Using these Klein D511 - 8 slip - joint pliers is easy. First, select the appropriate jaw position based on your electrical wiring task. The serrated jaws will grip the wire firmly, and you can use the shear - type cutter to make precise cuts. When using, always remember not to use them to cut steel or ACSR as it can damage the pliers. For maintenance, keep the pliers clean and dry. The nickel - chrome plating helps prevent rust, but if you notice any dirt or debris, wipe it off with a dry cloth. That's it! These pliers will serve you well for a long time if you take good care of them.
