How Do I Use A Power Washer

The most core steps are actually just a few: first, connect the water source; then, choose the right sprinkler head according to the task (generally, it is recommended to start with a wide-angle sprinkler head of 25 °or 40° for washing driveways or exterior walls, and as for 0° or rotating sprinklers, Unless it is a very difficult small area stain, do not use it easily); if you need to add detergent, remember that it can only be added through a special agent tank or suction pipe, and never fill it directly into the high-pressure pump; before starting the fire, be sure to remove the system air first, That is, without connecting the nozzle, pull the spray gun wrench to drain the water for 30 seconds; start the machine; finally, operate it safely, hold the spray gun tightly with both hands, maintain a distance of 2-3 feet and shoot smoothly to prevent damage to the surface. Goggles, gloves, and overalls are standard, of course. After the work is done, remember to shut down the machine correctly: turn off the power and water sources, pull the wrench to relieve the excess pressure, and drain the accumulated water to prevent the machine from freezing in winter.

Establish A Solid Water Connection

Water source connection is the foundation of all work, the water flow is unstable and the machine will soon have problems. Connect the standard garden hose to the machine water inlet first, remember to check that the connection is tight, if the leak will cause pressure fluctuations, this will hurt the machine. Then connect the high-pressure pipe to the water outlet. It is important to check whether the O-ring in the high-pressure pipe is intact before operation. Even a slight crack may cause water spray and injury during operation.

Choose The Right Sprinkler Head

Choosing the wrong nozzle is the most common mistake made by beginners. Too much pressure can ruin wood or walls.

40° White showerhead: The mildest pressure, suitable for delicate tasks such as washing windows or washing cars.

25° Green sprinkler: It is considered an “all-rounder” and basically relies on it to wash exterior walls, decks or patios.

0° Red nozzle: Except for dealing with that extremely stubborn paint or dirt on concrete, you can basically put it away on a regular basis and definitely don’t use it on wood or painted surfaces.

Spinning/Turbo Sprinkler: A great tool for clearing driveways, but keep your hands steady and keep shaking the strafing, otherwise it will easily leave unsightly etch marks on the surface.

Add Cleaner Correctly

When you encounter stubborn mold or oil, clean water alone is not enough. But you have to be careful that the cleaner must enter through a dedicated cleaner box or straw. Most pressure washers today use the “downstream injection” mode, which means that the soapy water is mixed after flowing out of the water pump. Don’t be smart and add chemicals directly into the pump body. Those strong alkaline or acidic substances will corrode the seals. Once the pump breaks, the repair cost will be enough to buy a new machine.

Remove System Air

Newbies tend to just light the fire, which creates “cavitation” inside the pump. Before turning on the power or pulling the starting rope, first pull the spray gun wrench and let the water flow naturally through the system for about 30 seconds. The air is drained cleanly so that the water pump can be fully lubricated, which can extend the life of the machine for several years.

Start The Fuel Engine And Electric Motor

How you start it depends on your power source:

Fuel: Check the oil and gasoline. Turn the damper to the “on” position, turn the switch to “start”, and then pull the drawstring firmly and smoothly. After the fire, remember to turn the damper back to the “run” position.

Electric model: much simpler. Check that the leakage protection plug is reset, plug it into the socket, and just break the switch.

Safe Operation And Injection Techniques

To protect your property, always hold the gun with both hands to deal with the recoil. When you start spraying, first stay 2 to 3 feet away from the target surface, and then slowly get closer according to the actual effect. Use that smooth strafing motion like “a pendulum” in your technique, and don’t rush at a single point, or you’ll end up with permanent “zebra patterns” or deep pits in the wood or vinyl siding.

Never Neglect Personal Protection

The high-pressure water flow is powerful enough to break through the skin, and this is no joke. I have always stressed that this job requires wearing goggles, wear-resistant gloves, and a pair of thick closed-toe shoes.

Proper Maintenance And Storage After Downtime

How long the machine lasts depends on your last few minutes. After you finish your work, turn off the machine and the faucet first. The most critical step is to pull the airbrush wrench again to release the residual high pressure held in the pipe, otherwise you will have a hard time removing the connector next time. Finally, remove all water pipes and drain any accumulated water. Especially in winter, if there is water in the pump, once it freezes and cracks, the machine will basically be useless.
