I've done it both ways, and pulling on the nut side while pulling the wrench towards you will almost always result in the axle shifting and the belt running out of alignment. I now use a small ratchet strap on the right non drive side to pull the axle forward to keep the adjusters seated, the belt tension keeps the left drive side adjusters seated, and tighten the nut pushing up on the torque wrench. What a pain in the rear!
