🧰 What You’ll Need Before You Start

  • Your electric pressure washer (obviously)
  • A garden hose with good water flow
  • Heavy-duty extension cord (if needed)
  • Safety glasses and closed-toe shoes
  • A little patience—trust me, it’s worth it

⚡ Step-by-Step: First-Time Setup

1. Read the Manual (Yes, Really)

I know, manuals aren’t thrilling. But each washer’s a little different, and you don’t want to miss key setup tips or safety warnings.

2. Connect the Water Supply

Hook up your garden hose to the washer’s water inlet. Make sure it’s snug—leaks are annoying and waste pressure.

3. Plug It In

Use a grounded outlet and a heavy-duty extension cord if needed. Don’t plug it into a sketchy power strip or flimsy cord.

4. Choose Your Nozzle

Most washers come with multiple spray tips (0°, 15°, 25°, 40°, and soap). Start with the 25° or 40° tip for general cleaning. The 0° tip is like a laser beam—great for stubborn stains but risky on paint or soft surfaces.

5. Turn on the Water First

Before powering up the washer, turn on the water supply. This prevents dry running, which can damage the pump.

6. Power It Up

Now flip the switch and let the motor hum to life. You’ll feel the pressure build in the hose—don’t freak out, that’s normal.


🧼 Let’s Clean Something!

Start with a test spray on a small area. Hold the wand about 2 feet away and move in smooth, overlapping strokes. You’ll get the hang of it fast.

Want to wash your car? Use the soap nozzle or foam cannon if your model has one. Just make sure to switch to a wide-angle tip (like 40°) for rinsing so you don’t damage the paint.


🛑 Pro Tips to Avoid Rookie Mistakes

  • Don’t aim at people, pets, or windows.
  • Never use the 0° tip on wood, siding, or vehicles.
  • Keep the cord and hose away from sharp edges or hot surfaces.
  • If the washer shuts off unexpectedly, check for clogs or overheating.

🧽 Wrap-Up and Storage

When you’re done, turn off the washer, unplug it, and shut off the water. Squeeze the trigger to release leftover pressure. Coil the hose and cord neatly, and store everything in a dry spot.
