- To assist you in lifting the bar on the paper trimmer, please move the blade carriage to the center of the bar. Take hold of the bar on either side of the blade carriage (do not use the blade carriage for lifting.) Put your fingers from each hand on the bar and place your thumbs on the trimmer surface. Now lift up on the bar with your fingers and use your thumbs as braces on the trimmer surface. This gets easier with each use.
