In the production process, the first brain conception, and then hand-made, this process strengthens the children's imagination.

Let the children understand the knowledge of scientific principles, easy to install and easy to operate.

Product Principle:
two stage acceleration hand crank generator production kit involves gear combination, deceleration and electrical energy conversion and other physical knowledge principles, shaking the hand crank, through the large gear drive pinion acceleration, and then through another large gear drive motor pinion secondary acceleration, high-speed rotation of the motor issued by the DC power, so that a light bulb lit up or make the small fan turn up! It is the performance of mechanical energy into electrical energy.

The product belongs to the parts assembled, the picture is assembled finished product, buyers receive the product is a package of parts package, need to do their own hands and brains to learn to complete the production.

Product does not contain batteries !

Description of different versions.
- Light Version, can be made to light up with electric beads

NOTE：
Installation is not complicated, but requires care and patience. The difficulty of this group of models may have the problem of gear bite too tight, too loose, need to be adjusted; Shaking should not be too fast, easy to cause the gear bite shaking; With the use of the spindle will wear out, there will be noise.

Instruction Manual Supplement.
Due to the limited layout of the instruction manual, there are only complete instructions for making the light version, if you buy the fan version, making the fan version starts from step 7 of the instruction manual, and then follow the following 4 steps to complete:
1. Use short screws to fix the angle iron
2. Use the medium screws to mount the motor on the T-bar
3. Press the insertion wire and mount the T-bar with the short screw.
4. Insert the fan blade

Attention: 
1. The mounting position of the fan can be customised.
2. Because it is a small motor, can't take lamp bead and fan at the same time.
3. Please shake slowly, not violently shaking, gear bite to prevent shaking
4. Shaking process there is bite noise, at the same time with the use of time, the shaft will wear, so there is resistance and noise
5. If you can not shake, the bite is too tight, find out the reason, generally can be gently break the motor bracket, slightly loose screws and so on.
