Instructions:
1. The double cylinder model is in a horizontal position, the placement surface is as clean as possible, and the friction of the rubber pad is increased to increase the stability of the engine.
2. Install the matching alcohol lamp, keep away from flammable objects, wait 30 seconds after lighting the alcohol lamp, and rotate the flywheel slightly.
3. LED lights flash when the engine is running normally
4. When the double cylinder model is running and for a period of time after the end, it is strictly forbidden to touch the heating cylinder to avoid burns.

Points to consider:
1. This product is suitable for people over 14 years old, and children must be accompanied by adults
2. Because alcohol is a liquid, it cannot be transported by express delivery, please understand! Alcohol can choose pharmacies to purchase alcohol with a purity of 75% and above
3. The one-time operation time should not be too long, preferably less than one-third of the vial of the alcohol lamp;
4. When the product has just been shipped, the test tube is in a high temperature state, and it is strictly forbidden to contact with skin and flammable objects! Also try to avoid contact with alcohol wicks to prevent the cylinder from bursting
5. Shafts and connecting rods cannot be lubricated with oil. Once grease is generated, the friction is very large and can be lubricated with a pencil lead.
