If there is a strong jerky feeling, check whether the connecting rod is connected properly and whether there are oil stains and dust in the cylinder body. If there are any, please use toilet paper to wipe off any unevenness. It is normal to feel pressure rebound in the cylinder body when the flywheel is turned, and the cylinder body is sealed. 2、 Thread the alcohol lamp cotton thread from the packaging bag into the metal lamp cap. 3、 Please go to the pharmacy to purchase alcohol with a purity of 95%. Anhydrous industrial alcohol has a better effect. Fill the alcohol lamp to less than two-thirds. 4、 Move the alcohol lamp to the alcohol lamp holder, and while ensuring safety, light the alcohol lamp for about 2 minutes before turning the flywheel until it automatically runs. The preheating time with a generator is slightly longer, and the entire heating process should not be touched by hands. 5、 The LED indicator light can be directly inserted into the generator output interface. If it does not turn on, exchange the positive and negative poles, and the long leg of the LED is the positive pole. ● Precautions 1、 During the heating process of the model, do not touch the test tube and the metal connected to it with your hands to avoid scalding. 2、 If the alcohol lamp is lit for a long time, it should not be easily touched to avoid burns. 3、 When adding alcohol, the alcohol lamp must be turned off. 4、 This model is not suitable for children under 4 years old. Children under 8 years old should use it under adult supervision to prevent high-temperature burns. 5、 When heating, do not touch the cotton thread of the alcohol lamp with the test tube. When the lamp core burns, water will be generated, and if touched, it may cause the test tube to crack. 6、 The moving parts at both ends of the connecting rod need to be regularly lubricated with oil, and the piston cannot be oiled, otherwise the resistance will be high and it will not run. 7、 Children, please operate safely under the supervision of parents. 8、 When the model rotates, it will vibrate. Be careful to prevent the model from falling off the desktop.
