- Load Fasteners: Place the eyelet or snap fastener components into their respective holders on the die set. Ensure they are correctly oriented.
- Position Material: Carefully position your material (fabric, paper, leather, etc.) over the lower die, aligning it where the fastener is to be applied.
- Activate Press: Depending on the model, activate the press using the foot pedal or a designated button on the control panel. The machine will automatically apply the fastener.
- Inspect: After each application, inspect the fastener to ensure it is securely and correctly set. Adjust settings as needed for optimal results.
- Power Off: When finished, turn off the main power switch and unplug the machine from the power outlet.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your machine:
- Cleaning: Regularly clean the machine, especially the die area, to remove dust, material scraps, and fastener residue. Use a soft, dry cloth. For stubborn residue, a slightly damp cloth can be used, ensuring the machine is unplugged and completely dry before next use.
- Lubrication: Periodically apply a small amount of machine oil to moving parts as indicated in the machine's specific lubrication points (if any are visible or specified). Avoid over-lubrication.
- Die Inspection: Inspect die sets for wear or damage. Worn dies can lead to inconsistent results and should be replaced.
- Storage: When not in use, store the machine in a clean, dry environment, protected from dust and extreme temperatures.
