2. Secure the machine to the base using the provided screws and hexagon wrenches.
3. The base can then be clamped or bolted to a workbench for maximum stability.

7. Operating Instructions

7.1 Preparing for Punching

1. Ensure all safety precautions are observed.
2. Connect the power cable to a suitable electrical outlet.
3. Select and install the correct punch die for your material and desired hole size.
4. Mark the punching location on your workpiece.
5. Position the workpiece under the punching head, aligning the mark with the center of the die.

7.2 Punching Procedure

1. With the workpiece correctly positioned, firmly hold the machine (or ensure it is securely mounted).
