Using this bench vise is easy. First, secure it firmly to your workbench using the double lockdowns on the 120° swivel base. You can then rotate the vise to the angle you need for your task. Place your workpiece between the 6 - inch jaws and use the handle to tighten the grip. The grooved steel jaw inserts will help keep the workpiece in place. When using the anvil work surface, make sure to use proper tools for the job. Remember, this product has a Prop 65 warning about cancer and reproductive harm, so take necessary precautions. For maintenance, regularly clean the vise to remove debris and rust. Lubricate the moving parts to keep them working smoothly. Keep it in a dry place when not in use to prevent corrosion.
