Using the Klein D248 - 8 diagonal cutting pliers is straightforward. Simply place the non - ferrous wire or soft metal between the jaws and squeeze the handles. The high - leverage design will make the cutting process easier. When working, keep in mind that these pliers are not insulated, so don't use them on live electrical wires. For maintenance, after each use, wipe the pliers with a dry cloth to remove any debris. You can also apply a light coat of oil to the cutting edges and the joint to prevent rusting. Store them in a dry place to keep them in good condition.
