Materials: Aluminum alloy+Stainless steel+Thickened glass Features-Engine principle is intuitive, educational toys. Exquisite workmanship made, good for gift presentation as well powerful, ready to run, good for physics teaching demonstration.-Powered by only a small alcohol lamp, you can make it fast rotation and strong power.-As the external combustion engine to avoid the traditional internal combustion engine of the explosion to do work, in order to achieve a high efficiency, low noise, low pollution and low operating costs.-The biggest advantage of the external combustion engine output and efficiency from the influence of altitude, very suitable for high altitude areas. Instructions-The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.-The packing bag of alcohol lamp cotton wear into the metal cap lamp.-Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.-Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.-Led lights can be directly into the generator output interface, if not inserted, the exchange can be positive and negative, led a long foot for the cathode. Safe End Procedure-After use, allow the engine to cool naturally.-After the engine cools naturally, keep the engine out of the reach of small children.-Children in adults under the care of the use of the engine, so as not to burn or break accidentally broken bar injury. Note-Do not touch the baked test tube and the connected metal.-After long time lighting, the alcohol lamp can not be touched.-Suitable for people ≥8 years old, and need to operate under the guardianship.-When heating, do not touch the tube of alcohol lamp tube, combustion will produce moisture, if touched, may lead to tube cracking.-Both ends of the connecting rod joint activities need to add regular oil lubrication, the piston can not refuel, otherwise it will not work the resistance.
