part 13SA851). Do not unscrew the two slot screws located on either side of the pipe plug as it will cause the shock absorber to leak oil. Be sure to use SAE No. 10 (non-detergent) oil and fill the shock absorber to approximately 80% full.

 

2. The current setting on the shock absorber may be too weak to control the press head when closing. To strengthen, turn the right nut of the shock absorber clockwise until the desired setting.

 

3. The air pressure may be too high. Lower the pressure by adjusting the pressure regulator (part 13PR1) found behind the front panel of the press.

 

4. If the problem persists, please contact us directly for more details.

 

V. Head Closes But Does Not Press

1. Air pressure to the press may be too low. Locate the pressure regulator (part 13PR1) behind the front panel of the press. Ensure that the pressure set to approximately 60 PSI (~ 4 kgf/cm^2).

 

2. Locate the limit switch (part 13LS1) next to the pressing cylinder (part 13PCL61) towards the back of the press. Ensure that when the press is in the closed position the limit switch is activated. The handle of the limit switch should be depressed allowing the pressing cylinder to function. If the limit switch is not depressed, adjust the limit switch by manually widening the gap between the handle and the base of the switch. If the limit switch continues to not activate, you may need to adjust the positioning of the limit switch so that it is closer to the wider part of the pressing cylinder.

 

3. Find the medium solenoid valve (part 13SVM1) located to the right of the small solenoid valve (part 13SVM1) near the bottom of the press. Remove the upper right air tube of the medium solenoid valve. This air tube connects the medium solenoid valve to the quick exhaust valve (part 13QEV1). Allow air to flow through to the solenoid valve by pushing the two red (close) buttons. There should be a strong blast of air coming from the solenoid valve. If there is no air or air flow is weak, the medium solenoid valve requires replacement.

 

4. Locate the quick exhaust valve (part 13QEV1) in front of the pressing cylinder (part 13PCL61). Remove the air tube and detach the quick exhaust valve from the pressing cylinder. Detach the air muffler (part 13AM1) from the quick exhaust valve. Open up the quick exhaust valve by unscrewing the four screws on top of the valve. Check to see if the plastic-like material within the quick exhaust valve is punctured or cracked. If so, the quick exhaust valve requires replacement. Attach and return the quick exhaust valve, air muffler and air tube to their original positions.

VI. Head Will Not Open

1. Remove the air tubes connecting the solenoid valves (parts 13SVM1 and 13SVM1) to the closing cylinder (part 12CCS251) and pressing cylinder (part 13PCL61). If the head opens after the air tubes are removed from the cylinders, there is a defect in the pressure regulator (part 13PR1) or solenoid valves. Locate the defective part by removing the air tubes to each part one at a time.

 

2. The timer relay (part 12TR1) within the timer control panel (part 12TCP1) may be defective. For more details, please contact us directly.

 

VII. Head Will Not Open Completely

1. The current setting on the shock absorber (part 13SA851) may be too tight. To loosen, turn the right nut of the shock absorber counterclockwise until the head able to open completely. Do not loosen the right nut too much as it will cause the head to slam.

 

2. Remove the air tubes connecting the solenoid valves (parts 13SVM1 and 13SVM1) to the closing cylinder (part 12CCS251) and pressing cylinder (part 13PCL61). Manually push the press head upward to see if the head is able to move. Attached the air tubes back to the solenoid valve/cylinders.

 

3. Locate the black circular bumper in between the pressing arm and directly behind the stainless steel table. There should not be a gap between the bumper and the back of the stainless steel table. If there is a gap, there may be a defect in the closing or pressing cylinders. From the back of the press, observe the length of rod remaining on the closing cylinder - there should be at most 2.5" remaining on the rod. Any length longer than 2.5" indicates that the closing cylinder may be clogged from within. Similarly, there should be at most 1.5" remaining on the rod for the pressing cylinder. Any length longer than 1.5" indicates that the pressing cylinder may be clogged from within. Please contact us directly for more details on how to fix this issue.

