Hi my name is Matthew Christian from Tampa, Florida and on behalf of Expert Village. Today we are going to talk about the proper use and maintenance of a pressure washer. Okay another item to be familiar with as part of your pressure washer is the wand assembly which consist of a nozzle, the wand and the trigger. Let's take a moment and talk about the nozzle, not all nozzles are created equal. Some nozzles have a larger oral fist or larger hole than others. The reason for that is pressure washers that supply a higher gallon per minute requires a larger oral fist or a larger hole in order to let that water escape at that volume. Again this is 2.2 gallons per minute 2.2-2.4 gallon unit so the oral fist is relatively so small. Another aspect or another consideration in your tip is spray pattern. You can go anywhere from a jet stream to a vary wide fan. This particular is a medium degree fan at 2.2 gallons per minute.
