caption: The image shows a drawing of a brick wall with a machine attached to it, which appears to be a machine used to build a brick oven. The machine is composed of several components, including a handle, a lever, and a control panel. The handle is used to adjust the temperature and pressure of the oven, while the lever is used for controlling the temperature. The control panel is located on the side of the machine, allowing the user to adjust it to their desired level of pressure.
