Using your Jet 453313K hydraulic bottle jack is easy. First, place the jack on a flat and stable surface, like the heavy - duty welded base is designed for. Make sure it's positioned correctly according to your lifting task, whether it's upright, horizontal, or at an angle. Then, use the included pump handle to start the lifting process. When using, always stay within the 12.5 - ton load capacity to ensure safety. Avoid overloading the jack as it can cause damage to the internal components. After each use, clean the jack with a dry cloth to remove any dirt or debris. Check the chrome - plated piston and ram regularly for signs of corrosion or wear. Store the jack in a dry place, especially if you're in an area with extreme climates. If you notice any leaks or unusual noises during operation, stop using the jack immediately and have it inspected by a professional.
