Mastering the Art of Starting Your Subaru EA175V Pressure Washer: Tips and Tricks from the Pros

If you’ve recently purchased a Subaru EA175V pressure washer, or you’re considering doing so, congratulations! You’re on your way to becoming a master at cleaning tough outdoor surfaces like driveways, patios, and decks. However, if you’re new to pressure washers, starting them can be intimidating. In this article, we’ll guide you through the steps to start your Subaru EA175V pressure washer safely and efficiently.

Safety Precautions

Before you start your pressure washer, it’s important to take safety precautions to keep yourself and those around you safe. Here are some key things to keep in mind:

  • Wear protective gear: You’ll be dealing with high-pressure water, so wear goggles and gloves to protect your eyes and hands.
  • Check for leaks: Before starting your pressure washer, ensure that all hoses are secure and there are no leaks in the machine.
  • Don’t touch the muffler: The muffler gets very hot during use, so never touch it while the engine is running or immediately after turning the machine off.

Priming the Pump

Once you’ve taken the necessary safety precautions, it’s time to prime your pump. The pump needs to be full of water before starting the engine, or you risk damaging the machine. Here are the steps to prime your pump:

  1. Connect the hose to both the pressure washer and the water supply.
  2. Turn on the water supply.
  3. Squeeze the wand trigger to release any air in the hose and pump.
  4. Once water is flowing smoothly out of the wand, turn off the wand and let the water continue to run through the pressure washer for a few more seconds.

Starting the Pressure Washer

Now that your pump is primed, it’s time to start the engine. Here are your steps:

  1. Move the choke lever to the "closed" position.
  2. Turn the fuel valve to the "on" position.
  3. Move the throttle control lever to the "fast" position.
  4. Pull the starter cord sharply several times until the engine starts. Once the engine has started, open the choke fully and let it warm up for a few minutes.

Troubleshooting Common Issues

Sometimes, even with the best precautions, issues can arise. Here are some common problems that can come up and their solutions:

  • Engine won’t start: Check to make sure that the fuel valve is turned on and that there is enough fuel in the tank. If both of these are okay, ensure that the spark plug is connected and clean.
  • Low pressure: Low pressure can be caused by several things, including a clogged nozzle or a dirty water inlet filter. Clean or replace these parts to restore pressure.
  • Leaks: If you notice water leaking from your pressure washer, it could be due to loose fittings or damaged hoses. Tighten or replace these parts as necessary.

By following these simple steps, you’ll be able to start your Subaru EA175V pressure washer with ease. Always remember to take proper safety precautions and follow the manufacturer’s instructions closely. Happy cleaning!
