How to Start a Power Washer: A Beginner’s Step-by-Step Guide

Ready to blast away dirt and grime? Learning how to start a power washer is your first step to tackling outdoor cleaning projects. This beginner-friendly guide will walk you through the process safely and effectively.

Pre-Start Safety and Setup Checklist

Before you pull the starter cord, proper setup is crucial. Always consult your owner’s manual for model-specific instructions.

Gather Your Equipment and Fuel

You’ll need the power washer, a garden hose, and the appropriate cleaning nozzle. For gas models, ensure you have fresh, unleaded gasoline. Never use E85 fuel. For electric units, verify your outlet is GFCI-protected.

Connect Water and Hose

First, attach your garden hose to the machine’s water inlet. Turn on the water supply fully and let it run for 30 seconds to purge air from the system. This prevents pump damage.

Step-by-Step Starting Procedure

Follow these steps to get your machine running smoothly.

For Gas-Powered Pressure Washers

1. Check the oil level and fill if necessary.
2. Turn the fuel valve to the “On” position.
3. Move the choke lever to “Full Choke” for a cold start.
4. Turn the engine switch to “On.”
5. Pull the starter cord firmly until the engine starts, then move the choke to “Run.”

For Electric Pressure Washers

1. Ensure the unit is plugged into a GFCI outlet.
2. Connect the high-pressure hose and spray gun.
3. Squeeze the trigger on the spray gun to release pressure.
4. Flip the power switch to “On.” The unit is now ready.

Common Beginner Mistakes to Avoid

Steer clear of these pitfalls to ensure a long machine life.

Never run the pump dry. Always have water flowing before and during operation. Use the correct nozzle. The 25-degree (green) nozzle is best for general cleaning. For a more detailed how to start a power washer troubleshooting guide, visit this resource.
