A:
Put the roll on the core so that when you pull the tape out the sticky side is facing down. Pull the tape out and thread it between the metal tape guide and the roller. Pull it up to the cutting edge and cut off the excess tape. You may then adjust the tension of the tape dispenser by turning the grey knob with the screw in the center of the core. Turn clockwise to tighten and counter clockwise to loosen the tension. Too much tension will make it harder to pull and roll out. Not enough tension will make it roll to fast and sloppy. I hope this helps.
