Using the Jet 708118 Universal Mobile Base is a breeze. First, adjust the width and length of the base according to the size of your JET tool. You don't need any tools for this adjustment thanks to the spring - pin snap mechanism. Once it's set, simply place your tool on the base. To move your tool, just push or pull it; the two fixed and two swivel casters will make the movement easy. When it comes to maintenance, regularly check the casters for any signs of wear or damage. If they get dirty, clean them with a mild soap and water. Also, make sure the spring - pin snap is working properly. Avoid overloading the base; it's designed to hold tools up to 600 lbs. If you're not using the base for a long time, store it in a dry place to prevent rusting.
