5. Setup
Follow these steps to prepare your hydraulic puncher for operation:
Image: Visual guide for the initial setup steps of the hydraulic puncher.
- Prepare the Workpiece: Select a metal plate within the specified thickness and material limits. For the desired punching location, pre-drill a pilot hole: Φ11.5mm for the small shaft or Φ20.5mm for the large shaft.
- Insert the Shaft: Turn the appropriate shaft (large or small, depending on the die size) and insert it into the punch head.
- Attach Dies: Attach the lower die first, then the upper die, ensuring they are securely in place.
6. Operating Instructions
Once the puncher is set up, follow these steps for safe and effective punching:
- Apply Pressure: Rotate the oil return knob clockwise until it is fully tightened. This builds hydraulic pressure.
- Punch the Hole: Grip the movable handle and pump it to activate the hydraulic mechanism, punching the hole through the metal plate.
- Release Pressure and Remove Waste: After punching, remove the cut waste material. Then, rotate the oil return knob counter-clockwise to release the hydraulic pressure. The operation is now complete.
Important Operating Precaution:
To prevent the shaft from bending, always ensure the punch head is placed flat on the ground or a stable surface, and apply even force to the die, shaft, and metal plate during the punching process.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your hydraulic puncher.
- Cleaning: After each use, clean the puncher and dies to remove any metal shavings or debris.
- Lubrication: The dies are pre-oiled at the factory to prevent rust. This is not an oil leak. Periodically apply a thin layer of rust-preventative oil to the dies and other metal components to ensure smooth operation and prevent corrosion.
- Shaft Inspection: The shaft is a consumable item. Regularly inspect it for signs of wear or bending. If the shaft is bent or damaged, it should be replaced. Spare shafts can be purchased separately (ASIN: B0BR4W5T16).
- Storage: Store the hydraulic puncher and its accessories in the provided iron case in a dry, secure environment.

8. Troubleshooting
If you encounter issues with your Bonvoisin Hydraulic Puncher, refer to the following common problems and solutions:
- Problem: Shaft Bending
Solution: Ensure even force is applied during operation and that the punch head is placed flat on the workpiece. Do not exceed the specified material thickness limits. The shaft is a consumable part and may need replacement if bent or damaged. (Refer to ASIN B0BR4W5T16 for spare shafts). - Problem: Hydraulic Pump Not Operating or Loss of Pressure
Solution: Ensure the oil return knob is fully tightened clockwise before starting operation. If the issue persists, it might be due to an internal ball valve being stuck. With the oil return knob tightened, try gently tapping the bottom part of the pump (where the hydraulic cylinder connects to the hose) on a hard surface a few times. This can help dislodge the internal ball valve and restore pump function. - Problem: Oil on Dies or Tool Surface
Solution: The oil observed on the dies or tool surface is factory-applied rust-preventative oil and is not an oil leak. This is normal and helps protect the components during storage and transport. - Problem: Damaged Storage Case
Note: The SYK-15 is packed in a heavy iron case. Due to the product's weight (over 10kg), the case surface may incur minor scratches or dents during transportation. This is generally cosmetic and does not affect the tool's functionality.
