BREAKING CHAINS
Assemble the tool as shown in Image B and the diagram below for breaking chains. Thread the alignment bolt into the
body. Insert the extractor pin into the spring and drop them into the alignment bolt with the spring under the tip head.
Thread the push bolt into the alignment bolt above the tip.
Image B shows a drive chain in place.
1. Place the tool over the chain as shown in Image B. The extractor pin must be withdrawn at least 2mm into the
alignment bolt to clear the end of the chain pin. Do not withdraw the extractor pin too far into the alignment bolt or it can
get hung up inside the alignment bolt. One end of the chain pin will be held in position by the end of the alignment bolt,
while the other end is held in position by the hole of the tool body.
2. Tighten the alignment bolt securely against the side plate of the chain, but do not over-tighten or the alignment bolt
and tip could drift out of position. The alignment bolt is for aligning and supporting the extractor pin, so do not attempt to
break the chain with the alignment bolt retracted or you will damage the extractor pin.
3. Read this step all the way through before beginning. Tighten the push bolt by hand only with a Philips
screwdriver or a 14mm wrench until the chain pin is pushed completely out and through the hole in the tool body. You
will feel some initial tension as the chain pin begins to shear, but afterwards the extractor pin should push smoothly into
the chain link. IMPORTANT: If the chain pin doesn’t start to break free, or you don’t feel the extractor pin going into the
chain link smoothly, back out the alignment bolt just enough to check that the extractor pin is correctly lined up with the
chain pin. Once the Extractor pin and chain pin are aligned properly, tighten the alignment bolt back down and start over
at the beginning of this step. Do not apply excessive force or use air tools or you may damage the tool.
