HOW TO USE This Stirling engine model？

This Stirling engine model adopts double-cylinder double-piston rocker arm linkage structure, with a small generator and LED lamp beads, and is equipped with a voltage digital display meter. The overall design is very cool and eye-catching.

Usages: Put the Stirling engine model on a horizontal table, inject butane gas fuel into the gas tank, ignite and preheat for 30 seconds, then turn the flywheel by hand to help start.

Educational Toys: LED lamp beads emit brilliant lights when the machine is running, the voltmeter can observe the power generation voltage in real time, and you can also prepare 5V small bulb and connect it to a small generator to light up, which is infinite space for imagination and desire for hands-on experiments.

Excellent Craft: The surface of the machine is exquisitely treated and rich in metallic luster. The parts are matched with high precision. It is equipped with a butane gas fuel tank. The machine runs smoothly and reliably.

Tips: Use butane gas (not included) for fuel, and use pencil lead to smear the piston for lubrication. It is forbidden to add

other oils such as kerosene, gasoline, liquor, etc. Do not Contact the heated parts at will during the operation to prevent burns.