 

Please note that the following step is considered a significant adjustment and may cause damage to the press if the modifications are not done properly.

 

4. Locate the buffer rod (part 11BR1) towards the back of the press. The buffer rod connects the handle of the shock absorber (part 13SA851) to the bottom of the pressing arm (part 11PA1). Carefully detach the buffer rod and the bearings from shock absorber and pressing arm. Tighten the bearings at the top and bottom part of the buffer rod so that the entire rod is shorter compared to its original length. Place the buffer rod back to its original position - it should be in between the shock absorber and pressing arm.

 

VIII. Head Opens Too Slowly

1. The current setting on the shock absorber (part 13SA851) may be too tight. To loosen, turn the left nut of the shock absorber counterclockwise until the desired setting. Do not loosen the left nut too much as it will cause the head to slam.

 

2. The quick exhaust valve (part 13QEV1) located in front of the pressing cylinder (part 13PCL61) may be clogged. Remove the air tube and detach the quick exhaust valve from the pressing cylinder. Detach the air muffler (part 13AM1) from the quick exhaust valve. Open up the quick exhaust valve by unscrewing the four screws on top of the valve. Clean the inside and return the quick exhaust valve, air muffler and air tube to their original positions. If the problem persists, the quick exhaust valve may need replacement.

 

3. Locate the main springs (part 12MS1) on the pressing machine. The current configuration of the main spring may be too loose. To tighten, locate the spring adjusting screw on the end of the main spring and adjust the spring until it is adequately tight. Apply the same adjustment to both springs.

 

4. If the problem persists, please contact us directly for more details.

 

IX. Head Slams When Opening or Head Opens Too Quickly

1. Ensure that the shock absorber has adequate levels of oil. To refill the oil, loosen the pipe plug located on top (center) of the shock absorber (part 13SA851). Do not unscrew the two slot screws located on either side of the pipe plug as it will cause the shock absorber to leak oil. Be sure to use SAE No. 10 (non-detergent) oil and fill the shock absorber to approximately 80% full.

 

2. The current setting on the shock absorber may be too weak to control the press head when opening. To strengthen, turn the left nut of the shock absorber clockwise until the desired setting.

 

3. The press head may not be opening up completely. For more details refer to instructions listed in section VII above.

 

4. If the problem persists, please contact us directly for more details.

 

X. Head Is Applying Too Much Pressure

1. Locate the pressure regulator (part 13PR1) behind the front panel of the press. Decrease the air pressure by adjusting the pressure regulator until the desired amount of pressure.

 

2. You may want to simultaneously decrease the pressure to the press as noted in step 1 and strengthen the shock absorber by turning the right nut of the shock absorber clockwise until the desired setting. Both adjustments will significantly lower the pressure applied by the head.

 

3. If the problem persists, please contact us directly for more details.

 

XI. Steam is Leaking from the Head Steam Valve

Ensure that the handle of the head steam valve is on the same level as the top of the valve. Detach the head steam valve (part 11HSV1) from the press and disassemble the head steam valve. There are two possible causes for the leaking steam - either the spring or the disk holder within the head steam valve is worn and requires replacement. To determine if the disk holder is worn, check to see if the inner part of the disk holder (white circular piece) is uneven or irregular. Replace the worn piece, reassemble the head steam valve and return the valve to its original position.

 

XII. Steam Is Leaking from the Buck

The disk holder within the buck valve may be worn. Turn off all steam to the press and drain all steam/water by turning on the ball valve located on the left side of the press. Be sure all steam is removed from the press before adjusting the buck valve as it will cause injuries. Locate the buck valve (part 12BV1) behind the buck cover. Detach the buck valve from the press, disassemble the buck valve, and find disk holder. Check to see if the inner part of the disk holder (white circular piece) is uneven or irregular. If so, the disk holder requires replacement.
