Operating Instructions
1. Breaking a Chain
To remove an old chain or shorten a new one, use the chain breaking function:
- Identify the link to be broken. It is often recommended to grind down the head of the pin on the link you intend to break to reduce stress on the tool's breaking pin.
- Position the chain within the tool's "Break" section, ensuring the breaking pin is aligned directly with the chain pin you wish to push out.
- Slowly turn the tool's handle clockwise to advance the breaking pin, pushing the chain pin out of the link. Apply steady pressure.
- Once the pin is pushed through, the chain link will separate.

2. Pressing a Chain Link
To press the side plate onto a new master link:
- Place the master link pins through the chain ends and position the outer side plate.
- Align the tool in the "Press" position, ensuring the press plate is correctly seated against the outer side plate of the master link.
- Slowly turn the tool's handle to press the side plate onto the master link pins until it is flush and securely seated. Do not over-press.
3. Riveting a Master Link
To flare the pins of a rivet-style master link:
- After pressing the side plate, position the tool in the "Rivet" setting with the rivet flare die.
- Align the rivet flare die over one of the master link pins.
- Slowly turn the tool's handle to flare the pin. Repeat for the other pin. The flared diameter should be approximately 0.200-0.217 inches (5.1-5.5 mm) for 520/525/530 chains. Consult your chain manufacturer's specifications for exact measurements.
- Inspect the flared pins to ensure they are securely fastened and properly mushroomed.
Maintenance
- After each use, clean the tool thoroughly to remove any chain grease or debris.
- Lightly lubricate the threaded rod and moving parts with a general-purpose lubricant to ensure smooth operation and prevent corrosion.
- Store the tool in its original carrying case in a dry environment to protect it from damage and rust.
- Inspect the breaking pin and rivet flare die for wear or damage. Replace if necessary to maintain optimal performance and prevent damage to the chain.
