Warning:
DO NOT USE POWER TOOLS at any time to tighten or loosen any part of this tool.
Every procedure performed with this tool should only be done by hand using the supplied slide lever or a 14mm wrench. Do not use a wrench extension or breaker bar. Doing so may damage the tool.
Be sure the tool is clean before each use. Tool threads should be lubricated to ensure smooth operation and to allow tactile feel for any binding or excessive tension while in use.

Improper use or installation may result in damage to the chain and/or total chain failurecausing damage to the vehicle and/or severe injury or death.
It is recommended that only qualified motorcycle service technicians attempt any chain modification.

Proper selection of the correct breaker pin is critical. Please refer to the list below for the correct breaker pin size.
2.2mm breaker pin for use with cam chains
2.9mm breaker pin for use with 420 size chains
3.8mm breaker pin for use with 428, 520, 525, 530(50), 532 and 630 size chains

When breaking a chain size 520, or larger it is recommended-but not necessary-to grind off the rivet head of the chain roller pin. Doing so can minimize stress on the tool and may help reduce the chance of damaging the breaker pin.
Assemble the tool as shown in Image A
1. Thread the alignment bolt into the tool body.
2. Choose the correct breaker pin for the chain that it is being used on.
3. Slide the spring up the shaft of the correct breaker pin.
4. If you are breaking a cam chain you must thread the upper pin guide on to the alignment bolt and insert the bottom pin guide into the tool body hole as shown in Image B.Use of the 2.2mm breaker pin without the guides will damage or destroy the breaker pin. NOTE:Be sure to cover the cam chain tunnel with a clean ragor towel to prevent parts from dropping in.
5. Insert the breaker pin and spring into the alignment bolt.

Warning:
6. Thread the push-bolt into the alignment bolt. Only thread afew turns. DO NOT tighten. The breaker pin should still be recessed in the alignment bolt at least 2mm as shown in ImageC.

5. Begin to tighten the push-bolt using the supplied slide leverora14mmwrenchtodrve out the chain rollerpin. There will be some tension on the bolt as you begin to drive out the chain roller pin.

If you feel it is taking too much effor, STOP loosen the push-bolt, then loosen the alignment bolt, and restart at step1. lf too much force is used the breaker pin may be damaged or destroyed. The effort will essen as the chain roler pin is driven out. The chain roller pin will fall out of the tool body hole when completed .
