The pressure washer must be on a flat surface so it is stable when you use it. Attach the wand to the pressure washer by hand. The wand is threaded and must be turned clockwise to tighten it down in place. Do not turn the wand counter-clockwise or try to push the wand down in place. Tighten it like you are tightening down a screw.
Pick up the wand and press carefully on the trigger after the pressure washer has been turned on. Point the wand away from the area where you will be pressure washing to test out how it works. Do not begin pressure washing until you have tested the wand. Verify that it is not leaking where it is attached to the pressure washer. If it is leaking, turn off the pressure washer and tighten the wand further. If the leak persists, the pressure washer or wand may need to be replaced.
Aim the wand directly at the area you will be pressure washing, beginning at any bottom corner. Do not position the wand directly in the center and work out from there. Start at a bottom end and work side to side. Hold the want 3 to 4 feet away from the surface you are washing. Do not get any closer or the water will spray back in your face. Press down on the trigger and achieve a steady flow. If the pressure gets too fast, release the trigger slightly, do not press harder.
Hold the wand at a slight downward angle. Do not hold it straight out. Work from the bottom up in a horizontal motion. Do not move the wand vertically. Wash in small sections and do not let the detergent from the pressure washer sit for more than 10 minutes before rinsing it off with the wand. Alternate between cleaning and rising so the soap doesn't stay on the house too long. Avoid tackling too big of an area at one time
