Let me add one more thing. I had never used a chain like this and never used a tool like this either. This tool didn't have instructions, so I had to figure it out. Now this will be the third time, and I think I got it. believe me ...I usually buy an extra link with a new chain.. if you want I can scan the directions that came with the RK tool...may help. Let me know and I will scan them tomorrow at work and post them up.
