Maintenance guide
1. If it is not used for a long time, please take out the battery in the model car and remote control.
2. Make sure the battery is fully charged before each use.
3. Before or after each use, carefully check whether the circuit wiring of the model car is fastened and there is
no dropped connector. Carefully check whether the wheels are fastened. Loose wheels will cause excessive
wear of transmission shaft, wheel cup or wheel seat.
4. Check whether the transmission gear needs to be lubricated.
5. The idle battery needs to be stored in a dry and cool place after charging (up to 50-60% of the power) to
avoid children's touch.
6. After each use, please carefully check whether all parts of the model car are complete and repair or replace
them in time. Use a fine brush to clean the sand, dirt and other dirt in the model car, and then use a soft
cloth to wipe it clean.
