Using these locking pliers is easy. First, open the pliers by squeezing the handles. Then place the jaws around the object you want to grip and adjust the screw to tighten the grip. When using, make sure the object is firmly held to avoid slippage. Don't use them to grip objects that are too hard or sharp, as this may damage the jaws. After each use, clean the pliers with a dry cloth to remove dirt and debris. Store them in a dry place to prevent rusting. Regularly check the screw and pivot points for smooth operation. If they seem stiff, you can apply a little lubricant.
