Inspecting controller components
Do not touch any electrical component with the truck in conduction. When it is necessary to touch
an electrical component for any reason, such as inspection or maintenance, disconnect the battery
connectors and wait for more than 2 minutes before starting the operation.

truck from moving accidentally when the motor suddenly starts rotating for any reason.
In addition, use caution to prevent your body from touching the tires.
