4. Setup
Before operating the chain tool, ensure you have selected the correct components for your task (splitting or riveting) and chain size.
- Identify Chain Size: Determine the size of the chain you are working with (e.g., 420, 520, 630). This will help you select the appropriate cutting pin.
- Select Pin: Choose one of the three cutting pins (2.2 mm, 2.9 mm, or 3.8 mm) that best fits the pin diameter of your chain. The pin should be slightly smaller than the chain pin to be pushed out.
- Assemble for Splitting:
- Insert the selected cutting pin into the main chain press tool.
- Ensure the anvil is correctly positioned to support the chain.
- Assemble for Riveting:
- For riveting, you will typically use the press plate and the riveting hammer in conjunction with the main tool. Specific riveting instructions are detailed in the Operating section.
5. Operating Instructions
5.1. Splitting a Chain
Follow these steps to safely and effectively split a chain:
- Prepare the Chain: Position the chain so that the pin you wish to remove is accessible. It is often helpful to support the chain on a sturdy surface or in a vise.
- Insert Cutting Pin: Ensure the correct cutting pin is installed in the chain press tool.
- Position the Tool: Place the chain press tool over the chain link, aligning the cutting pin directly with the center of the chain pin you intend to push out. The anvil should be positioned on the opposite side of the chain to support it.
- Apply Pressure: Slowly turn the handle of the chain press tool clockwise. This will advance the cutting pin, pushing the chain pin out of the link.
- Observe Progress: Continue turning until the chain pin is fully pushed out and the chain separates. Do not force the tool if resistance is excessive; re-check alignment.
- Remove Tool: Once the chain is split, turn the handle counter-clockwise to retract the cutting pin and remove the tool from the chain.
5.2. Riveting a Chain
To join a new chain or master link using the riveting function:
- Assemble New Link: Connect the new chain ends or master link plates, ensuring the pins are correctly inserted through the bushings.
- Prepare for Riveting: Replace the cutting pin in the chain press tool with the riveting hammer. Position the press plate on the opposite side of the chain pins to be riveted.
- Position the Tool: Place the chain press tool over the master link, aligning the riveting hammer with one of the chain pins. The press plate should be directly behind the pin head.
- Rivet the Pin: Slowly turn the handle clockwise. The riveting hammer will expand the end of the chain pin, creating a secure rivet. Apply steady, even pressure.
- Check Rivet: After riveting one pin, inspect the rivet head to ensure it is properly flared and secure. Repeat the process for the other pin(s) on the master link.
- Final Check: Once all pins are riveted, ensure the master link moves freely and is securely joined to the rest of the chain.
6. Maintenance
Proper maintenance will extend the life of your WilTec Chain Tool.
- Cleaning: After each use, wipe down the tool with a clean cloth to remove any grease, dirt, or metal shavings.
- Lubrication: Periodically apply a light coat of machine oil to the screw threads and moving parts of the chain press tool to ensure smooth operation and prevent rust.
- Inspection: Regularly check all components, especially the cutting pins and riveting hammer, for wear, bending, or damage. Replace any worn or damaged parts immediately.
- Storage: Always store the tool and its components in the provided plastic case in a dry, clean environment to protect it from moisture and physical damage.
7. Troubleshooting
If you encounter issues while using the chain tool, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chain pin not moving or excessive force required. | Incorrect pin alignment, wrong cutting pin size, or rusted/stuck chain pin. | Re-align the tool carefully. Ensure the cutting pin is slightly smaller than the chain pin. Apply penetrating oil to the chain pin if it's rusted. Do not force the tool. |
| Cutting pin bends or breaks. | Misalignment, excessive force, or incorrect pin size for the chain. | Ensure precise alignment. Use steady, controlled pressure. Verify the cutting pin size is appropriate for the chain. Replace damaged pins. |
| Rivet not forming correctly. | Improper alignment of riveting hammer, insufficient pressure, or incorrect press plate positioning. | Ensure the riveting hammer is centered on the pin. Apply firm, even pressure. Verify the press plate supports the chain correctly. |
| Tool feels stiff or difficult to operate. | Lack of lubrication, dirt/debris in threads. | Clean the tool thoroughly and apply a light machine oil to the screw threads and moving parts. |
