• Read all instructions for each procedure before beginning. Improper use of the tool can
cause breakage.

• Make sure the tool is clean and apply grease to all threads before assembling and using. This will
help the tool operate more smoothly and allow you to feel tension when using the tool.

• When breaking drive chains larger than #520, it is recommended to grind off the rivet heads
first, if possible. This will significantly reduce the load on the tool and help prevent premature wear

or damage to the breaking tip.

• All tightening procedures are to be performed by hand only, using a 14mm wrench. Do not use
extensions or power tools of any kind or the tool may be damaged.

Use only the correct breaking tip for your application, or you will damage the tip.

Included in this kit: 3.8mm Breaking Tip for drive chains #428 - #630.

Assemble the tool as shown in Image B and the diagram below for breaking chains. Thread the alignment bolt
into the body. Insert the breaking tip 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1-Place the tool over the chain as shown in Image B. The breaking tip must be withdrawn at least 2mm into
the alignment bolt to clear the end of the chain pin. Do not withdraw the breaking tip 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 breaking
tip, so do not attempt to break the chain with the alignment bolt retracted or you will damage the breaking tip.

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 breaking tip should
push smoothly into the chain link. IMPORTANT: If the chain pin doesn’t start to break free, or you don’t feel
the breaking tip going into the chain link smoothly, back out the alignment bolt just enough to check that the
breaking tip is correctly lined up with the chain pin. Once the breaking tip 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.
