Attention: special tips
When a higher step or obstacle is encountered on the ground to block the wheel and when the
upper slope is over, 还要踩死脚踏板硬闯的时候，because the motor torque is not enough to
pass, in order to protect motor, the controller will start overload protection, failure of pedal
walking function. relieve overload protection method is: turn off the power switch and wait 2
minutes, then restart. If the machine cannot pass the obstacle, please use the handle in the
figure 14 indicating dial up. Think of a way to use human resources.
