Using this Park Tool ratchet handle is easy. First, select the right 3/8' drive socket or bit for your job. Then, use the quick - release button to attach it to the handle. You can switch the direction of the ratchet easily depending on whether you need to tighten or loosen something. When you're done, just press the button again to remove the socket. For maintenance, keep it clean. Wipe it down after use to prevent dirt buildup. Store it in a dry place to avoid rusting. Don't use it with sockets or bits that are too big or don't fit properly, as this could damage the handle.
