Key Features:
- Nominal Output: 490kN (50tf) for powerful crimping.
- Separable Head Design: Enhances flexibility and ease of use in confined spaces.
- Wide Application Range: Suitable for copper wires from 8mm² to 1000mm² with hexagonal crimping.
- Durable Construction: Built for long-lasting performance in demanding industrial environments.
Setup
- Unpacking: Carefully remove the tool from its packaging and inspect for any shipping damage.
- Hydraulic Pump Connection: Connect the hydraulic hose from a compatible hydraulic pump (not included) to the tool's hydraulic inlet. Ensure connections are secure and free of leaks.
- Die Installation: Select the appropriate crimping dies for the wire size and connector type. Insert the dies into the crimping head, ensuring they are correctly seated and aligned.
- System Check: Before first use, cycle the tool a few times without a workpiece to ensure smooth operation and proper hydraulic fluid flow.
Operating Instructions
- Prepare Workpiece: Strip the wire insulation to the appropriate length for the connector.
- Position Connector: Insert the wire into the T-type connector.
- Place in Dies: Carefully place the connector and wire into the crimping dies, ensuring proper alignment.
- Initiate Crimping: Activate the hydraulic pump to begin the crimping cycle. The dies will close, applying pressure to the connector.
- Complete Crimping: Continue applying pressure until the crimping cycle is complete (the dies fully close or the pressure relief valve activates on the pump).
- Release Pressure: Release the pressure from the hydraulic pump to retract the dies.
- Remove Workpiece: Carefully remove the crimped connector from the tool.
- Inspect Crimp: Visually inspect the crimp for proper formation and security.
Maintenance
- Cleaning: After each use, clean the tool, especially the crimping dies, to remove any debris or residue.
- Lubrication: Periodically lubricate moving parts and pivot points with a suitable hydraulic tool lubricant.
- Hydraulic Fluid: Regularly check the hydraulic fluid level in your pump and replenish as needed. Use only recommended hydraulic fluid.
- Die Inspection: Inspect crimping dies for wear, cracks, or damage. Replace worn or damaged dies immediately to ensure proper crimps.
- Storage: Store the tool in a clean, dry environment. Apply a light coat of oil to exposed metal surfaces to prevent corrosion if storing for extended periods.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Incomplete crimp | Insufficient hydraulic pressure; incorrect die size; worn dies; improper workpiece placement. | Check hydraulic pump pressure; verify die size; replace worn dies; ensure correct workpiece positioning. |
| Dies do not retract | Hydraulic pressure not fully released; obstruction in dies. | Ensure pump relief valve is open; check for debris in dies. |
| Oil leakage | Loose connections; damaged seals. | Tighten all hydraulic connections; contact qualified service personnel for seal replacement. |
For issues not listed here, or if solutions do not resolve the problem, please contact Izumi Seiko customer support or a qualified service technician.
