How to operate a Mi-T-M power washer. Pressure washing tips.

What happens here

After all hoses are connected, attach the desired quick-release nozzle to the end of the spray wand. Before starting the power washer engine, it is critically important to purge all air from the water lines. To do this, hold the trigger on the spray wand while the water source (e.g., a garden hose) is turned on. Continue to hold the trigger until a steady, uninterrupted stream of water flows from the nozzle. This indicates that all air has been expelled from the pump and hoses.

Goal: Properly attach the nozzle and remove air from the water lines

What they say

Hide

one just screws right on. And that's uh the MITM power washer with a Honda engine. And the whole engine is pretty typical of all Honda engines and stuff. The power washer's got a quick release on the end here. We're going to put a quick release nozzle on just like that. It goes on and off. Once you hook up your power source, you always want to run water through it until it water is completely coming out. Purge all air. There's any air in the line, it'll come out. If there's air in the line, when the power washer is running, the water won't come out. So, you want to purge all the line, all the water, the air out of the line. Once you see that it's water, then you want to put your tip on. You want to make sure your tip is on when you start the engine. And it's a lot easier to start the engine if you're pulling the trigger and holding the trigger like this. If you don't pull the trigger, there's a lot of pressure behind the engine um when you actually go to start it. So, it's in the on position. Everything's ready to go.
