5. Operating Instructions
Operating the SILCA Bravo II Professional involves a few key steps:
- Power On: Turn on the main power switch, usually located on the side or front of the machine. The halogen lamp should illuminate the work area.
- Key Clamping:
- Insert the original key into one side of the four-sided clamp. Ensure it is seated firmly and correctly aligned.
- Insert the blank key into the corresponding clamp on the other side. The automatic alignment feature will help position the blank key correctly.
- Tighten the clamps securely to prevent any movement during cutting.
- Micrometric Adjustment: Use the micrometric adjustment knob to fine-tune the cutting depth. This is crucial for achieving an accurate duplicate. Perform a test cut on a scrap key blank if possible, or make small adjustments and check the key profile.
- Cutting Process: Engage the cutting mechanism. The semi-automatic operation will guide the cutter along the profile of the original key, duplicating it onto the blank. Maintain a steady, controlled movement.
- Using the Integrated Brush: After cutting, use the integrated brush to remove any metal shavings or burrs from the newly cut key and the machine's cutting area.
- Power Off: Once cutting is complete, turn off the machine and unplug it from the power source if not in immediate use.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your SILCA Bravo II Professional:
- Cleaning: Regularly clean the machine, especially the cutting area, clamps, and integrated brush, to remove metal dust and debris. Use a soft brush or compressed air. Always disconnect power before cleaning.
- Cutter Inspection and Replacement: Periodically inspect the cutting wheel for wear or damage. A dull or chipped cutter will result in poor key duplication. Replace cutters as needed, following the manufacturer's guidelines.
- Belt Inspection: Check the drive belt for signs of wear, cracking, or looseness. A worn belt can affect motor performance. Replace if necessary.
- Lubrication: Apply a small amount of light machine oil to moving parts and slides as recommended by SILCA to ensure smooth operation. Avoid over-lubrication.
- Lamp Replacement: If the halogen lamp fails, replace it with an identical type and wattage. Ensure the machine is unplugged before replacing the lamp.
7. Troubleshooting

- Machine Does Not Start:
- Check if the power cord is securely plugged into a live outlet.
- Ensure the main power switch is in the 'ON' position.
- Verify the circuit breaker or fuse for the outlet has not tripped.
- Poor Cut Quality / Inaccurate Duplication:
- Check if the original and blank keys are securely clamped and properly aligned.
- Inspect the cutter for wear, dullness, or damage. Replace if necessary.
- Adjust the micrometric knob for precise depth setting.
- Ensure the machine is clean and free of debris that might interfere with cutting.
- Excessive Noise or Vibration:
