Using this agitator is easy. First, make sure your washing machine is turned off and unplugged. Then, place the agitator on the splined shaft in your washing machine. Use a bolt (not included) to secure it in the center. When using your washing machine, the agitator will help clean your clothes effectively. Remember, this agitator doesn't come with a lint filter, top cap, or insert. So, if you need those, you'll have to get them separately. For maintenance, regularly check the agitator for any signs of wear or damage. If it seems loose or makes strange noises, stop using the washing machine and check the bolt. Keep it clean by wiping it down occasionally. This way, your agitator will last a long time and keep your washing machine working well.
