Remember, don't try to cut steel or ACSR with these pliers as it can damage them. For maintenance, after each use, wipe the pliers clean with a dry cloth. You can also apply a light coat of oil to the moving parts to keep them working smoothly. This will help ensure that your pliers last a long time, thanks to the lifetime guarantee on quality and reliability.
