We are sorry that you are having trouble with your Chapin 4 Gallon 20v Wide Mouth Backpack Sprayer! You should hear the battery running while the unit is turned on, but you should be able to control the spray using the handle to stop and start the flow of liquid from the handle. If something is getting caught in the handle, then you may need to give Chapin a call directly to troubleshoot this issue. You can reach them directly at 800-950-4458. Please let us know if you have any trouble contacting them or need further assistance.
