How to use the manual decoiler for roll forming machine . It is easy but few clients can not use it very well

For manual decoiler for the roll forming machine
One of my clients asked me one question. He said that when the machine is forming with the panel. the panel is not forming straightly. He asked me whether it was the problem of the manual decoiler. I wondered that i told him that send me the video of the decoiler working. And we have 13 hours difference. So he will do it when it is his working time. I am confused that so i checked the the video what he sent me, I found that he putted the wood under the support. And the height of the support is not the same. I told him to check today.
Let the decoiler keep level. It is real easy thing. Few friends can do it better. Do you know why?
