Using this service jack is easy. First, make sure the area where you'll use it is flat and stable. Position the jack under the part of the vehicle you need to lift. Slowly turn the jack's handle to raise the load. Don't exceed the 2000 lbs capacity. When lowering, turn the handle in the opposite direction carefully. As for maintenance, keep it clean and check for any signs of wear or damage regularly. If you notice any issues, don't use it until it's fixed.
