Symptom:
The chain is skipping or running roughly.
Resolution:
If caused by stiff links in the chain, you should clean and lubricate the chain.
If the chain continues to skip, the machine should not be rowed, and you should contact Concept2 immediately. We recommend purchasing and installing the chain axle sprocket kit, which has part number PN1915.
To assist you with the installation process, you can watch a video tutorial here.
