Using this washing machine agitator is easy. First, make sure your washing machine is turned off and unplugged. Then, remove the old agitator from the splined shaft in the center of the machine. Take your new agitator and place it on the splined shaft. Use a bolt (not included) to secure it in the center. When it comes to usage, just run your washing machine as you normally would, and the agitator will do its job of thoroughly cleaning your clothes. For maintenance, after each use, wipe down the agitator to remove any dirt or debris. Check the connection to the splined shaft regularly to ensure it's secure. Don't use harsh chemicals on the agitator as it might damage the surface. If you notice any signs of wear or damage, it's a good idea to replace the agitator promptly.
