      NOTE:
      • Check if there is any dirt or mud around the connector before this operation and remove the dirt as necessary.
      • Be careful of mud because the quick connector has an O-ring which seals the pipe and connector that can be contaminated.
      • Do not use any tool in this operation.
      • Do not bend or twist the nylon tube. Protect the connector by covering it with a vinyl or plastic bag.
