How to use
To operate the ER4 Autokar MIX, wind the knob or dedicated winding part according to the toy's design until you feel resistance, then place the car on a flat surface and release. The stored mechanical energy in the spring is transferred through internal gears to the wheels, producing forward motion. For repeated runs, rewind as needed. Use the toy on smooth, level surfaces for best performance and avoid over-winding to prevent stress on the mechanism.
