Step 4:
Electric:
Step 5:
Check conditions of punches ( tools) and tools holder.

Step 6:
Encoder;
Different machineries will have different encoders, but the purpose (keep a balance on the length of the stroke in both sides) is the same.
The best way to check if the encoder is working properly is to bend similar piece of materials in both ends of the machine at the same time and compare the angle bended.
Prepare the above test and if you find a discrepancy between the angles
In the samples bended, adjust the encoder bar until you get the same angle of bending in both side of the machine.
Refer to the manual of the machine to proceed, because different brands will have different encoder and different way to adjust them.
Step 7:
Back gauge
Verify that back gauge in good conditions.
Set up the press brake to a fixed distance, 100mm or closet , and check if the distance from the centre of the die is as was prefixed.
Step 8:
