Hi. My name is Matthew Christian, from Tampa Florida and on behalf of Expert Village, I'd like to talk to you about the use and maintenance of a pressure washer. Before you hook up your water supply, as we'll demonstrate in a moment, it's imperative that you bleed your garden hose, or bleed your supply hose, of any air. The pressure washer is designed to pump water -- not air. Having the pressure washer run for a significant period of time with air in the line could potentially damage the pump. It's good practice to bleed the air out of you supply line first. One other thing I'd like to point out that I didn't mention earlier: Again, this is where you pressure side is, where the high-pressure water comes out. This is where you'll hook your hose. Part of this, we've talked about this part, it's called the unloader, it also doubles as a pressure regulator. We can adjust the output of the pressure washer by turning this dial either in or out. Cranking it in, turning it clockwise turns the pressure up; turning it counter-clockwise turns the pressure down. Sometimes you may not need the pressure that the pressure washer is putting out or the pressure is too strong for what you're trying to do. So you can turn the pressure down. Or maybe, the pressure washer's not supplying enough pressure to do the job you're looking to accomplish and you can turn the pressure up.
