Operation Method

1. Turn on the power, turn on the operating switch on the control console, start the oil pump button, and hear the oil pump rotating and making a sound.

2. Adjust the bending stroke. When the bending stroke goes from top to bottom, there must be a gap to avoid causing certain wear and tear on the machine. Therefore, it is necessary to set the bending stroke for manual or electric micro-adjustment.

3. Select the bend notch. Generally speaking, the thickness of the selected board is about 8 times the width of the notch. For example, if the board is 5cm, the notch needs to be about 40cm.

4. Adjust the bending stopper. The stopper behind the bending machine also requires certain manual or electric fine-tuning.

5. Depress the foot pedal switch to bend the aluminum bar. The foot pedal switch of the bending machine can be released and depressed at any time. Release it to stop working, and depress it to continue bending. ,

6. When the bending machine stops working, turn off the operating switch on the operating table, turn off the power, and clean the bending machine workbench to make its surface clean and tidy.

7. Pay attention to maintaining the bending machine at any time to increase the service life of the equipment.
