Using your Klein J203-8 Long Nose Side-Cutters is a breeze. To cut wires, just place the wire between the cutting blades and squeeze the handles. The high - leverage design makes it easy, so you don't have to use a lot of force. When you need to grab or loop a wire, use the long nose. It's great for getting into small spaces.
As for precautions, these pliers are not insulated, so don't use them on live electrical wires. Also, keep them out of reach of children.
To maintain your pliers, after each use, wipe them down with a clean cloth. If they get dirty, you can use a mild soap and water to clean them, then dry them thoroughly. Periodically, check the hot - riveted joint for any signs of looseness. With proper care, your Klein J203-8 pliers will serve you well for a long time.
