Frequently Asked Questions

Can this tool rivet a #630 chain?

No — the jumbo tool breaks #630 chains but only rivets up to #530. For #630 riveting, use the separate Motion Pro Quad stake rivet kit (57-8142).

How do I set up the tool for breaking vs. riveting?

The tool handles both operations. Bolts to a workbench or vise for heavy use, or clamp by handle for lighter jobs. Swap components as needed for each operation.

Can I use an air wrench with this tool?

Yes — when bolted to a solid surface, you can use air or electric wrenches to drive the chain through the breaker mechanism.

Is the master link press kit included?

Yes — the press kit for side plates up to #530 comes in the box.

What steel are the screws and attachments made from?

86L20 heat-treated steel for maximum durability under heavy use.
