Getting the breaker ready for use

To start using this tool, you need to start by bench-mounting it. For a successful bench-mounting, pick an appropriate workbench- it must be stable, secure, and level to adequately support the tool weight, work material, and the pressure applied to it when breaking the chain or rivet spinning.

Refer to your user manual for detailed instruction on how to bench-mount your chain breaker.The tool is intended for two main tasks namely breaking apart the chain, and reassembling the chain.

In any case, it’s important that you wear protective gear- safety goggles, leather gloves, etc.- if you mind your safety. You would also want to keep your hands off the breaker punch, spinner die, spinner sleeve, and the thrust die when operating the tool. Otherwise, you might experience severe pinch hazards in these areas.

Let’s dive into the Operational instructions…

To Break/Disassemble The Chain

  • Set your chain to the correct notch on the breaker anvil. Ensure that the rivet lines correctly lines up with the hole in the base of slot present in the anvil.
  • Place the anvil as well as the chain directly under the breaker punch.
  • Lower the lever so that it lowers the punch onto the rivet. Ensure the rivet is centered on the rivet, and the rivet is centered on the hole at the base of the anvil.
  • Pull down the lever so as to drive the rivet out of your chain.
  • If the rivet binds, recheck alignment of all the parts. Apply some penetrating oil; try to push the rivet out of the chain again.
  • When the rivet has come out successfully, remove your chain from the anvil and check to see if there are any link damages.

To Reassemble/Spin The Chain:

  • Choose between the small or large thrust dies and spinners and insert them into the thrust handle and the spinner sleeve respectively (use a matched set of dies at all times; avoid mixing sizes).
  • Apply some grease to the rivet and insert it into place- assembling the chain loosely.
  • Now drape your chain over guide wheels. This enables you to hold it into the right position for efficient spinning. You can also adjust the wheels positions using the wheel locking fasteners. Make sure the rivet is centered on dies).
  • Rotate the thrust handle in a clockwise direction until your chain rivet appears against the spinner die. Double check to ensure the rivet, chain links openings, and the dies are properly lined up.
  • Apply some oil to the dies’ faces.
  • Turn the spinner handle in a clockwise motion to start forming a rivet head. Meanwhile, turn the thrust handle slowly to ensure the rivet remains centered and to offer substantial resistance to any pressure delivered by spinner die.
  • When the rivet head has been formed, release the chain by turning the thrust and spinner handles counterclockwise.
  • Finally, check the rivet to ensure it is properly developed. Also, check the chain to ensure it moves freely and is not damaged.
