Mount the adhesive screws according to the instructions on the package and allow the glue to dry (see instructions).
One steel ruler for the paper feed is placed approx. 2 cm under the roll holder. The other steel ruler serves as a tear-off rail and is mounted approx. 50-60 cm below the first rail. To mount the roll holder, the threaded rod must be detached, and the paper roll removed. Apply the angles and reinsert the roll. Pull the paper through both rails. Attach a felt-tip pen to a string on the side of the roll holder.
Finally, screw the small cap nuts onto the adhesive screws.
