Combination pliers maintenance and care
To ensure your tools lasts as long as possible, you should look after them and store them safely.
Only use individual pliers within their specifications. For instance, you shouldn't try to use light pliers with heavy materials. Pliers shouldn't be used to cut any hardened wires unless they're specifically designed for that purpose. You shouldn't use anything to extend the handles of pliers, or hit then with a hammer - use larger pliers instead.
Don't use pliers as a hammer: most pliers are not strong enough for this. Avoid using pliers around excessive heat, as high temperatures can change the properties of metals. Never use pliers near live electrical wires unless they have VDE insulated handles.
Cleaning and storage
Keep pliers clean and dry them before storing, as steel exposed to moisture will rust. Occasionally oil the pivot point; this should keep the movement smooth and help to prevent rust. Store pliers where they won't be damaged - for instance, in a drawer or toolbox.
