The Dahle 448 Premium Rotary Trimmer with a 51.2-inch cut length is a top - notch tool for precise trimming of thicker paper and materials. It comes with a self - sharpening blade that cuts in both directions, ensuring long - lasting sharpness. The dual - cylinder aluminum guide bar offers great strength when dealing with thick items. An automatic clamp securely holds your work, preventing any shifting. Engineered in Germany, it guarantees high precision and accuracy. It also includes a space - saving steel stand with a paper catch for the perfect cutting height. And for safety, the ground steel blade is encased in a protective housing.

Using the Dahle 448 Premium Rotary Trimmer is easy. First, place your material on the trimming surface and use the automatic clamp to hold it firmly in place. Then, use the self - sharpening blade to cut in either direction. The dual - cylinder aluminum guide bar will help you make straight and accurate cuts. When using, make sure your hands are away from the blade area. Also, keep the area around the trimmer clean to avoid any debris affecting the cutting. For maintenance, regularly check the blade's sharpness. If it starts to cut less smoothly, the self - sharpening feature will help restore its edge. Clean the guide bar and the stand occasionally to keep them in good condition. The steel stand can be adjusted to the optimal cutting height, so make sure it's set correctly for your comfort and precision.
