Using your Jet JHJ - 60 hydraulic bottle jack is a breeze. First, make sure the surface where you place the jack is flat and stable. You can operate it in upright, horizontal, or angled positions depending on your needs. To lift, simply use the included pump handle to start the pumping action. When you're done, slowly release the pressure to lower the load safely. As for maintenance, keep the jack clean and dry. Check the chrome - plated piston and ram regularly for any signs of corrosion. Since it can handle extreme climates, it's suitable for various environments, but still, avoid leaving it in very wet or dirty conditions for long periods. Also, ensure the hydraulic system is protected by the internal by - pass mechanism. And remember, this jack meets ANSI/ASME B30.1 and PALD - 1 standards, so use it with confidence.
