I'd be very worried about doing any kind of jerking motions like that. Could break chain (where are the ends going to pop to?). Could take 3ph up past its stops. Use common sense. Do gentle motions. They can be forceful but gentle. Don't do jerky stuff like taking a running start with a chain or rope or even the FEL. You're not a kid any more tearing stuff apart. This is expensive stuff you're dealing with. Some of that stuff, like breaking chains or falling limbs can kill you.
