Of course it would have to a lot of tension if you are not level and are required to jack it up more than an inch or two. Any of the instructions clearly state to ensure you are level. I had to lift my mine up a little too but because I was on level ground, there was not enough tension to cause any harm to myself or property.
I can kill this topic here. Please ensure you are on level ground prior to performing the CHF. If you need to jack one of them up more than an inch or two, it is likely you are not on very level ground and I would recommend you re-level and try it again. Best of luck to all.
