usage method: move the flywheel by hand to see whether it is smooth or not. Adjust the relevant screws (adjusted before sale). check whether the sliding parts are clean. fill the alcohol lamp to less than two-thirds. Please note that 95% medical purity alcohol is the best. light the alcohol lamp and put it in the front of the test tube. About 1 minute later, turn the flywheel and the engine rotates. The preheating time with generator is slightly longer. matters needing attention: do not touch the baked test tube and the metal connected to it to avoid scalding. ignite the alcohol lamp for a long time, and the alcohol lamp should not be touched easily to avoid scalding. it is suitable for children over 8 years old and adults, and it needs to be operated under the escort of adults under 8 years old. when heating, the cotton thread of alcohol lamp should not touch the test tube, and the piston should not be refueled. both ends of the connecting rod need to be lubricated, but the piston cannot be lubricated. please operate safely under the supervision of your parents. the rotating speed of the model is high to prevent vibration and falling to the ground. the lamp core line should not be too long, but should be cut short.
