The key of the 554 rotary cultivator in Shantuo hit a light, but there was no response.

Does the subject want to ask, "What should I do if the key of Shantuo 554 rotary tiller doesn't respond?" ?

1. First, check whether the battery is charged and ensure that the voltage is not low. If the battery is dead, please replace it in time.

2. Secondly, the mixture of the engine can't reach the required air-fuel ratio, so the vehicle can't start and stop. It is necessary to remove carbon deposits from the intake pipe and the throttle idling motor.

3. Finally, the ignition system fails, which will directly cause the engine to fail to start. Checking and repairing the ignition system fault can solve the problem that the key of Santo 554 rotary tiller is unresponsive.
