Cocking the PIAT generally was a 2-man op. One guy stood the Projector on its butt and the other guy jumped on the cocking-arm.
One guy can do it. Both feet on the butt, two hands on the pistol grip (fingers locked like you're helping buddy over a fence) then a great big bear hug lifting up and a giving a twist CCW to lock it. Doing it on the ground in a prone position could get a little testy.
