Using your WILTON Mechanics Pro Vise is a breeze. First, find a stable workbench and use the four mounting points to secure the vise firmly. You can rotate the 360° swivel base to get the best working angle for your project. When you need to hold an object, open the jaws by turning the spindle. The precision slide bar ensures the front jaw moves smoothly and stays stable. Once the object is in place, use the needle roller thrust bearing to easily apply a strong clamping force. As for maintenance, regularly check the enclosed spindle. Wipe off any dirt and add lubricant as needed to keep it running smoothly. The large anvil work surface can handle a lot of hammering, but try to avoid overly hard blows that could damage it. Also, be aware that this product has a Prop 65 warning about cancer and reproductive harm, so take appropriate safety measures when using it.
