Why is the operation of the lower platform invalid on my Sinoboom Boom Lift?

If the operation of the lower platform is invalid on your Sinoboom Boom Lift, it could be because the key switch has not been turned to the operation of the lower platform. Ensure the key switch is placed on the base frame control position. Also, check if the system has not been powered off after the program was downloaded to the lower platform controller.
