Using these snap ring pliers is a breeze. First, open the pliers by squeezing the handles. Then, place the tips of the pliers on the snap ring. To install a snap ring, position it where it needs to go and use the pliers to expand it into place. For removal, use the pliers to compress the snap ring and pull it out. When using, make sure your hands are dry to keep a good grip. Also, don't apply excessive force as it might damage the pliers or the snap ring. To maintain these pliers, clean them after each use with a dry cloth. You can also apply a little bit of oil to the moving parts to keep them working smoothly. Store them in a dry place to prevent rusting.
