.Instructions: 1. The steam engine is a reciprocating power machine that converts the energy of steam into mechanical work.
2. Lubricating oil should be dropped at each friction point of the nose before operation. Add water into the boiler and heat it until it boils. Then gently twirl the flywheel until it runs automatically. (If getting stuck, maybe 1, the pressure is insufficient; 2, cylinder and piston lubrication are not enough; 3, the cylinder and piston running is not in place.)
3. The boiler is not included, please prepare or purchase by yourself. You can also consult us to buy matching boilers.
