Using your Jet 453308 JHJ-8 Hydraulic Bottle Jack is easy. First, place the jack on a flat and stable surface. You can use it in upright, horizontal, or angled positions depending on your task. Connect the pump handle to start the operation. For lifting or other tasks, slowly pump the handle until you reach the desired height. When you're done, release the pressure valve to lower the jack. Always make sure the load is within the 8-ton capacity. Keep the jack away from extreme heat or cold. Regularly check the hydraulic fluid level and the chrome-plated piston and ram for any signs of wear. If there are any leaks or damage, stop using the jack immediately and have it checked by a professional.
