4. Setup and Preparation
Before using the Cablematic CST 500, ensure the tool is correctly configured for your specific cable type and desired strip length.
- Inspect Blades: Verify that the coring and stripping blades are clean, sharp, and free from damage. Replace blades if necessary (refer to Maintenance section).
- Cable Compatibility: Confirm that the CST 500 is the correct tool for your 500 Kcmil cable.
- Adjust Strip Length (if applicable): The tool supports strip lengths from 0.5" to 2" (12.7 to 50.8 mm). Adjust the stop mechanism if your model allows for variable strip lengths, using the provided hex keys.
- Manual or Drill Operation: Decide whether to use the tool manually with the T-handle or with a 3/8" drill for powered operation. Ensure the drill adapter is securely attached if using a drill.
5. Operation Instructions
Follow these steps for effective coring and stripping of 500 Kcmil cables:
- Prepare Cable End: Ensure the cable end is cut cleanly and squarely. Remove any burrs or irregularities.
- Insert Cable: Carefully insert the cable end into the tool until it reaches the internal stop. Ensure the cable is centered within the tool's opening.
- Engage Blades: Apply firm, steady pressure to the tool, pushing it onto the cable. The blades will begin to cut the sheath and core the dielectric.
- Rotate Tool:
- Manual Operation: Rotate the T-handle clockwise around the cable. Continue rotating and applying forward pressure until the stripping and coring process is complete.
- Drill Operation: Attach a 3/8" drill to the adapter. With the drill set to a low speed, activate the drill and apply steady forward pressure, rotating the tool around the cable until the process is complete.
- Remove Tool: Once the cut is complete, carefully remove the tool from the cable. The stripped sheath and cored dielectric material should be cleanly separated.
- Inspect Cable: Examine the prepared cable end to ensure a clean strip and core, free from nicks or damage to the conductor.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Cablematic CST 500 tool.
- Cleaning: After each use, clean the tool to remove any cable debris, insulation, or dielectric material. Use a soft brush or cloth. Avoid harsh chemicals that may damage the tool's finish.
- Blade Inspection: Periodically inspect the coring and stripping blades for sharpness and damage. Dull or damaged blades can lead to poor cable preparation and potential injury.
- Blade Replacement: If blades become dull or damaged, they should be replaced. Refer to the manufacturer's instructions for specific blade replacement procedures for your model. Use only genuine Cablematic replacement blades.
- Lubrication: Apply a light coat of machine oil to moving parts and blades occasionally to prevent rust and ensure smooth operation.
- Storage: Store the tool in its original packaging or a protective case in a dry environment to prevent corrosion and damage.
7. Troubleshooting
This section addresses common issues you might encounter with the Cablematic CST 500 tool.
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven strip or core | Dull or damaged blades; cable not inserted squarely; insufficient or uneven pressure/rotation. | Inspect and replace blades if necessary. Ensure cable is inserted straight and centered. Apply consistent pressure and rotation. |
| Tool jams or is difficult to rotate | Debris buildup; dull blades; incorrect cable size; excessive force. | Clean the tool thoroughly. Replace dull blades. Verify cable size compatibility. Reduce force and ensure smooth rotation. |
| Cable conductor damaged | Incorrect blade depth setting (if adjustable); worn blades; improper tool alignment. | Ensure blades are correctly set for the cable. Replace worn blades. Verify cable is centered and tool is aligned. |
| Tool feels loose or wobbly | Loose fasteners; worn internal components. | Check and tighten all visible screws/fasteners. If issue persists, contact Cablematic support. |
