The wand portion of your pressure washing rig basically refers to the hardened shaft that extends out of the hose that is bringing in your water supply. This wand is firm because it needs to be, since accuracy can become a difficult thing to maintain if all you have to grip is a hose that is flopping around. The wand itself has another attachment on the end called the main tip, and there is a pretty good chance that you would need to keep changing this tip up from time to time.
This is because of the fact that a pressure washing service would need to adjust the width of the spray along with the intensity of the pressure itself. The options range from maximum pressure and concentrated spray to lowest pressure and widest spray, although this latter option is rarely used if ever. The truth of the situation is that knowing how to change the main tip of your pressure cleaning wand is incredibly vital, and since you are a newbie you might be struggling to figure out how this is supposed to be done.
To put it simply, the tip at the end of your wand has been screwed on. That means that you just need to move it in a counterclockwise motion to unscrew it. The fact of the matter is that some pressure washers have clip on tips so if that is the case for yours you might need to pull rather than unscrew. Just see whichever motion feels more natural and doesn’t face resistance and you can always defer to the instructional manual if there are ever any major issues.
