Using this WILTON Mechanics Pro Vise is a breeze. First, mount it securely on a stable surface using the four mounting points. Then, you can use the 360° swivel base to position the vise at the angle you need. To hold your workpiece, open the jaws by turning the spindle. The needle roller thrust bearing makes it easy to apply and release a strong clamping force. You can use the large anvil work surface for striking tasks. When it comes to maintenance, keep the enclosed spindle clean and lubricated to ensure smooth operation. The precision - machined slide bar should be checked regularly for any signs of wear. As the vise has a Prop 65 warning, be aware of the potential cancer and reproductive harm. Always follow the safety instructions in the manual.
