Using the Rothenberger Press Sling SV42/SV54 is straightforward. First, make sure your press machine has an axial thrust of 32 - 34 kN as this press sling is designed for such machines. Place the fitting you want to press in the right position between the press jaws. Then operate the press machine to start the pressing process. When using, avoid over - pressing or applying excessive force that may damage the jaws. For maintenance, keep the press sling clean after each use. Wipe off any dirt or debris. Also, regularly check for signs of wear, especially on the areas with DURA LAZR TEC treatment. If you notice any significant wear or damage, it's best to replace the parts to ensure continued safe and effective use.
