Important tips: 1: The pipe you are cutting needs to be anchored somehow or it will be significantly harder to get the needed twisting motion with the wrench. 2: Oil the chain! I used air tool oil and it worked great. 3: Once you have the wrench around the pipe, do a light squeeze for at least 1/4 turn, 1/2 turn would be better but in tight spaces a 1/4 will work. Then squeeze the handles REALLY hard and you will feel the blades sink into the small groove. Hold as tight as you can and twist 1/4 to 1/2 inch turns back and forth. Don't let your grip loosen. It took me about 7 minutes to do this pipe in the pictures, so it does take a little work to get it done, but nothing labor intensive. Overall I am very happy with this tool, did the job in a tight space no problem.
