How do I adjust the dial of the water soap container for a full car wash?
Before you add any water in the container, be sure the dial is closed all the way. When you fill up water and car wash soap, close the lid and place the wash head on the surface of your car. You may then turn the dial towards open direction for about one and half thumb intervals only. Be sure the water soap drops slowly so it can provide a full car wash without refilling. It is important you host the dirts off your car before using the power washer and keep your car wet during washing.
