Using the WILTON Mechanics Pro Vise is easy. First, find a stable surface and use the 4 mounting points to secure the vise firmly. Then, rotate the 360° swivel base to the position you need for your work. Place your workpiece between the jaws and use the spindle to close the jaws and hold the piece tightly. When you're done, simply reverse the spindle to release the clamping force. For maintenance, regularly check the enclosed spindle to make sure it's clean and well - lubricated. Keep the vise in a dry place to prevent rust. Avoid using excessive force on the anvil work surface to prevent damage. Remember, this product may cause cancer and reproductive harm, so take necessary safety precautions when using it.
