Using this multi - purpose bench vise is easy. First, find a stable surface and use the four mounting points to secure the vise. To hold a material, adjust the 360 - degree rotating head to the desired angle. You can use the 30 - degree indexing increments for quick and accurate setup. For round objects, use the V - jaw to hold them vertically. When working with pipes, the replaceable pipe jaws are very handy. Remember, this product has a Prop 65 warning about cancer and reproductive harm, so take necessary precautions. To keep your vise in good condition, regularly clean the jaws and the rotating parts. If the jaws get worn out, you can replace them easily. The large built - in anvil can be used for forming and shaping materials, but avoid using excessive force that could damage it. Also, keep the vise dry to prevent rusting on the cast iron and ductile iron parts.
