Using this tool set is straightforward. For the Lineman's Pliers, grip them firmly and use the cutting edge for wires or the gripping part for holding objects. The Long Nose Pliers are great for reaching into tight spots. The Angled Head Diagonal-Cutters are perfect for cutting wires close to surfaces. When using the wire stripper, select the right size slot for the wire you're working with. For the screwdrivers, simply insert the tip into the screw head and turn. Remember to keep your hands dry and clean when using these tools. After use, wipe them down with a dry cloth to remove any dirt or debris. Store them in a dry place to prevent rusting. If you notice any damage, stop using the tool and get it repaired or replaced.
