The Pro Series Adjustable Chain Breaker is a great and affordable tool.

Suitable for use on 3/32" to 1/8" chains.

*Adjustment screw must be used to secure the chain and prevent damaging the tool. Please refer to the video for help*

Please note:
To prevent damage to the driving pin and alignment guides.
Take care to ensure the chain is secured evenly in the chain breaker with the driving pin aligned with the chain pins.
The backing screw in the stock of the chain breaker should be wound against the back of the chain to support it. This will take all load through chain breaker.
Damage to these components is generally caused by miss use and won't be covered under warranty.
